| 1. 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. |
| 2. 4.38 What is the Reference Gauge Height of a vessel tank? |
| 3. 4.49 In what circumstances will a wedge condition exist? |
| 4. 4.88 When calculating a VEF which of the following data should be excluded? |
| 5. 4.64 What is a wipe test? |
| 6. 4.09 The term simultaneous ballasting or deballasting means? |
| 7. 4.40 Is the holding of a key meeting prior to an inspection required to comply with Industry Standards |
| 8. 4.02 If the vessel has independently certified wedge tables, they may be used instead of calculating the wedge volume yourself. |
| 9. 4.85 The best way to prove the liquid/non liquid nature of ROB/OBQ is to have a sample |
| 10. 4.54 Typically, four parties receive samples at the loading port when a marine tank vessel is loaded. Three of those parties are (1) the independent inspector, (2) the vessel for delivery to the discharging terminal, (3) The vessel for retain. Who is the fourth party? |
| 11. 4.20 Is it correct to apply a wedge calculation to an OBQ/ROB volume if the material is touching all four tank bulkheads ? |
| 12. 4.28 If the Master refuses to allow manual vessel measurements to be taken in accordance with inspection instructions , what should the inspector do? |
| 13. 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. |
| 14. 4.55 What is the preferred method for preparing composite samples from vessel tanks? |
| 15. 4.81 If a vessel is discharging under closed gauging conditions and the valve adapters on board are not compatible with the inspector s electronic gauging equipment. What action should be taken? |
| 16. 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. |
| 17. 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? |
| 18. 4.23 In what case will non-liquid ROB be considered not to be evenly distributed across the tank bottom? |
| 19. 4.73 It is not necessary to prepare a blank of the wall wash liquid if it is supplied by a certified Laboratory. |
| 20. 4.72 When wall washing a tank, which of the following is correct? |
| 21. 4.65 What should the number of areas in a cargo tank to be wall washed be based upon? |
| 22. 4.80 According to Energy Institute HM28 / HM29 API MPMS Chapter 17.1, what should happen as part of a shore inspection? |
| 23. 4.29 If possible, should you seal a vessel s cargo system sea-valves or any equivalent connection to the ballast system prior to loading? |
| 24. 4.13 What is the purpose of ballast? |
| 25. 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? |
| 26. 4.42 What is meant by the term trimmed by the head? |
| 27. 4.18 Why may multipoint gauging be required when performing an OBQ/ROB survey? |
| 28. 4.57 Using the Imperial system of measurement; what size are draft mark numbers? |
| 29. 4.60 When the metric system is used; what size are draft numbers? |
| 30. 4.41 According to EI HM28 [API 17.1], is the inspector required to be present at a key meeting prior to an inspection? |
