Technical Wreck Course

technical wreck course philippines

The Technical Wreck course aims to develop the skills, knowledge and procedures required for technical level divers to operate safely in the overhead wreck environment. The course focuses on penetration and guidelines skills, along with a team approach for safe and controlled exploration inside areas of shipwrecks that pose significant hazards.

The course explains the dangers, risks, mitigating procedures and necessary techniques involved while technical diving in the overhead wreck environment, going beyond the daylight zone, beyond 40m/130ft linear distance from the surface, through restrictions and in confined spaces.


 In a nutshell:

Course Goal:  Technical Wreck Penetration
Course Duration: 5-6 Days
Number of Dives: 5 minimum
Key Areas:  Advanced Dive Planning, Guideline Deployment and Retrieval, Team Skills, Situational Awareness, Lost Line Emergency Protocol, Lost Diver Emergency Protocol, Entanglement Protocol, Cut/Snapped Line Protocol, Visual and Tactile Communications, Air-Sharing Egress, Passage Through Restrictions, Zero Visibility Drills, Light-Failure Protocol..
Course Cost: See Price List

The Technical Wreck course places a high emphasis on the refinement of core (technical) diving skills: buoyancy, trim,
weighting and situational awareness. In addition, it focuses on the management of high tolerance task loading, stress control and the development of effective team diving skills in limited/zero visibility.
Put simply; this is one of the most challenging, highly demanding courses that you could ever take… but also, without doubt, one of the most personally satisfying and rewarding!

Note: This is an advanced level, equipment intensive training program that represents an apex in diver ability and training. The certification awarded indicates the highest level of diving expertise and experience. In order to maintain the caliber of course graduates, additional practice dives under instructor supervision, may be required before certification will be awarded.


Course Duration (TecRec/ANDI)

4 days* with classroom, practical workshops and 6 dives

Day 1 – Classroom theory, equipment workshop, surface practice of penetration protocols.
Day 2 – Skills training dives 1 – 2
Day 3 – Wreck penetration dives 3 – 4
Day 4 – Wreck penetration dives 5 –  6

*A 5 day program is recommended if you prefer a more relaxed training program or more time to refine skills.

The course is performance based, not time based.

Technical Wreck Equipment Requirements

  • Double cylinders of at least 12 l/70 cf each, with isolator manifold or sidemount independents.
  • The isolator manifold is not required for divers using sidemount configuration.
  • Primary and secondary regulators for back mounted double manifolds, one
  • with two metre/seven foot hose for air sharing and one with SPG. Note: In sidemount configuration, one regulator must have the two metre/seven foot hose, and both regulators must have an SPG.
  • 1-2 Stage/decompression cylinder with regulator and SPG, properly labeled/marked, depending on qualification
  • Tec diving BCD(s) and harness (backmount or sidemount)
  • Two multigas enriched air capable dive computers, or one multigas enriched air computer and a back up single gas computer with dive tables, or one single gas enriched air computer and a backup timer and depth gauge with dive tables.
  • Exposure suit appropriate for environment and dive duration
  • Weight system (if needed). Note: Students and staff should weight for the contingency of decompressing with near-empty primary cylinders and empty or absent stage/deco cylinders.
  • Jon line (as needed for environment)
  • Inflatable signal tube, whistle and/or other visual and audible surface signaling devices. Note that a sausage type DSMB may double for the inflatable signal tube.
  • Lift bag (bright yellow preferred) or DSMB. A suitable DSMB has sufficient buoyancy to help steady a diver during a drifting decompression, and is unlikely to spill when deployed from the underwater.
  • Knife/cutting device and back up
  • Slate / Wetnotes
  • Back up mask
  • Compass
  • Primary Penetration Light
  • Back-Up Lights
  • Primary Penetration Reel
  • 2x Safety/Jump Spool

Assessment of Technical Dive Training Readiness

technical-wreck-course-philippines

Black Mask - Lost Guideline drills inside a shipwreck

In preparation for the course and before beginning open water dive training, there will be an informal assessment of the potential student’s skills and comfort level in water, along with a general assessment dive knowledge. If the potential student appears to lack dive readiness appropriate for the training level, remedial training will be offered before training progresses.
