Commercial Diving

With years of experience in the inshore/offshore construction diving industry, there is no job too big or small for Canadian Marine Contractors.  With the capability to mobilize to remote areas across Canada, we can build new construction projects or repair old failing infrastructure. Let us make your next underwater project worry free. 

• Let us help you with your next marine construction project. 

• With our hydraulic system, we can use a wide assortment of power tools underwater, including chainsaws, drills, impacts, hammer drills and jack hammers with eco-friendly oil. 

• For shallow jobs, we have pneumatic tools to get the job done.

• Concrete Coring holes for concrete hardware to sleeve into is something that can be done precisely and efficiently.

• Dam work involving Installing and sealing stop logs, clearing out trash racks, general video inspections, penstock inspections, Trash rack repairs and replacement  

•  Bridge video/audio inspection and sub-straight mapping. We can shore up damaged concrete and piles using fiberglass and grout.

• In Stream protection mats can to built and installed to mitigate scouring over and under pipelines at stream crossings. 

• Blast holes can be bored and blast caps installed by divers underwater.

• We can build forms or place grout bags in place to pour grout or concrete underwater.

• Installing anchor bolts into rock with epoxy is an easy way to create anchors where gravity anchors wont work.

• Ship inspections, salvage,  anode replacements, anchor recovery, prop cleaning, prop de-fowling, temporary patches and sea chest blanks are some of the services we offer commercial ships.  Keeping your vessel in the water and running. 

• Let us protect your underwater assets with our inspection, maintenance and repair program (IMR).  This ensures your structures are tracked through out their life ensuring the longevity of them is maximized to their full potential.

At Canadian Marine Contractors we strive to push the envelope of what is humanly possible. We do not shy away from complex jobs that involve deep diving. There are multiple ways to go about diving deep depending on depth and job required. 

Nitrox diving can be used for depths between 50ft-110ft for longer bottom times compared to air diving though this has draw backs as it can't be used if the job requires heavy tooling or over exertion of the diver.

Surface Decompression on O2 is a great method used consistently by commercial air divers around the world offshore. It involves using a decompression chamber to do the diver decompression stops in a controlled environment and on O2 instead of air. This cuts down on the decompression time a diver has and allows for a longer bottom time. This method of diving is usually used in depths of 100ft-180ft. 

 Cofferdams play a vital role in construction projects, and at Canadian Marine Contractors, we boast extensive experience in installing a variety of temporary structures. Whether it's robust cellular cofferdams or cost-effective box variants, we possess the expertise to tailor solutions to suit any project. With a fully equipped fabrication shop, we can craft customized cofferdams designed to enhance both efficiency and safety.

Ensuring safety takes precedence in cofferdam operations. Numerous  hazards accompany the installation and upkeep of an efficient cofferdam,  including ice flows, currents, vessel traffic, rock fissures, flood  occurrences, soil conditions, and beyond. Working within confined spaces  necessitates atmospheric monitoring and emergency response protocols  for crew members. At Canadian Marine Contractors, we possess expertise  in managing a spectrum of cofferdams, ranging from large-scale cellular  structures to smaller box-type variants. We tailor comprehensive safety  plans for each unique project to mitigate risks effectively.

Constructing and installing a cofferdam constitutes just one aspect of  the task. Equally imperative is upholding an efficient de-watering  strategy, essential for ensuring the safety and productivity of the  crews involved. The presence of effective seals and contingency  de-watering plans can significantly influence the outcome of a project,  determining its success or failure.
