Technical Diver Progression

Part 2

Decompression Procedures

 

 

 

 

Decompression Procedures is the course that follows Advanced Nitrox.  When Advanced Nitrox and Decompression Procedures are taught in conjunction with each other,  the name of the course is often abbreviated to AN/DP.  The Decompression procedures course can be taught by itself, but it is much more common to take the AN/DP course as a whole instead of splitting the courses up.

During the Decompression Procedures course, you will learn how to safely go beyond the No Decompression Limits that recreational divers must obey.  You will take  what you learned in Advanced Nitrox and apply it to dives below recreational depth limits, to a maximum depth of 150′.  Additionally, you will learn how to manage failures while ensuring that all mandatory decompression stops are completed and will learn how to plan every aspect of a dive topside. Technical diving is very much a team activity, and successful dives during this course require teamwork, awareness and precision.  Below is a list of some of the skills covered during the course,  both in water and in classroom.

• Selecting bottom and decompression gasses and cylinders
• Planning dives using a dive planner, dive computer, and ratios.
• Decompression diving history and theory
• Team awareness and communication
• Proper trim, buoyancy and propulsion techniques
• Gear selection
• SMB use
• Planning for and solving complex failures
• Drift decompression vs anchor line decompression
• Oxygen Toxicity
• Emergency procedures

 

The decompression procedures course allows you to dive to a maximum depth of 150′ using breathing gasses with between 21% and 100% Oxygen.  These are Planned decompression dives, which means you will know what the decompression stop schedule looks like well before you jump in the water.  This course is designed to give divers the tools, knowledge and skills needed to safely execute dives beyond recreational limits.  This course DOES NOT allow the use of Helium integrated into breathing gasses, which can be a major issue when diving to the limits of this certification.  Read more here about the TDI Helitrox program, which allows up to 35% Helium to be used in the divers breathing gas.
