Wilhelmshaven FSRU

Wilhelmshaven II: Fast-tracking continuous HPNG import using the IQuay® F-Class.

Wilhelmshaven II is an offshore LNG import terminal operated by Deutsche Energy Terminal GmbH (DET). The system was planned, approved, and connected to the grid in only two and a half years, surpassing industry standards.

The gas terminal is connected to the grid via ECOnnect's proprietary IQuay F-Class System. It covers approximately 8,5% of Germany's total energy demand, and remains one of Europe's most utilized, critical import terminals, enabled by the ECOnnect technology.

At a glance

Application: Offshore FSRU-based HPNG import terminal.
ECOnnect contribution: IQuay F-Class transfer system.
Delivery inclusions: Engineering, supply, installation, and commissioning.
Collaboration: Delivered as part of a partner ecosystem involving DET, TES, Gasfin and other stakeholders.
Status: In operation.

The Challenge

Germany's LNG import buildout required marine infrastructure that could be deployed rapidly, with reduced need for fixed infrastructure construction.

The solution: The IQuay F-Class

‍Subsea flowlines: connects to the onshore grid.
Pipeline End Manifold (PLEM): Interface between risers and subsea flowlines.
Risers: flexible hoses connected to PLEM.
Gas balcony: Permanently installed on the FSRU, interface between ship and risers.

A word from our client

"Wilhelmshaven II combines several technologies unique in Germany and Europe: On the one hand, ECOnnect Energy's flexible pipeline system for direct transfer of natural gas to land without a pipe bridge. This has significantly reduced the impact on the seabed ecosystem. (...)"
