Technical and commercial bid evaluation for oilfield spares

Topics: oil and gas technical bid evaluation; spares quotation comparison; technical deviation register; oilfield RFQ evaluation.

The bid comparison shows three prices for the same spare. The lowest is highlighted. One offer excludes a required document, another proposes a different model and the third includes everything requested. Calling them three prices for the same thing is already a decision, and it may be wrong.

Technical and commercial bid evaluation works when the two reviews remain distinct but share the same controlled bid record. Engineering resolves suitability and deviations. Procurement compares accepted commercial scope and records the authorised award decision.

Establish the comparison baseline

Freeze the RFQ identifier, revision, item lines, quantity, unit of measure, required document references, delivery destination and commercial assumptions. Give every supplier response its own revision and receipt timestamp. If the purchaser changes a requirement during the enquiry, identify which bids have answered that change.

A bid is not fully defined by its covering quotation. Attachments, deviation lists and clarifications may change the offer. The buyer needs a relationship between them, including whether a clarification supersedes a statement or simply explains it.

JIP33 offers one reference structure for separating procurement requirements and data sheets. It does not make a supplier's offered deviation acceptable. IOGP JIP33 FAQ

Put required information and acceptance decisions in different columns. “Certificate promised” records a supplier statement. “Document requirement satisfied for evaluation” records a reviewer disposition. Combining them invites the buyer to make a technical decision by filling a spreadsheet cell.

Put the three offers on a comparable basis

Illustrative example. An operator requests two approved replacement assemblies under RFQ R-52 revision 2. Prices exclude tax. The example omits tax and currency calculations deliberately; the buyer would need approved treatment for those in a real comparison.

The supplier revision numbers below are independent of the RFQ revision. Each response must explicitly address R-52 revision 2; a supplier's “revision 1” can be its first response to that RFQ. Assume this purchasing process permits the clarification and revised offer described below. In a formal tender, use only the clarification or revision route allowed by its rules.

C's stated comparable value is ₹4,00,000 + ₹12,000 = ₹4,12,000, assuming the technical reviewer confirms its response. A's total is not ₹3,60,000 on the same basis because a required inclusion is unresolved. B cannot become equivalent merely by applying a price adjustment to a different model.

Now A submits revision 2: the required document is included, the line value becomes ₹3,84,000 and freight is ₹15,000. Its comparable value is ₹3,99,000. The arithmetic difference from C is ₹13,000. That is a valid comparison of the stated amounts once acceptability and scope are confirmed. It is not a complete award recommendation: delivery commitments, payment terms and the purchaser's evaluation policy still matter.

Keep A revision 1 in the history, marked superseded for the current comparison. Do not update its old cells and lose the reason the apparent saving changed.

Normalise what can be supported

A commercial worksheet can bring explicit freight, packaging or other included charges onto a consistent basis. It should identify whether an amount is quoted, calculated using an approved rule or still unknown. Foreign-currency comparisons need the agreed exchange-rate source and date. Tax treatment needs the finance team's applicable basis; a buyer should not assume recoverability to improve a bid's ranking.

Delivery also requires a common definition. “Ten weeks” may start at purchase order receipt, drawing approval or another milestone. Record the trigger, destination and qualification. An unconditional date and a conditional duration are not directly comparable until those differences are understood.

For a mixed requisition, evaluate eligibility by line and check any package conditions before splitting the award. A supplier might acceptably quote three spares but offer an unresolved substitute for the fourth. Its quoted discount may depend on winning all four. Keep both the line-level result and that commercial dependency visible; do not apply the package discount to a partial award unless the supplier has confirmed it through the permitted process.

Avoid assigning convenient monetary penalties to unresolved technical deviations. A score can organise an authorised evaluation method, but it cannot replace the underlying engineering disposition. The buyer's role is to make the open question visible and route it to the person empowered to answer.

Clarifications must survive into the order

Maintain a clarification log with the question, supplier response, affected line, bid revision and reviewer decision. Where the supplier changes a price or delivery basis, update the commercial comparison through a new controlled revision. Where engineering accepts a deviation with conditions, those conditions must be visible to the order preparer and subsequent receiving or acceptance process.

The award record should explain which comparison was approved and which unresolved issues, if any, were handled under an authorised exception. A purchase order generated from a previous quotation attachment can undo careful evaluation in one step.

Operator procurement policy governs the required method and authority. Oil India's manuals are an example of purchaser-specific source material; use the policy applicable to the actual transaction. Oil India procurement manuals

Where software earns its place

A shared spreadsheet can work for a small enquiry if revisions, evidence and access are controlled. A sourcing platform adds value when many bids and reviewers make that control difficult. Integration should preserve line identity, approved revision and deviation disposition when the award becomes an ERP order.

If rekeying quotations is a significant part of the work, test extraction on the commercial fields buyers actually use. Retain page references and flag contradictory values. Keep “equivalent offered” as the supplier's statement until engineering records its disposition, and leave missing charges unresolved. The RFQ intake pilot explains how to measure the resulting review effort and errors.

An observable acceptance check is simple: select a compared line and reconstruct its requirement, supplier response, accepted deviations, price basis and award decision. Any missing link is an evaluation-control gap, even if the total adds up.

Summary and next actions

A defensible comparison explains what each supplier is offering and why the accepted offers can be compared. Price becomes useful after the scope and revision are clear; it cannot repair uncertainty about either.

1. Choose one recent enquiry and rebuild the comparison against its final approved RFQ revision.
2. Separate supplier statements, technical dispositions and commercial assumptions.
3. Resolve unknown inclusions and delivery triggers before ranking comparable values.
4. Check that the awarded order carries the exact accepted revision and conditions.

To scope a bid-workflow assessment, use one anonymised RFQ, its quotation revisions and the final award record. The review should identify missing links between the technical disposition, comparable price and order, while leaving supplier selection with the purchasing authority.
