This document package includes engineering drawings and specifications for the engine and generator cooling system for two 2400 HP towboats required by the U.S. Army Corps of Engineers under Solicitation W912BU-23-B-0026. The drawings show layouts for the Cummins QSK19M main engine and DuraMax generator coolers, expansion tanks, piping sizes and materials, valves, fittings, and penetration details. Cooling calculations and general notes provide requirements for system design, testing, labeling, installation and vessel classification. The solicitation seeks offers for the construction of two towboats in accordance with the specifications by December 2024.
