U.S. Coast Guard (USCG) Sentinel Class MTU 20V4000M93L QL4 Engine Overhauls

The U.S. Coast Guard’s Surface Forces Logistics Center is seeking proposals for the overhaul of four Sentinel Class MTU 20V4000M93L QL4 marine diesel engines under a firm, fixed-price contract, with performance restricted to a single source—Rolls-Royce Solutions America, Inc.—due to proprietary technical requirements that only the original equipment manufacturer can fulfill. The work includes full engine overhauls in strict compliance with OEM specifications including the MTU Maintenance Schedule MA50075 and Preservation and Re-preservation Specification A001070, utilizing only authorized parts, processes, and proprietary data accessible through a current distributor agreement. Contractors must conduct complete inspections, perform dynamometer testing to full load at 4,216 KW on-site, submit detailed Engine Wear Analysis Reports and test records, and incorporate all applicable OEM service bulletins at no additional cost to the government. Each engine must be preserved using NIST-traceable standards, packaged in approved containers—including the government-furnished steel shipping container NSN 8150-01-F18-5402—with internal bracing, climate-controlled protection, and a plastic envelope containing inspection reports and caution tags. All deliverables must be marked in accordance with strict specifications: machine-stenciled black-on-white labels at least two inches high, displaying the NSN, part number, serial number, contract number, shipping weight, preservation date, and condition code, along with mandatory instructional markings on all sides. Bar coding is required per MIL-STD-129R using both Code 39 and PDF417 symbologies and must include the NSN, contract number, shipping weight, and other specified data elements. The overhauled engines will be shipped to the USCG central warehouse in Baltimore, Maryland, with the contractor bearing all packaging, labeling, and freight costs. The contract expects a six-month performance period, includes a one-year or 1,000-hour warranty from installation, and necessitates access to RRSA’s secure IT portal and certified personnel. Responses to this sources-sought notice are due by May 26, 2026, and must be emailed directly to the designated point of contact, with no formal competitive evaluation planned due to the sole-source nature of the requirement. All submissions must include the proposer’s SAM Unique Entity Identifier, size status, and evidence of OEM distributorship.
