Upgrade ADAS Part 1 to Part 3

This course gives you qualifications and knowledge in using surface supplied equipment for both inshore and offshore diving.


8 week Upgrade ADAS Part 1 to Part 3: Price tbc

This eight week course builds on the foundations learned during the ADAS Part 1 course to give you qualifications and knowledge in using surface supplied equipment for both inshore and offshore diving.  As well as gaining the essential ADAS certification to dive offshore, you’ll also get practical training and experience in subsea construction techniques.

ADAS Part 2

During the ADAS Part 2 element of this package you will also be trained in important tools and skills underwater using surface supplied equipment – all of which will provide you with valuable experience for your new career.  You’ll learn how to use underwater stills and video cameras for a survey report, as well as gaining experience of using a lifting bag and impact wrench, a hydraulic drill at depth, a jack hammer, a hydraulic chain saw and an angle grinder.

You will learn underwater welding/ oxy arc cutting techniques, which are vital subsea construction skills to have once you’re working.  You will have to plan, risk assess and participate in a major construction task using a range of specified tools, giving you a strong understanding of the task at hand from start to finish.  You will also participate in night dives, diver rescues and zero visibility dives.

ADAS Part 3

The ADAS Part 3 element of this course will provide you with the right training and certification to take your diving career offshore.  This course will add to your experience and training gained in the ADAS Part 2 Course, and will provide you with experience of diving using a wet bell and hot water suit – essential when working offshore.

You will also gain additional experience of using tools underwater at specific depths, as well as conducting a surface decompression dive.

This certification is essential for those wanting to take their commercial diving careers offshore; by completing this course, you will have the required certification to work as a commercial diver around the world.

This course is included in our commercial air diving package courses (see related courses).
