A commercial diving and nondestructive testing school in Houston, Texas, training since 1969 with more than 15,000 alumni working in the diving industry worldwide. The Underwater Diver Technician track covers surface-supplied commercial diving, underwater welding, saturation diving and offshore work from ship repairs to oil rigs; the separate Nondestructive Testing track trains inspectors to use industry tools to verify safety and quality in energy, aviation and manufacturing. Both routes are hands-on certification programmes rather than academic degrees.
