Connectors

A Hybrid Wetmate Connector on the HD Camera
Cable Termination Assembly

A cable termination assembly (CTA) is removed from the cable drum that was just released from the Remotely Operated Cable Laying System (ROCLS) during the ROV ROPOS dive 1599. The CTA, held in ROPOS's manipulator, provides a termination/connection between wetmate connectors and extension cables. An RSN wetmate hybrid connector (RS03W3-PA) is shown in the background, still attached to an extension cable that is figure 8'ed on the front horns of the cable drum.

Deploying Cables for High-Definition Video Camera

This 60-m extension cable will soon host a high-definition video camera to be deployed at the Mushroom hydrothermal vent (far left). White microbial mats along narrow fractures in the lobate lava flows mark areas where low-temperature diffuse hydrothermal fluids issue from the seafloor. The 7-function manipulator arms of the Canadian ROV ROPOS gently place the wet-mate connector holding plate on the seafloor. VISIONS '13 Leg 4

Connectors and splices (Cable Termination Adapters, CTAs) are critical components in the extension cable assemblies because they provide terminations between cables, junction boxes, platforms and nodes. Several types of connectors are necessary for the RSN cabled system. Most of the cables are wet-mate connectors that allow coupling and uncoupling of cables with an ROV without having to bring infrastructure to the surface. This allows optimal use of ship and ROV time while at sea, and provides valuable testing capabilities. Connectors for each part of the RSN have been carefully evaluated. In general, there are three major types of connectors: Wet-Mate Electrical Connectors, Wet-Mate Hybrid Connectors, and Dry-Mate Electrical Connectors.
