In a deep sea environment, the consequences of poor communication can be life-threatening. Technical divers working in the offshore oil and gas industry need to communicate clearly with the diving bell, vessel and each other as they carry out maintenance and inspections up to several hundred meters water depth.
One of the problems faced by commercial divers is that their speech becomes less intelligible the deeper they go. This is due to the increased helium content of their gas mixture; to compensate for the effects of high pressure. The increased helium content which is lighter than air, changes the voice sound produced within the mouth, giving the diver a high pitched, difficult to interpret voice.
Another problem with traditional analogue diver communication systems is noise interference from other electrical systems. This can cause lower than desired communication clarity, particularly as systems age and cables and connectors deteriorate.
Keen to address these challenges and set new standards in diver communications, Aberdeen-based through water communication and positioning technology company Nautronix, has developed NASDive. NASDive represents the latest generation, fully digital, diver communications system which will be launched on stand number 60 at Subsea Expo at the Aberdeen Exhibition and Conference Centre on the 5th – 7th February 2014, where the system will be available for demonstrations.
Mark Patterson, CEO explains "In the past 30 years Nautronix has been a market leader in the diver communications industry through its Helle brand. We have recently focussed on the development of NASDive to refresh our diver communications product line and bring the benefits of current technology to divers. The new fully digital system sets new standards in both Hard Wired and Through Water Communication performance in mixed gas diving environments. We have invested £1 million on the development of NASDive, which shows our commitment to the product and have already secured our first customer order with future orders in the pipeline".
