Main advantages of the diver mounted display system for the safety of divers

Divers are faced with operations and works under very variable conditions. Strong currents, water at very low temperatures, confined spaces, and situations in which visibility is reduced or zero, either due to the turbidity of the environment or because the action takes place at night.

Total Visibility 

Tritech, an English underwater technology company, has developed the Diver Mounted Display (DMD) system based on the use of multibeam sonars installed on a diving helmet or mask. It represents a step forward in the incorporation of this technology that was normally aimed at the ROV environment into diving operations.

These devices allow for reading the working environment or carrying out inspections when the video circuit does not offer enough guarantees. The Gemini range of multibeam sonars makes it easy for the team to select the most suitable device for each operation. The most compact model on the market, the Gemini720im, provides a basic sailing capability that is sufficient to locate large objects or structures while working in zero visibility water.

If the operation requires a higher degree of resolution, the team can opt for mounting the J20iko 1200ik models, which provide greater scope and field of vision. These devices allow for carrying out searches much more efficiently than traditional techniques.

Vision for the whole team

This system incorporates an important novelty regarding operation safety. Until now, the diver was the only member of the team who had access to the images by means of a flip-up visor built into the helmet or mask. The Diver Mounted Display can send the device readout to the video and audio circuit so that the supervisor has exactly the same view as the submerged diver.

Safety and planning

These are the main advantages of using this system when vision is limited. There are very common diving operations that take place in environments with naturally reduced visibility, such as ponds, ports, river mouths and estuaries. In these situations, a traditional camera is not very useful. However, the ultrasound sonar provides the necessary information to understand seabed conditions and the environment in which underwater work is carried out.

Regarding the diver safety in this kind of operations, it represents a very important step forward. When visibility is poor due to water conditions, divers have more limited movement, and it is more difficult to anticipate the risk of an obstacle, and underwater operations turn more complicated. By sending information from the acoustic equipment to the surface the diver and the supervisor can avoid hazardous situations underwater and to gain safety and efficiency. Locating the diver within the operations space is a warranty.n este sentido.
