Offshore developments – solutions for offshore energy

Lifecycle-led offshore developments, supported from the outset

Every offshore development depends on making the right decisions early, managing risk effectively, and selecting the most appropriate technical approach. We provide specialist products and services, backed by engineering expertise, that help operators make better development choices at the point where they matter most – before cost, risk and complexity are locked in.

From early-stage studies and concept select through to FEED, execution and late‑life planning, our teams support greenfield, brownfield and redevelopment projects across both subsea and surface tree developments. By combining lifecycle understanding and practical engineering experience, we reduce installation and operational risk, improve predictability, and help deliver offshore developments more efficiently and reliably.

Flexible, connected solutions, from seabed-to-surface

Every field is different. Rather than advocating a pre-defined solution, we help operators determine the optimal development pathway for their project – whether that’s a subsea or surface development. Working between seabed and surface, we provide the specialist products, services and engineering expertise that transform development concepts into buildable solutions.

Offshore analysis, concept studies, Pre-FEED and FEED: Engineering and analysis that shape development architecture, support concept selection and define the most appropriate development pathway.

Rig‑installable platform solutions: Minimum facilities platform solutions designed for rig-based installation, eliminating the need for a separate heavy lift vessel, simplifying offshore execution, reducing installation risk, shortening schedules and improving project economics.

Subsea development infrastructure: Specialist products and systems that support subsea field developments, including well access systems, drill centre templates and protective structures, helping enable efficient installation, drilling and long-term field operations.

Mobile production facility conversion: Engineering and specialist products that support the conversion of jack-ups and offshore assets into mobile production facilities, delivering the systems and infrastructure needed for safe, efficient production.

Late-life, redevelopment and repurposing support: Engineering, products and services that support brownfield redevelopment, infrastructure repurposing and asset life extension, helping operators adapt existing facilities for future production, decommissioning and energy transition projects.

Delivering adaptable solutions across global offshore projects

We support offshore developments worldwide, delivering intelligently engineered products and services tailored to local conditions, project requirements and development strategies. From subsea drilling templates in Vietnam designed to support long-term field operations, to the delivery of a freestanding Wellhead Support Structure offshore Malaysia and Angola’s first fully solar-powered offshore platform, our experience spans a wide range of offshore environments and field development challenges.

Whether we’re supporting subsea or surface tree developments, every solution is shaped by local fabrication capability, existing infrastructure constraints, environmental conditions and operator objectives. By combining early-stage insight with proven, flexible solutions to support more efficient and reliable outcomes across the offshore lifecycle.

Early-stage development insight that helps operators define commercially robust development pathways before major investment decisions

Adaptable designs that support regional fabrication, reduce emissions and accelerate delivery

Specialist products and services supporting both subsea and surface tree developments

Single-well through multi-well development solutions adapted for water depth, geology and available infrastructure
