In June 2011, the UIE Inspection Team Norway together with the vendor Linjebygg Offshore AS (NO) and sub vendor Wälischmiller Engineering GmbH (GE) performed a pilot test of two remote inspection systems carrying a video camera and a video probe. The information obtained was of sufficient quality to assess the integrity and state of a clean gas scrubber.
Early May 2012, four other gas scrubbers were inspected during plant shut-down after a successful upgrading of the tools and equipment as derived from the pilot test. Furthermore familiarization and training were done utilizing mock-ups. Results showed that substantial volume of work, including a high degree of hazards, were avoided, and costs were reduced. Production deferral (SD period) were reduced by a numbers of days.
