In 1996, Sergio Smith, a former US Navy diver and member of its Seabee program, established a fitness equipment shop called East Coast Dive Connection, located in Summerville, South Carolina. It later expanded into a dive shop with scuba gear and offered recreational scuba classes as well as underwater welding certifications. The company was then turned into a school in 2003, establishing its campus in North Charleston, with underwater archaeologist E. Lee Spence as a co-owner, and retaining the Summerville location as a dive shop. In 2004, it was renamed to International Diving Institute. Both Smith and Spence have served as instructors. In 2016, 12 members of the Seabee Underwater Construction Team 2 enrolled in IDI's wet welding course. Of the 12, only two people had previous experience in surface welding. In 2017, members of UCT 2's Construction Diving Detachment Alpha participated in the two-week underwater welding certification course.
Admission requirements are: 18 years or older, GED or high school diploma, US citizen, and passing a diving physical exam. Students are not required to have previous experience. Palmetto Business Daily reported that tuition to be $18,100 for the 2017-18 year with 21 students enrolled.
Curriculum
IDI offers programs in Air/Mixed Gas Surface Supplied Welding, Underwater Welding, HAZWOPER/HAZMAT for general and commercial diving, ROV pilot, Underwater Burning, and Diving Supervisor. Courses typically run for 640 hours over 16 weeks, and meet certifications for OSHA and commercial diving jobs. Of these hours, about half is classroom lecture and the other half is practical applications as required by Association of Dive Contractors International. Some additional training courses for certifications run another two weeks. Training is done on-site in the wet tanks, at the dive stations in the Cooper River, and also nearby piers.
Campus
IDI is situated at an old Navy base on the Cooper River in North Charleston, South Carolina. Its facilities include a two-story building with classrooms, offices, and work areas. Workshops include: metal fabrication, welding, a clean room for gas systems fabrication, and diesel compressor training area. There are hyperbaric chambers for compression/decompression. The school has three wet tanks. The main tank is 48,800 gallons and is 20 feet deep, and in 2009, a tube was appended to enable students to practice working in confined spaces. A second tank is used for installing in confined spaces with minimal visibility and also for rigging and hoisting. A third tank is used for wet welding. The school also has access to the Cooper River in which dive stations have been installed. The school has a dive shop that also services other divers besides the students.
