MOSHIP Criteria Manual.pdf

This document is the Mother Ship (MOSHIP) Criteria Manual for U.S. Navy Submarine Rescue, Revision E, issued June 2019, which serves as a specification and evaluation guide for vessels designated to support submarine rescue and intervention systems.

The manual establishes comprehensive technical and operational requirements for MOSHIPs and Mother Barges of Opportunity (MOBARGEs) to support the Submarine Rescue Diving and Recompression System (SRDRS) and related rescue systems. Key vessel specifications include: Dynamic Positioning System rated at minimum IMO Class 2 equivalent; mooring capabilities proportional to 500 ft radius at 2000 ft depth; cargo deck loading capacity of 1025 lb/ft² (5 tonnes/m²) for SRS installations; clear aft deck areas ranging from 2904 ft² to 3920 ft² depending on system type; electrical power supply of 350 kW at 480 VAC for SRS with backup capability; and installed cranes with Safe Working Load capacities of 12.5 to 6000 tons depending on system requirements. MOSHIPs must support personnel of 31 to 90 individuals for up to 10 days unreplenished operations, provide 20,500 gallons of diesel fuel, 2,000 gallons of freshwater, and maintain life-saving equipment compliant with SOLAS regulations. For MOBARGEs, vessels must be certified for Open Ocean Manned Operations per USCG/ABS regulations and equipped with emergency alarm systems, fire protection, boarding ladder access, and sufficient deck area for four capstans supporting Light Weight Mooring Systems in 2,000 feet of water. The document includes detailed vessel scoring matrices (Gold, Silver, Bronze, Tin/Red ratings) and comprehensive survey checklists in appendices for evaluating vessel compliance with SRDRS, SRCFS, ROV LARS, SILOS, LWMS, and NATO submarine rescue systems.
