Seaway 7, Subsea 7’s Renewables and Heavy Lifting business unit, has been awarded a contract from Equinor Energy AS for the installation of 11 inner array and two export cables on the Hywind Tampen floating offshore wind farm project, offshore Norway.

The Hywind Tampen project is an 88 MW offshore wind farm comprising 11 wind turbines, each being supported by a floating foundation structure. The field is located between the Snorre (PL089) and Gullfaks (PL050) licenses, to which the windfarm will provide electricity.

Steph McNeill, SVP Subsea 7 Renewables & Heavy Lifting, said:

“We look forward to continuing our long-standing, collaborative working relationship with Equinor and supporting them on their energy transition journey, with the development of their pioneering floating offshore wind farm.”

Hywind Tampen wind farm contracts are subject to final approval of the plan for development and operation (PDO) by Norwegian authorities. The wind farm is scheduled to start production at the end of 2022.



Also Subsea 7 has announced an award by OneSubsea®, the subsea technologies, production and processing systems division of Schlumberger, a front-end engineering design (FEED) study for the subsea umbilicals and flowlines system of the Ormen Lange Field, operated by A/S Norske Shell, in the Norwegian Sea.

A/S Norske Shell awarded OneSubsea an engineering, procurement, construction and installation (EPCI) contract to supply a subsea multiphase compression system. Subsea 7’s scope under this contract includes front-end engineering design (FEED), which will proceed to execution phase in the case of positive FID by A/S Norske Shell and its partners, Petoro, Equinor, INEOS and ExxonMobil. The work will be executed as a Subsea Integration Alliance(1) project.

Subsea 7 has already recognised the value of the engineering studies in its Order Backlog. The value of the execution contract will be recognised after FID, following exercise of the option. Assuming FID is reached, it will be equivalent to a sizeable(2) project award for Subsea 7.

The subsea multiphase compression system provided by OneSubsea will be installed at 850 metres of water depth and consists of two 16-megawatt subsea compression stations tied into existing manifolds and pipelines. Power supply and control will be provided by the Nyhamna onshore gas processing plant, which is located 120km from the subsea location. Once the subsea multiphase compression system is installed, the tieback distance will represent a world record for transmitting variable speed power from shore to seabed.

Monica Th. Bjørkmann, Subsea 7’s Vice President Norway, said:

“This award is an important demonstration of the value Subsea Integration Alliance brings by combining the technologies and capabilities of OneSubsea and Subsea 7 into a seamless integrated offering, resulting in the delivery of optimised solutions, with reduced execution and interface risk. This compression tieback project builds on the Subsea Integration Alliance integrated boosting tieback packages supplied to Taqa Otter in the North Sea and Murphy Dalmatian in the Gulf of Mexico.”

Subsea 7 has announced the award of a sizeable contract for Seaway 7, Subsea 7's Renewables and Heavy Lifting business unit, from Jan de Nul for the Formosa 2 Offshore Wind Farm project in Taiwan.

The contract scope includes the transportation, pre-piling and installation of 47 jacket foundations for wind turbines. Seaway 7 will execute the work in 2020 and 2021 using the heavy lift vessels Seaway Yudin and Seaway Strashnov.

Steph McNeill, SVP Subsea 7 Renewables & Heavy Lifting, said:

"We are pleased to have the opportunity to continue to support the Jan De Nul Group in the development of the Formosa 1 and Formosa 2 wind farms in Taiwan. This contract builds upon our significant capability in the installation of large foundations in the offshore wind industry and increases our experience in the Taiwanese renewable energy sector.”
