New offshore projects in the pipeline include seismic surveys for various clients in Africa, subsea installation in support of oil and gas activities off Norway and in the Black Sea, and additional construction work on two large offshore wind farms in the German North Sea and the US East Coast.

DEME Offshore awarded US$1 billion balance of plant project for construction of Coastal Virginia Offshore Wind Farm

DEME Offshore has secured a US$1.1 billion balance of plant (BOP) contract for the construction of the Coastal Virginia Offshore Wind (CVOW) project in a consortium with the Prysmian Group of Italy.

The contract, with a total value amounting to over US$1.9 billion, was awarded by Dominion Energy Virginia, a subsidiary of Dominion Energy. Upon completion in 2026, the CVOW will be the largest offshore wind farm in the United States with a total generating capacity of 2.6 GW.

DEME Offshore’s CVOW BOP contract includes the transport and installation of 176 monopile transition piece foundations, three offshore substations, scour protection and the supply and installation of export and inter-array submarine cable systems. DEME Offshore will oversee the complete offshore installation works for the foundations, substations, infield cables, as well as part of the export cables.

Van Oord secures rock installation contract at Ormen Lange Phase Three in Norway

Van Oord has been awarded a contract related to the Ormen Lange Field operated by Norske Shell. This contract for the specialised seabed interventions services of subsea rock installation (SRI) is a continuation of earlier cooperation between Shell and Van Oord on the Ormen Lange Field.

The Ormen Lange Field is a natural gas field in Norway, located in the Norwegian Sea, situated 120 kilometres northwest of Kristiansund. With depths of the seabed that vary between 850 and 1,100 metres, the natural conditions at the site are considered harsh.

The project scope involves the seabed intervention works consisting of pre-lay structure foundations, pipeline and umbilical route preparation.

Subsea 7 has been awarded a contract by Turkish Petroleum for the Sakarya field development offshore Turkey in the Black Sea.

The contract is awarded to Subsea 7 and Schlumberger as part of a consortium. The integrated project scope of the engineering, procurement, construction, and installation (EPCI) contract will cover the subsurface solutions to onshore production, including completions, subsea production systems (SPS), subsea umbilicals, risers and flowlines (SURF) and an early production facility (EPF).

The scope of work to be executed by Subsea 7 comprises the EPCI of the subsea pipelines and associated equipment to connect the subsea wells in approximately 2,000 metres water depth to the EPF. The project includes the provision and installation of infield flowlines, control umbilicals, tie-in connections, associated subsea equipment, 170 kilometres of gas export pipeline and monoethylene glycol injection pipeline to the EPF.

Project management and engineering has already commenced and will be managed from the Subsea 7 office in Istanbul.

Shearwater GeoServices has commenced work on a new 4D monitor survey for Total E&P Angola.

The survey comprises a two-month wide azimuth towed streamer (WATS) 4D monitor survey in the Louro-Mostarda Development areas of Block 32. Amazon Conqueror will be used for the survey in conjunction with source vessels SW Tasman and SW Cook.

Shearwater has meanwhile been awarded a 3D seismic survey contract for acquisition in South Africa on behalf of an undisclosed client. The survey will acquire over 6,000 square kilometres of 3D seismic data and will be executed by Amazon Warrior.

The South Africa project will last approximately four months.

Boskalis has been awarded an inter-array cable installation contract by Ørsted for the German Borkum Riffgrund Three and Gode Wind Three offshore wind farms. The contract includes the transport, installation and burial of a combined total of 106 inter-array cables.

The project will be executed using the cable-laying vessel Boka Ocean, which was acquired earlier this year.
Project preparations will commence shortly with cable installation activities scheduled for early 2024.

The Borkum Riffgrund Three and Gode Wind Three offshore wind farms will have capacities of 900 MW and 242 MW, respectively. Both wind farms are located off the northern coast of Germany in the North Sea.
