Underwater-mateable connectors have enabled under- water industries to build modular components for subsea use. In particular, these wet-mate technologies have allowed subsea systems to be assembled on the sea? oor.

This has allowed the user to maximize modular system size and weight within the constraints of their installation equipment whilst, once installed subsea, still able to con- nect these modules to use interconnected and distributed communication, control and monitoring systems. A major consideration in the selection of underwater-mateable connectors is the intended mode of operation of that prod- uct with reference to it’s speci? cation and hence cost.

Underwater-mateable connectors are used for joining up electrical or optical circuits underwater. They provide a termination of an underwater cable or oil-? lled hose, containing electrical conductors or optical ? bers or both.

This allows divers, Remotely Operated Vehicles (ROV’s),

Autonomous Underwater Vehicles (AUV’s) or automatic connection systems, to facilitate the connection of the two halves underwater. The impact of being able to do this has enabled signi? cant progress in the modulariza- tion of underwater systems in the oil and gas, defense and oceanographic industries, allowing the following: • Modular sub-systems to be installed underwater, one at a time, and then later interconnected together to distrib- ute power and communications, forming larger underwa- ter systems • Facilities to include ports for diagnostic maintenance
