The Health and Safety Executive (HSE) has released its offshore statistics for last year, showing it raised more than 900 non-compliance issues with operators.
914 issues were identified in 2017, a five-year high, up from 652 in 2012.
The regulatory report covers incidents from a range of oil and gas installations, pipeline and wells activities, windfarms and diving operations.
Non-compliance issues are less significant than more formal enforcement notices, which remained the same as 2016 at 38, and down from 43 in 2014.
Six prohibition notices were served.
There were 196 “dangerous occurrences” and 110 oil and gas releases, however just one of these was considered “major”.
HSE said this has fluctuated over the last 10 years, but has seen a “steady decrease” since 2013.
The regulator carried out 141 inspections at 110 platforms, however no prosecution cases were started last year.
Musculoskeletal conditions, such as hand-arm vibration syndrome had the highest number of reports between 2012 and 2017 at 32, followed by viral and bacterial conditions such as chickenpox at 31.
