SUBMARINE POTABLE WATER TANK

Overview

Submarine potable water tank preservation requires special care due to the potential impact on the crew’s health and well being. Potable water is used for drinking and food preparation. Coating requirements for these tanks are more stringent than other tanks; coating system replacement is required if the tank has more than 1% localized coating failure. The coatings specified for use in potable water tanks on submarines are MIL-PRF-23236 Type VII, Class 9 or 9/18 and MIL-DTL-24441 Type III.

Surface Preparation

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 NAVSEA Standard Item (NSI) 009-32 and the Submarine Maintenance Standard (SMS) 6310-081-015 – Submarine Preservation.

Depot Repairs

For depot repairs, refer to SMS 6310-081-015 and NSI 009-32. NSI 009-32 is the governing document for preservation requirements.

Submariner Repairs

Potable water tanks are usually not entered by submariners between availabilities but if they need to enter for any reason, 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

New construction submarines are painted in accordance with the submarine build specification for that class of submarine.
