STAND-OFF FORCE ON SHIPS MOORED IN STRONG CURRENT

The design of offshore pile-supported fixed berth structures in fast currents is significantly influenced by a stand-off force which develops on a moored ship and tends to push the ship away from the berth. This stand-off force is caused by the set up of a differential head between the berth side and the open water side of the ship due to the obstruction to the current flow caused by the piles in the fixed berth structure. The paper reports on an investigation of the problem in connection with design studies for the Carajas Project in northern Brazil for mooring ships up to 300,000 DWT in up to 6 knots tidal currents.
