Cortland Company, the global designer and manufacturer of engineered synthetic ropes, heavy lift slings, electro-optical-mechanical cables, and umbilicals is working with Dutch Heavy Lift Consultancy on DONG Energy Anholt Offshore Wind Farm project to deliver custom Plasma® HMPE for towing monopiles.
Anholt Offshore Wind Farm will be Denmark’s largest offshore wind farm with 111 wind turbines. Construction is currently taking place between Djursland and the island of Anholt in the Kattegat, due to be completed in 2013.
Monopiles are towed into place using Cortland’s 44mm diameter Plasma® rope. The rope is connected to the towing beam, wrapped around the trunnion at its half waypoint, before being looped back. The automatic release system allows the tug to easily disconnect from the monopiles.
Cortland’s Plasma® rope has built a loyal following in the Tug/Salvage and Offshore world. Many modern tractor tugs, especially those with render-recovery winches, consider Plasma® rope as a stable necessary towline or pennant for safe and efficient operations. With the addition of its large Herzog 2000 braider in its Anacortes, WA USA mill, Cortland can now build twelve strand-braided ropes up to 200mm diameter. For large horsepower tugs, OSVs and offshore vessels, the lightweight, high strength, low stretch and durability of large diameter Plasma® ropes in long lengths is highly desirable.
Cortland provides accurate performance data necessary for complex marine projects including product linear density, elongation, outside diameter, compaction rates, breaking strengths. Cortland’s ability to offer factory authorized fabricated splice terminations in key global locations also provides a key benefit; US, GoM, Singapore, Australia, Europe and Middle East.
Rob Arends, Cortland’s European Sales Manager, said. “Plasma® 12×12 rope was chosen for its balanced construction and firm shape. While fitted in to the special developed connector our Plasma® rope behavior matched the requirement perfectly and needed no protection what so ever”.
