| 1. 4.61 When taking a draft reading which is in metric units; what is the distance between each number? |
| 2. 4.30 When portable electronic gauging equipment is used on board a marine vessel, which of the following considerations needs to be addressed? |
| 3. 4.53 When should a wedge formula calculation be used on a vessel trimmed by the stern? |
| 4. 4.68 Should a wall wash be performed on a wet tank surface? |
| 5. 4.20 Is it correct to apply a wedge calculation to an OBQ/ROB volume if the material is touching all four tank bulkheads ? |
| 6. 4.23 In what case will non-liquid ROB be considered not to be evenly distributed across the tank bottom? |
| 7. 4.50 When non-liquid material covers the whole bottom of a tank, trim corrections are applicable. |
| 8. 4.89 When calculating a VEF, only the most recent twenty voyages should be used: |
| 9. 4.56 What is freeboard on a vessel? |
| 10. 4.33 If the vessel is at a berth and rolling so that the cargo in the tank is moving more than 3 mm [1/8], the minimum number of gauges to be taken is? |
| 11. 4.85 The best way to prove the liquid/non liquid nature of ROB/OBQ is to have a sample |
| 12. 4.87 Can a partial cargo VEF or compartmental VEF can be established? |
| 13. 4.15 It is important when measuring ROB and OBQ to remember that? |
| 14. 4.35 API MPMS Chapter 17.4/ISO 8697 does not address the issue of pumpability. |
| 15. 4.03 If a vessel is out of trim and product in a tank is touching all four bulkheads, should you use the wedge formula to calculate the volume? |
| 16. 4.10 Once sea valves are sealed by an independent inspector, the vessel staff should not operate those valves during custody transfer without consulting with the inspector. |
| 17. 4.62 Which standard covers pre-loading inspection of vessels tanks? |
| 18. 4.17 It has been determiend that ROB material is non-liquid and can only be measured from one gauge point. In order to calculate the volume of ROB, it should be assumed that the ROB is lying evenly across the bottom of the tank. |
| 19. 4.55 What is the preferred method for preparing composite samples from vessel tanks? |
| 20. 4.65 What should the number of areas in a cargo tank to be wall washed be based upon? |
| 21. 4.46 What is the most accurate way of measuring a vessel s list? |
| 22. 4.05 The preferred device for taking temperatures in a marine custody transfer is? |
| 23. 4.26 What is the amount of material found in a tank prior to loading called? |
| 24. 4.42 What is meant by the term trimmed by the head? |
| 25. 4.51 Which of the following conditions must be present for trim corrections to apply? |
| 26. 4.16 When is an OBQ inspection performed? |
| 27. 4.13 What is the purpose of ballast? |
| 28. 4.28 If the Master refuses to allow manual vessel measurements to be taken in accordance with inspection instructions , what should the inspector do? |
| 29. 4.84 It is acceptable for an inspector to sign Dry Certificates, Vessel Cleanliness certificates showing that cargo tanks are suitable for the intended cargo, ROB certificates with pumpability statements, and pumping logs. |
| 30. 4.66 When carrying out a wall wash test of a vessel s cargo tank a number of discoloured areas on the tank surface are noted. If the discoloured areas are less than 20% of the tank s surface area, can these areas be sampled (wall washed) and included the tank sample? |
