| Madsen Giersing completed the detailed design of the ship repair facility on Motukea Island in Papua New Guinea. The slipway was designed to accept ships up to 10,000DWT with a length of 110m and a maximum lightweight of 5,300 tonnes. The slipway consists of a 264m long haulway with a slope of 1:15. The wedge car where the ship is positioned during the slipping operation is 110m long and 30m wide. The wedge car is pulled up the haulway with a double drum winch, which when reeved to its maximum capacity can pull 5,600kN. The ship can be moved on land in a transverse direction to the slipway by means of a transfer car, 100m long by 14m wide with a total travel of 100m. A number of 100m long maintenance bays placed off the transfer bays provide working areas for the ships. A dry dock barrier can be placed 100m down the slipway, enabling a dry dock with a maximum depth of water of 4m to be created. The dry dock bulkhead is 32m wide and 6.5m high. A 150m long fit-out berth provides a berthing facility for the ships under repair. The wharf has a maximum water depth of 8.6m at low tide. The wall is constructed from precast concrete panels retained by vertical steel soldier piles. |
