Surface supplied air and radio communications are used, but if needed SCUBA gear is available. Underwater burning equipment is ALWAYS carried in my step-van. A unique hot-water wetsuit system is used in the winter for unlimited cold-water diving. This company was established in 1979 in which time over 11,000 Wheel Jobs have been made. I personally have been diving since l985 and was previously a Class I Diver/Welder with Oceaneering for over 8 years specializing in underwater burning and welding. This company is licensed and insured with $2,000,000 general aggregate liability. Wheel Job Diving has NEVER had an insurance claim or a lost time accident!
