In this paper, a berth mooring for a vessel at a terminal is evaluated by analytical studies. The passing induced loads and motions are calculated for representative vessels moored for offloading in a river channel.
The channel is modelled as a prismatic geometry. Passing induced loads are calculated using the ROPES software and are interfaced with ANSYS AQWA with which a series of dynamic mooring simulations are conducted for the moored vessel. The passing induced mooring line tensions, fender reactions, and vessel motions, velocities and accelerations at the moored ship's manifold are evaluated for a series of load conditions and mooring designs. The effects of changing some of the passing parameters on the mooring loads and motions are also evaluated and discussed briefly. Finally, the risks associated with damage of a single line are reviewed and the means to mitigate this risk are commented upon.
