OVERHAUL OF CATERPILLAR MARINE DIESEL ENGINE ONBOARD USCG CUTTERS

The U.S. Coast Guard, through the Department of Homeland Security’s Sflc Procurement Branch 2 in Alameda, California, is conducting market research to identify qualified contractors for the overhaul of Caterpillar marine diesel engines onboard its cutters, using solicitation number 70Z08526CATIDIQ. This sources-sought notice targets companies capable of providing full-service, authorized, and certified technical support for the repair, maintenance, and overhaul of Caterpillar D353, D379, D3304, D3306, D3406, D3412, D3508, and D3608 engine models used in Seagoing and Coastal Buoy Tenders, Inland and River Tenders, and Tugs. The government estimates an annual demand of 29 to 38 main propulsion diesel engines requiring service based on OEM-recommended periodicity. Contractors must demonstrate a minimum of six years of relevant experience, possess direct access or a formal agreement to obtain Caterpillar proprietary components through licensing, certified technicians, or authorized agreements, and be registered in the System for Award Management (SAM) as mandated by FAR Clause 52.232-33. Responses must include company identification, DUNS number, business size certification under NAICS code 336611, documentation validating small business status if claimed, past performance details with contract numbers and points of contact, and a formal statement affirming intent to submit a proposal as a prime contractor if a formal solicitation is issued. The anticipated contract structure is an Indefinite Delivery Indefinite Quantity (IDIQ) arrangement with a base year and four optional years, with engine overhauls typically performed onsite at the cutter’s homeport, though certain long-block renewals may be exceptions. All work must adhere strictly to original equipment manufacturer standards and utilize genuine Caterpillar-approved parts. Required technical deliverables include remanufactured engines certified to OEM specifications, comprehensive testing procedures such as CAMPAR testing, vibration analysis, engine timing synchronization, and valve rotator servicing, along with top-end or center-section overhauls as needed.
