Main Bell Umbilicals

Main Bell Umbilicals Photo

Cortland’s umbilicals can be built to a customer's exact requirement for main bell, wet bell, habitat, and welding system end use. Our Fibroflex hoses and cables and our standard or custom cable designs can be incorporated to provide services for gas, hot water, gas reclaim, depth monitoring, power supply, signal, video transmission, and communications.

These components can be laid up in a helical format with the addition of fibre or strength rope filler elements and can be manufactured with either a polyethylene monofilament overbraid or an extruded thermoplastic outer sheath. Various hose end fitting, electrical connectors, 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 are available to all main industry standards including Lloyds Register of Shipping (LRS), Det Norske Veritas (DNV), and American Bureau of Shipping (ABS).
