Confirm the requirements for watertight closure documentation with key Navy technical personnel, and provide design documentation for previously approved doors that deviate from the current Navy standard.
On a large Navy ship there may well be dozens of unique door designs that deviate in some way from the Navy standard design, increasing part counts and procurement costs.
For ship programs that require shock qualification of watertight closures, the unique door designs that deviate in some way from the Navy standard design aren’t considered to be shock qualified. In many cases, the Navy will call for shock testing to be done to prove the shock resistance of the non-standard door design, which incurs additional costs.
The unique door designs that deviate in some way from the Navy standard design drive higher logistics costs due to having to maintain data on the door designs and separate spare parts packages.
The project work should lead to Navy documentation that incorporates a family of approved and qualified door designs that cover the vast majority of doors used on new construction ships. The revised documentation will also give accurate logistics data to ship maintainers and thereby support cost effective maintenance and repair.
