dship Carriers has transported a tidal turbine, main foundation, ballast blocks and further components from Nigg, Scotland, to Nagasaki in Japan.
The total shipment amounted to 1,714 tonnes and included several heavy and oversized units, with weights tipping the scales at 205 tonnes and measurements up to 19.8 m x 16 m x 11.2 m.
Global Renewable Shipbrokers tasked dship Carriers with the transport, on behalf of its client Simec Atlantis Energy.
dship explained that the height of the foundation posed an initial challenge as it exceeded the height of the ship’s holds. dship’s team used CAD software to overcome this and decided to load the tidal turbine, main foundation and ballast blocks under deck of the multipurpose heavy lift vessel Josef.
Captain Hauke Bindemann, supercargo/port captain at dship Carriers, Germany, explained: “For the safe handling and transportation of the cargo, we developed detailed lifting and seafastening plans as well as calculations. The height of the main foundation was 11.19 m, whereas the nominal clear height in the hold is 11.18 m. Due to the individual shape of the hatch cover in the relevant stowage position, it was possible to accommodate the main foundation safely.”
Once the cargoes were stowed and secured with stopper plates and lashing chains, Josef made the 11,000 nautical mile journey to Nagasaki, where the units were discharged onto a barge for further transport to the project site.
