Dyneema for Modu Mooring Lines In Brazil

The Netherlands, April 27, 2011 - 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. SK78 grade fiber was developed specifically for this type of mooring application and although it has a proven track record of success in Asia, US and European waters, the Petrobras order marks the first time they will be used for MODU mooring in Brazil. Petrobras is expected to use eight mooring ropes made with Dyneema® SK78 fiber on a MODU in its new Pre-Salt deepwater fields off the Southeastern coast of Brazil, site of one of the largest recent oil discoveries in the Western Hemisphere. Petrobras plans to start using the ropes around mid-year. Petrobras has chosen to use ropes made with Dyneema® over polyester because of the lower weight and greater ease of handling. Polyester ropes with the same mechanical properties weigh around three times as much and are almost twice as thick as ropes made with Dyneema®. Steel ropes would weigh around seven times more than ropes made with Dyneema® fiber

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

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

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

Plateena Rope Makes a Difference for India's Fishermen

India's Garware-Wall Ropes introduce Plateena rope composed of Dyneema®, the world’s strongest fiber™, made by DSM A leading cordage manufacturing company in India, Garware-Wall Ropes Ltd., is a household name in the fishing community through its close bond with Indian fishermen. During extensive trials, the benefits of Dyneema® became clear when in 2011, the fishing vessel “Srinivasa” was trialing the new Plateena rope warp lines in heavy currents

LNG Mooring Lines Made with Dyneema

Safer and Stronger than Steel   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

DSM Gets Favorable Judgment in Trademark Lawsuit

The United States District Court for the Northern District of Texas concluded a judgment for patent and trademark infringement and related claims against Armor , on April 22, 2008. The judgment relates to DSM’s super strong polyethylene fiber Dyneema. With this judgment DSM was able to stop Armor from selling infringing products comprising polyethylene fiber on the market Armor is a based company with manufacturing operations in

Samson Brings ML-12 to Utility Rope Market

Samson, specialist in performance cordage, is launching Samson’s newest 12-strand stringing line, incorporating Innegra-S fiber. ML-12 is Samson’s newest 12-strand stringing line, blending Innegra-S, a high modulus polypropylene (HMPP), and Dyneema, a high modulus polyethylene (HMPE).

Dyneema Slings Transport Turbines

Use of Dyneema ultra-high molecular weight polyethylene (UHMWPE) fiber is helping to ensure that a major construction project to bring clean energy to millions of people in the U.K. moves ahead as efficiently and safely as possible. The world’s largest offshore wind farm is under construction in the North Sea, 23 km off the coast of England. Scheduled for completion in 2012, the Greater Gabbard wind farm’s 140 turbines will generate 500 megawatts of electricity for the people of

Samson Awarded 11th Patent

Samson was awarded a patent titled Line Structure for Marine Use in Contaminated Environments. This technology was developed by Samson while partnering with Delmar Systems on its patented Omni-Max gravity-installed anchor system. Proper deployment of the new anchor design would have been hampered by the use of traditional anchor chain in this application. The additional weight of chain affects the trajectory of the anchor causing insufficient embedment into the seabed
