During loading operations on conventional reefer vessels steel sheets are sometimes placed in the hatch square to avoid damage to the gratings in the square. Select, from the options given, the likely consequence of leaving the steel plates in the hatch square.

Steel has a different heat capacity to the cargo and may cause unexpected results from cooling the cargo during passage.

The stevedores will claim against the vessel for removing the steel plates.

The steel plates may overload the gratings if they are left in place with cargo on top.

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.

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.
