Report on diving in 2017

There were no incidents, personal injuries or hazard situations reported in 2017, during saturation diving for petroleum activities. There have been relatively few personal injuries associated with saturation diving as part of these activities in the last 25 years.


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 1985-2017.

Activity level
In 2017, the activity level for saturation diving was 15,568 man-hours in saturation, a fall of around 65 per cent from the preceding year and the lowest average activity level since 2002. 

For surface-oriented diving, 406 man-hours in the water were reported in 2017, and no registrable undesirable incidents. 

Definitions
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.
