Hefring Marine has launched a new Impact Report feature for its Intelligent Marine Assistance System (IMAS), offering visibility into vessel impact events and their potential effects on safety and performance.
The new functionality provides visual summaries of incidents based on sensor data collected during operations. The system analyses impact direction, type, and location on board, combining data from IMAS sensors with other sources such as engine performance readings to support post-incident reviews.
“Traditional impact analysis has been limited to basic accelerometer readings that miss critical context,” said Karl Birgir Björnsson, CEO and co-founder at Hefring Marine.
“Our Impact Report feature goes far beyond simple magnitude measurements. It analyses each impact to determine hull location, impact type, and can automatically flag various scenarios including propeller strikes, grounding events, and potential collisions.”
The new report includes an overview of IMAS sensor performance during each voyage, identifying the number and intensity of recorded events and highlighting the parts of the vessel exposed to the highest forces.
Impacts are visualised using side and top-down diagrams to show vertical and lateral movements, and events are plotted on a timeline with interactive drill-down options.
For each impact, the system provides metrics including force duration, directional vectors, location mapping, and automated detection of likely causes such as propeller ventilation or nearby vessel activity. Each event also includes a charted impact profile and per-sensor analysis.
The Impact Report is available to existing customers and is included in new IMAS installations without requiring additional hardware.
