2. 4.67 When carrying out a wall wash test of a vessel s cargo tank a number of discoloured areas, tank coating breaks and exposed sections on the tank surface are noted. If these areas are greater than 20% of the tank s surface area, what action should be taken?
    a. The areas should be washed and the wall washings included with those from the rest of the tank
    b. The areas should be noted on the inspection report but should not be washed
    c. The areas should be washed and the wall washings from these areas kept in a separate bottle

4. 4.64 What is a wipe test?
    a. The procedure of wiping sample containers to ensure they are clean before being submitted to the laboratory

    c. The ship has water in the forepeak tank.
    d. Trim corrections will always be added to the measured gauge
10. 4.18 Why may multipoint gauging be required when performing an OBQ/ROB survey?
    a. To help determine if a wedge condition exists
    b. To help determine the nature (liquid or non-liquid) and quantity of the OBQ/ROB
