Rotra Vente
Provided byHeinen & Hopman
Our mission is to ensure you the perfect climate indoors, regardless of the weather outside.

HVAC | Conversion of a Container Ship

Rotra Vente is the first of two innovative vessels that are specifically designed for the efficient transportation of wind turbines parts like masts, nacelles (engine rooms) and rotor blades. It’s a conversion project carried out by Holland Shipyards by order of the Concordia Group. The base was an existing container ship’s hull, which is transformed into a ‘special service heavy cargo vessel with ramp’.

Holland Shipyards

Holland Shipyards is known for delivering vessels within extremely short lead times at competitive price levels. The yard is well-equipped with modern and comprehensive facilities, allowing for undertaking new build, repair and conversion projects of small and medium-sized vessels.

Transformation of a container ship

The conversion of the original container ship includes the realization of a movable bow and extendable ramp, allowing for Ro-Ro access. For Siemens, the charterer of the vessel, this way of loading and unloading allows for more cost effective operation, contributing to the aim of cutting the costs of generating offshore wind power.
