The US Coast Guard requires four overhauls of Sentinel Class MTU 20V4000M93L QL4 engines, performed according to OEM specifications. Offers must come from vendors with a current OEM distributor agreement, access to proprietary data, and on-site full-load dynamometer testing capability. The contract is expected to be restricted to the OEM due to the government's lack of proprietary technical data. The firm-fixed-price contract covers open and inspection, standard labor, mandatory parts, and typical contingency parts, with shipping to Baltimore, Maryland. No budget amount or submission timeline is specified.
