The results are presented in our annual report from the DSYS diving database. The report contains statistics and analyses based on data from the period 1985-2016.
In 2016, the activity level for saturation diving was 44,569 man-hours in saturation, a fall of around 23 per cent from the preceding year and somewhat lower than the average activity level in the last 20 years, which is 63,000 man-hours in saturation. Going forward, a normal level of activity in saturation diving on the Norwegian Continental Shelf is expected.
For surface-oriented diving, 219 man-hours in the water were reported in 2016, and no undesirable incidents. Although the number of hours in the water in 2016 was considerably higher than in the preceding year, the activity level for surface-oriented diving is generally low, as it has been for the last 20 years.
Saturation diving: The diver works from a diving bell that carries the diver under pressure from a chamber on the ship to the work site in the water. The diver is kept under pressure in a chamber on the diving vessel between work sessions.
Surface-oriented diving: The diver enters the water at the surface, performs the work at the relevant working depth (less than 50 metres), and returns to the surface. This kind of diving may include extra compression/decompression in a chamber at the surface.
Few personal injuries
The DSYS analysis shows that there have been relatively few personal injuries associated with saturation diving in the last 25 years.
In 2016, there were no reports of incidents involving personal injuries.
