Preparations for a long sea trip involve a long list of tasks that need to be carried out before the ship departs from the port. This article is about the tasks that need to be carried out to ensure a safe and uneventful trip. In the following, tasks are listed for easier comprehension.
The following checklist concerns tasks to be undertaken by the engine room crew before departure from the port, assuming cold start with the boiler and generator running.
Tasks to be carried out 24 hours before first departure
- Oil level measurement by level checking or sounding of the bunker tanks and temperature check to make sure that temperature remains constant at approximately 40 degrees or as indicated in the analysis report by releasing steam. This task is necessary when transferring oil from the bunker tank to the settling tank. Cold oil temperature leads to high viscosity which might cause damages to the pump.
- Level check at the jacket water header tank. Overfilling must be avoided as it leads to overflow upon engine start due to expansion of the water in the tank.
- When a separate main engine system is provided, once the aforementioned step is completed and water level is checked, start the jacket water circulating pumps.
- Main engine jacket water temperature check. Temperature must be kept at approximately 60 degrees to prevent the risk of leakage into the scavenge space at lower temperatures.
Tasks to be carried out 6 hours before departure
- Oil level check in the main engine sump, turbocharger tank.
- Starting of lubricating oil, cross head (for sulzer engines) and turbocharger pumps. This task is to be carried out by the duty engineer.
- Oil flow check via the sight glass of the turbocharger outlet.
- Lube oil, turbocharger and cross head pump pressure check.
- Shaft bearing pump starting and header tank level check.
- Sequential starting of all these pumps is generally possible via a UMS program once the engine room rounds and level checking are completed.
Tasks to be carried out 1 hour before departure
- Report by the chief engineer after the final quick round of the engine room before departure.
- Oil, header tank and cylinder oil tank level checks.
- Fuel oil, booster, lube oil pump pressure check.
- Air bottle drainage to discharge any remaining quantity of water.
- Check that turning gear is out.
- Running machinery parameter check.
- Starting of additional generator to meet increased power demand for winches and thrusters.
- Starting of exhaust gas boiler water circulating pump.
- Confirmation of proper telegraph operation in cooperation with on-duty deck officer.
- Telegraph local and remote panel check.
- Emergency telephone operation check.
- Steering gear check for leaks and port to starboard movement while the chief engineer is in the control room.
- Steering gear limit switch operation check.
- Steering gear gyro reading check and cross-referencing to on bridge reading.
Tasks to be carried out 15 minutes before departure
- Opening of main engine main air starting valve.
- Confirmation that all air compressors are set to auto and all air bottles are full.
- Checking for water ingress in the main engine by blowing air into the main engine with the indicator cocks open.
- If no leaks or ingress is detected, the chief engineer reports and indicator cocks are closed.
- Closing of turbocharger drain valves.
- Engine ready status reported to the captain on bridge by the chief engineer and transfer of control from the engine control room to the bridge.
- Taking of main engine, generator and boiler flow meter counter readings to calculate oil quantity at the port.
Tasks to be carried out while engine is running
- Engine room round repeated.
- Check for any abnormality.
- Main engine parameter check, e.g. exhaust valve, jacket water temperature, etc.
- Closing of jacket water steam heating, if it is not controlled automatically.
- Opening of other sea suction valve once the ship has left the port and the pilot has departed.
Tasks to be carried out whilst ship is full away
- Stopping of additional generator.
- Stopping of boiler, if an exhaust gas boiler is provided.
- Starting of fresh water generator.
- Opening of sewage overboard valve.
- Starting of turbine and shaft generator, if provided.
- Taking of new flow meter counter reading to calculate consumed fuel quantity from port to full away.
- Watch change to next duty engineer, if necessary.
- For UMS ships, once engine room rounds are completed, the bridge is notified with respect to breaks.
