Prediction of the Effects of Fast Passing Vessels on Moored Vessels

Abstract

An analysis method to determine the behaviour of a moored ship due to wash waves created by a passing fast vessel has been developed. The method can be used for quantitative assessment of the motions of the moored vessels due to wash waves. In this paper a short review of the main elements of the computational method is given and comparisons made with results of model tests carried out at MARIN with the concept of a fast passenger ferry and a captive barge representing a moored vessel. Besides having the possibility to analyse, in the design stage of a fast vessel, the effects on other waterway users, criteria are needed to determine acceptable limits for the motions and accelerations of the moored vessel as caused by the passing vessel. In this paper motion criteria developed based on a comprehensive field study carried out in the Netherlands using the experiences of crew members of moored barges are compared with results of computations of barge motions.
