Cooperation between three companies developing solutions for deepwater installation has led to the introduction of a new system capable of handling heavy loads at depths of well over 3 km (1.9 miles), according to a press release.
The companies involved are Deep Tek, Lankhorst Ropes and DSM Dyneema.
Working closely together, the three companies have developed a fully integrated system based on Deep Tek’s drum winch technology for deploying and recovering payloads in even the deepest waters. Deep Tek has developed and patented a spooling pattern that allows multiple layers of synthetic fiber rope to be spooled onto a load bearing winch drum with no risk of cutting in. Lankhorst has created a new rope design with fully optimized fatigue and load-bearing characteristics for use in the deepwater lowering system. This rope is based on DSM Dyneema’s DM20 XBO fiber and a proprietary coating technology.
The new fully integrated and monitored system makes use of a rope condition management system and takes full advantage of Dyneema fiber’s strength, enabling vessel owners to maximize their vessel output by dispensing with the weight of steel wire. It is currently being qualified by classification society DNVGL using Assurance Case methodology, which enables introduction of new technology without relaxing certification requirements.
Two orders for the system have been placed by Jaya. Jaya will fit the system to 110-tonne cranes designed by J.J. Offshore for two new ships.
