Wilhelmshaven - Floating storage regasification unit

The Challenge

To rapidly strengthen Germany’s energy security, a new Floating Storage and Regasification Unit (FSRU) terminal had to be delivered on an accelerated schedule. Located on the North Sea coast, the project required the integration of a permanently moored FSRU vessel, marine jetty infrastructure and an onshore connection to the national gas grid, while coordinating multiple stakeholders under tight regulatory and environmental constraints.

The Solution

Initiated in May 2022 under a framework agreement with ENGIE, Tractebel and IMDC supported the project through successive development phases, from site selection and feasibility reviews to front end engineering design studies.
In October 2023, IMDC (a company of Tractebel) signed an Engineering Consultancy Agreement with FSRU Wilhelmshaven GmbH and has been leading the project as Owner’s Engineer. IMDC’s and Tractebel’s scope covers electrical and instrumentation systems, marine and offshore works, and the interface between the FSRU vessel and onshore infrastructure.

Services provided
• Feasibility review and Light FEED studies
• Owner’s Engineering services
• Electrical & Instrumentation (E&I) engineering support
• Procurement and construction support (documentation, inspections, site supervision, quality control)
• Permit support and environmental monitoring coordination
• Advanced numerical modelling (hydrodynamics, seabed behaviour, underwater noise, navigation risk)
• Offshore surveys and unexploded ordnance (UXO) clearance coordination

The Impact

Developed and constructed in less than three years, the terminal plays a vital role in securing Germany’s energy supply by feeding natural gas into the national grid — equivalent to the annual heating needs of nearly four million households. IMDC’s role as Owner’s Engineer contributed to the successful delivery of this strategic energy infrastructure under fast track conditions and complex stakeholder interfaces.
