"This is a reminder to owner operators that sometimes it is the most seemingly minor thing such as a
mechanical part or electrical component that can lead to a catastrophe. For example, a nearly 20 year
old bulker was leaving port when its main engine throttle failed. In this case the vessel was able to
drop anchor without incident. The failure occurred because a small drive belt that connected the console throttle lever components to an electrical potentiometer failed. Movement of the throttle causes the
potentiometer to move and creates a variable signal to other controls which manage engine
speed. When the belt failed the control from the engine room console was lost"
