Transits of Post-Panamax Ships on the St. Lawrence Waterway


  Location : St. Lawrence Waterway  
  Year : 2009  
  Client : Port of Montreal, Transport Canada, Canadian Coast Guard and the Laurentian Pilotage Authority  
  Vessel Type : Post-Panamax  
 

The Maritime Simulation and Resource Centre (MSRC) is located in Quebec City and is equipped with a state-of-the-art Kongsberg full mission bridge simulator. Furthermore, it has several bridges, making it possible to conduct interactive simulations.
The purpose of the simulations conducted during this study was chiefly to determine the operating limits of post-Panamax ships in a channel in the St. Lawrence 245 m wide, that is:

  • wind limits;
  • effect of the current;
  • interaction between two post-Panamax ships when meeting in a channel 245 m wide;
  • interaction between a post-Panamax ship and another type of ship when meeting in a channel 245 m wide;
  • interaction between two post-Panamax ships when one is overtaking the other in a channel 245 m wide;
  • interaction between a post-Panamax ship and another type of ship when one is overtaking the other in a channel 245 m wide.

Sectors between Quebec City and Montreal were selected to conduct simulation tests in view of their potentially higher risk levels. These sectors, however, are representative of the entire piloting district. They also have such important characteristics as frequent significant heading changes, strong currents and a channel 245 m wide lying between two areas of shallow water.

The simulations took place in two phases. First, for three days, fast-time simulations were carried out to determine the operational limits of these types of ships, especially in strong winds. Next, real-time simulations with interaction were carried out using two bridges to simulate the ships encountering or overtaking each other. In each booth, the manoeuvres were carried out by two Grade A pilots from the Corporation of the Central St. Lawrence Pilots, thus replicating the actual piloting conditions of the type of ship.
