The increasing height of wind turbines has prompted Amasus Shipping to commission a conversion of its MS Rotra Mare at Holland Shipyards Group. Working with Niestern Sander, Holland Shipyards Group will enable the transport vessel to carry the next generation wind turbines. 

The Rotra Mare is currently 141,6 metres long with a width of 20,6 metres. The vessel’s length will be extended to 152,7 metres. To construct this extension, a new section is being built. The current vessel will be cut in half for this purpose, the bow will float out of the dry dock and the new section will be placed in between. This section will first be adapted to the aft ship in the dry dock, after which the dock will be lowered for the attachment of the foreship.

While the Rotra Mare is under construction, Holland Shipyards Group is also working on the conversion of her sister vessel, the MV Rotra Vente. This conversion includes the installation of new sponsoons on both sides of the vessel to increase the deck width to 23.6 metres. The lifted bow will also be raised to load the next generation of wind turbines.

The Rotra Mare is expected to enter service in January 2022, followed by the Rotra Vente in March 2022.
