ABSTRACT
Having as target the basin of the Black Sea, the main objective of the present work is to perform an analysis for some shipping routes between various destinations, taking into account the seakeeping safety criteria. The identification of the navigating conditions was done based on scenarios considering two navigation routes for a 800 TEU container ship. Rough sea situations were considered when extreme conditions can be achieved both in terms of amplitudes and accelerations on the three degrees of freedom (vertical, pitch and roll). The scenarios for the navigation routes include eight points in the Black Sea area (denoted as P1, P2 ... P8). The satisfaction survey of the seakeeping safety criteria is achieved for the period between 03.02.2005-04.02.2005, with three-hour records, when extreme sea state conditions occur. The study concluded that for the ship service speed of 18 knots, the proposed routes have some navigation restrictions, mainly due to the oscillation amplitude roll.
