Siemens to Supply High-Voltage Equipment for Mayflower Wind LLC Offshore Project

Siemens has been awarded an order from Danish customer Semco Maritime to provide the main electrical equipment for the electrical service platform (ESP) of the offshore wind project Mayflower Wind LLC (Mayflower Wind). 


The project is located in a federal lease area approximately 25 miles south of Nantucket, Mass., and will have a capacity to generate up to 1.6 GW of renewable energy. Siemens will supply the components for Semco Maritime by 2022. 
Earlier this year, a joint venture between the Danish companies Bladt Industries and Semco Maritime was chosen by end customer Mayflower Wind – a joint venture of Shell & EDP Renewables – to design and construct the electrical service platform of the offshore project Mayflower.

Semco Maritime has now awarded Siemens with the contract for the delivery of the high-voltage electrical equipment for the ESP, including three 275-kV/265 MVAr shunt reactors, a 72-kV HV gas insulated switchgear (GIS), three 275-kV MV GIS systems, integrated conditioning monitoring system and SCADA and protection systems.

The system solution is specifically designed to significantly reduce both the size and weight of the platform, lowering the need for the use of steel in the construction and thus making the platform more resource- and cost-effective.
