Like every other machinery, the turbine generator of the ship also needs to start under sequential starting procedure to avoid trouble free operation of the whole system. The correct procedure ensures that no part of the machinery goes through any kind of stress- thermal or mechanical. It also helps the ship to operate without wasting any extra time.
The correct starting procedure for steam Turbine Generator onboard ship is as follows:
- Check turbo generator lube oil sump level and drain it for water. Replenish it if level is less than normal.
- Start the lube oil priming pump from the local station and check the lube oil pressure. Put the priming pump on auto.
- Check and fill up the Turbine Generator vacuum pump operating water tank to normal level.
- Check vacuum condenser condensate level from the condensate pump. Put the pump on auto so that the level is maintained all the time.
- Operate the steam drain valve to drain any condensed water from the steam line to avoid excessive hammering and vibration while starting turbo generator.
- Open the main steam inlet valve for turbo generator.
- Adjust the gland steam pressure to normal level.
- Check and open the sea water valves for vacuum pump cooler, T/G lube oil cooler and vacuum condenser are opened.
- Start the vacuum pump and bring up the vacuum in the condenser.
- Open condensate pump valves and switch on the pump.
- Check whether the condensate vacuum, gland steam pressure, steam inlet pressure, and lube oil pressure are normal.
- Start turbo generator from the local station and close the drain in the steam line.
- Check first and second stage steam pressure.
- Check condenser vacuum and water level.
- Check lube oil pressure and vibration levels.
- Check turbo generator speed, voltage, frequency, vacuum, condenser level and other parameters.
- Give control to remote station from the local control and take the TG on load.
