Saturation diving is one of the most demanding and highly specialized careers in the commercial diving industry. It involves working at extreme depths for extended periods, utilizing sophisticated diving systems to ensure diver safety and efficiency. If you’ve ever wondered how to become a saturation diver, this guide will walk you through the essential steps, from foundational training to certification and job acquisition.

Understanding Saturation Diving

Before diving into the process of becoming a saturation diver, it’s essential to understand what the job entails. Saturation divers work on deep-sea projects such as underwater construction, pipeline maintenance, and salvage operations. Unlike standard commercial divers, they live in a pressurized chamber for extended durations, allowing their bodies to remain saturated with inert gases. This technique eliminates the need for frequent decompression, reducing the risk of decompression sickness (the bends) while maximizing bottom time.

Step 1: Meet the Basic Requirements

Saturation diving is not for everyone. It demands a high level of physical and mental endurance. Before pursuing this career, you must meet several basic qualifications:

• Age: Most commercial diving schools require candidates to be at least 18 years old.
• Physical Fitness: Divers must pass a thorough medical examination to ensure they are free of conditions that could cause complications underwater, such as heart disease or respiratory issues.
• Swimming Proficiency: While not a competitive swimmer, you must be comfortable in the water and demonstrate strong swimming skills.
• Educational Background: A high school diploma or GED is typically required. Some advanced diving programs may prefer candidates with technical or mechanical backgrounds.

Step 2: Enroll in a Commercial Diving School

The journey to becoming a saturation diver starts with foundational commercial diving training. A reputable institution, such as Florida Commercial Diving Institute (FCDI), offers rigorous programs that teach aspiring divers the essential skills required for the industry.

What You’ll Learn in Commercial Diving School

During commercial diving training, students are introduced to fundamental concepts and hands-on experiences, including:

• Underwater welding and cutting
• Hazmat and salvage operations
• Hyperbaric chamber operation
• Use of surface-supplied air systems
• Diving physics and physiology
• Emergency and safety procedures

By the end of the program, graduates are equipped with the knowledge and skills required to secure entry-level commercial diving jobs.

Step 3: Gain Commercial Diving Experience

Saturation diving is not an entry-level position. To qualify, divers must accumulate substantial experience working in the field. Many start their careers in roles such as:

• Inshore and offshore commercial diving
• Underwater welding and construction
• Inspection and maintenance of subsea structures
• ROV (Remotely Operated Vehicle) operations

Most saturation diving companies require candidates to have at least three to five years of experience in commercial diving before considering them for advanced training.

Step 4: Obtain Advanced Diving Certifications

Beyond basic commercial diving certification, you must acquire advanced qualifications. The most important include:

1. Diver Medical Technician (DMT) Certification

Since saturation divers spend extended periods at depth, medical emergencies require immediate on-site intervention. The DMT certification ensures that divers are trained in hyperbaric medicine and emergency medical procedures.

2. Closed Bell/Saturation Diving Training

This specialized training focuses on working with diving bells and hyperbaric living chambers. It covers essential topics such as:

• Saturation systems operation
• Breathing gas management (heliox mixtures)
• Decompression procedures and gas saturation principles
• Emergency response and chamber evacuation

3. International Certifications

Depending on where you plan to work, you may need international certifications such as:

• IMCA (International Marine Contractors Association) certification
• ADCI (Association of Diving Contractors International) certification
• DCBC (Diver Certification Board of Canada) certification

These certifications ensure compliance with international safety and operational standards.

Step 5: Apply for Saturation Diving Jobs

Once you’ve accumulated the necessary experience and certifications, it’s time to start applying for saturation diving positions. Most job opportunities exist in:

• Offshore oil and gas industries (platform maintenance, pipeline inspection)
• Salvage and marine construction (shipwreck recovery, deep-sea installations)
• Military and government contracts (underwater demolition, intelligence operations)

Networking is crucial in securing opportunities. Many saturation divers are hired through industry connections, diving contractors, and professional associations.

Step 6: Maintain Physical and Mental Fitness

Saturation diving is physically and mentally demanding. To stay in peak condition, divers must:

• Undergo routine medical examinations to maintain their commercial diving certification.
• Maintain cardiovascular and muscular endurance through regular exercise.
• Develop strong mental resilience to cope with isolation, confined spaces, and high-pressure environments.
• Stay up-to-date with industry advancements by attending refresher courses and specialized training.

Step 7: Advance Your Career in Saturation Diving

Once you establish yourself as a professional saturation diver, you may choose to specialize in different areas, such as:

• Dive supervisor: Overseeing dive teams and managing operational safety.
• Saturation system operator: Controlling and monitoring the complex systems that support divers.
• Diving instructor: Training the next generation of commercial and saturation divers.
• ROV pilot: Using remotely operated vehicles for deep-sea exploration and inspection.

With years of experience, some divers transition into managerial roles, consulting positions, or even running their own diving operations.
