Loss of the ship's own propulsion, electric power, steerage and manoeuvrability could be foreseen and eventually occurred.The main technical sequence of events were a break-down of the forward stern thruster causing a major leakage into the shaft tunnel, a collapse of the watertight integrity of the bulkhead between the shaft tunnel and the engine room, primarily caused by non-effectivecable penetration sealings and some undesirable ...
