Hull fouling causes drag-related speed loss and increased fuel consumption when more power is delivered in order to maintain ship schedules. Hull fouling is also a topic of growing environmental concern and international regulation as it relates to green house gas emissions and the carriage of aquatic invasive species on fouled hulls. To combat these issues, shipping companies are relying on modern hull coating systems like foul-release paint to provide a ready solution. Foul-release and most other types of marine hull paint are expensive and shipping companies have had few easy choices for accurately measuring paint performance and cost effectiveness before making fleet purchasing decisions.
