Mastering the TDI Decompression Procedures Course at Oceans 5 Gili Air

Introduction

For divers looking to extend their limits beyond recreational diving, the TDI Decompression Procedures Course offers the perfect introduction to planned decompression diving. Conducted at Oceans 5 Gili Air, this course teaches divers the essential skills and knowledge required to safely plan and execute dives that require staged decompression stops.

Located in the heart of the Gili Islands, Oceans 5 Gili Air provides the ideal environment for technical dive training, offering world-class facilities and expert instruction from Ary, the only Indonesian TDI Tech Instructor on the Gili Islands. This article will explore the TDI Decompression Procedures Course, its structure, benefits, and why Oceans 5 Gili Air is the best place to train for decompression diving.

What is the TDI Decompression Procedures Course?

The TDI Decompression Procedures Course is designed for experienced divers who want to
expand their depth limits and gain proficiency in planned decompression diving. Unlike
recreational diving, which follows no-decompression limits, decompression diving allows divers
to spend extended time at deeper depths by planning mandatory stops to off-gas nitrogen
safely.

Key objectives of the course include:

Understanding decompression theory and how gases affect the human body.
Learning how to plan safe decompression schedules using dive software and tables.
Conducting gas switches using decompression cylinders to accelerate off-gassing.
Practicing emergency procedures and handling equipment failures in decompression dives.
Developing buoyancy and trim skills for controlled ascents and decompression stops.

This course is often combined with the TDI Advanced Nitrox Course, providing divers with the ability to use enriched air nitrox blends to optimize decompression times. Completing this training is a key milestone for those aiming to progress to Extended Range, Trimix, or Advanced Wreck Diving.

Course Structure and Requirements

The TDI Decompression Procedures Course consists of classroom theory, confined water training, and open water dives. Below is a breakdown of what divers can expect:

1. Theory Sessions

During the classroom sessions, students will learn about:

Decompression theory and nitrogen absorption models..
Dive planning using decompression software and tables.
Gas management and selecting optimal decompression gas mixes.
Physiological risks, including decompression sickness (DCS) and how to mitigate
them.
Emergency procedures for lost gas, gas toxicity, and equipment failures.

2. Confined Water Training

Before open water dives, students will practice:

Buoyancy control and trim with twinsets or sidemount rigs.
Gas switching drills to accelerate decompression.
Equipment handling, including stage cylinder management.
Simulated emergency procedures.

3. Open Water Dives

Students will complete four open water dives, typically conducted at depths between 20-40meters, where they will:

Execute planned decompression stops at designated depths.
Conduct gas switches safely and efficiently.
Demonstrate excellent buoyancy and trim while managing deco cylinders.
Handle real-world dive scenarios involving navigation, gas planning, and emergency
protocols.

4. Course Prerequisites

To enroll in the TDI Decompression Procedures Course, students must:

Beat least 18 years old.
Hold a TDI Advanced Nitrox certification (or equivalent).
Have a minimum of 25 logged dives.
Be comfortable with deep diving and gas management.

The Benefits of Learning Decompression Diving

By completing the TDI Decompression Procedures Course, divers unlock several key benefits:

Ability to Dive Beyond Recreational Limits

This course allows divers to safely explore deeper dive sites that require planned
decompression stops, such as deep wrecks and caves

Advanced Dive Planning Skills

Students become proficient in using dive software, tables, and gas management techniques, improving their overall dive safety.

Better Gas Utilization

With training in oxygen-rich decompression gases, divers can optimize their ascents, reducing nitrogen loading and decompression times.

Preparation for More Advanced Technical Diving

The TDI Decompression Procedures Course serves as a prerequisite for Extended Range,Trimix, and Advanced Wreck Diving, enabling divers to progress further into technical diving.
