AbstractA Marine Icing Monitoring System (MIMS) has been developed and deployed on a Marine Atlantic ferry and two offshore supply vessels. The MIMS is a visual based technology for monitoring marine icing accumulation on offshore rigs and vessels where icing poses operational and safety hazards. The system consists of a CPU connected to two high-resolution digital cameras that are positioned to view expansive areas, or smaller areas depending on requirements, where icing could occur when environmental conditions are within certain parameters. The system is stand-alone, requiring no maintenance and needing only a standard 110 VAC power source. All components of the system are weatherproofed so that installation can be anywhere on the deck or superstructure of a facility. The computer controls each camera so that pictures are taken at regular intervals (every 12 minutes) and stored on the computer’s large-capacity hard drive. Data are retrieved from the hard drive at the end of the icing season each year. The system has a satellite phone so that it can be checked and controlled from IOT. Thumbnail images can be quickly downloaded to monitor current conditions at the site, and the cameras can be controlled to zoom in or out. Visual data from the system’s deployments are presented along with some discussion of image analysis strategies, including real-time assessment of icing accumulation. Past and on-going development hurdles are also discussed.
