Seaway Heavy Lifting provides the expertise required for a complete scope of work (EPCI and T&I*), with the experience and capacity to achieve project goals regardless of size and complexity. We partner our clients at the earliest possible stage, seeking the most economical solution. Our teams work in a spirit of cooperation, exploring the options, identifying potential savings and sharing experience. This approach leads to optimised solutions which, in turn, yield significant cost savings.
EPCI: Engineering, Procurement, Construction and Installation, T&I: Transport & Installation.
Seaway Heavy Lifting offers comprehensive Engineering, Procurement, Construction and Installation (EPCI) services for wind farm foundations for the renewable energy industry worldwide. Following the consolidation of parent company Subsea 7’s renewable energy business into Seaway Heavy Lifting, we now undertake major offshore wind projects on an EPCI basis.
Subsea 7’s EPCI systems and processes apply across our organisation. This reflects their extensive EPCI experience of deepwater Oil & Gas projects valued at up to USD 1 billion plus. This consolidation has brought a total project (design/build/install) orientation to the entire Seaway Heavy Lifting organisation.
In addition, we now offer a full marine service, from transportation and installation of foundation structures to cable installation, wind turbine generator (WTG) installation and overall project management.
Seaway Heavy Lifting has become increasingly active in the renewable energy industry in recent years. We have installed many hundreds of foundations and we draw on our two decades of successful installations for Oil & Gas clients worldwide. We have successfully executed over 150 Oil & Gas installation projects, from the North Sea and Black Sea to the Gulf of Mexico, Barents Sea, Malaysia and offshore India. This expertise is available to renewable energy clients requiring EPCI-based transportation and installation, including single lift solutions for fully assembled WTG structures. As demand for these services increases, our operational spread is expanding internationally, with the establishment of Seaway Heavy Lifting centres in Aberdeen, Glasgow, Paris and Hamburg next to the offices in Cyprus and Zoetermeer.

Monopile and transition piece installation
Seaway Heavy Lifting’s hardware and resources for these tasks include: pile handling equipment, purpose built upending frames, pile driving hammers of up to 2,500 KJ (we own and operate an extensive range of piling hammers), noise mitigation systems and transportation by large crane vessel or cargo barge.
Seaway Heavy Lifting has the capacity to install over 250 WTG foundation jackets annually. The principal transport options are crane vessel or barge.
Wind Turbine Generator (WTG) installation
Seaway Heavy Lifting now offers single lift solutions for fully assembled WTG installations. As always, safety is paramount; our solutions reduce risk by minimising work at height. Productivity levels are very high – one WTG daily (including loading, transport, offshore installation and weather standby).
We expect future projects to include requirements for enhanced workability in demanding environments. Here, we already lead the way with our robust floating equipment - offering high workability than alternative solutions.
Substation jacket installation
Several jacket installation options are available: vertical lift jacket, vertical lift from a submersible barge, lift-off and double hook upending, lift-off/lower into the water/re-rig and upending and the use of launching jackets, enabling our clients to design the most economic jacket.
Substation topside installation
Our capabilities include the 5,000 tonnes lift offered by the DP3 crane vessel Oleg Strashnov, with its large deck area and excellent stability and workability characteristics. We have also responded to growing interest in float-over solutions for topsides. We utilise heavy transport vessels or barges and also offer float-overs of large HVDC topsides. SHL is actively exploring new technologies to further improve largescale float-over operations.
