Earlier cellular reefer vessels were constructed with a 'porthole system' for supplying refrigerated air via ducting to containers. Modern vessels are designed to supply only electrical power to integral containers. Select the main reason for this change in design to the vessels and containers from the options given.
A large amount of refrigerant gas was required to operate the 'porthole' system.
The introduction of more powerful diesel engines onto these vessels meant they had sufficient electrical capacity to supply the integral type containers.
Ducted containers had to be transhipped to their final destination after discharge and still required refrigeration for that part of the supply chain
The 'porthole' system design was extremely complex and construction costs were high.
You are to load a cargo of Cyclohexanol to tanks 2, 3 and 4 centre and 2 and 4 wing tanks. The lines to these tanks are all connected at the manifold with flexible hoses and are all capable of being isolated with the exception of 2 centre, which has therefore been designated as the last tank to load. What will you do with the other tanks as they complete loading?
Close only the tank loading valves, so that pressure remains constant around the pipeline system and flexible hoses. Continue to monitor the cargo levels in the finished tanks to ensure that the high-level alarms are not activated as the ship's trim changes.
Close only the corresponding manifold cross-over valves as the tanks finish, so that the pressure in the lines equalises with the pressures in the tanks. Re-check the ullages at the end of loading as they will have changed as the trim of the ship has changed.
Close the tank loading valves, then close the appropriate manifold cross-over valves. After a few minutes, re-open the tank loading valves and leave them like this until cargo operations are completed, to ensure they drain fully. Re-check the ullages at the end of loading and then close the tank loading valves.
Close the appropriate manifold cross-over valves and tank loading valves as each tank finishes. Continue to monitor the cargo levels in the finished tanks to ensure that the valves are not passing.

Many fruit cargoes are carried refrigerated and also under controlled atmosphere (CA) conditions. A situation develops where there is a problem with the main reefer plant that will take several hours to repair but the CA system is still operation. Which of the statements given in the options is the most accurate in these circumstances?
The CA plant could be used to increase the levels of nitrogen in the cargo spaces which will be sufficient to preserve the fruit.
The CA plant could be used to increase the levels of carbon dioxide in the cargo space which will be sufficient to preserve the fruit.
The CA plant will take care of the cargo without the refrigeration plant and therefore there is no further action required and no need for concern.
The CA plant is only an adjunct for the refrigeration plant and therefore there should be concern about the condition of the cargo.

A medium speed diesel engine, operating on heavy oil has suffered repeated exhaust valve failure. Upon inspection damage is noted on the underside of the valve resulting in some cases in holes passing through the valve even though the seating face appears hardly damaged. Which of the given options is the most likely cause of this type of damage?
High temperature corrosion due to high vanadium content in the fuel oil.
Failure of the valve rotators causing distortion of the valve seat.
Incorrect tappet (rocker arm) clearance preventing the valves from closing properly.
Cold temperature corrosion due to high sulphur content in the fuel and incorrect grade of cylinder lubricating oil.
Why is is especially necessary to continue to ventilate the tank and to continuously monitor the atmosphere when working inside a cargo compartment which still contains vegetable oil residues?
For a tank which has contained vegetable oils, if it is continuously ventilated an Enclosed Space Entry Permit is not required. However, for anyone entering the compartment without a permit in place, they must carry an oxygen meter which continuously monitors the atmosphere.
Forced ventilation will create a hard "skin" on the residues, making them safer to stand on. Testing the atmosphere will indicate when this skin has formed, as no further vapours will be released.
Vegetable oils are commonly washed using very hot water. Forced ventilation will make the temperature inside the compartment better to work in. Monitoring the atmosphere will indicate if the humidity is increasing.
Because the decomposing residues continue to release hazardous gases, reducing the levels of oxygen in the tank and making the atmosphere potentially dangerous.
Which of the following can be considered to be two of the main requirements for a paint coating for a cargo space of a General Cargo Vessel?

Certain oil cargoes, such as aviation turbine kerosenes or diesel oils, are specifically noted in ISGOTT as having an inherent hazard that requires ship's staff to monitor tanks containing them when on passage. What is that hazard?
They can absorb oxygen during the refining process and later release it into oxygen deficient atmospheres such as the ullage spaces in cargo tanks; the spaces should be monitored and the atmosphere adjusted if necessary.
They can release acidic elements when the ship is passing through tropical sea areas and the sea temperature rises above 30 degrees Celsius. A sharp odour may give an indication od increased corrosion which will require examination and possible attention after discharge.
Through contact with the tank structure, they can release highly toxic and corrosive matter which will remain in the sludge and can burn human tissue badly during a manual cleaning process. This can be detected by a drop in PTL factor and periodic tests should be made by ship's staff.
Unless containing an inhibitor, they can release toxic vapours if remaining in the ship for in excess of 60 days. If the cargo expands, these vapours may be released onto deck via the P/V valves and become a safety concern if thery enter the ship's ventilation systems.
