The lasts months Amasus’ RoRo heavy cargo deck carriers Rotra Mare and Rotra Vente went through huge modification. These modifications made it possible for both vessels to transport the next generations windmill equipment.

Both vessels have undergone modifications at the Holland Shipyards Group facilities in Delfzijl and Hardinxveld-Giessendam.

Rotra Vente

The for the Rotra Vente so characteristic cover has been removed and she was equipped with sponsons around the hull in order to increase her beam for more deck space and stability for sailing with the future generations of wind turbines.

Also her bow opening and Ro/Ro ramp have been modified, this to allow smooth loading and discharging operations for the heaviest windmill equipment.

Rotra Mare

By this modification the length of the Rotra Mare is extended by 11.6 meters. Before the vessel was cut in two pieces, the bow had to be dismantled and placed on deck of the after ship to avoid any stability issues. After the vessel was split into two separate parts the brand new-built section by Niestern-Sander was adapted to the after ship. Next step was connecting the fore ship, whereby the dock had to be lowered. Last but not least the bow had to be lifted and placed back in original position. By this final lift the Rotra Mare was back in original shape.

Both vessels successfully completed their first voyages in their new shape. Rotra Vente delivered nacelles to Rotterdam while Rotra Mare arrived in port of Rotterdam with a full cargo of windmill parts loaded on deck and on the gantries. Windmill parts are destined for a next generation wind farm in front of the Dutch west coast.

And to top it off they passed each other in Rotterdam!
