Multidisciplinary approach for spray icing modelling and decision support in the Norwegian maritime sector (SPRICE)
Sea spray icing poses a great deal of risk to marine operations in the Arctic offshore water and in cold waters with favourable conditions for spray icing. By developing models and simulation frameworks for prediction of spray-icing rates and severity and by developing risk-informed decision-making frameworks, this project helps decision-makers in the Norwegian maritime sector be equipped with better tools that support spray icing-related decision-making, risk perception, and operational safety.
This project focuses both on spray icing modelling and simulation as well as on risk-informed decision-making and decision analysis for scenarios associated with spray icing risks. This multi-faceted, multi-disciplinary research project offers a novel approach to furthering the current knowledge regarding spray icing, helping to develop a holistic perspective to understanding and meeting spray icing-concerned stakeholder needs. To this aim, we modify and refine existing spray icing models for prediction of spray-icing occurrence, its rate, and severity, and develop a probabilistic framework for long-term forecasting of spray icing climatology. Tabletop exercises will also be conducted to simulate various spray icing scenarios, during which participants are able to use different spray icing-related information to make risk-informed decisions. We will also develop an interactive platform for crowdsourcing field observations and communicating spray icing risk assessments. Spray icing on a boat - Photo: Audun Mathiassen
