Safety and Utility system uptime is critical, whether on an Offshore Platform, an FPSO, an LNG terminal or a refinery. Normally supporting the main process as well as other facility systems, with pressures typically in the range of 5-10bar –  with some significant exceptions such as heating medium and injection systems.

Operators recognize that utility systems are essential for production support, with redundancy often designed into the process layout, and ideally, duplicate equipment such as pumps and heaters or coolers fitted with isolation valves for maintenance. On a major North Sea oil & gas platform, we recently intervened in a situation where leaks were reported in both the primary and backup firewater pump cooling systems. Without suitable isolation valves in place, this safety critical maintenance would mean a production shutdown. The Operator considered plugging and freezing, but recognized that the Izomax AOGV mechanical isolation tool was the only system that would allow full corrective maintenance without a production shutdown.

Whether a small diameter pressurized air system for instrumentation, safety critical firewater systems or a 36” valve on a flare tip, the AOGV mechanical isolation tool has the proven capability to meet the challenge
