The Netherlands, 19 November 2014 – Cooperation between three companies developing innovative solutions for deepwater installation has led to the introduction of a new system capable of handling heavy loads at depths of well over three kilometers.
The companies involved are Deep Tek, which provides a wide range of services to the oil and gas, salvage, scientific research and deep water mining sectors; Lankhorst Ropes, a world leading rope technology innovator and manufacturer of high performance synthetic ropes; and DSM Dyneema, the producer of Dyneema® ultra-high molecular weight polyethylene fiber.
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 optimised 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 outstanding 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.
The system has already found its first commercial success, with two orders placed by Jaya, the leading offshore energy services group that is now part of the Mermaid Marine Group of Companies. Jaya will fit the system to 110-tonne cranes designed by J.J. Offshore for two new 88-m ships.
Deep Tek’s Managing director Moya Crawford says the joint development leverages the three companies’ technological capabilities and expertise, for the benefit of their customers. “It responds to the needs of vessel owners that wish to install higher loads in deeper waters using smaller and more economic vessels than before,” she says. “It also addresses concerns of major oil companies about the rising cost of developing deepwater fields.”
Wilco Stroet, Senior Vice President Maritime, Oil and Gas at Lankhorst Ropes says: “All three partners believe the prospects for the new deepwater lowering system are excellent, and we will all be putting our weight behind the technology to make sure it succeeds in what are very competitive markets around the world.”
The new system is an outstanding example of the integration of world-leading technologies from along the supply chain, and could only be achieved by strong partnership between the parties involved, says Jorn Boesten, Segment Manager Offshore at DSM Dyneema. “Dyneema® fibers have outstanding potential in deepsea environments, and we are very happy to work together with Lankhorst Ropes and Deep Tek to maximize this potential.”
