SOW for Caterpillar D-398 Line Bore Inspection

RFQ NR 70Z080-20-Q-P45C2000

The U.S. Coast Guard is completing an overhaul of an engine used as a ship service diesel generator onboard CGC TAMPA. This engine is a Caterpillar D-398 series of V-12 design. The engine serial number is 66B7583.

The vessel will have the NO. 1 Ship Service Diesel Engine completely disassembled and flipped upside down to facilitate the crankshaft line bore inspection. The work will be completed within CGC TAMPA’s engine room on the 19th & 20th of August 2020 at the following address:

COMMANDING OFFICER

USCGC TAMPA (WMEC 902)

4000 COAST GUARD BLVD

PORTSMOUTH, VA 23703

ATTN: LT Erik Greer

The purpose of this inspection is to compare the actual crank line bore measurements as found to the Caterpillar (OEM) specifications for a D-398 engine. Once the readings have been taken the machinist is to provide a preliminary report to the ships Engineer Officer detailing the results for each main bearing. The report must include a recovery plan detailing what actions should be taken (if necessary) to return the bores to OEM specifications. A final report must be provided in writing to the ships Engineer Officer prior to departing the vessel.

As we have a limited time frame to work within, the inspection and any necessary machine work must be completed on the dates given above. Because of the compressed schedule any machine work (once approved) can be conducted non-stop until completed. The Coast Guard will provide an inspector/assistant to support this effort. Engine reassembly will commence immediately following this inspection.

NOTE - This work is restricted to Caterpillar Authorized Parts & Service Centers only as the timeline is extremely short and can’t be extended without a negative impact to the project timeline or vessel’s operational schedule. CAT Authorized Service Centers are very familiar with this particular engine, the work involved in completing the inspection and the machine work that may be required to correct for misalignment.

As the vessel will be deployed up until the start of this project all questions should be directed to Phillip. W. Norris at 757-628-4556 or via email at Phillip.W.Norris@uscg.mil
