Importance of Dynamic Routing Algorithms and Event Management Tools in Terms of Maritime Safety and Operational Efficiency

The accurate knowledge of ocean weather forecasts and oceanographic data, along with their associated risks, is a significant challenge that requires constant questioning and monitoring of the disseminated information. Ship’s routing has always played a crucial role in the maritime industry. As the maritime sector has grown, accompanied by numerous regulations, technical constraints, and environmental restrictions, operational precision has become more important than ever for managing ships efficiently and safely. To achieve this, ocean modeling and operational forecasting are key elements for establishing high-resolution meteorological and oceanographic databases. Additionally, advances in the IT sector enable the use of routing algorithms that, with the latest gathered meteorological and oceanographic data, provide optimal routing options for ships in terms of safety and efficiency. Once the voyage begins, these algorithms continue to analyze recent weather developments and suggest adjustments based on the most convenient options. Meanwhile, the algorithms support the analysis of resonance risks (parametric and synchronous rolling), to which large ships are particularly vulnerable, and predict fuel consumption with high accuracy under any weather conditions while computing the necessary RPM to maintain constant power. To ensure proper follow-up on safety and operational parameters, an event management tool monitors operational indicators and generates alerts, often called "Events." In traditional routing, distance is one of the most important factors in choosing the optimal route, while oceanographic and weather data are considered more for safety than for efficiency. Once chosen, the route is changed only if safety conditions significantly deteriorate due to weather changes or an emergency. This paper demonstrates actual savings by using dynamic routing algorithms on a large fleet of container ships in worldwide trade compared to traditional routing and maximizing the benefits of oceanographic and weather impact on the ship’s efficiency. Oversight and support are carried out from navigation centers ashore, thereby enhancing safety and operational efficiency. Within established parameters, alerts are automatically prioritized and addressed by the event management system, providing operators with clear insight into the current situation across the fleet and enabling prompt resolution of specific issues. Comparative analysis of data from various cases along the fleet suggests that the traditional “shortest distance” routing is no longer the most efficient operational approach, while dynamic routing significantly reduces the ship’s exposure to adverse weather and maximizes the benefits of currents and wind effects, resulting in better operational efficiency and less fuel consumption. Alongside advances in ocean modeling and operational forecasting, the development of smart shipping and detailed operational profiles of the ships is essential for enabling shore-based support and oversight; unfortunately, it’s still barely implemented among most shipping companies.
