Construction of a deep water marine terminal at Port-Daniel-Gascons, Gaspésie

Located on the banks of the Gulf of Saint Lawrence in Baie-des-Chaleurs, Gaspésie, this large-scale project presented major challenges related to sustainable development, the environment and weather conditions.

This ambitious project was in response to the need for Strudes and McInnis Cement to ship bulk cement along the east coast of the United States.

The project involved construction of a marine terminal serving the cement plant located on the banks of Baie-des-Chaleurs. The terminal comprises a dock for the berthing of 60,000-t bulk carriers and a conveyer gallery to enable the transshipment of materials between the vessels and the cement plant.

Measuring 333 m in length, the docking facility comprises 7 berthing dolphins and 2 mooring dolphins interconnected by 10 steel bridges. The dock includes a main platform and a secondary platform for the transshipment of materials, along with a platform for positioning the loading arms of the vessels.

The dock and the 350-m long conveyer gallery required the installation of 103 piles, docking equipment (fenders, ladders, 100-t bollards, etc.) and cathodic protection

Extreme weather conditions

The team took into consideration the impact of climate change, the presence of ice, the harsh saltwater environment and the need to construct a sustainable-quality marine terminal. The specific location of the marine terminal on one of the banks of the Gulf of Saint Lawrence in Baie-des-Chaleurs, Gaspésie, necessitated a number of preparatory studies before conducting the conceptual studies.

Environmental protection and sustainable development

To counteract the phenomenon of excessive corrosion of steel components in a harsh saltwater environment, cathodic protection was added to each pile. In addition, the length of the piles not encased in rock was covered with epoxy paint for marine environments to protect the habitat of marine mammals.
