Code: HECE A standard convention for a 4 deck reefer vessel is to designate the decks A to D from upper to lower deck. Decks A and B common as are C and D with a gas tight seal between B and C. Apples are to be carried in decks C and D with bananas in A and B. Which of the options is the best to avoid the risk of crossover of temperature and respiration between the two cargoes?

Create a pressure differential with a higher pressure in decks A and B.

Run the cargo fans intermittently in one of the spaces.

Operate the two spaces at equal pressures as the cargoes are compatible.

Create a pressure differential with a higher pressure in decks C and D.

Code: TLPC A reefer vessel is to load a cargo of plantains and bananas. Due to space restrictions both have to be loaded into a common space. The usual delivery temperature for bananas is about 13 degrees Celsius and for plantains it is 7 degree Celsius. What would be the best delivery temperature for the mixture of these two fruits?

13 °C as plantains are less sensitive to the consequences of a higher delivery temperature.

10 °C as this is the mean temperature of the two cargoes and they would both carry satisfactorily at this temperature.

7 °C as plantains are more sensitive to the higher delivery temperature of the bananas.

Adjust the set point of the delivery temperature to 7 °C for 12 hour periods and 13 °C for the intervening 12 hour periods.

Code: QRDV A situation exists where a cargo of palletised fruit is being loaded to capacity on a conventional reefer vessel. In order to load all of the available cargo it is proposed to break down some of the pallets and place the loose cartons on top of the pallets; there is just enough space to accommodate this below the deckhead. From the options given which is the most suitable action to take?

Accept the plan in order to carry all of the cargo.

Reject the plan as the reduced gap at the top of the stow will restrict the return air flow.

Reject the plan as the charter is to carry only palletised cargo.

Reject the plan as the extra handling will incur greater stevedoring costs.

Code: UDNR Reefer vessels form part of the “cold chain” in the transport of perishable goods from the producer to the consumer. There are times when hatches have to remain open in less than perfect conditions, for example strong winds. There are steps that can be taken however to mitigate the effects of this on cargo that has already been loaded. Which of the options given could be considered to be the most important measure to counter the effect of such conditions?

Cover the stow with a Tenasco (heavy plastic) sheet where possible to protect it from the wind.

Reduce the air delivery temperature.

Refrain from ventilating the cargo with fresh air.

Run the cargo fans continuously during cargo operations.

Code: LJNM A reefer vessel is loading a cargo of fruit alongside in a South African port. During loading another vessel arrives at an adjacent berth to have its cargo discharged after having been towed in following a fire onboard which had resulted in abandonment. What should concern the Master of the reefer vessel most about the situation?

The damaged vessel is unmanned and may not be cared for properly.

The speed of cargo operations may be hindered due to the discharge of cargo from the damaged vessel.

The cargo being discharged from the damaged vessel may be in poor condition and may contaminate the loading vessel’s cargo.

That the cargo may be contaminated by the smell of smoke and the products of combustion from the damaged vessel.

Code: RRXF Prior to loading a reefer cargo it is good practise to carry out an “ice test” of the temperature sensors within the cargo space. Part of the test is to immerse the sensors in a test bucket of known temperature, usually zero degrees Celsius as this is the melting point of ice. Which of the options is correct in relation to preparing the test bucket?

Insulated ice buckets should be filled with ice cubes approximately 2 centimetres square and a small quantity of distilled water to produce an ice-water mixture. The ice cubes should be produced from clean distilled water.

Insulated ice buckets should be filled with ice cubes approximately 2 centimetres square which have been made from clean distilled water.

Insulated ice buckets should be filled with ice produced in the vessel’s low temperature chamber. A hole the exact size of the sensor should be drilled into the ice and the sensor inserted into the hole to give a rapid test process.

Insulated ice buckets should be filled with crushed ice purchased in bulk from a shore supplier.

Code: UFBY Data loggers are a vital part of the temperature control and monitoring system on a reefer vessel. In a situation where the data logger fails several days before the end of the voyage it is still necessary to maintain control of and monitor cargo temperatures. How could an accurate, portable thermometer be used to the best effect, to achieve this, in such a situation?

Use the thermometer to check and control the delivery air temperature by inserting it in the delivery air ducting close to the evaporators.

Use the thermometer to check and control the return air temperature by holding it in the return air space on top of the cargo.

Use the thermometer to check the pulp temperature by entering the cargo space and placing it in the centre of the stow.

Use the thermometer to maintain the delivery air settings as they were prior to the data logged breaking down.

Code: MPHE To correctly interpret the readings on the printout from a reefer vessel’s cargo data logger it is essential to have some knowledge of the location of the temperature sensors. Where would the temperature sensor for the delivery air to a cargo hold be expected to be located?

Just above the cooling coils where the air returns from the cargo space.

In the air flow path from the cooling coils, about 3 metres from the coils.

In the air flow path from the cooling coils, but at the opposite end of the cargo space to the coils.

Use the thermometer to maintain the delivery air settings as they were prior to the data logged breaking down.

Code: OETD On a reefer vessel air is passed over the cooling coils before entering the cargo hatch via trunking to cool the cargo. It is important to ensure that the cooling coils are clear of any material such as plastic sheeting or bags. Why is this so important?

The plastic material may affect condensation forming on the cooling coils.

The plastic sheeting may be picked up by and foul the cooling fans.

The plastic material may block scuppers and bilges.

The plastic may interfere with the air flow over the cooling coils and subsequently the cooling of the cargo.

Code: WDBP Select the option which correctly completes the following statement. A conventional reefer vessel operating with a controlled atmosphere plant must have cargo spaces which:

Are fitted with variable speed fans.

Have the normal bulkhead and deckhead penetrations required for a reefer compartment.

Have a minimum number of deckhead and bulkhead penetrations.

Have a gas tight seal.

Code: NOUO Two conventional reefer vessels are being considered for a charter that involves the transhipment at sea, or at anchor, of a cargo of frozen squid, as weather permits. Both vessels have 4 holds, vessel A has high speed, 10 tonne deck cranes and vessel B has 5 tonne, union purchase derricks. Which of the vessels, if any, would be best suited to this type of operation?

Vessel B would be more suitable as the derricks will give more control of the operation at sea or at anchor.

Vessel A would be more suitable as the greater lift capacity of the cranes would allow bigger pallets to be transhipped.

Neither vessel would be suitable as none of the cargo handling equipment fitted could be used at sea or at anchor.

Vessel A would be more suitable as the high speed cranes would allow the operation to be completed more quickly.

Code: WBBW 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.

It is easier to construct vessels with shallow decks.

There is an almost universal use of standard height pallets.

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.

Code: XJJO Achieving a good air flow through the various cargo compartment of a reefer vessel is a principal design aim of a Naval Architect. Which of the options given represents the optimum cargo space shape?

A narrow tapered space as would be found in a forward lower deck.

A square space as would be found in a midships lower deck.

A flared space that would be found in a forward upper deck.

Code: UFXU When considering how non-containerised perishable cargoes such as bananas and grapes are presented for loading the temperature of the cargo is important. Which one of the statements included in the options is correct?

Grapes are loaded at field temperature while bananas are pre-cooled.

Bananas are loaded at field temperature while grapes are pre-cooled.

Bananas and grapes are both loaded at field temperature.

Bananas and grapes are both loaded pre-cooled.

Code: TAJG Refrigerated cargoes are generally easy to secure for a sea passage when compared to some bulk, timber and project type cargoes. The cargo must be stowed so that it will not shift during the voyage and so that a good air flow can be maintained through the cargo. Which one of the given options is most likely to result in this required outcome and a successful carriage?

The stow is unimportant as it is only the temperature in the hold which determines whether or not the cargo is carried successfully.

A tight uniform stow but with vertical gaps in the cargo for air flow.

A loose uniform stow.

A tight uniform stow which forces air through the cargo.

Code: OOIF Some perishable cargoes which are normally carried refrigerated can also be carried non- refrigerated even on a long sea passage. This requires that the commodity is suitably packed and correctly ventilated during transport. Select the option which correctly completes the following statement. The type of cargo most suited for a sea passage under ventilation only would be:

Strawberries.

Grapes.

Onions.

Pineapples.

Code: FSOS What immediate action should be taken if a ship unexpectedly runs aground and stops?
