A recurring problem on power driven vessels is faulty machine control or engine control. Problems often occur during manoeuvres because the control gear is not working properly. Some of these incidents lead to serious damage occurring.
A passenger ship with a variable pitch propeller did not manoeuvre as intended when the propeller did not respond. The probable cause in this case was that hydraulic oil had become contaminated with debris that remained at the bottom of the tanks and pipes due to the movement of the ship on the sea. When this occurs the only remedy is to empty the system, clean the tanks and filters and flush them with fresh oil.
Statistics for smaller ships in domestic traffic show that in the last five years, 27 incidents similar to these have been reported that led to collisions with the quay. Altogether 46 people received minor injuries.
