Main engine
Responsibility
Planned maintenance schedules should be followed whenever possible, but this should in no way diminish the responsibility of the chief engineer, second engineer and second starting engineer for the efficient and reliable operation of the installation.
The chief engineer must personally supervise the entire journey on a daily basis and must inform the second engineer. Mechanic to ensure the department is aware of any changed operating or maintenance conditions.
Starting Precautions
It is necessary to keep records of the termination of the contract and the conduct of surveys.
Before initial start-up, the engine must be turned at least one full turn by turning the rotary mechanism with all indicator valves open and at the same time observing the load on the ammeter. During this rotation, the indicator valves and drains should be checked for water in any cylinder.
In this case, all manufacturer precautions must be observed when starting the engine.
As an additional means of detecting leaks, as well as a precaution against garbage disposal fires, all garbage disposal drains and garbage disposal air spaces should be frequently purged with compressed air to avoid the accumulation of water and oil. Garbage areas should be cleaned regularly.
When the main engines are shut down for any period of time, the exhaust manifold and main drain pipes, if installed, must be open and remain open until the engine is restarted.
Performance
Each motor type is designed to operate at a specified continuous power rating, maximum specified pressure, and maximum specified rotational speed. The second mechanic at the start should ensure that these limits can be found in the manufacturer's manual and test report.
Power determination
Accurate and reliable power determination is a vital part of the analysis
machine condition and hull performance. Power, specific fuel consumption and total fuel consumption must be recorded in appropriate metric units.
Cooling system
Suppressed fresh water should always be used to cool cylinder liners, covers and pistons if necessary. Fresh water discharge temperature should be as close as possible to the engine manufacturer's recommendations to reduce thermal stress. The concentration of corrosion inhibitors should be maintained within the recommended limits specified by the supplier.
Engines with oil-cooled pistons should have oil drain temperatures close to the engine manufacturer's specifications. Salt water cooled heat exchangers must be operated in accordance with the manufacturer's instructions.
Maneuvering (second mechanic at start)
For less than six hours before the engine is started, the cooling water in the jacket must be circulated and slowly warmed to normal operating temperature.
Lube oil pumps should be running and oil circulating for the last three hours. During warm-up and circulation, the engine should be carefully checked for leaks, and indicator valves and purge drains observed during the last full rotation using the rotary mechanism.
The maneuvering equipment and launch system should be well tested before going into standby mode, and all water should be drained from the overhead lines.
Before starting work, the chief mechanic should always make sure that the turning mechanism is turned off. The fuel oil must be circulated where it is needed, and its temperature must be increased to ensure sufficient atomization triggering.
Whenever possible, the second engineer will start, maneuvering should be carried out using heavy fuel at all times, including channel passages.
Once the order is received to complete the engines, the indicator valves and purge drains must be opened, the air start systems isolated and the turning mechanism turned on.
Cooling water flow in the jacket must be maintained for at least three hours to minimize the rate of change in cylinder liner temperature. Likewise, full flow of piston coolant and bearing lubrication must be maintained for at least one hour (second mechanic at start).
During the circulation period, indicators and purge effluents should be observed to identify signs of leakage.
