This document is a technical specification and schematic for an Auxiliary Sea Water Cooling System designed for military application, specifically for the Military Sealift Command (MSC) operated by the U.S. Navy. The system is engineered to provide cooling water to the main propulsion motor and associated auxiliary equipment aboard vessels.

The system includes multiple operational modes and components: an auxiliary cooling water to main propulsion motor function, a seawater supply for operation, and precise suction and discharge requirements for selected isolation points. Key operational features include methods to orient operations, procedures to operate selected isolation valves and open discharge valves, settings for operational controller flow reading valves, and opening of related cooling water pump suction and discharge valves. The system incorporates safety precautions such as ensuring crew members understand dangerous valves and open discharge points, operating in controlled manner with proper relief valve monitoring, and maintaining awareness of hot water discharge locations and potential steam hazards. Additional safety measures address pump operation when seawater suction is not available, proper isolation procedures, and guidelines for relieving air from the system. General notes indicate the system design accommodates specific operational parameters and the technical drawing identifies applicable components through a referenced parts list and includes specification callouts for materials, dimensions, and equipment compatibility relevant to naval vessel auxiliary systems.
