We were invited to the platform for an initial survey regarding the future integration, reliability & longevity of their WHRU and associated control isolation dampers. Although the existing WHRU and casings were serviceable the inlet, bypass & isolating dampers, and controls, needed a complete overhaul. Due to previous safety issues, the operators had lost confidence in the original arrangement & new dampers were therefore requested. However, since the dampers were an integral part of the WHRU, the whole WHRU had to be changed.

We were invited to the platform to investigate operational WHRU diverter problems, It was apparent the Flap type diverter was not suitable for the application that it was being used for, ie, controlling low amounts of exhaust gas through the WHRU.

We were invited to the FPSO to investigate operational WHRU diverter problems. It was apparent that the existing Diverter manufacturer had ceased trading and was untraceable. However, our recommendations were for complete overhauls of both units.
