As well as having temperature sensors located in the cargo holds some reefer vessels are also fitted with ethylene sensors. Why is it useful to have information regarding the ethylene content in a reefer vessel cargo hold when carrying fruit cargoes?

The ethylene content must be maintained to help ripen the fruit during the sea voyage.

Some fruit cargoes are sensitive to ethylene and the quality of the cargo can deteriorate as they may over-ripen.

The ethylene content can be used as a guide as to when air change fans need to run.

The ethylene content is beneficial to perishable cargoes in transit so the content needs to be monitored in case the level falls.

Can a ZENER BARRIER be installed in a hazardous area?

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.

Some charters will require a reefer vessel to carry a general cargo, for example paper rolls for the manufacture of fruit cartons, on the return, 'empty' leg of a voyage.

A water heating system with automatic temperature control uses steam as the heating medium and the temperature is controlled by a pneumatically operated valve? What would be an acceptable start up procedure of the system from cold state?

Start with the control valve in manual and use the hand jack to gradually increase the temperature by throttling the steam flow before changing to pneumatic control.

Earlier reefer vessels designed and built for liner trade usually had two or three tween decks approximately 2 to 2.5 metres in height and deep lower holds approximately 4 to 5 metres deep. Modern designs usually incorporate more decks each approximately 2.3 metres in height. What is the main reason for this fundamental design change?

The increased proportion of chilled as opposed to frozen cargoes that are carried.

There is an almost universal use of standard height pallets.

It is easier to construct vessels with shallow decks.

The increased number of container vessels has reduced the tendency to carry general cargo outbound from Europe or North America to Australia and New Zealand on reefer vessels.

Where the sills are mounted below the bulkhead deck

Where the sills of the side scuttles are below the margin line

Where the sills of the side scuttles are less than 500 mm above the deepest load line

Where the height of the side scuttles go through more than two decks

LNG carriers often operate between two fixed ports. Why is there likely to be a significant difference in the amount of LNG onboard arriving at the discharge port compared to the amount onboard departing the loading port?

Part of the cargo is used as ship's fuel in the form of boil off gas.

Inefficient reliquefaction plant operation means only some of the vapours are recovered.

Normal leakage through the cargo containment system leads to loss of cargo.

The vapours are constantly vented to atmosphere.

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

Stop the cargo pump supplied by the broken line. Continue discharge with all other pumps.
