Main Services Umbilicals

Cortland's Main Services Umbilicals can be built to customer requirements for Main Bell, Wet Bell, Habitat and Welding system end use. Hoses and cables are incorporated to provide services for gas, hot water, gas reclaim, depth monitoring, power supply, signal, video transmission and communications.

Laid up in a helical format, components and required strength members are protected with either a polyethylene monofilament overbraid or extruded thermoplastic sheath. Various hose end fitting, electrical connector and mechanical termination options are available to suit specific requirements.

For your peace of mind, all design, manufacture, testing and termination is undertaken in-house to our proven high standards. Third party approval and the required back-up certification and documentation is available to all main industry standards including Lloyds Register of Shipping (LRS), Det Norske Veritas (DNV), American Bureau of Shipping (ABS) and International Marine Contractors Association (IMCA).

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. Fibroline and Fibrolite hoses have a smooth polyurethane cover for excellent abrasion resistance, while giving 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 comms cable offers an inherent fiber 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, mechanical terminations - including “D”-rings and shackles - are available to meet specific requirements.
