Petroleum Safety Authority of Norway reported that three minor personal injuries were reported in connection with saturated diving in 2007. This is shown in the Petroleum Safety Authority Norway's report from the diving database DSYS.
The activity level in saturated diving* was the same in 2007 as in 2006, totalling 103,112 man hours. This is five times as much as in 2005. The activity level for saturated diving has not been higher than the last two years since the beginning of the 1990s.
Hazardous situations averted
Five incidents involving averted hazardous situations were reported last year in connection with saturated diving, three of which were serious. These were a fire in an engine room, a faulty power supply for a diving support vessel and a diver being pulled by a remote-controlled submersible from 22 metres to 35 metres depth.
The personnel injuries reported were minor wounds and a pulled back muscle.
The last fatality in this type of diving happened in 1985.
No personal injuries
The activity level for surface diving* in 2007 was 117 hours in the sea, which is a small decline compared with the reported activity level for 2006 and 2005 (145 hours). We have had no reports of personal injuries or hazardous situations averted in connection with this type of diving since 1999. This correlates with a low activity level for surface diving during the period.
The Petroleum Safety Authority Norway (PSA) has established several databases in order to record and systematize information about incidents in connection with the petroleum activities.
Manned sub-sea operations (diving) are reported to the database DSYS. The reporting is done by notifying NAV (Nye arbeids- og velferdsforvaltning) on their form with appendices, and through activity reports from the operating companies. The report from this diving database was first published on the Internet last year, and contains statistics and analyses based on data from as far back as 1985.
A decline in the activity level for saturated diving is expected in 2008. However, we assume that saturated diving on the Norwegian Continental Shelf will remain at a high level until 2010.
