1. 7.56 What action should an inspector take when requested to set a stop gauge? a. Refuse, it s not an inspector s reponsibility b. Follow the company s procedure c. Set the stop gauge and take full responsibility d. Tell the vessel/terminal personnel to set the stop and then check it for accurac 2. 7.29 When using water finding paste in light products, how long should the gauging bar be left in position? a. A minimum of 5 seconds b. A minimum of 10 seconds c. A minimum of 30 seconds d. A minimum of 45 seconds 3. 7.51 If a tank s capacity table is an innage or dip table, what is the preferred method of gauging? a. Side Gauge b. Ullage c. Innage or dip d. Outage 4. 7.25 If a portable measurement unit (PMU) is used, which of the following procedures should be followed to measure free water on a vessel before discharge? a. Rely on the PMU alone for free water level measurement b. Use water-finding paste with a sounding rod/rule or dip tape c. Answers a. and b. are both correct d. Recommend to the terminal that the free water received and measured ashore be applied to the vessel figures 5. 7.21 What is the measured distance from the datum plate or tank bottom to the reference gauge point called? a. The observed reference height b. The innage gauge height c. The reference gauge height d. The ullage gauge height 6. 7.06 What does an outage/ullage measure? a. The distance from the tank datum plate or bottom to the tank reference point. b. The distance from the surface of a liquid in a tank to the reference gauge point of the tank. c. The amount of product transferred out from a tank. d. The level of liquid in a tank measured from the tank bottom to the surface of the liquid. 7. 7.16 An ullage gauge is the same thing as an outage gauge. a. True b. False c. d. 8. 7.35 When gauging a tank by the innage method, a comparison between the observed and reference gauge height is made to ensure which of the following? a. The gauge tape and bob are suspended in a vertical position within the tank. b. The gauge bob is in contact with the tank bottom or datum plate c. The tape has not been lowered too far into the tank d. Answers a., b. and c. are all correct 9. 7.02 What occurs when a shore tank is filled to a level in the critical zone? a. The flexing bottom of a tank is at its highest point b. The tank will overflow if more liquid is added c. The floating roof is no longer resting on its legs d. The floating roof is only partially afloat and the capacity table may be inaccurate 10. 7.43 Which of the following statements regarding reference gauge heights is correct? a. They should be recorded from the calibration tables, before you start the tank gauging b. They should be checked against the observed gauge heights c. They should be included in the inspection report d. Answers a., b. and c. are all correct 11. 7.10 What is innage or dip? a. The distance from the datum plate or the tank bottom to the surface of the product b. The measurement from the tank bottom to reference point c. The cut found on the bob d. The distance from the reference point to surface of the product 12. 7.09 What is the observed gauge height of a tank? a. The distance from the reference gauge point to the bottom of the tank or the datum plate as measured during the gauging operation b. The distance from the reference gauge point to the bottom of the tank or the datum plate as shown on the tank capacity tables c. The distance from the ullage pipe to the liquid level d. Usually written somewhere on the ullage pipe 13. 7.33 The use of non-slotted standpipes is not recommended for custody transfer measurements. a. True b. False c. d. 14. 7.57 When setting a min/max stop gauge an inspector should: a. Make calculations and provide the gauge closest to the requested volume b. Inspector s don t set stop gauges c. Tell the terminal to set the stop and you will check it for accuracy d. Make calculations and provide the gauge closest to the requested volume without exceeding the volume to be transferred 15. 7.12 On a shore tank, what is the term for the distance between the Reference Gauge Point and the Datum Point, as measured at the time of gauging? a. Observed reference point b. Reference gauge height c. Total gauge height d. Observed reference height 16. 7.34 When gauging a terminal storage tank prior to loading a barge, an inspector notes that his observed gauge height does not match the reference gauge height. On gauging the same tank on completion of loading the barge he again observes the same difference in observed and reference gauge heights, such that both opening and closing observed gauge height readings are identical. Can the gauges obtained be used for determining the loaded volume? a. Yes b. No c. d. 17. 7.08 An innage gauge bob is pointed to aid in penetration of tank non-liquid. Where is its zero point? a. Top of the eye b. Bottom of the eye c. Tip of the bob d. Inside of the tape swivel 18. 7.41 According to common industry practice, How often must a gauging tape be checked for accuracy by comparison against a traceable master tape? a. Prior to each use b. Every six months c. Prior to initial use and at least annually d. At least once per week 19. 7.15 An innage (dip) tape and bob may be used to take an outage (ullage) gauge. a. True b. False 20. 7.32 For what reasons may a quantity of free water (water bottoms) be maintained within a shore tank? a. To permit easy determination of the shore tank free water quantity. b. So that a certain percentage of free water can be pumped with each movement in order to aid in S&W blending of cargoes. c. To negate any effect that bottom flexing of the tank bottom would have on tank measured quantities. d. To aid in detection of any product seepage from the tank. ให้ตรวจสอบชื่อนามสกุลว่ากรอกครบหรือไหม่ พร้อมกับตรวจข้อสอบว่าเลือกทำครบทุกข้อหรือไม่ ไม่ครบไม่ตรวจนะครับ
