Terminal efficiencyMoving cargo through VancouverÔÇÖs largest container terminal company can be a balancing act, Morley Strachan explains to Gary Toushek. TSI Terminal Systems Inc. began as a stevedoring company on a small wharf in the Vancouver, British Columbia harbor more than a century ago, and today the company operates two major terminals, Vanterm and Deltaport. Between these two terminals, TSI handles nearly two million TEUs (twenty-foot equivalent units, i.e., large shipping containers) of cargo every year.
