1. 7.53 When inspecting a series of rail tank cars the liquid outage/ullage level must be measured in all cars
    a. True
    b. False
    c.
    d.
2. 7.38 If there is a discrepancy between Reference Gauge Height and Observed Gauge Height when gauging a shore tank what action should be taken?
    a. Adjust the gauge to observed reference height
    b. Ullage the tank
    c. Recheck the gauge, make a note of the difference and inform your supervisor
    d. The difference can be ignored it as long as the ship to shore difference does not exceed 0.5%
3. 7.44 How are free water measurements normally taken?
    a. By the innage method
    b. By the ullage method
    c. By the Heimlich method
    d. Answers a. and b. are correct
4. 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
5. 7.55 What is the purpose of a floating roof correction in a shore tank calculation?
    a. To account for the compression of the liquid due to the roof weight
    b. To account for the volume of liquid displaced as a result of the weight of the roof
    c. To allow for the effect of the roof temperature on the temperature of the product
    d. To allow for the effect of the temperature on the thickness of the roof
6. 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.
7. 7.26 To determine the ullage of the liquid in a tank using an innage tape and bob assembly, what procedure should be followed?
    a. Read the immersion depth of the tape at the reference gauge point and subtract the oil cut reading on the bob
    b. Read the immersion depth of the tape at the reference gauge point and add the oil cut reading on the bob
    c. Subtract the oil cut on the bob from the tank reference gauge height indicated on the tank capacity table
    d. Subtract the oil cut on the bob from the measured tank reference gauge height
8. 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
9. 7.45 When would a check be made for water on the top of a cargo?
    a. If the observed density is less 1000 kg/m3 [observed API gravity greater than 10.0]
    b. If the observed density is greater 1000 kg/m3 [observed API gravity less than 10.0]
    c. It is never necessary to check for the presence of water on top of a cargo
    d. Only for fuel oil cargoes
10. 7.13 What is a tank datum plate?
    a. The position on a tank where the gauge height is noted.
    b. The point marked on the gauge hatch of a tank to indicate the position from which the tank is to be gauged.
    c. The plate on the tank shell that lists the tank general data such as roof weight, height of tank, etc.
    d. A plate placed in the tank and directly under the reference gauge point to provide a fixed contact surface.
11. 7.27 Which industry documents describe the procedures for the gauging of petroleum or petroleum products?
    a. API MPMS Chapter 17.1/EI HM28
    b. API MPMS Chapter 17.9/EI HM49
    c. API MPMS Chapter 3/EI HM4
    d. API MPMS Chapter 1/EI HM0
12. 7.49 When is a provisional gauge or insurance gauge taken prior to the official gauge?
