Siemens announced that Danish customer Semco Maritime has tapped it to provide the main electrical equipment for the electrical service platform (ESP) for offshore wind project, Mayflower Wind LLC. The 1.6-GW project is located in a federal lease area near Nantucket, Massachusetts. Siemens aims to supply components for Semco Maritime by 2022.

Earlier this year, Mayflower Wind – a joint venture of Shell and EDP Renewables — announced that it had chosen the joint venture between Denmark-based Bladt Industries and Semco Maritime to design and construct the ESP of the project.

Siemens contract includes delivery of 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 was specifically designed to reduce the size and the weight of the platform, lowering the need for the use of steel in the construction, making the platform more resource and cost-effective, according to the companies. All parties are looking forward to the endeavor.

“At Semco Maritime, we have for a number of years created a very strong track record to deliver competitive quality projects in electrical infrastructure for offshore wind,” says Carsten Nielsen, Senior Vice President of Renewable Energy at Semco Maritime.

“The offshore Center of Competence in Denmark did an outstanding job in creating a comprehensive, tailor-made solution for this exciting new project, making the best use of our broad transmission portfolio”, says Beatrix Natter, CEO of the Transmission division at Siemens Energy.
