This Concept Map, created with IHMC CmapTools, has information related to: Preparation of Main Plant for Manoeuvring from in Port Condition 3, For main turbine trip from the manual stations at the bridge, ECR and turbine side. to be continued Part 4, Disengage the turning gear. and inform the bridge "The main turbine will be operated and Confirm that the propellor area is clear.", Emergency manual manoeuvring valve back to the neutral position and reset the main turbine trip. With the manoeuvring controls in manual mode From the ECR with some attendance at the turbine side, operate the control to allow main steam into the turbine and rotate ahead at approximately 5 revolutions per minute. Repeat for astern movement. While the above is being undertaken, the main turbine is checked to ensure it turns satisfactorily in both directions., "The main turbine will be operated and Confirm that the propellor area is clear." proceed to Close the warming through steam valve., From the ECR with some attendance at the turbine side, operate the control to allow main steam into the turbine and rotate ahead at approximately 5 revolutions per minute. Repeat for astern movement. While the above is being undertaken, the main turbine is checked to ensure it turns satisfactorily in both directions. conduct test For main turbine trip from the manual stations at the bridge, ECR and turbine side., At the emergency manual manoeuvring valve back to the neutral position and reset the main turbine trip. set Emergency manual manoeuvring valve back to the neutral position and reset the main turbine trip., Close the warming through steam valve. ????? At the emergency manual manoeuvring valve back to the neutral position and reset the main turbine trip.
