Question asked (391): A vessel berths at two different jetties under the influence of a 1 knot beam current. At the first jetty the ship has an underkeel clearance of 5 times the draught and at the second the underkeel clearance is only 0.5 times the draught. If the current exerted a force of 50 tonnes on the ship at the first jetty, what would be the approximate force exerted at the second if the draught is the same? Selected answer: 75 tonnes Correct answer: 150 tonnes

Question asked (812): What would be the correct understanding of the term "a ship is directionally unstable"? Selected answer: When the rudder is kept amidships, the ship will continue on a straight course Correct answer: The ship requires continual application of the rudder to maintain a steady course. Question asked (1047): What is the disadvantage of using chemicals on an oil-spill on the water?

Selected answer: It is difficult to apply the chemicals if the oil drifts away from the ship's side Correct answer: The chemicals make it difficult to remove the oil from the water Question asked (2027): An Oil tanker experiences large bending moments and therefore the deck scantlings must be maintained within "x" length amidships, where "x" is: Selected answer: Half Length

Selected answer: The Relative Motion display and relative vectors is the only display to use for anti-collision purposes. Correct answer: The collision regulations are based on ship courses through the water. Question asked (2943): What is the "Scantling Draught" of an Oil Tanker with segregated ballast tanks? Selected answer: The minimum draught amidships when in ballast condition Correct answer: The draught for which the structural strength of the ship has been designed

Question asked (3005): Some centrifugal cargo pumps on oil tankers are designed with an automatic stripping system, which allows the cargo tank to fully discharge its contents. By what principle does such a stripping system operate?

Selected answer: By automatically reducing the rate at which oil cargo enters the cargo pump, such that any vapour lifted along with the liquid does not cause a loss of suction.

Correct answer: On the basis that, if cargo vapour can be stopped from entering the cargo pump suction inlet, the flow will continue without cavitation. Question asked (5521):
