Frigates
For over 40 years NOV have been the industry leader in engineering, expert technical services and design consultancy of GRE Piping Systems, FRP composite structures & thermoplastic drainage & civils, providing high performance products with reduced weight & corrosion resistance. Wenco has partnered with NOV for its utmost quality products.
Our expert engineering provides first class solutions, uniting Advanced Design & Advanced manufacturing for prestigious projects across the globe.
NOV in the Fiber Glass Systems Business Unit, was awarded a significant contract by the Aircraft Carrier Alliance, a partnership of several global companies and the UK Ministry of Defence responsible for delivering new aircraft carriers to the UK Royal Navy. The prestigious contract involved supply of corrosion-resistant glass-reinforced epoxy (GRE) pipes and fittings for both Queen Elizabeth-class aircraft carriers, the HMS Queen Elizabeth and HMS Prince of Wales.
NOV installed more than 4.1 km (2.5 miles) of Bondstrand™ GRE pipework, including 2,000 GRE pipe spools, together with bulkhead penetration trims and more than 1314 m2 (4,311 ft2) of phenolic fiberglass-reinforced polymer (FRP) grating for the forward and aft islands and flight deck catwalks, on both vessels. The solution, which builds upon similar installations on the Royal Navy’s Type 45 destroyers and Astute-class submarines, is fully compliant with stringent UK Ministry of Defense technical specifications for use on naval ships.
Ultimately, NOV innovative GRE pipe systems and FRP structures provided significant weight savings for this flagship project, with a combined saving of almost 390 tonnes between the two vessels when compared with metallic alternatives. In addition, NOV advanced composite materials exceed the lifecycle of equivalent metallic piping by providing superior internal and external corrosion resistance.
Marine Piping Systems
Durable and corrosion resistant
Bondstrand GRE piping is highly resistant to corrosion caused by saltwater, chemicals, residues and bacteria. Similarly, it resists external corrosion even in aggressive marine environments.
Lightweight – easy to install
Bondstrand GRE pipe weighs only a quarter that of steel pipe and is easy to install without the need of heavy installation equipment.
Low installation and operating cost
Installation costs of Bondstrand GRE pipe systems are lower than those for carbon steel, resulting in comparable total installed cost when product costs are factored in. Lower operating costs, due to superior hydraulic performance, reducing energy costs, are realised with Bondstrand, Additionally, should system modifications or repairs be necessary, they can be performed without disrupting the vessel operations as not "hot work" (welding) is required.
Wide range of pipe systems
NOV Fiber Glass Systems offers a complete range of pipe systems in a variety of diameters and pressure classes for many differet applications. Pipe systems are available in diameters up to 1000 mm (40 inch) and standard lengths up to 12 m (40 ft.).
No contamination
Bondstrand GRE does not rust or scale and is resistant to marine fouling. These features also contribute to the cost savings and reduced needs for maintenance.
