Cwind Pioneer


< 200 kWh

Named the CWind Pioneer to demonstrate its position at the forefront of crew transfer vessel innovation, the vessel was developed in response to an industry-wide push to develop and deploy innovative technologies that reduce CO2 emissions, while cost-effectively servicing windfarms located further offshore. The CWind Pioneer achieves this through a hybrid diesel and battery electric power system which enables the vessel to operate purely on battery power while in harbour or at standby in the windfarm, resulting in a decrease in fuel burn and CO2.
