Aibel wins Wisting topsides FEED — but Equinor's Barents Sea project is still a cost problem looking for a concept

Equinor has handed Aibel a front-end engineering and design (FEED) contract for the topsides of the Wisting production vessel, following a tender restricted to Norwegian suppliers. The scope includes design maturation to a basis for an execution decision, plus an option for engineering, procurement and project management (EPma). Work starts immediately and is scheduled to finish in late 2027, employing roughly 250 people at Aibel's Asker office with support from Haugesund.

That is the announcement. What matters is the calendar arithmetic around it.

Two decision gates, one engineering deadline

The licence — Equinor 42.5% (operator), Aker BP 27.5%, Petoro 20%, INPEX Idemitsu Norge 10% — intends to take a concept selection and progress decision around end-2026, with FID planned for late 2027. Aibel's FEED is due to complete in late 2027. In other words, the engineering package that is meant to underwrite the investment case lands at essentially the same moment as the investment decision itself.

That sequencing is worth pausing on. A conventional project runs concept selection, then FEED, then FID, with meaningful float between each. Wisting as described runs concept selection before the FEED output exists, and then compresses FEED completion into the FID gate itself. The end-2026 gate therefore looks like a coarse architecture decision — host concept, power solution, subsea layout — rather than a commitment. The substantive gate is late 2027, and it is tight.

Equinor's language is not that of a sanctioned project

Trond Bokn, Equinor's SVP for project development, framed the award with unusual candour: the project is at an early stage, "considerable work remains to develop a project that is profitable and feasible," and the partners "will work with the suppliers on improvements to enable the project to be realised."

Three things follow from that wording. First, profitability is not established. Second, supplier cost is explicitly named as the variable to be improved — not reservoir performance, not schedule. Third, the FEED contract is being used as part of the basis for a potential investment decision, which is the normal function of FEED but reads here as a conditional rather than a procedural statement.

Aibel CEO Mads Andersen's comment reinforces that the driver is as much industrial as commercial: he described the contract as important for "maintaining our centres of expertise" after completing major deliveries on the Norwegian Continental Shelf and in European offshore wind. Aibel is buying workload continuity as much as a project.

Why Wisting has been hard to make pay

The difficulty is structural rather than incidental. Wisting is a Barents Sea oil development, and Barents projects carry a combination of characteristics that squeeze economics: long distances, harsh metocean conditions, limited existing infrastructure to tie into, and — for a standalone production vessel — the need to solve power supply, export and logistics from scratch.

Equinor's own breakdown of the investment is instructive: drilling, wells and subsea development account for half of total investment. That has two consequences.

• The topsides, which is what Aibel is engineering, sit in the smaller half of the capital envelope. Winning this FEED is not the same as winning the project's centre of gravity.
• Steel and equipment demand will be spread across two very different supply chains — OCTG, linepipe, subsea structures, manifolds and umbilicals on one side; structural plate, pressure-vessel-quality plate, piping and process equipment for the topsides on the other.

What this means commercially

For Aibel and the Norwegian fabrication chain. The EPma option is the prize; FEED is the entry ticket. Aibel's position on the topsides is now advantaged but not secured, since Equinor has confirmed the module fabrication contract will be awarded later. A single-source FEED followed by a separately competed fabrication package is a familiar pattern, and it is designed to keep cost pressure on.

For steel suppliers. This award generates almost no steel demand. Engineering-led FEED consumes drawings, not tonnes. The relevant window is the fabrication award — on the reported schedule, not before late 2027, and plausibly later. Order books for a construction window in the late 2020s would be filled from roughly 2027–2029 (analysis, not reported fact). Equinor has not named a fabrication yard, so it is not yet determinable whether Norwegian, other Nordic, European or Asian yards capture the plate and structural demand.

For the 30-year operating horizon. Equinor cites a 30-year operating period. Long design life implies higher-grade and corrosion-resistant specifications, plus a three-decade maintenance and spares stream — a slow but durable demand signal, contingent entirely on FID.

The risk the headline conceals

A FEED award is not a construction commitment. In projects under cost pressure, FEED can precede re-scoping, deferral or cancellation, and the fact that this contract exists to establish whether the project is "profitable and feasible" is precisely the scenario in which that happens. Readers should treat the Aibel award as evidence of engineering capacity being reserved to solve a commercial problem, not as evidence the problem has been solved. The decision to watch is not this one; it is the late-2027 FID, and before that the end-2026 concept gate that will reveal which production concept — and which power solution — the partners believe can clear the cost hurdle.

Gaps worth closing against primary sources: contract value, number of bidders, field reserves and plateau rate, water depth and tie-back distance, power supply concept, and absolute capex. None are disclosed in the available reporting.
