Manoeuvring Feasibility Study for an Oil Terminal

  Location : Quebec, Canada  
  Year : 2011  
  Client : Valero  
  Vessel Type : Panamax and Post-Panamax assisted by interactive ASD tugs  
  Ultramar, owned and operated by Valero, has mandated the Maritime Simulation and Resource Centre (MSRC) in order to validate the prospect of docking larger ships at section 86 of its Saint-Romuald tanker terminal. To this end, MSRC has conducted a series of simulated manœuvres with two interactive ASD Tugs.
The objective of the simulated manœuvres was to determine if section 86 would allow Panamax and Post-Panamax type of ships to safely dock within wind and current operational limits at that particular dock. The choice of ships, in terms of  dimensions and tonnage, was established under criteria identified by Ultramar.

A total of seven simulated exercises were carried out. Two types of ships were used, with the assistance of two 60 ton bollard pull Z-Drive tug boats. All the simulations took place at the beginning of ebb, i.e., 90 minutes following high water time in Québec, with variable winds from 10 to 30 knots.
