Manoeuvring models. Sub report 3. KCS. 6 DOF manoeuvring model with full roll coupling

This report discusses the tests that have been carried out with the benchmark KCS ship model in the towing tank in the first half of 2017. An extensive open water manoeuvring program has been carried out, including the steering of the roll motion with the newly developed roll engine. The KCS is particularly affected by the roll motion due to its stern shape. This was also confirmed during a parametric roll test program. The 6 DOF manoeuvring model has been extended with additional terms to cope with the roll steering. The ship manoeuvring simulator has been accordingly adapted and fast time simulations have been carried out. These simulations revealed once more that additional tuning is needed to obtain a realistic manoeuvring behaviour.
