PU bend restrictors from Trelleborg specified for deepwater field in Brazil

James Harrison, Key Account Manager within Trelleborg Offshore & Construction, said: "Securing this contract is another major achievement in an important growth region for Trelleborg. As well as recently opening a new manufacturing facility in the heart of Brazil's oil and gas community, Macaé, steel restrictors have been the status quo for riser projects in offshore Brazil for many years and having our proven polyurethane technology adopted for a major contract in the area is very encouraging.” "Our solutions have an unrivalled track record and reputation across the globe and we are confident we will continue to see increasing demand from traditional ‘steel' regions. Particularly as our new state-of-the-art facility is enabling us to locally develop, manufacture and supply the same high-performance thermal insulation and buoyancy solutions currently being offered to our global customers, in turn bringing us closer to the action and our customer base in Brazil,” he said.[image_0]Trelleborg was awarded the contract by leading flexible pipe manufacturer, NOV Flexibles, following the successful completion of the project to provide 83 polyurethane bend stiffeners for 6 and 4 inch / 15 and 10 cm dynamic risers in the first phases of the project, which took place over the last twelve months.According to Trelleborg, using polyurethane restrictors brings a number of significant benefits when compared with steel. Installation and maintenance of the assembly is less time-consuming and more cost-effective, with significantly lower whole life cost, as plastic does not corrode or have to be protected using platings, paint and anodes. It also has a greatly reduced weight, making it neutrally buoyant in water. This means there is considerably less stress applied to the flowline and adjacent parts of the subsea structure during both installation and service.All the solutions will be tested in accordance with Norsok, DNV and customer specific standards. Delivery of the products is expected in June 2013.To prevent pipes from overbending at the interface between flexible and rigid structures, bending restrictors are often installed. Trelleborg's bend restrictors are made up of a number of interlocking elements which react when subjected to an external load, locking together to form a smooth curved radius. This radius is chosen to be equal to or greater than the minimum bend radius of the pipe that it is applied to. Once the elements have locked together, the bending moment present is transferred into the elements and back through a specially designed steel interface structure into the adjacent rigid connection, therefore protecting the pipe from potentially damaging loads.The P-58 FPSO, which operates on the Baleia Azul field in the Parque das Baleias area, north of the Campos Basin, is moored 48 miles / 78 km offshore in a water depth of 4,593 feet / 1,400 meters, and is expected to last for 25 years. Oil production comes from 19 satellite wells connected individually to the unit and is expected to commence during the first quarter of 2014.Officially opened in September 2012, Trelleborg's new facility in Brazil is located in the coastal city of Macaé, which is approximately 112 miles / 180 kilometers north of Rio de Janeiro. It develops, manufactures and supplies Trelleborg's complete offshore product portfolio, including a wide range of high performance polymer-based solutions for offshore topside and subsea oil and gas exploration, such as insulation tape and buoyancy products. To support offshore customers in their quest to reach greater subsea depths, the new 7,000 m2 / 75,347 square feet facility boasts one of the largest hydrostatic pressure testing vessel in the world.
