Semco to Study Offshore Transmission Options

Semco Maritime has been awarded a contract to evaluate high voltage AC versus DC offshore wind transmission.

The study, for undisclosed parties in relation to a confidential offshore wind project, will examine the “breakeven” point for HVDC and HVAC transmission for a large offshore wind farm, Semco said.

Semco will use two parameters in its study.
The first is the size (performance) of the wind farm and the second is the distance to the connection point on land.

The result of the study will include technical design and lifecycle costs for both HVAC and HVDC, such as necessary capital investments as well as operating expenses during the life of the plant.

Semco Maritime engineering and technology director Tommy Flindt said: “We are very proud to have been chosen to carry out this exciting study, as we recognise the increased need for these important assessments in the very early concept phase for large offshore wind farms located far from the coast.

“In light of our 18 plus years of experience in offshore transmission systems, we are convinced that we can deliver this study with the necessary accuracy and thus provide the customer with the inputs needed to enable them to make the right decisions.”
