Safety & Inspections

Planning, construction, maintenance, installations and removal are the bread and butter of our business. These specialty services make Dominion Divers your first call for any marine contract work.
Safety and continued functionality come from KNOWING what is down there. Our divers have an experienced eye for good concrete and bad, structure and rubble. Our ROV gets into small spaces, and the underwater imaging done by our Blackwater Acoustic Solutions division takes much of the guesswork out of your assessment.


With winches, lift bags and ingenuity, we have recovered everything from pipes to pumps to vehicles and more — safely.

Few people have actually been underwater at these sites more often than we have. Our knowledge is your asset. Talk to us about these pillars of power and transportation, and the engineering priorities that go with them.


Cold Water Diving

In winter or the arctic — it’s just another dive site for us. The suits are heated. With a little creative planning, we can even help you with some off-season maintenance.
