and technicians are qualified for tasks assigned and allsafety equipment is on station before starting changeout.COORDINATIONYou can reduce or eliminate wasted of time byproperly coordinating several tasks throughout thechangeout. Simple things such as the proper placementof the special support equipment (SSE) containers caneliminate extra walking and moving of components.The SSE containers should be placed within the reachof the crane to avoid unnecessary movement ofequipment into the lift area. Crane service must becontrolled and used exclusively for the changeout. Theengine containers should be brought to the site as soonas possible so they can be opened and ready forinstallation when scheduled.T e a m m e m b e r s m u s t c o o r d i n a t e a m o n g s tthemselves for certain functions, such as the removaland installation of components and the constant passingof fixtures down and into the module. Communicationbetween team members during the changeout process isvery important.One way you can enhance bothteamwork and communications is by the use of portableradio equipment.POST CHANGEOUT REQUIREMENTSWith the completion of an engine changeout, youmust return the SSE and container to the cognizantrepair (support) facility. The damaged engine ispackaged in a container and is then shipped to theappropriate NADEP for repairs. The paper workinvolved in the changeout is lengthy, but necessary forproper documentation.careful preparation of SSEcontainers and engine containers will ensure they willreach their final destination with no shipping damage.Returning ContainersReturning the replaced gas generator, powerturbine,” and containers requires that the majorcomponents plus the T5.4 and Pt5.4 harnesses and thespeed sensors of that engine be packed within thecontainers. The completed log book is also returnedwith the container. After everything is secured withinthe containers and the desiccant bags have been driedout/changed, the cover is bolted down and pressurizedwith nitrogen for shipment. The ship’s supplydepartment is responsible for shipping the enginecontainers to the designated NADEP.When the SSE containers have been completelyinventoried, restacked, and secured, the supply systemis responsible for returning the empty containers to theirplace of origin.The 05X32 office of NAVSEA isnotified of the condition of the containers by the teamleader via the chain of command.ReportsReports from the team leader require the completionof the record log book for each component and theproper closeout of that log before stowage in the enginecontainers. All entries should be complete up to the timeof changeout, checked for correctness, and signed offby the engineer officer. The SSE containers that wereinventoried on arrival are to be inventoried again atcompletion for reissue to the next user. The engineerofficer and main propulsion assistant are required bysquadron directives to notify the proper people of anyirregularities at the completion of the changeout. Iflessons were learned because of the changeout, notifythe people concerned.Any unique or suspectoccurrences could be very valuable sources ofinformation.LESSONS LEARNEDThe following section describes some lessonslearned during engine changeouts.Pierside ChangeoutsSince the first changeout on the SPRUANCE classships, problem areas and past discrepancies duringpierside changeouts have been numerous. Problemssuch as location of the equipment and containers atpierside can delay the job. When equipment orcontainers are placed out of the crane’s reach, the delayis costly and frustrating.Some changeouts have been hampered by craneservice that was not totally dedicated to the job of enginechangeout. Many hours were lost awaiting the crane.Crane services are needed full time throughout thechangeout. All concerned personnel should realize thatto complete the changeout on time, the crane andoperator’s services are required the full 36 hours.Engine lifting is not all that is required of the crane.Every component of the rail system plus all the liftfixtures require crane services. The crane will be inconstant use, especially when the personnel basket isused. Personnel are also required to check the engine’sguide rollers in the permanently mounted guide tracksfor freedom of movement.2-30
