While wind farms are promoted as an environmentally-friendly source of renewable energy, offshore farms due to their location often in challenging sea conditions require crew transfer and service vessels that mostly rely on diesel power. The vessels typically have to idle at the wind farms after transporting crews and because of the location of the wind farms the CTVs require to be re-charged offshore or they must still rely on diesel.
An emerging sector is focusing on developing a source of renewable power that can eliminate the emissions from idling vessels, which in the case of the offshore sites account for the majority of CO2 emissions from an operational wind farm. Countries such as the U.K. have also called for the conversion of the support vessels to zero emissions. These new technologies are designed to support battery operations. Read on.
