Ocean Winds, Semco Maritime, OEG, TGS and Deep Wind provide offshore wind project updates

DEME has installed the offshore electrical substation for Ocean Winds’ (OW) Dieppe – Le Tréport wind farm offshore the coast of Normandy, northern France, according to a July 2 news release.

OW, a 50:50 joint venture between EDP Renewables and ENGIE, in partnership with Sumitomo Corp. and Banque des Territoires, commissioned Chantiers de l’Atlantique’s Saint-Nazaire shipyard in western France to build the substation.

Navantia in Spain fabricated the supporting steel jacket structure. DEME’s vessel Gulliver installed the substation at the offshore site.

When operational, the substation will collect electricity generated by the wind farm’s 62 turbines and transfer it to shore via grid connection infrastructure developed by Réseau de Transport d’Électricité (RTE), which operates the French national electricity transmission system.

Iberdrola awards service contracts on Baltic Hub projects

Iberdrola has awarded Semco Maritime two three-year offshore service contracts, with options for extensions, covering above-water scheduled and unscheduled maintenance of electro-mechanical equipment at two offshore substations in the Baltic Sea, according to a July 2 press release.

At present, the Baltic Hub currently comprises the 350-MW Wikinger and 476-MW Baltic Eagle wind farms, close to the island of Rügen, in the German exclusive economic zone of the Baltic Sea.

Balance of plant service works are planned and executed jointly. According to Semco Maritime, there is potential for optimization through the combined project management and deployment of a round-the-clock on-call duty of technicians to reduce operational risks and costs at the two sites.

The project ramp-up phase is underway. Semco Maritime plans to factor in experience from earlier jobs conducted at Wikinger.

OEG to support Inch Cape offshore wind farm construction 

OEG will support the construction phase of the 1.1-GW Inch Cape offshore wind farm in the North Sea, 15 km from the Angus coast of eastern Scotland, until the development becomes operational in 2027, according to a July 3 news release.

More than 100 OEG personnel will participate. Inch Cape will feature up to 72 wind turbines and an offshore substation.

The company will provide topside and marine services including marine coordination, high-voltage and ancillary port services, all managed from the company’s new base in Edinburgh, which offers 24/7 monitoring operations.

It will also operate up to 10 vessels, comprising seven guard vessels on location and three crew transfer vessels to take technicians to and from the wind farm. In addition, OEG will provide metocean sensors and navigation buoys.

TGS snags offshore wind site characterization work

TGS has secured a new offshore wind site characterization contract offshore Norway, including acquisition, imaging and interpretation services, according to a July 2 press release.

The Ramform Vanguard vessel will start shortly of the estimated 25-day program. TGS will concurrently manage imaging and interpretation, and it expects to deliver final data to the client early next year.

Ramform Vanguard is equipped with Ultra-High-Resolution 3D (UHR3D) streamers and integrated geophysical sensors, designed to sample the seismic wavefield at a high spatial and temporal rate, providing HR data of the shallow subsurface targets for the wind farm development.

South Korea offshore wind development cleared to enter EIA phase

Deep Wind Offshore has obtained an electricity business license (EBL) for its 345-MW Admiral Lee offshore wind project in South Korea, according to a July 3 news release.

The award came from the country’s Electricity Regulatory Commission under the Ministry of Trade, Industry and Energy. Deep Wind Offshore said it would apply for further EBLs.

The project, offshore the coast of Yeosu, Jeollanam-do, can now progress into the next development phase.

Admiral Lee is a partnership signed earlier this year between the company and Korea Hydro & Nuclear Power. The EBL followed approval late last year of the Public Water Surface Occupancy and Use Permit.

The environmental impact assessment (EIA) and implementation plan approval process can now proceed, with the co-venturers targeting participation in upcoming REC/PPA auctions.

Following interpretation of high-resolution integrated wind data collected over the site via a floating LiDAR installed in May, there are plans to expand the project area and also the generation capacity to above 1 GW.
