A trim corrected innage c. An uncorrected innage d. A trim corrected ullage 5. 4.49 In what circumstances will a wedge condition exist? a. If liquid covers the bottom of the tank. b.

Yes b. No 7. 4.04 Can a free water volume be calculated using a wedge formula, if the water does not touch the forward bulkhead. a. Yes b. No 8. 4.50 When non-liquid material covers the whole bottom of a tank, trim corrections are applicable. a. True b. False 9. 4.34 In API MPMS Chapter 17.2 are there any guidelines for vessel inspection in adverse weather? a. Yes b. No 10. 4.01 If the vessel incurs an in transit loss of product and an in transit gain in water, what action should be taken? a. Obtain samples of the free water b.

Report to the person in charge on the vessel d. Start taking temperatures 12. 4.32 If a vessel is being gauged in a swell the minimum number of dips per tank should be? a. One b. As many as necessary until two identical readings are obtained c. Three and then averaged d. At least five, taken over the period of the motion, recorded and then averaged 13. 4.22 The On Board Quantity (OBQ) measured at a loading port will usually be greater than the remaining on board (ROB) measured at the previous discharge port. a. True b. False 14. 4.43 What is meant by the term trimmed by the stern? a. The aft draft reading is greater that the forward draft reading b. The forward draft reading is greater than the aft draft reading. c. The ship has water in the aft peak tank. d. Trim corrections will always be subtracted from the measured gauge 15. 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 d. The areas can be ignored 16. 4.76 Which of the following is most likely to require a tankentry inspection? a. Petrochemicals b. Jet fuel c. Diesel fuel d. Heavy fuel oil 17. 4.48 The trim of a vessel will have no effect on the detection of free water. a. True b. False 18. 4.63 What is a wall wash test? a. A procedure involving high pressure automated washing of the walls of a tank to remove any cargo residue b. The activity of rinsing the wall of a tank with a solvent and obtaining a sample of the previous product(s) to determine compatibility with the product to be loaded c. A procedure in which a tank is washed with caustic solution to remove surface build-up d. Answers a., b. and c. are all wrong 19. 4.77 Why should you never break blisters in a tank coating and never disturb piles of debris on a tank floor when performing a tank entry inspection? a. The tank atmosphere may be adversely affected b. The Inspector may come into contact with potentially dangerous, unknown material c. It is the responsibility of vessels personnel to remove debris and prepare the tank surface before the tank is loaded d. Answers a., b. and c. are all correct 20. 4.58 Using the Imperial system of measurement; how far apart are draft mark numbers? a. 12 inches b. 9 inches c. 6 inches d. 3 inches 21. 4.46 What is the most accurate way of measuring a vessel s list? a.

By comparing the fore and aft drafts 22. 4.20 Is it correct to apply a wedge calculation to an OBQ/ROB volume if the material is touching all four tank bulkheads ? a. No b. Yes 23. 4.79 What should a sea valve be sealed to? a. The pump-man s wheel wrench b. An adjacent static object such as another valve or railing c. The main body of the sea valve d.
