Connecting to High Power Underwater

A 12 pin electrical wet-mate connector on a junction box at the base of Axial Seamount awaits its mate during turning of the platforms and instruments at this site. The oil-filled mates, allow the ROV to disconnect and connect extension cables on platforms, junction boxes, and instruments without bringing the entire assembly to the surface. They are used heavily on our system to reduce operations and maintenance costs. Credit: UW/OOI-NSF/WHOI, DIve J907, V16.
