Procurement in Oil & Gas in Malaysia – End-to-End Process, Contracts, and Best Practices

Oil and gas procurement is the disciplined process of specifying, sourcing, contracting, expediting, inspecting and delivering the materials, equipment and services an energy asset needs, from valves and pumps to inspection services and heavy-lift transport. In Malaysia it operates inside a licensed vendor ecosystem anchored on PETRONAS and its contractors, with strong local-content expectations, island-and-offshore logistics, and demand that arrives in project-shaped waves rather than a steady stream. Unlike general purchasing, it is judged on schedule certainty and documentary traceability at least as much as on unit price.

Key facts

Two spend types	CAPEX — project-driven, one-off, engineered to specification. OPEX — repeat operational and maintenance spend, catalogue-driven, high transaction volume.
Two buying channels	Project procurement (inside an EPC/EPCC scope, schedule-critical, MDR-heavy) and operations procurement (production support, spares, consumables, services).
Core documents	RFQ / ITT, technical bid evaluation (TBE), commercial bid evaluation (CBE), purchase order (PO), expediting reports, Manufacturing Data Record / dossier (MDR), Inspection and Test Plan (ITP).
Core KPIs	OTIF (on time in full), quoted vs actual lead time, cost variance against estimate, NCR rate, vendor scorecard, PR-to-PO cycle time.
What breaks projects	Late scope freeze, late award of long lead items, weak TBE discipline, and MDR requirements discovered at handover instead of at RFQ.

Why oil and gas procurement is different from general procurement

Anyone who has moved from FMCG or general manufacturing into energy notices the difference in the first week. The tools look familiar — requisition, quote, evaluate, order — but the weighting of the decision is inverted.

Lead times run in months, not weeks

A commodity buyer optimises price against a short replenishment cycle. An oil and gas buyer is often working with items whose delivery is measured in quarters. Large centrifugal compressor trains, gas turbines, custom-engineered pressure vessels, HV switchgear, subsea trees and long-lead line pipe can carry lead times from several months to well beyond a year depending on the vendor’s order book and the level of engineering involved. Once the market tightens, quoted lead times stretch quickly and slot reservation becomes a negotiation in itself.

That single characteristic reshapes everything downstream. It means the procurement decision has to be made before the engineering is fully mature. It means a saving of a few percent on unit price is worthless if it costs six weeks on the critical path. And it means the buyer’s most valuable skill is not negotiation — it is knowing which items must be committed early and having the confidence to push for that commitment while the design is still moving.

Criticality is not evenly distributed

Two items on the same requisition can carry wildly different consequences. A gasket set that fails is an annoyance. A relief valve that fails is a safety event. Procurement in this industry has to carry a criticality rating through the whole process — into the specification, the vendor selection, the inspection level, the documentation package and the spares strategy. Buying both items the same way is the most common structural error in an immature procurement function.

QA/QC and traceability are part of the product

In most industries you buy a thing. In oil and gas you buy a thing and its evidence. Material test certificates traceable to heat number, welder qualifications, NDT reports, positive material identification, hydrotest records, calibration certificates, painting and coating records — the paperwork is not administrative overhead, it is what allows the asset to be operated, inspected and insured for the next thirty years. An item that arrives physically perfect with an incomplete data book is, for practical purposes, not delivered.

This is why the documentation requirement belongs in the RFQ, priced and agreed, and not raised as a surprise during close-out. More on this under MDR.

HSSE and compliance expectations extend into the supply chain

Operators are accountable for what happens on their sites, including work performed by vendors and sub-vendors. That accountability flows backwards into prequalification: safety statistics, HSE management systems, competency records, working-at-height and lifting certifications, and increasingly sanctions screening, anti-bribery compliance and ESG or Scope 3 reporting expectations. A vendor who cannot evidence these is a liability regardless of price.

Teams building this capability often start with structured coverage of the whole supply chain function — the Purchasing & Procurement in the Upstream Oil & Gas Supply Chain course covers how procurement, logistics and materials management interlock, which is the part most self-taught buyers are missing.

Procurement sits on the critical path

In an EPC or EPCC project, the procurement schedule is the project schedule for long lead items. Engineering can be recovered with more engineers. Construction can sometimes be recovered with more crews and more shifts. A twelve-month equipment lead time cannot be recovered with anything except money, and often not even then. The procurement manager who understands this behaves differently: they chase the requisition, not the quote.

The end-to-end procurement lifecycle, step by step

This is the backbone of the discipline. Each step exists because a project somewhere failed without it.

1. Demand definition and scope freeze

Everything downstream inherits the quality of this step. The requisition package should contain the datasheet, the applicable specifications and codes, the criticality rating, the required delivery date, the inspection level, the documentation requirement, and the spares philosophy.

The recurring failure is issuing an RFQ against a datasheet that engineering still intends to revise. Vendors quote against a moving target, bids become incomparable, and the eventual variation order costs more than the original item. A scope freeze is not bureaucracy — it is the point at which the organisation agrees to stop paying for its own indecision.

Practical rule: if engineering cannot freeze, buy the engineering time explicitly. A paid vendor front-end engineering study is cheaper than a change order after fabrication starts.

2. Category strategy and sourcing plan

Before touching a supplier, decide how each category should be bought. Categories differ on two axes: value at risk and supply market complexity.

• High value, few capable suppliers (rotating equipment, subsea hardware, HV electrical): relationship-led, early engagement, frame agreements, long negotiation cycles.
• High value, many suppliers (bulk piping, structural steel, cabling): competitive tendering, volume leverage, careful mill and origin control.
• Low value, few suppliers (proprietary spares, OEM-locked instruments): secure availability, negotiate framework pricing, manage obsolescence.
• Low value, many suppliers (consumables, general hardware): automate. Catalogue, call-off order, minimum human involvement.

The sourcing plan then sets the sequence: what gets committed in month one, what waits for IFC drawings, what can be bought locally, what must be imported, and where the float sits.

3. Vendor prequalification and the Approved Vendor List

Prequalification answers a single question: is this company capable of doing this scope, at this quality level, in this timeframe, without creating risk for us? It is not the same as selection, and mixing the two is a classic mistake — a prequalification questionnaire is not a place to negotiate price.

In Malaysia, the operator-side ecosystem adds a layer. Vendors supplying into the PETRONAS ecosystem generally need to be licensed and registered under the relevant product and service codes, and contractors frequently maintain their own approved vendor lists derived from that base. Registration requirements, category codes and portal processes change from time to time, so treat the current official requirements as the authority rather than internal folklore, and check them at the point of qualification.

Beyond registration, the AVL should be a living instrument: entries expire, categories are scoped (“approved for API 610 pumps up to X” is useful; “approved for pumps” is not), and performance data feeds back in.

4. RFQ / ITT issuance

A good enquiry package is boring and complete. It contains:

• Commercial instructions to bidders, with the bid due date, validity period, and the submission format
• Scope of supply, with a clear statement of what is excluded
• Technical datasheets and applicable specifications, revision-controlled
• Inspection and test requirements, including who witnesses what
• Documentation requirements (the MDR index) and the delivery schedule for documents
• Delivery terms, named place, and Incoterms® rule with version
• Draft terms and conditions, so that legal review happens before award, not after
• The evaluation basis — stated openly enough that bidders quote comparable things

Split technical and commercial submissions. If the technical evaluators can see prices, the technical evaluation is compromised, whatever anyone says. This is the single easiest structural improvement most teams can make.

5. Technical bid evaluation (TBE)

TBE establishes which bids are technically acceptable — not which is best value. Its output is a compliance position for each bidder: fully compliant, compliant with clarifications, compliant with accepted deviations, or non-compliant.

The discipline that separates good TBE from bad:

• Deviation registers, not impressions. Every deviation logged, assessed for impact, and either accepted or rejected in writing.
• Technical equalisation. If bidder A includes a spare rotor and bidder B does not, the difference must be priced before commercial comparison, or the CBE is meaningless.
• A named evaluator per discipline. Rotating, process, materials, electrical, instrumentation, and QA/QC each own their section.
• Scoring criteria fixed before bids open. Weightings decided afterwards are weightings decided to suit a preferred bidder.

6. Commercial bid evaluation (CBE)

Only technically acceptable bids proceed. CBE compares total evaluated cost, not quoted price:

• Base price plus technical equalisation adjustments
• Freight, insurance, duty and clearance to the named delivery point
• Payment terms converted to a present-value basis
• Inspection, third-party and expediting costs
• Spares and commissioning support, if not in base scope
• Cost of delay, where lead times differ materially
• Currency exposure and price validity or escalation terms

A bid that is 4% cheaper ex-works and eight weeks later is usually the more expensive bid. Making that visible in the CBE is how procurement earns its seat at the project table.

The evaluation and negotiation skillset here is teachable and is covered in depth in the Mastering Contract Law and Risk Mitigation in Energy programme, which runs from contract formation through to dispute resolution.

7. Negotiation and award

Negotiate the things that actually carry risk: delivery date and the consequences of missing it, liability and warranty, payment milestones, documentation, inspection access, spare parts pricing held open for a period, and the change mechanism. Price is one variable among several and rarely the one that determines project outcome.

Award should be accompanied by a documented recommendation to award: the trail from requisition through TBE and CBE to the decision. Malaysian and international operators alike audit this, and a decision that cannot be reconstructed two years later is a governance finding waiting to happen.

8. Purchase order and kick-off meeting

The PO is the contract. It should incorporate, by explicit reference and with a stated order of precedence, the agreed technical scope, the deviation register as accepted, the ITP, the MDR index, the delivery terms and the commercial conditions.

Then hold the kick-off. For any significant engineered item, a kick-off meeting within two to three weeks of award pays for itself many times over. Agenda: confirm scope and revision status, confirm the document submission schedule, agree the manufacturing schedule and key milestone dates, confirm inspection hold and witness points, name the expeditor and the vendor’s counterpart, and agree the escalation route. Skipping kick-off is how a project discovers in month five that the vendor was waiting on a drawing approval nobody knew had been submitted.

9. Expediting and inspection

Expediting is not chasing. It is the systematic verification that the vendor’s actual progress matches the plan, early enough to act.

• Desk expediting: scheduled written status reports against milestones.
• Field expediting: physical visits to the works to verify progress against the manufacturing schedule.
• Sub-vendor expediting: the raw material or the sub-supplied component is very often the real constraint. A vendor on schedule whose forging supplier is not is not on schedule.

Inspection runs alongside, governed by the ITP. The ITP defines each activity, the applicable procedure and acceptance criteria, and the intervention level for each party: W (witness — notified, may attend), H (hold — work may not proceed without attendance), R (review of records), M (monitor). Hold points must be honoured; a hold point routinely waived is not a hold point, and the discipline erodes quietly until an inspection release is issued for something nobody saw.

Factory acceptance testing (FAT) is the last practical opportunity to reject a non-conforming item cheaply. After it ships, every remedy costs more.

For teams building inspection and integrity competence alongside procurement, the API 570 Piping and Pipeline Inspectors Preparatory Course and the wider Equipment, Facilities and Maintenance course area cover the technical side of what inspectors are actually verifying.

10. Logistics, customs and delivery

Malaysia’s geography makes this a discipline rather than an afterthought. Port Klang, Johor and Bintulu handle very different flows; East Malaysia adds a sea leg; offshore adds a supply base, a vessel window and weather risk. Monsoon seasonality affects offshore campaign windows and should be visible in the procurement schedule, not discovered by it.

Practical points that repeatedly bite:

• Incoterms® rule and named place must be precise. “CIF Malaysia” is not a delivery term. “CIF Port Klang, Incoterms® 2020” is.
• Import documentation must be prepared before the goods sail, not on arrival. Missing certificates of origin, incorrect HS classification and mismatched packing lists cause demurrage and storage charges that dwarf the freight saving that prompted the routing.
• Duty and tax treatment varies by item, end use and location — free zones, licensed manufacturing warehouses and petroleum-related reliefs each have their own rules and conditions. Get a customs opinion for high-value or unusual consignments rather than assuming precedent applies; the rules are periodically revised.
• Preservation starts at the factory. Equipment sitting in a laydown yard in a tropical climate degrades. Preservation requirements, spare desiccant, rotation regimes and storage classification belong in the PO.
• Heavy lift and out-of-gauge cargo needs route survey and permitting lead time that often exceeds the manufacturing lead time for the trailer-limiting component.

Relevant learning: Offshore & Marine Supply Base Operations Management, the Design, Planning and Executing in Heavy Lifting VILT, and the self-paced International Freight Forwarding and Offshore Logistics Operations e-learning modules.

11. Receiving, NCR handling and close-out

Goods receipt is a control point, not a formality. Verify identity and quantity against the PO, check for transit damage, confirm the documentation package is present, and tag and store the item under the correct preservation regime.

When something is wrong, raise a non-conformance report immediately. An NCR should record what was found, against which requirement, the disposition (use-as-is, repair, rework, reject), who authorised that disposition, and the corrective action. Informal resolution — a phone call, a favour, an undocumented rework — leaves the asset with an undocumented deviation that surfaces years later during an integrity review.

Close-out means: all goods received and accepted, all NCRs dispositioned and closed, the complete MDR received and accepted, warranty start date recorded, final payment released, retention scheduled, and the vendor’s performance scored.

The materials side of this — receipt, preservation, warehousing, stock optimisation, obsolescence — is a discipline of its own, covered in Materials Management and Lean & Sustainable Warehouse Management in Oil & Gas.

12. Vendor performance review

Score every significant order, on a consistent basis, and feed the result back to the AVL. Without this loop, prequalification becomes a snapshot from whenever the vendor was first approved, and buyers keep placing orders with suppliers whose recent performance nobody has aggregated.

Procurement organisation models in Malaysia

Centralised

A single procurement function serves all projects and operations. Strengths: leverage across volumes, consistent process, deeper category expertise, easier governance. Weakness: distance from the project. Central teams can be slow to respond to a fast-moving execution schedule, and project managers start finding workarounds.

Best fit: operators and asset owners with steady OPEX volume and repeatable categories.

Project-based

Procurement staff are embedded in the project team, reporting into the project manager. Strengths: responsiveness, ownership of the schedule, tight interface with engineering. Weakness: category knowledge and supplier relationships walk out the door at project close-out, volumes are fragmented, and process consistency varies with the individual.

Best fit: EPC and EPCC contractors executing discrete large scopes.

Hybrid

The model most mature organisations converge on. A central function owns category strategy, frame agreements, the AVL, systems and governance. Project procurement teams execute against those frameworks with delegated authority and a clear escalation path.

The hybrid only works if the boundary is written down. The recurring friction is authority: who can accept a technical deviation, who can approve an expedite premium, who can commit before the requisition is fully approved. Decide it in advance.

Frame agreements versus spot buys

Use a frame agreement when	Use a spot buy when
Demand is repeating and reasonably predictable	Demand is one-off or genuinely unique
Lead time protection or slot reservation matters	The item is available and commoditised
Specification is stable across orders	Specification is engineered per application
Transaction volume makes per-order tendering wasteful	Market pricing moves enough that lock-in costs money
You want a pre-agreed change and rate mechanism	You want to test the market

Frame agreements decay. Review pricing, scope and the supplier’s continued suitability on a fixed cycle, or you will discover in year four that the “agreed” rates are 20% above market.

Interfaces that determine whether procurement works

• Engineering — owns the specification and the deviation decision; procurement owns the market reality. The relationship works when engineering is told what a requirement costs in time and money before it is frozen.
• QA/QC — sets the inspection level and reviews the MDR. Involve them at RFQ, not at delivery.
• Construction — owns the required-on-site date and the sequence. Their sequence, not the PO date, is the real deadline.
• Commissioning — needs vendor support, commissioning spares and the O&M documentation. These are the most commonly omitted line items in an entire procurement scope.
• Finance — payment terms, bonds, currency exposure, and cash flow against the milestone schedule.

Project-side skills that make these interfaces work are covered in the Project Management Professional (PMP)® preparation course and Oracle Primavera P6 Professional for the scheduling side.

Category deep dives

Each category below carries its own risk profile, specification burden, lead time behaviour and documentation set. Treating them uniformly is the fastest route to trouble.

Rotating equipment (pumps, compressors, turbines, drivers)

Risks: long lead times driven by casing and rotor manufacturing; performance guarantees that are difficult to prove after installation; vibration and reliability issues that only surface in service; sub-vendor dependency for seals, couplings, gearboxes and drivers; obsolescence over the asset life.

Specification anchors: API 610 (centrifugal pumps), API 617 (axial and centrifugal compressors), API 611/612 (steam turbines), API 614 (lubrication systems), API 682 (mechanical seals), plus project-specific datasheets covering duty point, NPSH, materials, and driver interface.

Lead times: typically the longest of any mechanical package on a project; highly sensitive to vendor order book and to any engineered change.

Documentation to specify at RFQ: performance curves, mechanical run test and where applicable string test procedures and reports, rotor dynamic analysis, material certification, hydro test records, noise data, weld procedures, coating records, spare parts interchangeability record, IOM manuals.

Buying advice: commit early, resist late duty-point changes, and price the mechanical run test and any string test explicitly. Witness the FAT — it is the only realistic chance to catch a problem before it becomes an installed problem.

Related learning: Rotating Equipment (VILT) and Maintenance of Rotating Equipment.

Valves and actuators

Risks: enormous quantity and variety on a typical project, which makes bulk handling tempting and dangerous; counterfeit and mis-certified product in the grey market; seat leakage class disputes; actuator sizing mismatches; fugitive emission compliance.

Specification anchors: API 6D, API 600/602, API 608, ANSI/FCI 70-2 seat leakage classes, ISO 15848 for fugitive emissions, ASME B16.34, plus material class, trim selection, end connections, and fire-safe requirements where applicable.

Lead times: short for standard commodity valves; long for large bore, high pressure class, exotic materials, severe service control valves and anything requiring cryogenic or fire-safe testing.

Documentation: material test certificates traceable to heat, pressure test and seat leakage certificates, fire-safe certification, actuator sizing calculations, fugitive emission test reports, PMI records.

Buying advice: separate commodity valves from severe-service and safety-critical valves and buy them through different processes. Insist on traceable certification from an authorised channel — the price differential against grey-market supply is small compared to the consequence of an uncertified body in hydrocarbon service.

Related learning: Control Valves and Actuators (VILT).

Piping, fittings and line pipe

Risks: mill capacity and allocation; material substitution; heat traceability failures; coating damage in transit; over- or under-ordering bulk quantities as the MTO matures.

Specification anchors: ASME B31.3 and B31.4/B31.8 as applicable, ASTM and API 5L material grades, ASME B16.5/B16.9/B16.47 for fittings and flanges, project coating and insulation specifications.

Lead times: commodity carbon steel is usually available; alloy, duplex, super duplex, cladded and large-diameter pipe is mill-slot dependent and can extend significantly when demand is high.

Documentation: EN 10204 3.1 or 3.2 certificates as specified, heat traceability records, NDT reports, coating and lining records, PMI.

Buying advice: manage the material take-off maturity explicitly. Buying bulk quantities against a 60% MTO and topping up later is normal — pretending the 60% MTO is final is not. Agree a top-up mechanism and pricing at the original award.

Electrical and instrumentation

Risks: hazardous area certification mismatch; interface and integration failures between packages; obsolescence of control and instrument systems over a long asset life; software licensing and cybersecurity requirements arriving late; HV switchgear and transformer lead times.

Specification anchors: IEC 60079 series for explosive atmospheres (Ex ratings, gas group, temperature class, ingress protection), IEC 61511 / IEC 61508 for functional safety and SIL, IEC 61439 for assemblies, plus project instrument index and I/O schedule.

Lead times: HV switchgear, large transformers and complex control systems can run long; instrumentation is generally shorter but is highly sensitive to late datasheet change.

Documentation: Ex certificates matched to the exact model and configuration supplied, calibration certificates traceable to standards, FAT and where required SAT procedures and reports, loop diagrams, software version records, SIL verification documentation.

Buying advice: verify that the Ex certificate matches the item actually supplied, including options and accessories. A certificate for a similar model is not a certificate. For safety instrumented systems, involve the functional safety engineer at TBE — commercial staff cannot evaluate SIL compliance.

Static equipment (vessels, exchangers, tanks, columns)

Risks: fabricator capability and workload; welding qualification and repair rates; dimensional and nozzle orientation errors discovered at site; transport envelope constraints; code stamp and third-party inspection requirements.

Specification anchors: ASME BPVC Section VIII Div 1 or 2, TEMA for shell-and-tube exchangers, API 650/620 for storage tanks, plus project fabrication and NDT specifications.

Lead times: driven by plate and forging availability, fabricator slot, and the extent of NDT and PWHT.

Documentation: the classic full data book — design calculations, as-built drawings, material certificates, welder and WPS/PQR qualification, NDT reports and radiographs, PWHT charts, hydro test record, nameplate rubbing, code data report where applicable.

Buying advice: audit the fabricator, not just the sales office. Weld repair rate history, NDT resourcing and current shop loading tell you more about delivery certainty than any commercial reference.

Inspection services and NDT

Risks: inspector competence and certification currency; independence and conflict of interest where the vendor pays the inspector; coverage gaps when inspection is scoped by day rate rather than by activity; report quality and turnaround.

Specification anchors: ISO 9712 or SNT-TC-1A personnel certification, ISO/IEC 17020 for inspection bodies, plus the technique-specific procedures referenced in the ITP.

Buying advice: buy inspection against the ITP, not against a day rate. Specify the required certification level per technique, require CVs and certificates before mobilisation, and set a report turnaround obligation with teeth. Inspection reports delivered three weeks after the event have no expediting value.

Related learning: Pipeline Integrity Management.

Logistics, freight and heavy lift

Risks: route and permit constraints for out-of-gauge cargo; port and yard capacity; vessel availability and weather windows for offshore delivery; customs clearance delays; lashing, sea-fastening and transit damage; insurance gaps at handover points.

Buying advice: engage the logistics provider during engineering, not after fabrication. The transport envelope is a design input for anything large. Run a route survey early for heavy or oversized items, and confirm that the receiving facility can actually lift what is arriving. Match the Incoterms® rule to where you want risk to transfer and where you have the capability to manage it — buying DDP because it is administratively easy means paying someone else to manage a risk you may be better placed to control, or vice versa.

Related learning: Design, Planning and Executing in Heavy Lifting (VILT) and Introduction to Upstream Logistics (e-learning).

Chemicals and consumables

Risks: shelf life and degradation; storage and segregation requirements; hazardous goods transport classification; supply continuity for production-critical chemicals; disposal obligations.

Documentation: safety data sheets, certificates of analysis per batch, dangerous goods declarations, batch traceability.

Buying advice: structure as call-off contracts with agreed replenishment triggers and consignment stock where the chemical is production-critical. Verify batch COA against specification on receipt rather than on trust — off-specification chemical injected into a live process is an operational problem, not a commercial one.

Services and manpower contracts

Risks: scope creep in reimbursable arrangements; competency of supplied personnel versus CVs submitted; HSE performance of the contractor’s crew; back-to-back liability with the operator’s contract; payroll and permit compliance for foreign personnel.

Buying advice: define deliverables and acceptance criteria, not just headcount and rates. Where personnel are supplied, retain the right to reject and replace. Audit timesheets against actual site presence for reimbursable scopes — this is where reimbursable contracts leak.

Supplier qualification and vendor management

Prequalification criteria checklist

Legal and corporate

• Registered entity, ownership structure, ultimate beneficial ownership
• Relevant licences and registrations, current and in the correct categories
• Financial statements for the last three years; current ratio, gearing, and whether the order value is proportionate to their turnover
• Litigation and arbitration history
• Sanctions, denied party and adverse media screening
• Anti-bribery and corruption policy and training records

Technical and operational

• Demonstrated experience in the specific product or service scope, not the general category
• Manufacturing facilities: owned, leased or subcontracted; capacity and current loading
• Engineering capability and design authority — do they engineer or assemble?
• Sub-vendor list for critical components, and their control over it
• Reference projects of comparable scale, with contactable references

Quality

• ISO 9001 certification and, more importantly, the scope of that certificate
• Quality manual, inspection and test procedures, NCR and corrective action records
• Welder and NDT personnel qualifications where applicable
• Calibration system and traceability
• Historic weld repair rates, first-pass yield, on-time delivery data

HSE and sustainability

• HSE management system and certification
• Lost time injury and recordable rates for the last three years
• Incident investigation records and demonstrated corrective action
• Environmental permits and waste handling arrangements
• Increasingly: emissions data and ESG reporting capability, which large operators now cascade down the chain

Commercial

• Insurance cover: types, limits, and validity
• Capacity to provide bonds and guarantees
• Warranty terms and their after-sales support footprint in the region

Vendor audits

A desktop questionnaire tells you what a company says about itself. An audit tells you what it does.

• Quality system audit: procedures exist, are current, and are actually followed on the shop floor. Trace one real order end to end through their system.
• Manufacturing capability audit: machine list versus what the scope requires, current shop loading versus your delivery window, calibration status of measuring equipment, materials storage and segregation.
• HSE audit: walk the floor. Housekeeping, PPE compliance, lifting practice and permit systems tell you about management culture faster than any document.
• Sub-vendor audit: for critical items, audit where the critical component actually comes from.

Audit findings should be closed formally with evidence, and the closure verified before award for anything material.

Vendor scorecards

Score consistently, on a small number of things that matter:

Dimension	Weight	What it measures
On-time delivery	30%	Actual delivery against contractual date, per line item
Quality	25%	NCR count and severity, first-pass acceptance, rework
Documentation	15%	MDR completeness and timeliness against the agreed index
Responsiveness	15%	Query turnaround, expediting cooperation, escalation behaviour
HSE	10%	Incidents, compliance during site work
Commercial conduct	5%	Change order behaviour, invoicing accuracy

Publish the scores to the vendors. A scorecard nobody sees changes nothing; a scorecard reviewed in a quarterly business review changes behaviour within two cycles.

Contracts and commercial terms

Pricing structures

Structure	How it works	Best for	Main risk
Lump sum / fixed price	Fixed price for a defined scope	Well-defined, stable scope; standard equipment	Every ambiguity becomes a variation claim; contractor prices contingency you cannot see
Unit rate / remeasurable	Agreed rates applied to measured quantities	Known activity types, uncertain quantities (piping, earthworks, drilling services)	Quantity growth; requires disciplined measurement
Reimbursable / cost-plus	Actual cost plus a fee	Early-stage, undefined or urgent scope	No inherent cost pressure; needs open books and audit rights
Target cost with pain/gain	Agreed target, over- and under-run shared	Complex scopes where alignment matters more than price certainty	Getting the target right; disputes over what counts against it
Frame agreement with call-off	Pre-agreed rates and terms, drawn down as needed	Repeat categories, OPEX spend	Rate drift versus market; scope creep across call-offs

Incoterms® in practice

Incoterms® 2020 allocate cost, risk and obligation between buyer and seller. The rules most commonly used in energy procurement:

• EXW — buyer collects from the seller’s premises and takes on everything from that point, including export clearance. Maximum control, maximum administrative burden.
• FCA — seller delivers, cleared for export, to a named place. Generally preferable to EXW for containerised cargo.
• FOB — seller bears cost and risk until goods are on board the vessel at the named port. Sea and inland waterway only, despite being written on countless air freight POs.
• CFR / CIF — seller pays freight (and, for CIF, minimum insurance) to the destination port, but risk transfers at loading. This split between cost and risk transfer is the most misunderstood point in the entire framework.
• CPT / CIP — the multimodal equivalents of CFR/CIF. CIP under the 2020 revision carries a higher default insurance requirement than CIF.
• DAP / DPU — seller delivers to the named destination place, unloaded (DPU) or ready for unloading (DAP); import clearance remains with the buyer.
• DDP — seller delivers cleared for import with duties paid. Convenient, but you are paying someone else’s margin to manage your customs risk, and they may not manage it well.

Three practical rules: always state the rule, the named place and the Incoterms® version; never use a maritime-only rule for air or multimodal shipments; and remember that the Incoterms® rule does not by itself determine when title passes — that is a matter for the contract terms.

Total landed cost is the number that matters: goods price + freight + insurance + duty and taxes + clearance and handling + inland transport + storage and demurrage risk + financing cost of the payment terms. Bids quoted on different terms must be normalised to this basis before comparison.

Liquidated damages, warranties and guarantees

Liquidated damages for late delivery must be a genuine pre-estimate of loss, capped (commonly a percentage of order value), and tied to a clearly defined milestone. LDs are a remedy, not a schedule recovery tool — a vendor who has hit the LD cap has lost their financial incentive to accelerate, which is exactly when you need them to. Pair LDs with a right to step in, expedite at the vendor’s cost, or terminate.

Performance guarantees cover whether the equipment does what it was sold to do — flow, head, efficiency, emissions, availability. Specify how performance will be demonstrated, under what conditions, who witnesses it, what the tolerance is, and what happens if it falls short: rectification, repeat testing, or liquidated performance damages.

Warranties need attention to four points: duration (and whether it runs from delivery or from start-up, which for equipment stored on site for a year is a material difference), scope (parts only, or parts and labour and access), remedy (repair, replace, or refund), and the extension of warranty on repaired or replaced items.

Bonds and guarantees:

• Advance payment guarantee — protects prepayments, reducing as work progresses
• Performance bond — typically a percentage of contract value, called on default
• Warranty or retention bond — replaces cash retention, freeing the vendor’s working capital
• Parent company guarantee — where the contracting entity is thinly capitalised

Watch for on-demand versus conditional instruments — the difference determines how easily you can actually call them.

Payment terms

Structure milestones so payment follows verified value, not calendar dates: on order, on approval of drawings, on receipt of major materials, on completion of manufacturing, on successful FAT, on delivery, on acceptance of the MDR, and on completion of the warranty period. Withholding a meaningful final payment against MDR acceptance is the single most effective documentation control available — it works better than any number of chasing emails.

Deeper coverage of these structures sits in Engineering, Procurement & Construction Contracts (EPC), EPCIC Contract Drafting and Management, and for the risk transfer side, Energy Insurance and Risk Management.

Common procurement pitfalls, and how to avoid them

Poor scope definition → change orders and cost growth. Prevention: a formal requisition completeness check before RFQ issue. If the datasheet is not approved for enquiry, the enquiry does not go out. Where the scope genuinely cannot be frozen, buy the engineering deliberately as a paid pre-order study rather than absorbing the ambiguity into a fixed price.

Late vendor engagement → schedule slip that cannot be recovered. Prevention: identify long lead items at FEED and commit against a reserved slot or a limited notice to proceed. Track the requisition date, not just the PO date — the delay almost always originates upstream of procurement, and procurement gets blamed for it.

Weak TBE discipline → the wrong technical selection. Prevention: named discipline evaluators, a formal deviation register, technical equalisation priced before the commercial round, and a firewall between technical and commercial submissions. Fix scoring criteria before bids open.

Missing MDR requirements → handover delays and retained payments. Prevention: issue the MDR index with the RFQ, price it, agree a document submission schedule with intermediate milestones, and tie the final payment to acceptance. Review a document sample at 30% manufacturing completion rather than discovering the format problem at the end.

Inadequate expediting → late delivery discovered too late to act. Prevention: risk-rank the PO portfolio and set the expediting intensity accordingly. Extend expediting to sub-vendors for critical items. Require milestone-based reporting rather than percentage-complete narrative, and treat the first missed milestone as the signal, not the third.

Fragmented spend and maverick buying → lost leverage, uncontrolled vendor base. Prevention: spend analysis by category and supplier, catalogue and call-off automation for low-value items, and a delegation of authority matrix that people can actually follow. Maverick buying is usually a symptom of a process that is too slow, not of undisciplined staff — fix the cycle time and much of it disappears.

Single-source dependency discovered during a crisis. Prevention: map single points of failure by category, qualify a second source for critical items before you need one, and hold strategic spares where qualification of an alternative would take longer than the tolerable downtime.

Documentation and inspection accepted at face value. Prevention: verify certificates against the physical item — PMI on critical materials, certificate numbers checked against heat numbers, Ex certificates checked against the actual model and configuration. Counterfeit and mis-certified product exists in every market.

Commissioning and O&M requirements omitted from the PO. Prevention: include vendor commissioning support days, commissioning and two-year operational spares, special tools, and training in the original scope. Buying these afterwards costs several times more and arrives late.
