You have just loaded a cargo of Toluene and are about to clear the lines into the ship. What particular hazard must you be aware of with this product?
It is a carcinogen but has a relatively high odor threshold value. Personnel may not readily detect any vapour that is ejected through the vent risers and should therefore use filter masks while this operation is in progress.
It is a static accumulator and settling time must be allowed before gauging.
It has a relatively high freezing point and additional line blowing will be required to ensure the vessel's lines are completely clear.
It has a relatively low density. Tanks which are close to maximum filling are especially liable to overflow during the line clearing operation unless the flow of blowing medium is strictly controlled.
After clearing lines following the loading of cargoes such as Naphthas, Xylene, Toluene, Benzene, White Spirits and Kerosenes, it is necessary to wait for a specified period before taking manual ullages or samples. Why is this?
These are all "static accumulator" cargoes. As a cargo line is blown, electrostatically charged bubbles enter the tank and rise through the cargo, generating a high voltage at the surface. It is necessary to wait for a specified period of "relaxation time", to allow the charge to disperse, before introducing any potentially conductive object.
These are all cargoes which may form a wax on the surface of the cargo. As a cargo line is blown, bubbles enter the tank and rise through the cargo. If exposed to cold air as they reach the surface, a wax "carpet" may form across the whole tank. It is necessary to wait for a period of "levelling time" before allowing any air to enter the tank and taking any manual ullages or samples.
These are all cargoes with a high vapour pressure. As a cargo line is blown, the pressure in the ullage space above the surface of the cargo increases. It is necessary to wait for a period of "settling time", before opening the tank lids for sampling and gauging.
These are all cargoes considered to have high noxious vapour levels. As a cargo line is blown, the surface inside the tank is severely disturbed, releasing large quantities of these vapours. It is necessary to wait for a period of "adjusting time", before carrying out any open sampling or gauging.
When are ro-ro units most exposed to damage?
When being manoeuvred for stowage or breaking out of stowage
When turning corners
When being driven up or down the vessel’s internal ramps
When being driven up or down the loading ramp
What would be understood by the message "A yacht has capsized in heavy seas"??
The message means the vessel is taking in water.
The message means the yacht has been overturned in heavy seas
The message means the yacht has lost its Captain in heavy seas
The message means the vessel is experiencing heavy seas and may need assistance
Why should all bulk cargoes be trimmed and levelled on completion of loading?
To assist in the discharge
To prevent flammable gasses being generated
To reduce the possibilities of the cargo shifting at sea
To reduce the risk of cargo damage on passage

You are mid-way through the discharge of several grades of chemicals. You hear a sudden change in tone on a cargo pump and notice hydraulic oil spraying from a broken oil supply pipe. What will you do?

Activate the hydraulic emergency stop. Notify the Duty officer. Close all manual cargo valves. Prepare for emergency spill response.
