Concrete gravity-based structures for offshore energy
Aker Solutions is a global leader in the design, engineering and delivery of large concrete gravity‑based structures (GBS) for offshore energy developments.
With more than four decades of experience, we deliver safe, durable and cost‑efficient foundation solutions for projects operating in some of the world’s most demanding environments.
Proven applications across offshore energy
Our concrete gravity‑based structures support a wide range of offshore energy developments, from established oil and gas projects to emerging low‑carbon infrastructure:
- Offshore wind foundations (WTG and OSS)
- Oil and gas platforms, LNG terminals and processing facilities
- Carbon capture and storage (CCS) infrastructure
- Offshore electrification hubs and energy islands
Full lifecycle GBS capabilities
We offer efficient end-to-end capabilities to deliver gravity-based structures from concept to operation:
- Concept development and feasibility studies
- Front‑end engineering and design (FEED)
- Structural and geotechnical engineering
- Construction engineering and fabrication planning
- Marine operations, transport and installation engineering
- EPCI project execution
- Life cycle services and decommissioning support
Our integrated teams combine structural, geotechnical, marine and construction expertise to ensure seamless delivery across every project phase.
Supporting the next generation of offshore infrastructure
While our experience is rooted in oil and gas and LNG developments, concrete GBS technology is now enabling a growing range of low‑carbon infrastructure.
Long service life, inherent stability and low operational risk make concrete gravity‑based structures well suited for large‑scale, fixed offshore assets, including:
Concrete GBS foundations for wind turbine generators (WTG) and offshore substations (OSS) can be serially fabricated in port environments, supporting predictable project schedules, scalable production and efficient installation.
Robust, long‑lived structures suitable for offshore CO₂ storage and processing facilities.
Stable platforms capable of supporting complex processing systems with long operational lifetimes.
Concrete GBS structures offer ideal, durable foundations for multi‑purpose offshore energy hubs. These structures provide long design life, exceptional robustness, low seabed penetration and minimal maintenance requirements — making them well suited for modern, large-scale energy systems.
