Surface Demand Umbilicals (Air Diving)

Whether it’s for civil, commercial, or hazardous end uses, Cortland offers a complete range of diver umbilicals for surface demand. Our Fibroline and Fibrolite hoses have a smooth polyurethane cover for excellent abrasion resistance, while providing superior flexibility. They are also lightweight for easy operation and storage.

Purpose-built hoses and cables (DCS range) are twisted up into “rope like” constructions to provide all communications, video and power requirements. Our DCS0001 communications cable offers an inherent fibre strength braid as the umbilical “lifeline.”

Choose from optional overbraids, with either factory fitted or retrofitted stockings, for added protection. Various hose end fittings, electrical connectors, and mechanical terminations - including “D”-rings and shackles - are available to meet specific requirements.
