Wind Energy – Inter Array Cables
DeepOcean has been awarded a contract for installation support of the inter-array cables on the TPC offshore wind farm phase 2 (TPC-II) offshore Taiwan.
DeepOcean’s scope of work includes the installation of the inter-array cables that connect the wind turbines to the offshore substations, as well as the provision of engineering and project management services.
DeepOcean will work together with Dong Fang Offshore and utilise the chartered, recently enhanced high-specification subsea vessel Orient Adventurer to perform the offshore scope.
The vessel has been upgraded with two new ROVs, an under-deck carousel, and a purpose-built cable lay spread enabling the efficient transport and installation of subsea power cables.
“We look forward to working together with Dong Fang Offshore on this significant project. The project win demonstrates the quality and commitment we bring to the global offshore wind industry, working across Europe, Americas and now Asia-Pacific. Delivering high-quality solutions whilst understanding the local requirements from our regional presence is a key part of our operating model,” says Mitchell Pike, Executive Vice President of DeepOcean’s offshore renewables business.
DeepOcean’s offshore renewables team will manage the project locally, supported by subsea power cable installation experts in Europe. The work will commence immediately and be completed during 2026.
TPC-II is located around 6.5-20 km from the coast of Lukang in Changhua County, ROC (Taiwan) and has a capacity of 295MW. The TPC-II site covers an overall area of 51km², and the water depth is between 37-49 metres.
TPC-II consists of 31 turbines on four-legged jacket foundations, connected through three loops of inter array cables on a 66kV (60Hz) network.
The power is transformed to an offshore substation and transported through three export cables to an onshore substation.
