Parker's ability to supply complete instrumentation assembly packages to the Sn°hvit Group's engineering, procurement and construction manager, Linde, fitted with anti-freeze heating systems to combat the harsh environmental conditions - were key factors in winning the contract. The systems will provide the process instrumentation required for Linde's ground-breaking, energy-efficient, liquefaction plant.
Parker is supplying all the manifolds, valves, tube fittings and tubing components required for the onshore LNG plant. In total, Parker expects to supply around 1000 H-Series manifolds, over 20km of conventional and heat-trace tubing, and several thousand twin-ferrule A-LOK compression tube fittings. In addition to standard 316 stainless steel fittings, Parker is supplying fittings fabricated from 6Mo (6% molybdenum steel) for certain corrosion-prone areas of the process - such as the seawater cooling systems.
To further protect against corrosion, all the tube fittings will be treated using the company's proprietary Suparcase process. This hardens the back ferrule - the part of the fitting responsible for ensuring a strong grip on the tube - without adversely impacting susceptibility to corrosion. It avoids leaving the avenues for the onset of corrosion that can be caused by conventional hardening techniques.
Parker's instrument enclosures for the Sn°hvit project will be fitted with high performance heating elements and insulated to ensure the integrity of the measurement systems. They will operate down to -25°C, an essential feature for the Melk°ya location which - at above 70°N - is well inside the Arctic Circle.
