In environments where connectors and cables are exposed to high pressures and submerged in water for extended periods, secure and waterproof electrical connections are vital for ensuring that installations can be easily assembled, modified and maintained.
This is especially true for remotely operated vehicles or ROVs. These subsea robots connect to ships with data and control cables, which allow for remote control of the vehicle.
To ensure these connections, one of the largest manufacturers of ROVs tasked engineers at Bulgin to develop an environmentally sealed connector that combined quick and easy connectivity with long-term corrosion resistance.
The Bulgin Tether Connector allows data, fiber optics and power signals to be sent to the ROV, said Mark Berry, Product Line Programme Manager for Bulgin.
The 316 stainless-steel design allows ROVs to operate at the high pressures and extreme temperatures found at depths of up to 7,000 m below sea level, Berry added. This is accomplished by using dynamic pressure balancing through free flow of dielectric oil from the surface to the connector.
The ROV Tether Connector is a custom solution that provides a quick yet secure coupling and locking mechanism. It is engineered to prevent problems happening in the first instance, and helps to reduce cable termination time and potential downtime for subsea projects. It is rated for 5 KV and 32 A.
