  • Location : St. Lawrence Estuary, near Tadoussac
  • Year of achievement : 2019 to 2023
  • Services : Commercial diving


Audet & Knight also stands out in submarine services. In this project, the assignment consisted of carrying out an in-water inspection of the lower part of the Prince Shoal Pillar. The team then carried out the inspection and maintenance of the structure to detect all defects likely to affect its capacity, stability, and safety.

The diver inspected the submerged seabed around the perimeter of the pier, the pier foundation, the sheet pile belt, and the body of the structure, known as the shell. Due to the very difficult hydrodynamic and climatic conditions in the Prince Shoal area, the presence of experienced divers in marine works was required. It is important to highlight the performance of the employees in the use of the methods of intervention in submerged works, which are continuously developed and improved.

Audet & Knight’s team is proud to have a diversified field of expertise that allows to carry out this type of project.
