The testing involved 14 different evaluations over four days, confirming that the system fulfils the requirements of the US Navy.  

These included assessments of normal and emergency operations, testing modes, and crucial filling and draining features.  

The Maritime Sustainment Technology and Innovation Consortium (MSTIC) funded the testing of the CLCS, which is engineered to enhance the efficiency of submarine dry dock maintenance.

“By leveraging MSTIC’s support alongside our technical capabilities, we deliver state-of-the-art solutions that address evolving client needs and enhance critical naval operations worldwide.” 

The main mission of Pearl Harbor Naval Shipyard is to deliver regional maintenance services at the depot and intermediate levels, ensuring the operational readiness of surface ships and submarines. 

The CLCS incorporates a ship service skid for circulating cooling water through the submarine and a chilled water skid that works with air-cooled chillers.  

The system aims to improve operational efficiency, minimise corrosion, streamline maintenance schedules, and guarantee the reliability of the system over time.  

These benefits are said to be required for naval vessels in regions with environmental sensitivities or strict water management laws.  

Earlier this month, Fairbanks Morse Defense opened a new service centre in Guam, aimed at bolstering support for the US Navy’s Pacific fleet operations. 

This enhances the company’s aim to deliver services and reinforce the effectiveness of global naval forces.
