Gas Switching Procedures
Develop structured gas switching procedures using EAN21 through 100 percent oxygen while improving awareness, communication and procedural discipline.
Team Awareness & Failures

Planned Deco Execution
Progress toward deeper planned decompression dives while integrating gas switches, ascent management, deco stops and technical diving procedures.
MELBOURNE TECHNICAL DIVING
TRAIN IN REAL TECHNICAL DIVING CONDITIONS.
Melbourne technical diving conditions provide an ideal environment for developing decompression discipline, situational awareness, communication and technical team procedures under realistic task loading.
Cold water, changing visibility, surge and environmental variability encourage divers to build stronger buoyancy control, improved awareness and more consistent procedural execution throughout staged decompression dives.
Rather than relying on controlled conditions alone, the course is designed to help divers apply decompression procedures, gas switching and ascent management within realistic local diving environments.

Team Procedures
Improve technical communication, team positioning and coordinated ascent management throughout staged dives.
Cold Water Awareness

WHY OUR ANDP TRAINING IS DIFFERENT
MORE THAN A DECOMPRESSION CERTIFICATION.
Advanced Nitrox and Decompression Procedures is where technical diving becomes planned execution. Gas choices, decompression schedules, team awareness, failure procedures and ascent discipline all need time, repetition and feedback.
Our ANDP program is intentionally structured across five training days and a minimum of nine dives to give divers time to build reliable technical habits rather than simply complete the minimum requirements.
Five Training Days
Progressive development instead of compressed, rushed deco training.
Minimum Nine Dives
More in-water repetition for gas switches, failures, ascents and team procedures.
Real Melbourne Conditions
Build decompression discipline in cold water, changing visibility and realistic task loading.
Progression Focused
Designed as a serious foundation for Trimix, CCR, cave and expedition-style technical diving.
TECHNICAL EQUIPMENT & CONFIGURATION
BUILD RELIABLE SYSTEMS BEFORE DEEPER DECOMPRESSION PROGRESSION.
Advanced Nitrox and Decompression Procedures training requires more than simply adding extra cylinders. Equipment configuration, redundancy, streamlining and procedural consistency become increasingly important as decompression obligations and task loading increase.
Prior to the commencement of the course, divers are encouraged to discuss equipment suitability and configuration with the team to ensure systems are appropriate for decompression and technical diving progression.
Technical diving equipment is highly individual and configuration-dependent. Many divers progressively refine their setup throughout training as experience, comfort and diving goals evolve.
Equipment guidance, technical equipment support and hire options are available for divers requiring assistance preparing for Advanced Nitrox and Decompression Procedures training.
Stage & Deco Cylinders
Configure and manage stage and decompression cylinders while developing gas switching awareness.
Regulator Redundancy
Build familiarity with technical regulator configurations, backup systems and equipment checks.
Runtime & Dive Computers
Improve runtime awareness, decompression tracking and dive planning discipline.
Streamlining & Team Consistency
Refine equipment positioning, hose routing and team procedures to reduce task loading.

ANDP FAQ
QUESTIONS DIVERS COMMONLY ASK BEFORE STARTING DECOMPRESSION TRAINING.
What is ANDP?
ANDP combines TDI Advanced Nitrox and Decompression Procedures into one technical diving program. It teaches divers how to plan and conduct staged decompression dives using enriched air nitrox and oxygen mixtures.
How deep can I dive after this course?
The course trains divers to plan and execute standard staged decompression dives to a maximum depth of 45 metres, within training agency standards and appropriate conditions.
Do I need previous technical diving experience?
Divers must be certified advanced scuba divers from a recognised training agency, be at least 18 years old and have proof of at least 25 logged open water dives.
Are gas fills and boat fees included?
No. Gas fills, boat fees, accommodation and transport are excluded from the course price. Technical equipment hire is available at additional cost.
Do I need my own technical equipment?
Students need suitable technical diving equipment including appropriate primary cylinders, regulators, SMB and spool, dive computer or timing device, wet notes and a stage or deco cylinder with regulator.
Technical equipment hire is available at extra cost, and students are encouraged to contact the team before the course to confirm equipment suitability.
Why is this course five days and nine dives?
Decompression diving requires repetition. Gas switching, failure management, team ascents, runtime awareness and staged decompression procedures need time to become reliable underwater habits.
The five-day structure gives divers more time to develop consistency, control and confidence rather than simply rushing through minimum exposure.Melbourne diving conditions can involve colder water, changing visibility and increased task loading, making repetition and procedural consistency especially valuable during decompression training.
What gases are used during Advanced Nitrox training?
The course covers the use of EAN21 through to 100 percent oxygen, including benefits, risks and procedures for using enriched air nitrox and oxygen for decompression diving.
Is this course suitable before Trimix, CCR or Cave training?
Yes. ANDP is a core foundation for future technical diving progression, including Trimix, CCR, cave diving and deeper expedition-style technical training pathways.
Where is ANDP training conducted in Melbourne?
Training is conducted through Extreme Watersport on the Mornington Peninsula and Melbourne dive sites suitable for decompression and technical diving development.
Why complete ANDP training in Melbourne?
Melbourne technical diving conditions provide realistic environments for developing decompression awareness, buoyancy control, gas switching discipline and technical team communication in cold water conditions.
Changing visibility, surge and increased task loading encourage divers to build stronger procedural consistency and more reliable decompression diving habits throughout staged technical dives.
