ASI Group


ASI understands the need to have clean intakes and ensure all cooling water piping and tunnels, as well as other underwater assets are in good working order. 

We offer a range of underwater services that cater to the unique challenges of nuclear facilities. Not only is ASI qualified and experienced to work in irradiated environments underwater, but we are committed to the radiation safety principal ALARA (As Low As Reasonably Achievable) and operate under strict Quality Control/Assurance guidelines. 

Our highly experienced team of commercial divers, ROV pilots, hydrographers, engineers and technicians can complete underwater inspections, maintenance and repair projects safely and efficiently. Our Remotely Operated Vehicles can inspect long tunnels in a short amount of time due to our long-distance capabilities.
