Gulliver Installs Courseulles Jacket and Substation Topsides

Supported by an extensive in-house experience and know-how of offshore installation works, Scaldis has expanded its impressive track record with the Courseulles jacket with OSS installation.

In close cooperation with client SDI (DEME), the works were succesfully concluded with topside set-down on 28th of March.

Main operations conducted by HLV Gulliver involved pile cleaning, jacket transport in hooks, jacket installation, ROV survey, levelling, grouting and topside installation.

In order to improve operational efficiency and safety or to overcome technical challenges, several solutions were engineered like a Single point lifting tool, remote barge unmooring and in-hook transport of the jacket.

All offshore operations were executed on DP.

Designed and manufactured in Saint-Nazaire by Atlantique Offshore Energy of Chantiers de l’Atlantique, the electrical substation is the nerve center of the park’s electrical system. 

Weighing 2,100t, 41m long, 29m wide and 17m high, it will centralize the electricity produced by the 64 wind turbines to send it ashore to the electrical substation located in Ranville. .

The electricity produced by the Calvados offshore wind farm will supply electricity equivalent to the domestic consumption of 630,000 people, or 90% of the population of Calvados.
