In 2012, PROGESYS played a major role in the implementation of a maintenance program for the petroleum storage tanks of the Ultramar refinery, one of the largest refineries in Canada.

The Jean Gaulin refinery in St-Romuald processes foreign crude oil carried by tankers to its deep-water port on the St. Lawrence River. With a storage capacity of 8.7 million barrels of crude oil and intermediate and refined products, it can also store liquefied petroleum gas.

PROGESYS’ team experts, in the field of design and repair of tanks, provided high standard services that comply with all API standard requirements. Consequently, the maintenance program that was executed allowed an increased lifespan of the equipment and its auxiliary systems.
