Siemens to supply equipment for Mayflower Wind offshore project

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

The plant is located approximately 25 miles south of Nantucket, Massachusetts in the United States, in a federal lease area and will have the capacity to produce 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 given Siemens the contract to supply high-voltage electrical equipment for the ESP, including three 275kV/265 MVAr shunt reactors, a 72 kV HV gas-insulated switchgear (GIS), three 275 kV MV GIS systems, an integrated conditioning monitoring system and SCADA and protection systems.

“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. We are looking forward to the cooperation with Siemens, who is a competent and reliable partner.”

Carsten Nielsen, senior VP of renewable energy at Semco Maritime.

“We are proud of the opportunity to bring our expertise in offshore transmission to Mayflower Wind, a project that will lead the way for increasing the share of clean, renewable energy in the U.S. energy mix. 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.”

Beatrix Natter, CEO of the transmission division at Siemens Energy.

The system is specifically designed to greatly reduce the platform’s size and weight, minimize the need for steel usage in construction and thereby make the platform more resource-and cost-effective.
