The system permits vapour recovery via a collection manifold which may be connected to a shore reception facility.

PV valves are fitted to limit the pressure or vacuum within the tank; the PV valves shall be capable of being isolated or by-passed; the system shall be supplemented by pressure sensors within the cargo tank.

The system is fitted to a tank used for cargoes having a flash point not exceeding 60 degrees Celsius and is fitted with a device to prevent the passage of flame into the cargo tank.

Some ships generate electrical power at 440 Volts, but then step up this voltage to supply specific electrical equipment. One common example, may be to feed a large bow thruster. Why is this done?

A large bow thruster will draw very large currents at low voltage. Being typically remote from the generator, significant voltage drops would occur at low voltage.

The shipyard could not purchase High Voltage generating plant at the time of manufacture, so they used what was available at the time.

Manufacturers can supply High Voltage bow thrusters at less cost, and the power factor is improved.

The overall ship's electrical load does not justify High Voltage generating plant. This method allows more power to be delivered to the bow thruster at low running cost.

A positive temperature coefficient thermistor will typically have

Variable reliability

Inaccurate measurement

Relatively linear characteristic

Relatively non linear characteristic

The position of the ship is found by taking a series of bearings using a magnetic compass. How should an error of 5 degrees WEST be applied to the compass bearings?

The same error applies to all bearings and therefore it can be ignored

Add the 5 degrees to the bearings

Subtract 5 degrees to the bearings

The error should be "High" or "Low" and therefore more information is required.

Which of the given options can be considered to be the most important physical property of a liquefied gas?

Its unsaturated vapour density.

Its saturated vapour pressure/temperature relationship.

Its latent heat.

Its molecular structure.

An OBO or O/O carrier, due to the movement of liquid in a cargo hold during rough weather, the possibility of liquid entering the inert gas piping is great. To avoid this U-bends are sometimes fitted on the line emerging from the hatch coaming. These bends generally have a drain cock at the bottom. These cocks should be:

Opened and checked every day irrespective of the weather?

Opened after rough weather or before loading/discharging or transferring cargo to check for liquid accumulation and contents drained into a drip pan.

Never opened?

Left open during rough weather to prevent liquid being trapped in the U-bend and blocking the line?

Which special regulations cover transportation of solid Bulk cargoes?

The cargo securing manual

Classification Society Rules

The timber deck cargo code published by IMO

Some centrifugal cargo oil pumps are designed with an automatic stripping system, which allows the cargo oil tank to fully discharge its contents. By what principle does such a stripping system operate?

On the basis that, if cargo vapour can be stopped from entering the cargo pump suction inlet, the flow will continue without cavitation.

By automatically reducing the rate at which oil cargo enters the cargo pump, such that any vapour lifted along with the liquid does not cause a loss of suction.

By the optimum size and positioning of the suction inlet that feeds the automatic stripping system, which ensures that the cargo oil tank is discharged to the maximum possible extent.

On the principle that if the suction is fitted low enough in the cargo oil tank and a specified minimum trim is maintained, suction will be available until the tank is completely discharged.

Which of the following statements will direct a fire-fighting team to the source of fire?

Fire in the accommodation

Fire on deck

Fire in No. 3 cargo hold, port side, forward

Fire in the engine room

Inert gas drawn from an in-line unit in the main or auxiliary boiler exhaust cannot normally be used in a chemical tanker carrying high-spec products. Why is this?

Because MARPOL severely restricts the cleaning to sea of tanks that have been inerted in this way, unless additional prewashing has first been carried out. This results in the generation of slops which reduce cargo carrying capacity and incurs disposal costs.

Because the gas drawn from such a source cannot be guaranteed to be below the Lower Explosive Limit.

Because the levels of hydrocarbons and suspended soot particles will have a significant negative impact on cargo quality and tank cleanliness.

Because connection between boiler exhaust systems and cargo containment arrangements is forbidden under the IBC Code.
