Student Requirements

You need to be in good health and have a high school diploma or G.E.D. to consider a career in commercial diving. All students must complete a diving physical sanctioned by the Association of Diving Contractors International (ADCI) before any diving or hyperbaric chamber exposure. Some conditions may not be safe for diving, such as diabetes, pulmonary disease, or other heart conditions. The underwater environment is most often cold and dark with limited visibility. Water currents can add to the challenging environment. The physical demands placed on your body will undoubtedly be extreme at times.

CDI provides all the technical gear you’ll need to train, but commercial divers also need a complement of personal gear as well. Students will need to provide or purchase the following items for the duration of the seven-month course:

Personal Protective Equipment

  • Hard hat
  • Safety earplugs
  • Safety glasses
  • Work gloves

Diving Equipment:

  • Gear bag
  • Dive hood
  • Dive boots
  • Scuba mask
  • Gloves with Kevlar palms
  • Fins
  • Snorkel
  • Wetsuit

Welding gear:

  • Welding helmet
  • Grinding shield
  • Slag hammer
  • Steel wire brush
  • Welding gloves
  • Welding sleeves

The cost of your gear and tools comes to approximately $900 + tax.

Take a look at the topics listed below under Commercial Diver Curriculum to get an idea of the topics you will need to master. But don’t worry, your Commercial Divers International instructors are always ready to help. Commercial diving operations require everyone to be thinking, sharp and on top of their game. Your mental acuity is, without a doubt, the single most important tool you have in your toolbox, and you will put it to use in areas that will test and challenge you.

Our program at Commercial Divers International will teach you everything you need to know to confidently and safely enter the world of commercial diving. Commercial Divers International goes the extra mile and exceeds the minimum standards of the Amerian National Standard Institute (ANSI). ANSI has established the ANSI/ACDE Minimum Standard for Commercial Diving Training. Meeting and exceeding this standard means Commercial Divers International gives you the nationally recognized commercial diving certification. Students who complete a program accredited by the Association of Commercial Diver Educators (ACDE) are eligible for an ACDE/ANSI-2015 Commercial Diver Certification and ADCI certification, which is required for employment as a commercial diver with U.S. commercial diving companies.

Commercial Diver Curriculum

Commercial Divers International’s commercial diver training program covers a wide range of subject matter. The curriculum is challenging but fascinating for students new to diving and the underwater work environment. Topics are diverse, and each one will often use and highlight the importance of the others. Commercial Divers International students will learn practical and classroom concepts for anatomy and physiology, diving physics, diving diseases, decompression tables, decompression procedures, treatment of diving-related injury or diseases including first aid and C.P.R. We will also cover seamanship and rigging, lightweight dive gear procedures, equipment maintenance, mixed gas diving, underwater welding and cutting, operations planning; keeping dive logs and records, offshore and industrial safety and procedures, blueprint reading, report writing, underwater tools, marine engines and compressors and professional standards for commercial diving.

World-Class Facilities and Equipment

Commercial Divers International’s facilities are unmatched. At our brand new 2.8-acre facility, we have three tanks of 21,000 gallons, each providing a controlled environment in which to train and practice projects. Additionally, we have a penetration tank to simulate penetration and confined space diving. The tanks have side-viewing windows so students can be observed at all times by instructors both in and outside the tank. We also have a 37 acre 60′ deep lake, Lake CDI which allows students to take their training and projects to a realistic working environment. Our hyperbaric chamber will provide the chance for students to experience and learn first hand, crucial, potentially lifesaving, chamber operations.

We offer a surface-supplied helmet diving experience to anyone considering our program, or to anyone who meets the physical requirements who want to experience the thrill of an underwater, full helmet, surface-supplied dive. Our equipment is state-of-the-art and meticulously maintained. Our students dive with the best helmets (Kirby-Morgan, Desco, Gorski) in the industry. You’ll necessarily become an expert on helmet operation and maintenance well before your program concludes. You will be trained on and develop proficiency with the same equipment you will encounter on the job.

There is, of course, a whole lot more to the job than getting wet. You’re going to be using any number of hand and power tools down there. CDI will teach you the skills you need to safely operate drills, jackhammers, saws, impact wrenches, torches, and welding equipment in the underwater, industrial work environment. In fact, almost any tool you can think of used topside has an underwater analog!

A top quality, commercial dive training school like Commercial Divers International is essential to gaining access to the commercial diving industry. Your earning potential as a commercial diver improves with every certification you obtain as well as with your expertise.
