High Performance Marine Diesel Closed Coolant System for High Speed Combatant Craft

USSOCOM has expressed a desire to prevent the clogging of the seawater intakes aboard the SOC-R craft by exploring a closed-loop cooling system that does not require the use of off-board raw water. The desired solution will not degrade the current SOC-R craft capabilities by creating drag or causing cavitation that would affect the performance of the Hamilton jets, thereby reducing speed, would not interfere with the turning or navigation of the craft, and would be sufficiently robust to survive beaching at low speeds without structural damage and high speeds without major damage or loss of watertight integrity. GS Engineering will quickly work with United States Marine Inc. as well as Yanmar representatives to understand and quantify the cooling requirements of the craft"s engine and powertrain. Once the craft"s cooling requirements are understood, GS Engineering will perform a brief market study of commercially available closed-loop marine cooling products before developing a unique skin cooler specifically for the SOC-R which leverages extrusion and advanced welding manufacturing technology. The final solution will be packaged into the craft in such a manner that cooling requirements and performance objectives are maintained.
