High-Power Electromechanical Cable Connectors for Deep Ocean Applications.
Abstract
There are two basic connector configurations: one for mating underwater (wet) and one for mating in air (dry). Both are designed for 360 kw, 60 Hertz, 4,160/2,400 VAC power at depths to 6,000 feet, with a mechanical breaking strength of 50,000 pounds. The wet connector is capable of repeated underwater mating by divers, remotely operated actuators, or submersibles with manipulators. Increased performance in depth, strength, or power would require a simple extension of the design, although any significant increase in transmission voltage levels would require further development. These connectors were evaluated in a series of pressure-vessel and open-sea tests to depths of 6,000 feet. The final configuration performed with no electrical or mechanical degradation after 33 matings at depth. Sustained immersion and power tests for one year at 600 feet and in the tidal zone confirmed the endurance of the designs. This development is the first demonstration of a capability for underwater mating of major electrical/mechanical components of sea-floor structures. (Modified author abstract)
