Monday 8th February
Another new month and another new level of training. This time its Surface Supply to 30m. Today is a theory day concentrating on Surface Supplied Equipment. Band masks, helmets, air panels, umbilicals and compressors are all covered. Basic maintenance on Kirby Morgan Band Masks is completed including changing check valves, regulators, exhaust valves and regulator diaphragms. Compressors have the air analyzed and umbilicals are tested. Now we are ready for the first day of diving on surface supplied equipment.

Our first day of diving in SSBA. First things first, we have to complete the standby diver training in the new equipment. A two hour dive for everyone. After completing the rescue drills and first assessment, the divers continue on with some construction tasks. The pipeline with was surveyed during part 1 needs to be reconstructed in the correct order and the survey reports are used to assist with this process. The divers are starting to see the information gathered in part 1 is valuable in completing this task successfully. A good day of diving, with everyone completing at least a 2 hour dive each.

Day two of diving Surface Supply at ‘The Pit’. The students were keen to put their newly gained knowledge into practice. This included setting up and running the panel, helmets, unmbilicals and doing the pre-dive checks. Dressed in and emergency checks completed it was time for the second rescue assessment, which involves rescuing an unconsciousness diver from various predicaments. Rescues over and we start the first construction task – disassembling and relaying a pipeline in its correct position. The pipeline had been surveyed in level 1 so now its time to see if the student survey was accurate. Back to the classroom for logbooks and logsheets.

It’s back to the classroom and we start the rigging module. Fibre rope, steel wire rope and chain are all discussed including safe working loads, selection and inspection of equipment. Slings, crane signals, shackles, eye-bolts and bulldog clips and mechanical advantage are all part of the syllabus.

Back to 'The Pit' today and groups swapped tasks from Wednesday. Today students tackle the 'well head task' which involves using an enclosed lift bag, a chain block, various slings, eye bolts and 'D' shackles to rig the well head. The flanges are then unbolted, lifted and a gasket changed. The flanges are then lowered and re bolted and then finally de- rigged. Once both groups had completed these tasks students were keen to commence their weekend.
