ADAS Part 3 outline
The Part 1 and Part 2 programs are to be followed by a further four weeks’ (that is, a minimum of 20 days over a 26-day period) training and assessment program. It is to be conducted according to the requirements outlined in this document.
The objective of Part 3 training is to prepare experienced Part 2 divers to safely and competently:
- dive on SSBAto depths of 50 msw
- use hydraulic tools at depths to 50 msw
- conduct decompression dives using in-water decompressionand SurDO2
- act as Chamber Operators
- dive using hot water suits, and operate hot water generators
- engage in diving operations using wet bells:
-as a diver
-as an in-water standby diver
-as a surface standby diver.
Part 3 divers are also required to have sufficient awareness of the offshore environment to facilitate their entry to the offshore petroleum industry.
Planning for deep dives is to be undertaken in a conservative manner erring on the side of safety. When diving deeper than 40 metres, the program is structured so that trainees undertake no more than one dive in a 24-hour period and are adequately refreshed and rested.
The theory component of the course is to be conducted using the ADAS theory text and must meet the requirements of the ADAS Competency Standards.
All dives are to be conducted using band masksor demand helmets and underwater communications.
Trainees are to be assessed on at least two occasions on the preparation of an effective risk assessment for dives involving relevant equipment and work tasks.
The program is to include at least:
(a) one zero visibilityor night divein the 21 to 24 metre range
(b) one work-up training diveto between 28 and 30 metres using a hydraulic tool
(c) one training and one assessment dive to at least 36 metre using a hydraulic tool
(d) one training and one assessment dive using hot water suits
(e) in-water decompressionprocedures; and at least 6 simulated in-water decompression dives using both lazy shotand dive stage
(f) training and assessment in the operation and maintenance of hot water generators
(g) surface decompression procedureson oxygen (SurDO2) and a minimum of 2 dives to at least 44 metres using hot water suitsand undertaking SurDO2 drills
(h) at least 2 dives to between 48 and 50 metres using hot water suits
(i) underwater deployments using wet bells.
