The St. Lawrence Seaway’s Voyage Information System: The next step in vessel traffic management

In the St. Lawrence Seaway, an initiative is underway to revamp the Seaway’s vessel Traffic Management System (TMS) by developing a new Voyage Information System (VIS) to better manage vessel transits through the international waterway. The two entities responsible for overseeing the Seaway are the Canadian St. Lawrence Seaway Management Corporation (SLSMC) and the U.S. Great Lakes St. Lawrence Seaway Development Corporation (GLS). While the initial goal of the VIS project is to improve the safety and efficiency of Seaway transits, the Seaway corporations want to ensure that the modernized Seaway TMS can align with efforts by other stakeholders to improve vessel traffic management throughout the entire Great Lakes-St. Lawrence River Seaway System. The VIS would have the ability to gather and process data that could provide recommendations for real-time course or speed changes to safely facilitate maximum operational efficiency. This includes scheduling vessel inspections, bridge closures, pilotage services, and dock usage at ports, as well as lockages, while respecting the interests of individual vessels.
