Engineering that solves challenges

Reduce risk offshore and save time with front end engineering design studies.

In offshore energy, the best outcomes are driven by early identification and management of risk and cost, well before mobilisation begins. At MDL, we know that insight and a clear plan - built through front end engineering design studies (FEED) - are the foundations of safer, smarter operations.

Whether adapting a vessel for deepwater, enabling cable repair or repurposing assets for flexlay, FEED studies help project teams make more informed decisions, reduce risk and unlock efficiency - transforming an idea into a methodology, and a methodology into a viable campaign.

Why FEED matters

FEED studies are strategic tools, delivering far more than routine technical assessments and enabling informed decision-making to:

• Validate concepts before committing to equipment selection or manufacturing

• Identify risks early and reduce exposure

• Optimise deck layouts, equipment selection and handling methodology

• Ensure vessel compatibility and regulatory compliance

• Build a robust business case for investment

These studies turn uncertainty into clarity and that’s where MDL’s engineering instinct shines. Our team doesn’t just analyse ideas, we shape them into executable operations because we combine design, equipment expertise and offshore experience under one roof.

MDL has delivered numerous FEED studies for flex-lay and retrieval scopes in some of the world’s most challenging basins. Our engineers work alongside vessel owners, flexible product manufacturers and engineering teams, ensuring every recommendation is practical and addresses their individual and varying needs.

MDL’s inherent collaborative approach means each study we carry out is tailored and grounded in operational reality – reflecting our One Team ethos. The following examples illustrate our FEED capability:

Repurposing an AHTS for flexlay operations

The study assessed the conversion of an anchor handling vessel for flexlay installation scopes, evaluating deck layout options, structural considerations and installation methodology. The FEED confirmed that flexlay capability could be achieved through targeted integration of handling equipment. The approach provided a practical and cost-effective route to execution by repurposing an existing asset rather than committing to a newbuild solution.

Expanding Jones Act vessel's multi-lay capability:

MDL delivered an early-stage engineering and technical specification study to support a client’s expansion into pipelay operations using its Jones Act compliant vessel. The FEED-led scope assessed how a modular Portable Vertical Lay Ramp (PVLR) could be integrated to enable installation and recovery of both flexible and rigid products.

The study defined system configuration, handling methodology and operability across stern and moonpool deployment scenarios, alongside integration with existing lay equipment. By addressing operability, interfaces and compliance requirements at the FEED stage, the study enabled informed decision-making and reduced technical risk ahead of detailed design and manufacture.

Relocation of SURF using local tonnage:

Early-stage engineering and feasibility support was provided for a SURF relocation project offshore Brazil, involving the recovery and reinstallation of flowlines and installation of a new umbilical. The FEED study defined a modular lay spread and handling methodology aligned with vessel and deck constraints.

By optimising deck layout, equipment integration and operational sequencing at the early planning stage, the project was able to proceed without reliance on purpose-built installation vessels, reducing mobilisation complexity and execution risk.

Adapting a barge for cable repair:

To support future subsea cable repair campaigns in the Middle East, a FEED study was undertaken to assess the feasibility of converting a barge for repair operations. Early-stage engineering focused on equipment selection, deck layout and handling methodology within the constraints of the vessel and operating environment.

The study confirmed technical feasibility and defined a clear pathway to vessel enablement, improving readiness for future cable repair campaigns while reducing uncertainty ahead of mobilisation.
