Fuel, Ballast Operations. Test 2 – Online Maritime Tests

If you have taken full bunker, what is important to have in mind?

Be sure that all goosenecks are closed to avoid overflow to deck when heating is put to the tank
Pump out a small quantity from each tank at the first opportunity , to avoid having an overflow to deck when you put heating to the tank
Avoid putting heating to the tanks
Monitor the remote gauges all the time

You are in charge of the bunkering, and the rate of flow is 350 tons an hour, you are bunkering in the night time, and you are bunkering into 6 different tanks at the same time. After a while, you are confused, and feel that you have lost track of the situation. What do you do?

Reducing the rate of flow to gain time
Prepare yourself and the crew for an overflow on deck
Open other tanks to relieve the situation
Stop bunkering, and establish facts, before bunkering is resumed

As a part of the preparation for bunkering, we are to empty the fuel oil overflow tank before the bunkering. Why?

In case of an overfilling.
Check that there are no leaks from valve manifold, into overflow tank
To avoid mixing new and old bunker oil
Check that there are no leaks from bunker tanks, into overflow tank.

To avoid overbunkering and oil spill, it is very important that we keep a close monitoring of the bunkering progress, and this is done by sounding and calculations, the most reliable way is:

The remote gauge system will provide us with the necessary information
A combination of ullage soundings and readings from the remote gauges
Calculate time and flow, to find out how much oil is received
Take ullage soundings in the tanks from deck

Why is it necessary to keep cargo and bunkerlines blanked off while not in use?

To be sure you don't mix cargo
To be sure that air is not coming into the tanks
To avoid unexpected oilspill
To avoid contamination of cargo

Before you close the main gatevalve at the ships bunkering manifold, you should notify:

The deck officer on duty at the receiving vessel
The officer in charge at the barge or the foreman in charge if it is at a shore facility
The bunkeroil company representative
Your engineer at the valve manifold in the engineroom at the receiving vessel

When you are connected up to the barge/shore facility and ready to start, who is giving the order to start pumping?

The engine officer in charge of bunkering on the receiving vessel
The barge captain or shore facility foreman
The receiving vessel's captain
The pumpman on the barge or shore facility

To ensure a safe bunkering operation, and minimize the possibility for overbunkering and oil spill, we need a reliable communication system during the bunkering. How will you act, if your telephone connection goes dead while you are in charge of the bunkering, and the bunkering goes with a rate of 350 tons per hour?

Get hold of walkie-talkies and put them into use
Use a crewmember as a messenger between yourself on the manifold, and the engineer on the valvecontrol in the engine room
Stop the bunkering until safe communications are established
Call the electrician, and get him to repair the telephone while the bunkering goes on
