Course Starts
New classes begin every five (5) weeks.
An advanced diving course takes a working commercial diver beyond surface-supplied air operations and into the deeper, more technical side of the trade. At The Ocean Corporation, the advanced course covers mixed-gas operations, bell and saturation diving systems, and underwater welding and cutting. These are the skill sets that move a diver from entry-level work into the offshore, deep-water, and industrial projects at the upper end of the commercial diving pay scale.
An advanced course in commercial diving is built on top of foundational scuba skills and surface-supplied diving fundamentals: dive physics, decompression theory, rigging, equipment maintenance, and underwater work practices. From that base, an advanced diver learns to operate at greater depths, manage longer bottom times, and complete specialized tasks that conventional air diving cannot support.
New classes begin every five (5) weeks.
Classes meet Monday through Friday for five hours a day: 7:30 am to 12:30 pm, 1:00 pm to 6:00 pm, or 6:00 pm to 11:00 pm.
Advanced diving training is included as part of The Ocean Corporation’s 30-week Commercial Diver Certification program. Coursework moves a student from classroom theory to pool session work in our dive tanks, then out to open water dive operations as the program progresses. The program is built as a full education course, not a short-format workshop, so a student leaves with the depth of training employers expect.
The commercial diving industry runs on depth and complexity. The work that pays the most and carries the most responsibility happens beyond the limits of standard surface-supplied air. Mixed-gas operations open up deeper job sites. Saturation diving lets crews live at depth and complete projects that would be impossible with bounce dives. Underwater welding and cutting puts a diver on the short list for offshore platform repair, pipeline work, ship husbandry, and salvage operations.
For divers who want to work on offshore oil and gas platforms, deepwater pipelines, subsea infrastructure, or major salvage projects, an advanced certification is the gateway. It also opens up new experiences a working diver could not access at the entry level: bell runs, saturation rotations, deep welding contracts, and international offshore work.
The Bureau of Labor Statistics reports commercial diving among the higher-paid skilled trades, with the deepest and most specialized offshore work at the upper end of that range. Advanced diving training is what positions a graduate to compete for those roles.

What is an advanced diving course?
An advanced diving course in commercial diving covers the skills and certifications a working diver needs to operate beyond standard surface-supplied air diving. At The Ocean Corporation, the advanced course covers mixed-gas operations, bell and saturation diving, and underwater welding and cutting. These are the credentials that move a diver into offshore, deepwater, and industrial work.
Is advanced diving the same as PADI Advanced Open Water?
No. PADI Advanced Open Water is a recreational scuba certification for an open water diver who wants to expand their recreational range. Advanced commercial diving training covers a different scope of work: mixed-gas systems, saturation diving, underwater welding, and the technical operations that support paid work on subsea infrastructure. The Ocean Corporation trains commercial divers, not recreational scuba divers.
Do I need to be a certified diver before enrolling?
No prior diving experience is required. The Ocean Corporation’s 30-week Commercial Diver Certification program builds a graduate from no diving background to a working commercial diver, with advanced certification training included as part of the program.
What advanced diving certifications will I earn?
Graduates earn the ADCI-aligned commercial diver certification employers expect at graduation, AWS D3.6M underwater welding certification, and training in mixed-gas and saturation diving operations. The IMCA diver certification card comes later, once a diver has logged qualifying dives with an IMCA contractor. The Ocean Corporation is the only authorized assessor and issuer of that card in the United States.
What jobs can an advanced diver work?
Advanced divers work on offshore oil and gas platforms, subsea pipeline projects, ship husbandry and salvage operations, inland industrial diving projects, and saturation diving contracts worldwide. Many graduates progress into supervisor, life support technician, and operations management roles.
How long does the program take?
The full Commercial Diver Certification program, which includes advanced diving training, takes 30 weeks. New classes start every five weeks.
How does The Ocean Corporation support job placement?
Lifetime career placement support is included for every graduate. Our career services team connects graduates with employers across the commercial diving industry, supports interview preparation and resume work, and stays available throughout the full length of a graduate’s career.
