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

The U.S. Coast Guard is procuring a QL4 overhaul for four MTU 20V4000M93L main propulsion diesel engines currently in Condition F, critical to the operational readiness of its 154-foot Fast Response Cutters. These 20-cylinder diesel engines require a comprehensive, high-end overhaul to restore performance and ensure long-term reliability as the Coast Guard continues to integrate new cutters into its fleet. The overhaul must be completed with the capability to dyno test each engine at 100 percent rated power on site, guaranteeing full functional validation before reinstallation. The procurement is competitively bid through the MTU dealership network, with a focus on leveraging specialized expertise within the small business community, as indicated by the SBA small business set-aside classification. The work will be performed in Baltimore, Maryland, and is managed by the Surface Forces Logistics Center’s Patrol Boat Product Line to align with the Coast Guard’s broader maintenance and sustainment strategy for its Sentinel-class fleet.
