How Much of an FPSO Can Be Standardized?
FPSOs remain bespoke, but common hulls, module interfaces, equipment specifications and repeatable supply chains are making delivery more standardized.
Floating production, storage and offloading units (FPSOs) have always been among offshore engineering's most heavily customized assets. Water depth, metocean conditions, crude properties, gas-oil ratio, carbon dioxide and hydrogen sulfide content, water-injection capacity, export arrangements, client specifications, local regulations and local-content requirements all affect the design. A large FPSO can take years to move from front-end engineering and procurement through hull construction and topsides integration. Mishandling one critical interface can send both schedule and cost off course.
The usual starting point was a particular field. Its hull, topsides, mooring and process systems were designed around that development, and procurement and construction were set up as a separate project. Engineers drew on lessons from earlier vessels, but in practice each FPSO was still its own engineering job.
Contractors now try to carry more from one project to the next. The hull may come from a common design, while some module layouts and equipment specifications are reused. Contractors also reuse engineering, procurement and construction methods where practical. The process plant is then adapted to the field. The FPSO itself remains bespoke, but less of the work starts from scratch.
Hull Construction Can Start Before Contract Award
Guyana, Brazil and Suriname have advanced a series of large deepwater developments in recent years. The FPSOs for these projects often have similar requirements for water-depth capability, production capacity, storage, mooring and export. No two fields are identical, but a large deepwater FPSO designed to process 220,000–250,000 barrels per day and store about 2 million barrels no longer needs to begin with a blank sheet every time.
SBM Offshore has gone furthest in this direction with its Fast4Ward program. The company uses a newbuild multi-purpose floater (MPF) as a common hull platform, supported by a catalog of reusable topsides modules. In its 2026 half-year report, SBM Offshore said it had ordered 13 Fast4Ward hulls by mid-2026. Eight were already in operation or tied to FPSO projects under construction, and another five were under construction. The company also retained options for further hulls at three yards. Among the five units being built, one was intended for Guyana's Longtail development and two for Brazil's SEAP I and SEAP II projects. The other two had not yet been assigned and were being offered in active tenders.
It used to be unusual to start a hull before the FPSO contract had been secured. With Fast4Ward, SBM Offshore can place hull orders and reserve yard and supplier capacity in line with its project pipeline. When a development is approved, the hull may already be under construction, reducing the time between contract award and delivery.
A Standard Hull, but Bespoke Topsides
MODEC's M350 follows the same idea. FPSO Bacalhau was the first FPSO built on the M350 newbuild hull and achieved first oil in Brazil in October 2025. FPSO Errea Wittu, now under construction for Guyana, also uses the M350. The two units serve different clients and fields, with oil-processing capacities of 220,000 and 250,000 barrels per day respectively, but use the same hull design.
The topsides are a different matter. Fluid properties, gas-handling and reinjection capacity, produced-water treatment, power generation, emissions requirements, mooring and metocean conditions still vary from one development to another. MODEC has also noted that crude oil, natural gas and environmental conditions differ by region, and that every FPSO must still meet project-specific requirements and client standards.
What carries over is mainly the hull platform, module interfaces, equipment specifications, design rules and construction methods. Oil and gas processing, water and gas injection, power generation and mooring still have to be configured for the field. The M350 allows the hull and its interfaces to be set early. It does not remove the need for field-specific process engineering.
Onshore Module Fabrication Is Nothing New
Fabricating FPSO topsides modules onshore and integrating them at a yard is not a recent development. FPSO Cidade de Ilhabela, whose module integration was completed in 2014, had 18 topsides modules. Ten were built at Brazil's Brasa yard, which also carried out hull and topsides integration. The current trend is therefore not simply a move toward building modules onshore.
More of the design basis, module interfaces, equipment specifications and supplier arrangements now carry over from one project to the next. Hulls and topsides modules can be built in parallel at different yards. Contractors can order hulls early, reserve long-lead equipment and secure yard capacity against their project pipelines. Instead of rebuilding the procurement and construction setup for every contract, they can maintain a more regular flow of work across several projects.
None of this makes the engineering easier. Design decisions have to be made earlier, interfaces must be set correctly the first time, and construction schedules at different yards still have to match. A late design freeze shows up later in integration and commissioning.
Several FPSO Projects at Once
Running several FPSO projects at the same time puts different demands on a contractor. It needs enough capital to order hulls early and reserve critical equipment and yard slots. It also has to manage several design and construction programs at once, and carry lessons from operations into later units. SBM Offshore and MODEC have completed many projects and operated them for years. That experience has given them a large body of operating data, their own technical standards and established supplier relationships.
A series of FPSO projects can bring repeat orders to yards and module fabricators. Owners and main contractors are also more likely to stay with suppliers that have already performed well. To win follow-on work, a yard must deliver consistent quality, keep to schedule, maintain complete quality records and work with common interfaces, other yards and a global supply chain. A low price may secure the first order, but it rarely guarantees the next.
Few companies can cover engineering, financing, construction and operations. Hulls, modules and equipment will still be built by suppliers around the world, leaving work for companies throughout the supply chain. Repeat orders, however, usually go to suppliers that can fit into an established program and perform consistently.
FPSOs Will Not Become Assembly-Line Products
Field differences rule out a single universal FPSO design, and these units will not be mass-produced like standard industrial goods. But contractors no longer need to approach every vessel as a first-of-a-kind project. In practice, a common hull and some standard modules can be prepared in advance. The topsides are then designed around the field, while procurement, supplier capacity and yard schedules are planned across several FPSOs.
Completing one FPSO does not show that a contractor can manage several at the same time. Once several units are under way, engineering, procurement, yard construction and commissioning all have to stay coordinated. A delay on one project can disrupt those behind it. Much of SBM Offshore's and MODEC's advantage comes from years of managing several FPSO projects in parallel.
