TDI Decompression Procedures in Thailand

Today Big Blue Tech completed a TDI Decompression Procedures course for Andy Holdaway, Panos Iosifoglou, and Steve Jeffs under the instruction of James Thornton-Allan. Additionally the course was joined by Nathaniel Weiss who is perfecting his skills under supervision of Technical Divemaster Christos Kardana

The TDI Decompression Procedures course, which was combined with TDI Advanced Nitrox, covers a variety of unqiue skills and training to allow the diver to complete decompression dives up to 45m using a variety of oxygen based gas mixes.

The course began with advanced buoyancy skills, equipment orientation, gas planning, task loading and handling advanced mixes of nitrox.

Today the students completed 2 accelerated decompression dives at Chumphon Pinnacle dive site in Koh Tao Thailand. The goal of all dives was to not touch the ground at any point or make contact with any object using their newly honed buoyancy skills. It was also essential to deploy a lift bag on every dive, the lift bag and reel can often lead to problems with loosing depth control or entanglement.

The students final dive exposed them to a 24 minute stop at 4.5m. Although they had already cleared their schedule according to their Suunto Vytec DS gas switching computer (provided as standard on all courses) it was essential for the students to build up tolerance to hanging in water in a controlled manner.

Tomorrow begins the start of the TDI Extended Range course which will begin with advanced oxygen handling, simulated in-water recompression procedures (full face mask), decompression buddy breathing and a variety of unique skills found only in the TDI syllabus. The TDI Extended Range course will then hit the road for Khao Sok where the students will complete their TDI Cavern Course and finish the deep dives on the sunken village in the middle of the national park. This option for training is only open to the most comfortable technical student due to it’s remote and challenging environment.
