材料：

At around 0545 hrs the Cutter PILOT-5 approached the Vessel．The cutter&39;s skipper drew the pilot&39;s attention to the fact that the pilot ladder was hanging free in the air and did not stick to the ship&39;s side surface and he suggested to transfer the ladder more to the midship position．The answer to his suggestion was that it was not him who had to climb the ladder．At that time the vessel weighed the anchor and started her engine．

Half the propeller was emerged from the water．The pilot called the vessel and ordered to stop her engine． Because the gangway was already extended，the skipper decided to approach the vessel from the bow．

The 2nd Officer was standing at the upper platform. of the gangway while the 3rd Officer was standing at the lower platform. in order to secure the pilot．The ladder was correctly lit and the Officers had a radio contact with the bridge．At around 0600 hrs the pilot，assisted by the pilot boat engineer，stepped on the pilot ladder and started to climb up．PILOT-5 turned backwards and its crew was observing the Pilot embarkation．

When the Pilot climbed up to the lower platform. he asked for help．The 3rd Officer extended his hand to him．At that moment the pilots&39; hands slipped off the pilot ladder lines and the pilot fell from a height of 7 metres into the water．
