Korean Register (KR) has awarded an Approval in Principle (AiP) to Marcon, a South Korean marine services company, for a hybrid offshore wind crew transfer vessel (CTV).
The hybrid setup on board comprises an energy storage system (ESS) supplied by Hanwha Aerospace, and linear jet propulsion units, hybrid power conversion devices, generators, and an integrated power and energy management system developed by YusinHR.
The ESS is an immersion unit with a lithium-ion battery and an insulation fluid system which improves insulation strength and the cooling process. The setup also prevents thermal runaway transfer and ensures safety against fire with a smothering extinguishing function.
Meanwhile, the YusinHR propulsion system, with efficiency of up to 70%, will provide the CTV with sufficient power for speeds of up to 25 knots. Marcon said that the vessel is likely to reduce operating time by about 34% and cut carbon dioxide emissions by about 70% compared with traditional internal combustion engine designs.
Commenting on the AiP process, KR’s executive vice president of the R&D Division, said: “It is very meaningful to be part of the first application of an eco-friendly hybrid electric propulsion system for a CTV, and we will continue to provide technical support throughout the vessel’s construction and future launch.”
The vessel is being built at an unnamed Korean shipyard and will be launched next year.
