- W625357501 abstract "This paper proposes a quantitative assessment method for the safety margin of a ship approaching a berth. When a ship encounters an unexpected situation during a manoeuvre and counters the emergency with a 'crash astern' manoeuvre or other similar action, it will travel a considerable distance before achieving the control intended. The safety of a ship is guaranteed if there are no obstacles within the extra area of water needed to accommodate ship motions arising from her inertia. The larger the sea room lying between the edge of the extra water area and the obstacles, the greater the safety margin and vice versa. Based on the above consideration, the value of a ratio of B to D gives the magnitude safety margin when a ship approaches a berth, where the value of b is the distance between the berth and the edge of the extra water area after applying the emergency 'crash astern' manoeuvre and the value of B is the residual distance to the berth. The safety margin therefore can be evaluated at every moment by calculating the value of this ratio at a different point in time during the approach manoeuvre. The paper also proposes the standardised deceleration patterns of approach speed which are capable of maintaining a constant safety margin." @default.
