Experiences from the offshore installation of a composite materials firewater system
- Amoco Norway Oil Co., Stavanger (Norway). Production Dept.
A prototype 300 m composite dry deluge firewater system was installed in December 1991 at the Valhall Field in the southern North Sea Norwegian offshore sector. This installation followed successful safety verification of the explosion and fire resistant design concept consisting of glass-fiber reinforced epoxy (GRE) piping components protected with a reinforced intumescent epoxy fire insulation. The installation was based primarily on the use of prefabricated GRE piping spools and fire insulation cast onto the piping or applied in the form of cast half shells. Significant experiences gained from the project are described. These experiences involve pre-engineering activities, detailed engineering, onshore fabrication, shipping, offshore hook-up, quality assurance, safety and economics. Although the overall installation was successful and the system is functioning as intended, areas of possible optimization and cost reduction for future composite firewater systems were identified. These findings are also briefly reviewed.
