Objective:
The current practices for many ship designs call for transit block systems to be used when traversing watertight barriers. However, these systems are expensive, challenging to design for multiple and various cable passages, and may not fit every application in the most accommodating way. Sealant products are available that can be packed into and around air spaces created when cables (or other system components) pass through openings. Tubes, pipe sections and ovals can be used as the frames to hold cables and the water tight and fire resistant sealants.
This project conducted an evaluation of three types of soft penetration sealing systems to determine their suitability for use on naval platforms in place of the traditional transit block systems. The final project report discusses the evaluation of the selected sealing systems, estimated benefits and savings resulting from their use, and recommendations for future work including the development of general requirements that address sealing system performance and physical attributes.
