HK Engine Operator Grade 3 flashcards

31 cards. Read the term and the definition here. The deck at the top of this page is optional.

Watch handover acceptance

The relieving engineer takes responsibility only after a face-to-face briefing on plant status, defects, ongoing work, and standing orders, and both parties record the handover in the logbook.

UMS alarm testing

Before leaving the machinery space unattended, alarm and safety systems are proven in test and any defeated alarm is logged with justification and a standing instruction covering the risk.

Engine room bell book

A record of every telegraph order and its time and response during manoeuvring, written when the order is received rather than reconstructed later, supporting later investigation.

Engine standby readiness

The condition in which the main engine has been tested ahead and astern and the bridge has been told the engine is ready for immediate manoeuvring orders.

Deviation response order

A sequence for abnormal readings: verify the instrument, find the cause, reduce load or change over, inform the bridge if manoeuvrability is affected, then record the event.

Watchkeeping round records

Logged readings covering main engine parameters, auxiliary loads, pressures and temperatures against limits, tank levels, bilge state, and observed leaks or abnormal noise.

Refusal of handover

The right of an arriving engineer to decline responsibility when the plant state is unclear or unsafe, leaving the outgoing engineer on watch until the situation is resolved.

Manoeuvring telegraph log

The timed record of bridge orders and engine responses during port arrival and departure, used to show compliance and to reconstruct events after an incident.

Scavenge pressure diagnosis

Scavenge air pressure should rise with load; a fall at constant load points to air cooler fouling, blower fault, or leaking scavenge trunking rather than a fuel problem.

Peak pressure adjustment

Cylinder peak pressure is compared with shop trial values and corrected by changing compression ratio or fuel timing as the engine maker specifies.

Fuel viscosity at engine

Residual fuel is heated so inlet viscosity stays in the maker's band, commonly around 10 to 15 cSt; too high spoils atomisation and too low risks seizure.

Purifier gravity disc

The disc is chosen from fuel density at the separating temperature; too small a disc loses oil to the sludge side, too large a disc leaves water in the cleaned oil.

Lube oil trend analysis

Single samples matter less than trends: rising iron or copper, rising water, falling TBN, and rising insolubles each indicate a specific wear or contamination path.

Jacket water temperature

Cooling water is treated against corrosion and scale and held near the maker's temperature; a sudden rise with falling pressure suggests air ingress or pump fault.

Air receiver draining

Condensate is drained from starting air receivers at intervals, and safety valves and gauges are checked; capacity must allow the maker's number of consecutive starts.

Planned maintenance basis

Maintenance intervals are set by running hours, condition monitoring, and maker's recommendations; deferred items are risk-assessed and recorded with a new target date.

Indicator diagram use

A pressure-volume diagram taken from a cylinder shows combustion and compression quality and is compared with trial values to detect timing, injector, or ring faults.

Fuel density and separation

Separation temperature is set so the fuel's density at that temperature stays below the disc rating; density rises as temperature falls, so cold fuel separates poorly.

Enclosed space entry permit

A permit issued before entry after testing oxygen near 20.9 percent, hydrocarbons, and toxic gas, with a competent standby person at the entrance and rescue gear ready.

Fixed CO2 release condition

Fixed CO2 is released into an engine room only after all personnel are accounted for, fuel and ventilation are shut off, and the space is fully sealed.

Oil record book entries

Bunkering, transfers, separater discharges below 15 ppm, sludge disposal, and soundings are recorded and signed by the officer in charge and the master.

Oily water separator limit

Machinery space bilge water may be discharged only through 15 ppm equipment fitted with an alarm and automatic stopping device, and never in special areas.

Enclosed space rescue rule

Rescuers never enter an atmosphere without breathing apparatus; unprotected rescue attempts are the main cause of multiple fatalities in tank and hold incidents.

Emergency equipment testing

Emergency generator, emergency fire pump, and emergency lighting are tested at set intervals with results recorded, and failures are rectified before the next voyage.

Garbage segregation at sea

Garbage is separated by category and recorded in the garbage record book or management plan; plastics are never discharged overboard under any circumstances.

Engine room fire first actions

Raise the alarm, stop fuel supply and ventilation, close all openings, and fight the fire with the appropriate medium while accounting for every person on board.

Local Vessels Ordinance

Hong Kong's Merchant Shipping (Local Vessels) Ordinance, Cap. 548, and its regulations govern certification, manning, and operation of local vessels in Hong Kong waters.

Marine Department licensing

The Marine Department issues the Certificate of Survey and the vessel licence; both must be valid and consistent with the vessel's type and intended use.

Local manning scale

The licence conditions set the certificate of competency and crew numbers for the vessel type, tonnage, and propulsion power, and the engine room watch must meet them.

Hong Kong bunkering safety

Bunkering in Hong Kong waters follows local safety requirements: notification, spill contingency arrangements in place, scuppers plugged, and transfer supervised throughout.

Accident reporting duty

The master must report marine accidents and dangerous occurrences to the Marine Department promptly, and the engine department supplies the technical facts for that report.
