The vessel will be delivered in 2017 and allow technicians to be stationed at the offshore projects for up to two weeks. MHI-Vestas will charter the new ship for ten years.
As part of the joint-venture agreement, MHI-Vestas is servicing the Vestas turbines installed at the 165MW Belwind offshore project, 46km off the Belgian coast.
In October, MHI-Vestas also won the contract to supply turbines to the 165MW Nobelwind project, due online in 2018.
Esvagt's 58.5-metre vessel will accommodate 22 technicians, tools and spare turbine parts.
It will act as a floating hotel for the engineers servicing the projects in order to cut down on crew transfer time.
Currently, MHI-Vestas is using a "refitted" Esvagt vessel to carry out maintenance on the Belwind 1 site, but the manufacturer said a larger ship was required.
"The new purpose-built vessel has been designed to provide flexibility for the teams who will be providing operational support for different technology types. We are looking forward to seeing the new vessel in service from 2017," said MHI Vestas senior director Asger Pedersen.
In June, MHI-Vestas manufacturing rival Siemens chartered two Esvagt vessels specifically built to service offshore projects. The 83.7-metre long vessels provide accommodation for up to 40 technicians at the EnBW Baltic 2 and Butendiek offshore projects.
