Why is the cargo boil-off vapour on conventional LNG carriers not normally condensed and returned to the cargo tanks?
The amount boil-off is very low due to good insulation so its not worth the effort.
Since the cargo always has a low pressure and temperature there is no need for cooling.
The cargo temperature is normally too low to be cooled with conventional cooling plants.
Because of the high energy consumption needed to condense and recover the boil off.
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.
What is the most negative side of using a centrifugal cargo pump?
Displacing the liquid by reducing the volume inside the pump.
High purchase and installation cost.
Mechanically displaces the liquid in the pump.
The lack of self priming.
Why may wearing sweat rags slung round your neck when working in the machinery spaces be hazardous?
The rags may cause sweat rash.
The rags may cause you to get too hot and faint.
The rags may be caught by running machinery or power tools.
The rags may be soaked with oil and catch fire.
On a RoRo vessel, what factor(s) determine whether or not a cargo unit will tip over?
The length and width of the cargo unit
The width of the cargo unit
The shape and centre of gravity and securing arrangements of the cargo unit
If you have to carry out hot work close to a smoke detector in the engine room, what precautions should be taken?
Notify Master, Deck officer and engineer in charge.The loop for the smoke detector to be switched off and take normal precautions for hot work.
Notify deck officer in charge that a fire alarm may occur.
No special precautions except for having a watch man and a fire extinguisher available.
Disconnect or cover up the smoke detector.
