With reference to the bunkering and storage of marine diesel fuel: state the maximum temperature at which diesel fuel oil can be stored.

Diesel fuel oil should generally be stored at a temperature at least 10°C below its closed flash point to minimize fire risk from vapour generation. Signup and view all the answers

With reference to the bunkering and storage of marine diesel fuel: explain why a representative sample of the fuel should be obtained.

A representative sample is obtained to verify the quality and specifications of the delivered fuel against the bunker delivery note (BDN) and charter party requirements. It serves as evidence in case of disputes regarding fuel quality, contamination, or off-specification parameters which could damage machinery or cause non-compliance with environmental regulations (e.g., sulphur content).

With reference to Sewage Treatment Plants: describe the procedure involved in the inspection in part (a).

A typical inspection procedure may include: <ol> <li>Check overall condition, looking for leaks or damage.</li> <li>Verify operation of pumps (e.g., feed, discharge, air blowers).</li> <li>Check fluid levels in different compartments (if visible).</li> <li>Inspect and clean filters (e.g., inlet screen, effluent filters).</li> <li>Test alarms (e.g., high level, system failure).</li> <li>Check disinfectant levels and dosing system operation (for chemical treatment types).</li> <li>Observe effluent quality (visually check for clarity, odour, suspended solids).</li> <li>For biological systems, check aeration patterns and potentially dissolved oxygen levels or sludge condition.</li> </ol> Signup and view all the answers

With reference to Sewage Treatment Plants: explain the reason for fitting a flame gauze to a sewage treatment plant, stating where it would be found.

A flame gauze (or flame screen) is fitted to prevent the transmission of flame into a space containing flammable gases. In an STP, particularly those using biological processes, decomposition can produce flammable gases like methane. The flame gauze would typically be found on vent outlets from tanks or compartments within the STP where such gases could accumulate. Signup and view all the answers

With reference to refrigeration plants, describe the effects of undercharge of refrigerant, stating remedial actions to be taken.

Effects: Reduced cooling capacity, continuous running of the compressor, low suction pressure, low discharge pressure, possible frosting only near the expansion valve, oil return problems. Remedial Action: Locate and repair the leak (using leak detection methods like electronic detectors, soap bubbles, or UV dye), evacuate the system if necessary, and recharge with the correct amount of refrigerant according to manufacturer specifications.

With reference to refrigeration plants, describe the effects of air in the system, stating remedial actions to be taken.

Effects: Increased discharge pressure and temperature, reduced cooling capacity, increased compressor power consumption, potential compressor damage due to high temperatures. Remedial Action: Stop the plant. Allow it to cool and refrigerant to condense. Carefully purge non-condensable gases (air) from the highest point of the condenser or receiver. Monitor pressures during purging. Repeat if necessary. Signup and view all the answers

With reference to refrigeration plants, describe the effects of water or moisture in the system, stating remedial actions to be taken.

Effects: Formation of ice at the expansion valve causing blockage and erratic operation, corrosion within the system, formation of sludge and acids (especially with certain refrigerants), potential compressor damage. Remedial Action: Install or replace the filter-drier in the liquid line. If contamination is severe, the refrigerant may need to be recovered, the system flushed, evacuated to a deep vacuum to remove all moisture, and recharged with fresh refrigerant and oil.

With reference to fresh water production: describe the term Reverse Osmosis.

Reverse Osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules, and larger particles from drinking water. Pressure is applied to overcome osmotic pressure, forcing pure water through the membrane while rejecting dissolved salts and other solutes on the other side. Signup and view all the answers

Describe, with the aid of a sketch, the construction and operation of an Active Controlled Tank roll damping system.

Construction: Consists of one or more tanks, typically positioned athwartships, partially filled with liquid (usually water). It includes sensors (like gyroscopes or accelerometers) to detect ship roll, a control system (computer), and actively controlled pumps or valves to rapidly transfer liquid between the port and starboard sides of the tank(s). Operation: Sensors detect the onset and direction of roll. The control system calculates the required counter-moment. The pumps/valves are actuated to transfer liquid to the 'uphill' side of the tank, creating a moment that opposes the ship's roll motion, thereby damping it. Signup and view all the answers

With reference to portable fire extinguishers: describe the examination and testing of portable fire extinguishers as specified in the UK and International legislation.
