For works around the loading wharf / trestle 0-20msw on the best time efficient manner we normally allow a crew of 1 supervisor and 4 divers utilizing Surface Supplied Breathing Apparatus (SSBA), which incorporates unlimited air supply to the diver along with voice communications and optional video if required. Divers take turns to dive one at a time, with a standby diver on the surface ready to assist if necessary. This allow our divers team to conduct 2 NON-DECOMPRESION dives per day. We can use different breathing mix such as Nitrox when required.

Whenever diving beyond 30msw, or decompression diving is required, we supply a decompression chamber onsite which allow us to supply a safety environment for our divers within 7 minutes of the diver leaving his final stop.

 

For any diver working in close vicinity to above the water works or vessels, the likelihood of falling objects increase significantly, that is why we supply head protection in the form of a helmet Type KM77's.

Scanning for debris in the berth pockets is normally done using the vessel sounder and weighted floats to mark important discover objects on the sea floor; in this way we can cover large areas in short time. After a general identification the use of a grid search is carried out by the divers to recover any other material in the sea floor. The recovery of debris is normally done using diving lifting bags and cranes.
