MATERIAL FAILURE :
One of the vessels I have served which was six month old tanker. After discharge engine was given one hour notice. Engine was tried out from engine side and from bridge and control
given to bridge control.Vessel cast off and when an astern kick was required by the bridge, engine did not respond. On investigation found starting air cam broke into pieces.
Vessel made alongside with the help of tugs. Office was informed about the break down. Office responded saying that the spare can be connected from manufacturer only after 15 days. The superintendent requested us to do the possible repair and to sail out. On his helplessness and seeing the commercial aspect we decided to repair cam. By observing all safety precautions, cam was welded and ground to its shape and boxed back. Heat treatment was not possible.
It took 5hrs to complete the above job. Vessel was off hire for 5 hrs.
