BERTHING OF A LARGE TANKER TO A JETTY

For the design of fenders and dolphins it is essential to have available an adequate method to describe the berthing manoeuvre of a large tanker to a jetty. Such a method should result in a prediction of maximum deflection of and maximum load in the dolphins. Data are presented on the added mass and damping of large tankers in shallow water. These data were obtained from experiments (forced oscillation tests). From these data it appeared that it is not justified to use a constant (time-independent) added mass and damping coefficient. Therefore it is suggested to use the equations of motion according to W.E. Cummins, which employ impulse response functions. Data on these functions are presented for large tankers for different keel clearances, which can be used for practical applications.
