Primary Advantages

o High degree of safety due to reliable remotely operated tooling (ROT)

o Effective methods for cutting steel, concrete and other composite structures o Shallow water subsea ROT tooling removes requirement of diver torch method of cutting (Brokko) o Jetcut have extensive experience in remotely operated tooling, specialised asset modification / demolition

and diamond cutting technologies

o Jetcut have a dedicated engineering and project management team capable of the necessary engineering and operations competencies required for such a demolition project

o Some other specialised tooling developed by Jetcut include subsea: concrete demolition tools, marine growth removal tools and surface preparation tools: see http://www.field.jetcut.com.au/view/videos/sub-sea-pipe-cleaning-tool http://www.field.jetcut.com.au/view/videos/aspect
