  1. Question 1

    If two ships are carrying out an STS transfer while underway, what rudder and engine movements should the former manoeuvring ship undertake?
    • None. Her engine should be stopped and rudder amidships.
    • Her rudder and engine should be used as requested by the constant heading ship.
    • Her rudder and engine should conform as closely as possible to the constant heading ship.
    • The Master of the manoeuvring ship must make such rudder and engine movements as he thinks necessary to maintain the agreed heading and speed.

  2. Question 2

    If two ships are carrying out an STS transfer while underway, who is responsible for keeping a navigational watch?
    • Either ship, as agreed by the two Masters.
    • Neither. Both ships must maintain a full deck watch.
    • Both ships must maintain a full navigational watch.
    • The ship which is using her engine must maintain a full navigational watch.

  3. Question 3

    The «weather threshold» is the point at which the mooring line loads become unacceptable. What is the effect on the weather threshold if the displacement of the discharging ship is increased?
    • Increased displacement has no effect on the weather threshold.
    • The effect of increased displacement depends on many more parameters, and cannot be accurately predicted.
    • The weather threshold is increased in line with the displacement of the discharging ship.
    • The weather threshold is reduced due to the extra wind resistance.

  4. Question 4

    The «weather threshold» is the point at which the mooring line loads become unacceptable. What is the effect on the weather threshold of increasing the number of head and stern lines deployed?
    • Increasing the number of moorings increases the weather threshold.
    • The effect of increased head and stern lines depends on many more parameters, and cannot be accurately predicted.
    • The weather threshold is reduced due to the extra rigidity of the mooring system.
    • Increasing the number of moorings has little or no effect on the weather threshold.

  5. Question 5

    The Berthing Coefficient is used when selecting the fenders to be used in an STS operation. What is the formula used to obtain the Berthing Coefficient?
    • (2 × displacement ship A × displacement ship B)/(displacement ship A + displacement ship B).
    • (2 × displacement ship A × displacement ship B)/(displacement ship A × displacement ship B).
    • (2 × displacement ship A × displacement ship B)/(velocity ship A - velocity ship B).
    • (2 × velocity ship A × velocity ship B)/(displacement ship A + displacement ship B).
