Numerical analysis of ship-ship interaction by a high-order potential flow code with ship motions

摘要

This work is motivated by the desire to include a rational prediction of the interaction effects between a maneuvering tug-boat and a steadily moving ship within a training simulator facility for tug-boat helmsmen. To this end, we investigate the performance of the high-order boundary element code AE-GIR with respect to robustness and efficiency by comparing numerical calculations with experimental measurements. The test case considered here involves a tug-boat and a tanker, both sailing at the same constant speed, but with different relative positions of the tug-boat. A range of speeds and lateral and longitudinal distances between the mid-points of the two ships is considered. Based on the comparison, we conclude that it is possible to capture the correct trends in the interaction forces to an acceptable accuracy in real time using this method.
