Cygnus Instruments was born in the marine industry, working alongside ship surveyors and commercial divers to this day. Four decades on, this knowledge of the industry and its challenges is second to none. Cygnus is world renowned as the inventor of easy-to-use, highly accurate ultrasonic testing (UT) equipment.
Solution to Scrubber Corrosion
Exhaust Gas Cleaning Systems (EGCS) – more commonly known as “scrubbers” – are installed on thousands of vessels worldwide in order to comply with the IMO 2020 Sulphur Cap. They have not been without some issues, including EGCS corrosion. The wash water from scrubbers, now containing pollutants it has filtered, is acidic and highly corrosive. The effects of the acidic nature of the corrosive scrubber wash water on the integrity of the ship are further aggravated by the high temperatures of exhaust gases. It is now firmly established that the structural integrity of the scrubber and associated pipework (e.g. SOx scrubber discharge water line) need to be regularly checked for signs of corrosion.
Ultrasonic thickness gauging is a simple, cost-effective, and reliable method to proactively engage with a schedule of preventative maintenance on scrubbers. Areas of particular interest and concern for vessels are the scrubber discharge outlet and the overboard pipe.
Cygnus 6+ Pro boasts an array of intuitive features, including three measuring modes, live A-Scan, B-Scan, and Radial... learn more about tackling corrosion and leakage on ships ultrasonically.
