Mott MacDonald has acted as technical advisor to GE Energy Financial Services in its hunt for equity finance for the Merkur offshore wind farm project.
The 400MW project is located 50km from the German coast, within the German exclusive economic zone.
Merkur comprises 66 GE Haliade 150-6.0MW wind turbine generators installed on monopiles and transition pieces.
A 12-string inter-array cable grid will connect the turbines to a central offshore substation. At the station, voltage will be increased from 33kV to 115kV.
The electricity will then be connected to the Dorpen-West onshore substation via 320kV export cables, which include around 75km of offshore and 90km onshore ground cables.
Once operational, the wind farm will produce 1,585GWh of electricity per year – enough to power about 500,000 households.
Mott Macdonald provided a technical, environmental and social review for the project to identify completion and operational risks.
“Our review identified a number of technical, schedule and financial obligations and potential risks. These included environmental monitoring responsibilities and technical and schedule constraints to protect marine mammals from underwater noise emitted during pile driving activities,” said Mott MacDonald project director Christos Kolliatsas.
Merkur is scheduled to be commissioned in late 2018.
