Semco Maritime has won a study to identify the break-even point of HVDC and HVAC transmission for a massive offshore wind farm.
These days, massive offshore wind turbines are both growing in scale and distance from onshore connections. The transmission system, i.e. the technology used to transmit the generated wind power to the onshore link point, is a key technical feature that is strongly affected by this transition. This subject is the backbone of the study won by Semco Maritime.
Transmission design versus direct current (HVDC) transmission design in two dimensions. The first dimension is the size of the wind farm (power output) and the second dimension is the distance to the onshore connection point. The performance of the analysis would be the technical principles and life-cycle costs of both strategies i.e. capital expenditure and operating expenses for the lifetime of the asset.
Semco Maritime has been part of the offshore wind industry since the early 2000s through engineer-procure-construct (EPC) projects with long-term partners Bladt Industries and ISC Consulting Engineers, as well as offshore engineering studies related to high-voltage transmission, offshore foundations, substation systems, geotechnical assessments and high-voltage sea cable.
“We are very proud to have been selected for this exciting study as we recognize the increased need for performing these crucial evaluations at the very early concept stage of large-scale offshore wind farms located far off the coast.
