Course Overview

The SSBA to 50m (Part 3) certification is a progressive step from ADAS Part 2 and includes the use of surface-supplied breathing apparatus. The qualification significantly increases the diver‘s ability to operate under working situations including the use of wet bells, deck decompression chambers and other work related subjects to meet offshore diving industry requirements.

The objective of Part 3 training is to prepare Part 2 Divers to both safely and competently:

  • dive on SSBA to depths of 50m
  • use hydraulic tools at depths to 50m
  • conduct decompression dives using in water decompression and SurDO2
  • act as chamber operators
  • dive using hot water suits, and operate hot water generators
  • engage in diving operations using wet bells as a in-water standby diver and surface standby diver.

Course Standards

This course meets the standards of:

  • AS 2815.3 – Air Diving to 50 metres.
  • Certificate IV in Hyperbaric Operations (Surface-supplied diving to 50m). National Qualification Code 10133NAT.
