For the Veja Mate offshore wind farm project, MV Trina has been contracted to transport transition pieces (TP) from the construction site in Aalborg, Denmark, to Eemshaven, the Netherlands. The wind farm is located in the German North Sea. It consists of 67 wind turbines, each with a capacity of six megawatts and a rotor diameter of 154 metres.
In twelve consecutive voyages, the MV Trina transported 67 transition pieces together with the associated platforms and anode cages. For this long-term order, the type 176 vessel was mobilised at Ostseestaal in Stralsund. All hatch covers and tween decks were unloaded for the 22-metre high cargo. Special grids (grillages) were welded to the floor of the hold to ensure stable and safe positioning of the TP's
