Statoil and project supplier Teamtrade standardized on the use of Hoke Gyrolok compression fittings, instrument valves and manifolds in materials including 316 stainless steel, Duplex, Titanium and Hastelloy.
   In fact, Teamtrade has never before delivered as broad a range of Hoke products to a single project. This included needle, ball, check, rising stem plug, and bleed valves.
   There were also 2-valve and 5-valve instrument manifolds in both 6,000 and 10,000 psi configurations and with both metal and soft stem tips for liquid and gas service, 8-way air distribution manifolds and sampling cylinders.
   Gyrolok fittings were supplied in sizes from 6mm to 25mm, along with matching Gyrogages which aid safe installation of the fittings by preventing the possibility of any installation errors.
   The Hoke equipment was delivered to a variety of applications on this huge project, such as high pressure and high temperature hydrocarbon and process systems, control valves and hydraulic systems and power units.

   Other application areas included compressors and turbines, chemical injection and methanol packages, air supply, ballasting and cargo systems, subsea systems and xmas trees.
   With oil flowing since Spring ’99 and gas coming on-line this year, Teamtrade has highlighted long cycle life and savings in maintenance costs as main benefits of the Hoke products, plus competitive price and delivery terms.
   Easy installation and assembly procedures were additional advantages, and storage costs have also been reduced by the ability to select the correct material relevant to critical applications and limiting the variety and numbers of components needed.
   The Hoke valves and fittings were specified for the working life of the field after evaluation of their performance on the Norne production vessel. Selection demands included
high pressure and temperature, corrosion resistance and meeting NACE requirements.
