SUBMARINE BILGES & MACHINERY SPACES
This section describes coating requirements for submarine machinery spaces, including engine rooms and auxiliary machinery rooms. Refer to NAVSEA Standard Item (NSI) 009-32 and the Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation for restrictions when accomplishing preservation in machinery spaces. For example, open abrasive blasting is not permitted in machinery spaces. Also, motor generators, electronics and engine rooms have specific requirements for protection against dust contamination and overspray.
To ensure proper coating adhesion, special attention should be paid to surface preparation of this area. All surface preparation work must be accomplished in accordance with NSI 009-32 and SMS 6310-081-015.
For depot repairs, refer to SMS 6310-081-015 and NSI 009-32. NSI 009-32 is the governing document for preservation requirements.
Submariners are primarily responsible for maintaining the machinery space coating system until repair activity maintenance is scheduled. Naval Ships’ Technical Manual: Chapter 631 (NSTM 631), Preservation of Ships in Service – General provides requirements, instructions, and guidance for surface preparation and coating application.
New construction submarines are painted in accordance with the submarine build specification for that class of submarine.
SUBMEPP provides centralized life-cycle maintenance solutions and support for U.S. Navy submarines and submersibles. SUBMEPP is under the Submarine Directorate of the Naval Sea Systems Command (NAVSEA).
The Naval Sea Systems Command (NAVSEA 05) is the technical authority for in-service submarine preservation-related work.
