YEAR-ROUND OIL TERMINAL IN ICE COVERED WATERS

On the south shore of the St. Lawrence River at St. David de Levis, Quebec, a new refinery is being completed for Golden Eagle Canada Limited. This refinery has a scheduled production of 100,000 barrels per day. An integral part of the refinery is the new marine terminal designed to receive crude oil tankers ranging from 65,000 D.W.T. to 100,000 D.W.T. and to provide terminal facilities for shipping refined products in vessels ranging from 2,500 D.W.T. to 20,000 D.W.T. Minimum water depths at normal low tide are to be 55 feet and 32 feet respectively. This wharf is subjected to severe ice action and is designed to operate on a year-round basis. It was established that the structure must be designed to absorb the impact of very large ice floes. To protect the large tankers moored at the outer berth from damage by large ice floes, ice breaker cells have been placed upstream from the berth, and the alignment of the wharf has been selected so as to provide protection to the stern of these vessels when ice floes move upriver on the flood tide. This leaves collisions by wind driven ice floes as the main danger to the wharf and to the vessels. The wharf is designed to resist impact. The vessels are protected from ice damage by a fender system, which consists of large rubber pneumatic fenders designed to permit the vessel to yield several feet if struck by a glancing blow from large ice floes.
