Question 555 Deck Safety

70% to pass

You are attempting to take a dead ship in tow. All lines have been passed and secured. How should you get underway?

A Order minimum turns until the towing hawser is just clear of the water, then reduce speed to that necessary to keep the line clear of the water.
B If the towline is properly adjusted and weighted you can order slow or dead slow and the towline will act as a spring to absorb the initial shock.
C Gradually apply power until catenary almost breaks the water, but keep the catenary in the water.
D Order minimum turns until the towing hawser is taut and then continue at that speed until towing speed is attained.
AI Explanation

The correct answer is C) Gradually apply power until catenary almost breaks the water, but keep the catenary in the water. This is the correct approach because it allows for a controlled and gradual buildup of tension in the towing hawser. Starting with minimum turns until the hawser is taut (option D) can result in an abrupt shock load, which should be avoided. Keeping the hawser just clear of the water (option A) or allowing the hawser to act as a spring (option B) may not provide enough control over the initial tension. Gradually increasing power while maintaining a slight catenary in the hawser (option C) allows the towing vessel to ease into the towing operation and avoid damage to the towing equipment.
