Diesel Generator Preservation Procedure

Equipment shall be packed, securely anchored (skid-mounted when required), and weather protected. Separate, loose, or spare parts shall be boxed, and each part individually protected as required. Each container shall be marked both inside and outside with the equipment number and service for which the parts are intended.
Each container shall include complete Bills of Material identifying each part. In some instances, for example instruments, specific tagging shall be required.
Equipment shall be free from water before shipment preparation.
Bearing assemblies shall be fully protected from rusting and from entry of moisture and dirt.
One complete set of installation, operation, and maintenance instructions shall be packed with the equipment.

Generator Internal Preservation

Internals shall be sprayed or fog machined. They shall be sprayed with a suitable preservative while the generator rotor is being turned slowly in its bearings thoroughly through all access openings in sufficient quantity to ensure coverage of all internal parts. Drains shall be left open during spraying to prevent liquid buildup within the generator.
Internals of bearing housings shall be sprayed with circulating oil. Bearing housing openings shall be blind flanged or plugged using standard blind flanges and gaskets. Bearing housing sump shall be filled with circulating oil to a level about 75 mm from the bottom of the sump before installing the bearing housing cover.
Desiccant bags shall be tied securely to flange covers, to ensure that they are removed when the cover is removed.

Immediately upon completion of all tests and inspection, all exposed- machined surfaces including soleplates and bolting shall be coated with a rust preventative.
To provide a clean epoxy grouting surface, the bottom of all baseplates and soleplates shall be sandblasted to near white metal and immediately covered with epoxy paint.
Solid steel plugs shall be used instead of plastic plugs for any part that is pressurized during startup or operation.
Open ends of tubes and pipe shall be capped for protection. Taping shall not be considered adequate.
Flanged openings shall be provided with full size steel closures of 5 mm minimum thickness with full-face rubber gaskets and at least 4 full diameter bolts. A rust inhibitor shall be applied to all flange faces.
