The U.S. Coast Guard requires the immediate inspection and possible overhaul of one specific lubrication oil cooler, with delivery directly to the CGC JACOB POROO. The government believes only ZF Marine Propulsion Systems, LLC or their authorized repair facility can perform this work due to proprietary data and parts. Interested vendors must submit verification of their authorized status from the OEM within three calendar days of the notice posting. The award will be made on a lowest-price, technically-acceptable basis for a total firm-fixed price, including an inspection fee. Vendors must be registered in SAM.gov.
