Substation design from EPG for Kaskasi offshore wind farm

On the afternoon of Friday, June 4, the steel structure of a substation for an offshore wind farm, built by Energomontaż Północ Gdynia SA (EPG) for a Danish customer, was towed from Gdynia on a barge-pontoon.

The steel structure of the topsides (deck) of the platform with the substation was ordered by Bladt Industries A/S from Denmark and is intended for the Kaskasi offshore wind farm with a total capacity of 342 MW in the German waters of the North Sea.

The structure built by EPG will be delivered, on board a heavy-lift barge pontoon on the tow of the vessel FFS Amaranth to Alborga, Denmark, where it is expected to arrive on Monday afternoon, and where Bladt Industries, together with subcontractors (mainly Semco Maritime), will equip and carry out finishing work and testing before installation,

The selection of Energomontaż-Północ Gdynia (EPG) by Bladt Industries as a subcontractor to carry out the prefabrication of the topsides of the offshore substation (including sea stacking on a barge-pontoon) was announced in August 2020. Fabrication of the steel structure of the substation decks had already started in July last year.

Bladt is the main contracting company for the offshore substation construction, including the transition element and the large mono-pile to form the foundation/base of the substation.
The company is also to supply 38 monopiles and transition pieces for the foundations of the wind turbines.

The Kaskasi offshore wind farm will consist of 38 Gamesa SG 8.0-167 DD Flex turbines, each with a capacity of approximately 9 MW.

Installation of the Kaskasi offshore wind farm is expected to begin in autumn 2021, approximately 35km north of Heligoland Island, with commissioning scheduled for summer 2022 (as of August 2020). Its developer and operator is RWE.
