  1. Question 1

    Code: WHU4qDap During inspection and calibration of a cylinder unit, the liner is found to be worn in a cloverleaf pattern with maximum wear midway between the lubrication points. What action is necessary to rectify the problem?
    • Increase the cylinder oil rate to neutralise the corrosive action of the combustion products or change to a more alkaline cylinder oil.
    • Contact engine maker for advice.
    • Decrease jacket cooling water temperature to avoid heat stress.
    • Reduce the jacket cooling water temperature to avoid thermal stress of the cylinder liner.

  2. Question 2

    Code: WXML Which of the below structures of bulk carriers are considered critical?
    • Upper and lower connection of main side frames.
    • Forecastle deck.
    • Longitudinal deck plating outside hatches.
    • The girders.

  3. Question 3

    Code: QgFPQovV Worn piston rings are allowing a small amount of piston blow-by on a 2-stroke main diesel engine cylinder, but due to the circumstances, it is not possible to stop and do a piston overhaul. What is the correct, temporary action to take?
    • Increase cylinder oil feed rate slightly and monitor the scavenge space drains.
    • Increase the cylinder oil rate to neutralise the corrosive action of the combustion products or change to a more alkaline cylinder oil.
    • Reduce speed.
    • Continue to operate the engine as normal.

  4. Question 4

    Code: zT435nhO What would the results of a TAN test, carried out on lubricating oil samples from a diesel engine, indicate?
    • A measure of the remaining alkalinity in the lubricating oil.
    • A measure of the organic acids in the lubricating oil.
    • A measure of the of organic and inorganic acids in the lubricating oil.
    • I don't know.

  5. Question 5

    Code: rMoPvQEK A transformer, rated at 22 kVA, 440/220 Volts, 60 Hz, is used to step down the voltage for a lighting system. The low tension voltage is to be kept constant at 220 Volts. What load impedance connected to the low-tension side will cause the transformer to be fully loaded?
    • 2,2 Ohms.
    • 22 Ohms.
    • 0,22 Ohms.
    • 220 Ohms.
