Starting Procedure of Power Generation: From Cold Ship to Diesel Generator 1 and 2

In order to power up the ship, a specific starting procedure needs to be followed. This procedure involves the use of a simulator to simulate the cold ship condition and the starting of the diesel generators. Let's walk through the step-by-step process of starting the power generation.

Setting up the Simulator (2.1) Begin by setting up the Kongsberg simulator to simulate the cold ship condition. Set the simulator to fall chip as the initial condition. Press F1 to run the simulator and F7 to select the directories.

Checking the Emergency Generator (2.2) The first part of the procedure involves checking the emergency generator. Chief Engineer Pariser should go to directory 70, the emergency generator. Ensure that all breakers, including the emergency transformer, are in the on position, except for the spare breaker.

Emergency Switchboard and Main Switchboard (2.3) Next, Chief Engineer Pariser should move on to directory 73, the emergency switchboard. Put all the breakers in the on position on the freedom panels, including the emergency transformer breaker, except for the spare breaker. Then, go to directory 71, the main switchboard feeders, and put all the breakers in the on position, except for the spare breaker. Finally, Chief Engineer Pariser should go to directory 72, the main switchboard feeders, and put all the breakers in the on position.

Preparation of Sea Water Cooling (3) To prepare the sea water cooling system, Midshipman Argell will guide us through the step-by-step procedure.

Sea Water Cooling for Diesel Generators (3.1) Chief Engineer Predator should go to directory one, the sea water system. Open the sea water overboard bulb and the low suction sea chest inlet bulb. Open the shut-off bulb for the diesel generator one and two fresh water coolers and the sea water circulation line shut-off bulb. Enable the alarm alert for any alarms and acknowledge them.

Sea Water Cooling for Emergency Compressor (3.2) Midshipman Supa Midshipman Argell will now guide us through the procedure for preparing the emergency compressor. First, go to directory 59, the start air system. Open the emergency start air receiver inlet and outlet bulbs. Open the diesel generator one and two start air supply bulbs. Put the emergency compressor in local control and start it until the receiver pressure reaches at least 20 bars. Then, put the emergency compressor in remote control.

Starting the Diesel Generators (4) Now, let's proceed to the preparation and starting of the diesel generators. Midshipman Morale will explain the procedure for starting the diesel generator one.

Preparing the Diesel Generator 1 (4.1) Chief Engineer Passer should go to directory 75, the diesel generator one. Check the loop oil sampling level, ensuring it is between 30% to 80%. Open the loop oil filter number one. Manually start the lube oil priming pump. Check the level of the expansion tank and fill it up to the normal level. If there is no water flow, open the appropriate valves in directory 67.

Preparing the Diesel Generator 2 (4.2) Chief Engineer Parisher should go to directory 76, the diesel generator number two. Check the loop oil sampling tank level, ensuring it is between 30% to 80%. Open the loop oil filter number one. Manually start the lube oil priming pump. Check the level of the expansion tank and fill it up to the normal level. If there is no water flow, open the appropriate valves in directory 67.

Synchronization of Generators (5) To ensure the proper functioning of the generators, synchronization is necessary. Let's go through the procedure for synchronizing the generators.

Connecting the Additional Generator 1 (5.1) Chief Engineer Pariser should go to directory 70, the electric power plant. Press the voltage control of the diesel generator 1 and 2 and observe the voltage and frequency output requirement, which should be 440 volts and 60 hertz. Then, go to directory 141, the main switchboard diesel generator 1, and check the frequency, voltage, and current. Pressing the appropriate buttons, correct the breaker and connect it at 11 o'clock on the synchroscope.

Synchronizing the Two Generators (5.2) After connecting the additional generator 1, proceed with synchronizing the two generators. Start the auxiliary path again in directory 1, and then go to directory 72, the main switchboard feeders. Put the main transformer inlet breaker in the on position. Finally, go to directory 143, the main switchboard diesel generator 2. Start the frequency and voltage adjustments and connect the breaker. Adjust the frequency clockwise and connect the breaker at 11 o'clock on the synchroscope.

Other Procedures (6) Apart from starting the generators and synchronizing them, there are other procedures that need to be followed for the successful operation of the power generation system.

Conclusion (7) In conclusion, the starting procedure of power generation from a cold ship to diesel generators 1 and 2 involves several steps. These steps range from setting up the simulator, checking the emergency generator, preparing the sea water cooling systems, starting the diesel generators, and synchronizing them. Following these procedures ensures a smooth and efficient power generation process onboard the ship.
