This Concept Map, created with IHMC CmapTools, has information related to: Main Plant at Finish with Engines, As such, the turbine will turn on the auto-spin steam system Close Main steam stop valve, evacuate the main steam line pressure to approximately 490kPa, using the main turbine ahead and astern manoeuvres and then trip turbine Engage and start the turning gear The main turbine is now stopped and turning slowly with the warming steam on line, Put the main turbine to manual and from the ECR evacuate the main steam line pressure to approximately 490kPa, using the main turbine ahead and astern manoeuvres and then trip turbine, Bridge will: 1. transfer the control of the main turbines to the engine room 2. place the telegraph at FWE although the telegraph is indication FWE, the turbine controls are still on automatic As such, the turbine will turn on the auto-spin steam system, unless the turbine is to be shut down for repairs or another specific reason When in port crack open the main turbine stop valve bypass valves and maintain a pressure of approximately 200kPa, crack open the main turbine stop valve bypass valves and maintain a pressure of approximately 200kPa Ensure boilers are firing on dual fuel if possible when in port, thus preventing gas being vented to the atmosphere, As such, the turbine will turn on the auto-spin steam system Open warming through line, The main turbine is now stopped and turning slowly with the warming steam on line this is the condition the plant is normally left in while awaiting port operations unless the turbine is to be shut down for repairs or another specific reason, Main steam stop valve Switch the auto-spin system off Put the main turbine to manual and, warming through line Switch the auto-spin system off Put the main turbine to manual and, Vessel is Manoeuring on Bridge Control when all movemements of the main turbines are completed Bridge will: 1. transfer the control of the main turbines to the engine room 2. place the telegraph at FWE, boilers are firing on dual fuel if possible when in port, thus preventing gas being vented to the atmosphere ???? Engine Room is now Ready for Cargo Operations
