Geo Oceans and Vertech demonstrated the capabilities of the ROV system for cleaning and maintenance services on an offshore FPSO. The hull was heavily fouled, so physically attaching the ROV system to the hull was required to provide a stable platform for cleaning. The ROV vessel inspection system included hull attachment tools for stabilisation, HP and mechanical cleaning tools, such as scrapers and brushes, CP and UT sensors, sonar for navigation, laser profiler, and caliper tools for chain link measurements.
