All Moray West Transition Pieces Installed Offshore Scotland

DEME won the contract for the installation of monopile foundations and transition pieces at Moray West in 2022. The company’s scope of work also includes the bolting and grouting of the monopile/transition piece connections.

The TPs were delivered by Lamprell under a contract signed with the project’s developer Ocean Winds in 2022. Under the contract, the company was responsible for the construction of 60 wind turbine TPs and two offshore substation TPs.

The units were placed on top of monopiles delivered by Dajin Heavy Industry and the Navantia Seanergies and Windar Renovables consortium.

According to the latest Notice to Mariners, Cadeler’s jack-up vessel Wind Orca has installed 10 out of 60 Siemens Gamesa’s SG 14-222 DD wind turbines. The vessel is supported by the service offshore vessel (SOV) Norwind Breeze and two crew transfer vessels (CTVs) Fob Swath 3 and Fob Swath 5 .

Supplied with “Power Boost”, each turbine can generate up to 14.7 MW output. The pre-assembly activity of the 60 turbines is being managed by Siemens Gamesa, Siemens Energy’s wind business, who are also manufacturing all the 180 B108 blades for the project at their quayside factory in Hull.

Siemens Gamesa is marshalling all turbine components at Port of Nigg from where the Cadeler heavy lift vessel Wind Orca is undertaking the installations.

The first unit was installed in April and the wind turbine installation campaign is expected to last approximately six to nine months.
