MODUK DEF STAN 02-136 PDF

This document defines the design policy for Watertight Integrity for submarines. It is applicable to both new design and existing classes of submarine.

This document seeks to discuss watertight integrity for submarines and the consequences of its loss, define the watertight envelope and hazards and consequent modes of failure, and the design principles to minimise the likelihood and consequences of failure of watertight integrity. Finally specific design, through life testing and inspection requirements are covered.

Design responsibilities are considered in the light of the implications of MOD's policy on Ship Safety Management and JSP 430.

This document does not consider collapse of the pressure hull as a watertight integrity issue; hull design is covered by MAP 01-074 and Def Stan 09-50.

This document is compatible with the consensus achieved on submarine survivability policy after an extended debate resulting in a paper reference DGSM/DNA&FP/109/1/1/1 dated May 1997.
