Our client Deme Offshore was contracted to provide the installation of all WTG components in Triton Knoll offshore wind farm. TWD was requested to provide the motion analysis and all seafastening designs on the jack-up vessel Pacific Osprey.
In order to maximise the usability of workspace on deck without compromising on safety, TWD conducted finite element analysis on the whole vessel, and reinforced the deck and local areas where high compressive or tensile forces were present. Following from the analysis and reinforcement, the team delivered a wide range of seafastening designs, including a cantilevered blade substructure which allowed all blades to be suspended over the aft of the vessel. The design enabled five turbines to be loaded on deck per trip and created more space for the towers, nacelles and lifting tools on deck.
