number of tanks to be filled


In accordance with Coast Guard Regulations (33 CFR), each pressure gage used in fuel transfer operations must be calibrated to indicate pressure within what percent of the actual pressure?



If you observe any situation which presents a safety or pollution hazard during the fuel transfer operations, which action should you take FIRST?

Shut down the operation.


When pumping fuel between an offshore supply vessel (OSV) and a MODU, there must be direct VHF radio contact between the offshore supply vessel engineer and the __________.

person in charge of the fuel transfer


The temperature of the fuel oil received during bunkering operations is critical in determining the __________.

expansion space to leave in a tank


When you have completed bunkering operations, the hoses should be __________.

drained into drip pans or tanks


The most critical part of the bunkering operations, which can result in an oil spill, is when the __________.

tanks are being topped off


Small oil spills on deck can be prevented from contaminating any waters by __________.

plugging all scuppers and drains


To determine if all requirements of the Declaration of Inspection are met for oil transfer operations just prior to bunkering from a shore side facility, __________.

vessel and facility are jointly and independently inspected by the designated persons in charge


Pollution Prevention Regulations (33 CFR) specify that the person-in-charge of bunkering is responsible for the __________.

communications with terminal operator


When a fuel oil tank is being topped off during bunkering operations, the tank valve should be closed __________.

after the shore pumps are stopped


"Checks prior to transfer" are to be performed by who?

jointly by the persons in charge (PICs) of both the barge's and ship's roles of the bunkering operation.


Generally, topping-off begins at ___% of tank volume, and filling stops at ___% of tank volume.

beings at 90%, stops at 95%


To avoid excessive pressures in the fuel oil filling system during bunkering, you should __________.

You are the chief engineer of a vessel of more than 1600 gross tons on an international voyage. While bunkering lube oil in port, the hose fails and oil is spilled into the harbor. After securing the transfer, how would you proceed?

Set out a boom around the ship to control the spread of the oil.


In what application is a remote valve operator most likely to be located outside the machinery space when the valve itself is located within the machinery space?

A valve located in a fuel oil transfer line.


In what application is an emergency shutdown most likely to be located outside the machinery space when the pump itself is located within the machinery space?

fuel oil transfer pump


Which pump takes fuel oil suction from the double bottom tanks and discharges it to the settling tanks?

fuel oil transfer pump


Your ship is working cargo in port when a hydraulic hose ruptures on the weather deck and oil spills into the harbor. Once the source of the oil spill has been secured, how would you proceed?

Follow the procedures outlined in the vessel's Shipboard Oil Pollution Emergency Plan (SOPEP) manual.


The capacity of a fuel oil transfer pump is 100 gpm. If a fuel oil setting tank measures 6 feet by 6 feet by 12 feet high, how long must the pump run to fill the tank to 11 feet, if the tank presently holds 2 feet of fuel?

24 minutes


Coast Guard Regulations (46 CFR) requires machinery driving the fuel oil transfer and fuel oil service pumps to be fitted with a remote means of stopping that machinery __________.
