This Concept Map, created with IHMC CmapTools, has information related to: Prepare Main Plant for Manoeuvring from Port Condition (Part2), PART 2 Once the main steam line pressure is at normal, open the main boilers superheated steam stop valves to the main turbine, open the main boilers superheated steam stop valves to the main turbine Disengage the turning gear Advice the bridge that the main turbine will beoperated and confirm that the propellor area is clear, 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 rev/min. Repeat for astern movement. While the above is being undertaken, the main turbine is checked to ensure it turns satisfactory in both directions., At the emergency manual manoeuvring valve position, turn the main turbines in the ahead and astern directions a couple of times and confirm all equipment is in good clear Reset main turbine trip, Advice the bridge that the main turbine will beoperated and confirm that the propellor area is clear Close the warming through steam valve At the emergency manual manoeuvring valve position, turn the main turbines in the ahead and astern directions a couple of times and confirm all equipment is in good clear, emergency manual manoeuvring valve back to the neutral With the manoeuvring controls in the 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 rev/min. Repeat for astern movement., main turbine trip from the manual stations at the bridge, ECR and turbine side. ???? PART 3, the main turbine is checked to ensure it turns satisfactory in both directions. Testing of main turbine trip from the manual stations at the bridge, ECR and turbine side., main turbine trip With the manoeuvring controls in the 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 rev/min. Repeat for astern movement., At the emergency manual manoeuvring valve position, turn the main turbines in the ahead and astern directions a couple of times and confirm all equipment is in good clear Set emergency manual manoeuvring valve back to the neutral
