DSM Dyneema Unveils Black Dyneema

Dyneema-branded ultra high molecular weight polyethylene fiber is now available in black. DSM Dyneema, the developer and producer of Black Dyneema, says the new product will open up important new opportunities for the Dyneema fiber family. According to the developer, Dyneema is the world’s strongest fiber on a weight for weight basis and is already used for a broad range of applications. Until now, Dyneema fiber has only been available in its natural white color. If users wanted to use the fiber in an application requiring color, they needed to post-treat it. But UHMWPE fibers are almost inert chemically, so the colors, which are only on the surface, tend to wear off.

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. SK78 grade…

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 required for the installation of wind turbines in the Burbo offshore wind farm project located off the coast of Liverpool, United Kingdom. Similarly, while abrasive steel wire can scratch coatings that provide important corrosion resistance to the monopiles…

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. In parallel to DSM Dyneema’s investigation, in 2011 members of the LNG community created a Users Group to further investigate HMPE mooring line failures which TTI (UK) was asked to facilitate. DSM Dyneema is part of the Users Group, while at the same time continuing its own investigation program.

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). This blend of fibers gives ML-12 performance characteristics between traditional polyesters and high-performance 100% Dyneema stringing lines. “We knew we had to consider fibers that were unfamiliar to the rope industry in order to achieve our goals,” said vice president of research and development, Dr. Rafael Chou. “Historically, if you wanted a fiber that would out perform traditional nylon and polyester, you had to leap into high-performance fibers like HMPE, LCP, and aramids.

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. To address this issue, Samson engineers developed a synthetic alternative that replaces the anchor chain. One of the biggest challenges in this application was protection of the synthetic rope from the damaging effects of outside contaminants it comes in contact with during use.

DSM Dyneema to Appeal Patent Case Ruling

DSM will appeal against a ruling by a judge in the Court of Milan that one of its Patents is not valid, the company announced in a press release today. According to DSM, the court case dates back to 2009 and was brought by DSM against EOS, a distributor based in Italy and Zhong Fang (also known as Beijing Tongyizhong), a Chinese based manufacturer of UHMWPE fibers. The allegation against both companies was that its fiber, mainly intended for use in rope applications, has infringed DSM’s patent number EP1126052. A patent expert appointed by the judge argued that the patent obtained by DSM was not valid. DSM appointed an independent patent expert to review the evidence. His conclusion was that the patent is valid.

Rope & Wires: At the Forefront of Technology

It hasn’t been too long since industry icon Tom Crowley, Jr. offered that the one technology that had the biggest impact on the safety and efficiency of [his company’s] maritime operations was, in a word: ROPE. The reasoning was simple. Today’s lighter, stronger synthetic strands have gone a long way in helping to reduce back and other related lifting injuries on deck. He stands by that answer today. So does Teufelberger, especially when it comes to the innovative products that they bring to the waterfront today.

A Step Forward for Warship USVs

Unmanned Surface Vehicles (USVs), or seagoing drones, have come a step closer to reality following successful tests of a recovery system. Global navies want to use Unmanned Surface Vehicles. They will keep boat crews out of high risk environments and extend the outreach of surface vessels. There are already forty prototype USVs on the market globally, ranging from 1-10 metric tons in weight. But most research and development in this area is focused on the USV itself. Until now there were no proven systems for launch and, more importantly, recovery of the USV from a mother ship.

AHTS Pulls it Weight on Lankhorst LankoForce Rope

Italian company Rosetti Marino tests its new 220-mt bollard pull Anchor Handling, Tug, Supply & Service Vessel (AHTS). Since 2010, bollard pull testing has become standard practice for newly built steel tugs. The test provides a good measure of the tugboat’s maximum pulling load. Contacted to supply a bollard pull test rope at short notice, Lankhorst supplied a 88 mm diameter, 300 m LankoForce rope made from high modulus polyethylene (HMPE) Dyneema.
