Economics of Dyneema-based Ropes
Traditionally thought an expensive alternative to traditional steel wire and conventional polyester-based synthetic ropes, offshore ropes and mooring systems made with Dyneema have been making inroads. End users such as ConocoPhillips, Shell and Petrobras are working with systems based on the high-strength, low-weight fiber of DSM Dyneema. Coupled with their durability and longevity, these rope systems are increasingly recognized for a variety of performance and user benefits that ultimately save on the bottom line.
Lankofirst Debuts Fiber Rope Connector for Deepwater Mooring
Lankhorst Ropes Offshore Division (LROD) announced the latest results of offshore trials of its Lankofirst synthetic fiber rope mooring connector on booth 1517 at OTC 2013. The trials have shown a significant reduction in mooring line deployment times and improvements in health and safety using the Lankofirst connector, compared with traditional mooring line plate links and thimbles. The Lankhorst booth will also feature the ultra-low creep HMPE mooring rope made with Dyneema for permanent deepwater moorings beyond 2…
LNG Mooring Lines Made with Dyneema
The introduction of new and larger vessels, Q-Flex and Q-Max, and new, often more exposed terminals becoming operational have changed mooring dynamics. The need to maintain workers’ safety at all times, whilst delivering maximum operational efficiency through lower costs and faster turnaround times remains unchanged. DSM Dyneema, a close partner to the LNG industry, has done a study which concludes that these industry trends are changing the performance demands for LNG mooring lines.
Dyneema: Making Light Work of Ultra-Deep Sea Recovery Operation
A salvage operation on a ship wreck 3200 meters below the surface of the South Atlantic has been successfully carried out thanks to the use of lightweight ropes made with Dyneema ultra-high molecular weight polyethylene fiber. Dyneema fiber, the world’s strongest fiber, is manufactured by DSM Dyneema. It is used by Hampidjan, one of the largest fishing gear and “super rope” manufacturers in the world, to make Dynex Warp, an advanced patent-pending winch line for deep sea lifting and lowering as well as for towing fishing trawls.
Dyneema for Modu Mooring Lines In Brazil
Brazilian oil giant Petrobras has specified ultra strong, lightweight Dyneema fibers for a complete set of mooring ropes for a semi-submersible mobile offshore drilling unit (MODU). Headquartered in Rio de Janeiro, Petrobras has substantial interests in deepwater exploration. Petrobras specifically asked for the ropes to be made with SK78 grade of UHMWPE (ultra high molecular weight polyethylene) fibers from DSM Dyneema for its high strength at low weight properties.
Samson Rope, SWOS Team for Heavy Lift
Samson high-performance synthetic slings helped Technip install subsea hardware at Petrobras’ Cascade & Chinook project. Installing two pumping stations and two manifolds at Petrobras’s Cascade and Chinook fields in the Gulf of Mexico at depths in excess of 2,500m was accomplished with a “wet handshake” and the assistance of Samson’s AmSteel-Blue fabricated into lifting slings for the operation. Technip was the contractor, and Deep Blue was the installation vessel used during the deepwater installation.
Petrobras Awards Lankhorst Ropes Dyneema Deepwater Mooring Line Contract
Leading deepwater rope manufacturer, Lankhorst Ropes, has secured the first-ever, worldwide order for Dyneema synthetic mooring rope for deepwater MODU (Mobile Operating Drilling Unit) projects from Brazilian oil and gas producer Petroleo Brasileiro SA (Petrobras). Gama 98 is a rope construction developed by Lankhorst Ropes specifically for deepwater mooring, and used on a number of major deepwater projects in the Gulf of Mexico. The rope will feature up to 12 Dyneema SK78 yarn sub-ropes. Developed by DSM, Dyneema SK78 is a high modulus polyethylene fibre.
Large Diameter Synthetic Certified by Lloyd's
Samson, provider of performance cordage, and Endenburg BV, Samson’s Master Fabricating Distributor in Europe, has provided Seaway Heavy Lifting (SHL) with the first very large diameter synthetic rope slings certified by Lloyd’s for offshore installations. The two lifting systems, made from 144-mm diameter AmSteel-Blue, Samson’s rope made with 100% Dyneema high modulus polyethylene fiber, are currently assisting in the installation of 140 turbine foundation monopiles as a part of the North Sea’s Greater Gabbard project, the largest wind farm currently under construction.
Offshore Windmill Uses Dyneema Fiber
For the installation of offshore wind farms in the Irish Sea, Mammoet Van Oord, a marine contractor, selected heavy lifting slings made with Dyneema polyethylene fiber from DSM Dyneema. The round slings, manufactured by the Unitex Group, are designed to lift heavy loads weighing up to several hundreds of tons. Mammoet Van Oord is using the Unitex lifting slings with its new jack-up installation barge, the “Jumping Jack,” to place 240 ton monopiles as part of the foundations…
