GENERATOR
Use of generators in port
A minimum number of auxiliary motors must be running in port to maintain electrical requirements. The chief mate should be consulted regarding deck requirements. Reducing the number of auxiliary engines will lead not only to fuel savings, but also to a reduction in auxiliary services in the first place. It must be emphasized that in emergency situations such as oil spraying from a burst fuel pipe onto a running auxiliary system, the possibility of a power outage should not delay the decision to shut down hazardous equipment.
Using auxiliary engines for maneuvering
When the ship is underway and in confined waters, the use of the above should not be used as a sufficient number of auxiliary engines must be running to provide sufficient power to overcome any such emergency.
Reserve Auxiliary Engines
In the absence of maintenance, all non-running engines should be kept in an "auto-start" state to ensure rapid starting in the event of an emergency. A mechanic's assistant should regularly check the cylinders of these engines to ensure they are clear of water or fuel. Diesel engines should be changed more than once a week.
Serious damage can be caused by water leaking from defective turbofan housings into the cylinders through the exhaust manifolds. Water accumulation can also occur in the form of leaking cylinder heads or cylinder liners. Fuel can also accumulate as a result of leaking combustion equipment.
The drain valves in the exhaust and intake manifolds should remain open when the machines are at rest and should be checked regularly and checked for blockages, especially before stopping the machines.
Performance
Each type of engine is designed to operate within specified limits. These limits are specified in the manufacturer's instructions. Exhaust gas temperature is the best guide for cylinder outlet. It is important to maintain almost equal power output from each cylinder and this
should be checked every 500 hours by measuring peak pressures and balancing
individual loads on cylinders or cylinder blocks in V-type engines.
lubricating oil(sailor's work)
Detergent lubricating oils are widely used throughout the fleet and auxiliary lubrication of diesel engines. To fully benefit from the extended life of these oils, the oil should only be changed under the following conditions:
As per the maintenance schedule.
If the analytical report states that the oil is no longer suitable for exploitation.
If fuel oil or water is contaminated.
Oil samples, unless otherwise instructed, must be delivered as requested by the relevant oil company.
Most types of diesel auxiliary engines are susceptible to lube oil contamination by fuel, caused by fuel from the fuel valves and fuel pump entering the crankcase or running at light loads for long periods of time. Contamination can cause serious consequences, including damage to bearings and crankshafts. It is important that regular inspections are carried out on fuel systems to keep them free of leaks.
Particular attention should be paid to the cylinder cover and entablature drainage devices.
The dangers that arise when mixing different types of oil are very great. Under no circumstances should cleaning oil for use in auxiliary engines be added to the main engine system oils.
Cleaning oils, when no longer serviceable, must be disposed of either by burning or, where this is not possible, by being retained on board for subsequent landing.
Testing (sailor work)
Alarms and auxiliary diesel engine shutdown should be checked in accordance with the routine maintenance instructions at intervals of not more than three months and the relevant parts specified in the generator workbook. In all cases where such tests have been carried out, a corresponding entry must be made in the machine registration log.
