The offshore wind power installation vessels Saipem 7000 and Seaway Strashnov will restart the installation work of the Dogger
Bank B offshore booster station and monopile foundation. The Dogger Bank B offshore wind farm is the second of three 1.2 GW
phases of the 3.6 GW Dogger Bank Wind Farm in the UK, the largest offshore wind farm in the world.
The large offshore installation vessels Saipem 7000 and Seaway Strashnov are expected to arrive at the project site in mid-April
and start construction work. They will be responsible for the installation of the superstructure and monopile foundation of the project’s
offshore booster station (OSS) respectively. In addition, the HEA Leviathan jack-up ship and the Edda Boreas operation and
maintenance ship will also be deployed to the construction site to debug the offshore booster station of the project and monitor
underwater noise during the monopile installation process.
According to the ship’s AIS information data, the installation ship Saipem 7000 was en route from Norway to the Dogger Bank B site
on April 9. The jacket foundation of the booster station of this project was installed last year, and only the superstructure of the booster
station will be installed in this operation. The superstructure of the booster station is currently being transported to the site via the cargo
barge Castoro XI. The anchor tug (AHT) used to tow the cargo barge is the Pacific Discovery.
The installation of the booster station superstructure is expected to last until April 18, after which it will be commissioned by the jack-up
vessel HEA Leviathan (formerly Seajacks Leviathan). Commissioning work will continue until mid-August, and accommodation will be
provided for commissioning personnel during the work.
Seaway’s self-elevating installation vessel Seaway Strashnov plans to arrive at the site to install the monopile foundation after the offshore
booster station of the project is installed. Meanwhile, Subacoustech Environmental will use the operation and maintenance vessel (SOV)
Edda Boreas to conduct underwater noise (UWN) monitoring during the installation of the first five monopiles at Seaway.
