Circor instrument fittings and valves have helped meet a demanding challenge in the North Sea, with the end-client demand for an extended system life span, by being selected as key components in an air starting system. IPU Group Starting Division supplies a comprehensive range of non-electric starters for some of the harshest environments around the world and recently produced a system to start a diesel 3612 CAT engine delivering essential power to the Kristin North Sea platform off the coast of Norway for Geveke Oil and Gas. Statoil, the platform owners, determined that the whole project should have a minimum life span of 25 years, which created significant challenges in design and sourcing of materials and external suppliers. The IPU solution included a complete system which was fully assembled and ready to use. All pipe work was fully welded to ASME IX and was in 2in stainless steel with instrument fittings and valves supplied by Circor Instrumentation. The system comprised two 500 litre air receivers designed to ASME, U stamped and hot dipped galvanised to provide the required corrosion resistance, and a stainless steel electric control panel. The compressor has a 30 bar outlet pressure and 16.5m3/hr delivery to fill each receiver in less than an hour.
