Siemens Gamesa is to service the 32 Senvion turbines operating at the 200MW Trianel Windpark Borkum 2 offshore wind farm in the German North Sea.
Installation of the 6.33MW machines was completed in May and the wind farm, which is also known as Borkum West 2.2, has been fully operational since early July.
Siemens Gamesa said maintenance will start on 1 August and covers full scope service for five years. There are also fixed extension options included in the deal.
The operational base for the service campaigns will be Borkum island.
It is the first time Siemens Gamesa has won an offshore service contract for a wind park equipped by another manufacturer and the first time the company will start servicing Senvion offshore turbines since the acquisition of the latter's onshore service business in Europe and its intellectual property in January 2020.
Trianel Windkraftwerk Borkum 2 technical managing director Irina Lucke said: “We are pleased to have Siemens Gamesa at our side, an experienced and reliable partner for the servicing and maintenance of the 32 wind turbines.
“With the full commissioning we have successfully completed the construction phase of the offshore wind park.
“Now the focus is on the resilient and trouble-free operation of the turbines.”
Siemens Gamesa chief executive of the service business unit in North Europe and Middle East Paulina Hobbs said: “I am thrilled to be including this contract in the service portfolio of Siemens Gamesa Renewable Energy in Germany.
“This is a step into the future for us, where servicing other brands’ offshore turbines will become as much business as usual for us as servicing our own.
“We want to show the market we are an offshore service market leader - despite who is the manufacturer.”
Borkum West 2.2 is owned by EWE (37.5%), a joint venture of the power utility of the city of Zurich (24.51%) and Trianel and 17 German municipal utilities (37.99%).
