Seajacks Zaratan returns to Akita offshore wind farm

Seajacks Zaratan, a self-elevating platform (SEP) installation vessel, arrived at Akita Port in northern Japan on 15 June 2022 for turbine installation at the Akita offshore wind farm (139 MW) scheduled to begin at the end of this month.

The wind farm is comprised of two sites –
Akita Port (54.6 MW) and Noshiro Port (84 MW) – and is owned by a consortium of 13 companies, including Marubeni Corporation, who is leading the project. Turbine installation is expected to take place from late June to early autumn, likely concluding in October or November. It is expected to take approximately 2 months at each site. Installation will begin in the Noshiro Port site, comprised of 20 turbines, and conclude in Akita Port, comprised of 13 turbines.

Zaratan was initially contracted for a period of 96 days, with turbine installation scheduled to begin in April and conclude in July 2022. In April 2022, the contract was extended through until the end of November 2022, with installation beginning slightly later than originally planned. The project is expected to enter commercial operation by the end of 2022, likely in December.

Zaratan previously installed the 33 monopile foundations at the wind farm (20 monopiles at Noshiro Port and 13 at Akita Port) between May and September of 2021.

Following work in Japan,
Seajacks Zaratan will travel to the west coast of Taiwan to provide transportation services and perform installation of the remaining turbines at Yunlin offshore wind farm (640 MW) in the second quarter of 2023.
