3.3.2.1 During performance of testing, monitor all engine parameters for signs of misalignment or overheating (i.e. abnormal noises, vibrations, pressures, and temperatures). If any unusual readings are experienced, immediately secure the engine and troubleshoot to determine the cause

3.3.2.2 Obtain oil samples prior to operation (Step 1), prior to applying load (Step 9), and upon completion of successful load testing (Step 16). Submit all oil samples for lab analysis of wear particles.

3.3.2.3 Record all engine parameters on a log sheet for each Run-In Schedule step (Steps 1 thru 5) and every 15 minutes after (Steps 6 thru 16).

NOTE

In the event testing cannot be completed in a single day, the run-in may be continued the following day if necessary. Operate the engine until all temperatures are stabilized (consistent with the last recorded readings) and continue the run-in. Annotate the log sheet to indicate test resumption.

3.4 Engine preparation. After engine acceptance, the Contractor shall accomplish the following to prepare the engine for shipment.

3.4.1 Touch-up preservation, general. Prepare and coat all new and disturbed engine surfaces, as applicable, to match existing adjacent surfaces in accordance with SFLC Std Spec 6310, paragraph 3.1.13

(Touch-ups and minor coating repairs.)

3.4.2 Fluids. Drain and dispose of all fluids in accordance with federal, state, and local regulations.

3.4.3 System cleanliness protection. Take all necessary precautions to prevent the introduction of contaminants. Piping systems interface points shall be sealed with commercial grade plastic or metallic caps, plastic or metallic plugs, mating blanked covers, or with blank flanges attached with bolts. Plastic bags and duct tape are not acceptable.

3.4.4 Wrapping. The engine shall be shrink-wrapped in 6 mil or heavier polyethylene sheeting or otherwise covered and sealed to prevent water damage. To prevent adhesion between protective coverings and painted surfaces, protective coverings shall not be applied until the paint has cured (if applicable).

3.4.5 Crating. The wrapped engine shall be placed in a sturdy wooden shipping crate with the skid securely anchored to the crate bottom with bolts or lag screws. The crate shall be designed for movement with a forklift.

3.5 Documentation. The Contractor shall submit a CFR that provides an itemized list of all parts used in support of overhaul. This shall include OEM part names and part numbers for configuration management tracking.

3.6 Operational test – post installation. After completion of installation, the Contractor shall be present to witness Coast Guard operational testing onboard the vessel. The equipment will be operated through its full range of capabilities in all configurations and operating modes (including maximum available loading using ship’s load). Submit a CFR.
