Hours worked
The actual ‘hours worked’, including overtime hours, are recorded in the case of onshore operations. The hours worked by an individual will generally be about 2,000 per year. For offshore workers, the ‘hours worked’ are calculated on a 12-hour work day. Consequently average hours worked per year will vary from 1,600 to 2,300 hours per person depending upon the on/off shift ratio. Vacations and leaves are excluded.
