INDUSTRY INVESTMENT: $550K | NSRP INVESTMENT $499K
The objective of this project is to design, test, and develop revised drawings for a fire resistant variant of two sizes of the new standardized family of watertight single doors developed during the prior NSRP Standardization of Watertight Closures Project, for installation at fire zone bulkheads.
The problem that the project team is addressing has to do with the impact of increased fire separation requirements that NAVSEA will invoke on future ship programs, such as the Future Frigate and the Large Surface Combatant. Navy ship program managers may also invoke the requirement at some point on existing surface ship programs.
The technical approach is to modify the design of two sizes of the new standardized family of watertight single doors by adding fire resistant gasket material that will protect the watertight gasket from fire damage, thereby providing protection from both fire spread and progressive flooding.
KEY DELIVERABLES / BENEFITS
Cost reductions will be realized through elimination of the need for installing two doors back-to-back at fire zone boundaries, one being a fire door and the other being a watertight door. The economic benefit will depend on how many doors pass through fire zone boundaries for a given ship.
