Paying offshore crews on rotation: why it starts with the timesheet
The relief helicopter is weathered out. Your crane operator, due off on day 14, stays on for three more days. Nobody thinks twice about it offshore. Then payroll runs on the 25th, pays him the same as last month, and the problem lands in someone’s inbox a few weeks later.
Offshore pay goes wrong in small, boring ways like this all the time. Rotations don’t line up with calendar months. Hitches overrun. Travel days are paid on some contracts and not others. And in several countries, the rules on how much someone can work offshore are measured over a completely different period to onshore work.
The fix isn’t clever. It’s paying people from what actually happened, recorded and approved, rather than from what was supposed to happen.
Quick answer: to pay offshore crews on rotation correctly, run payroll from approved timesheets, not from the planned rota. Record days on board and onshore, hours and overtime, travel, standby and overstays, plus the installation and who approved it. That record also proves working-time compliance, which offshore is often measured over a full year.
Why don’t rotational crews fit normal payroll?
Monthly payroll assumes roughly the same hours every month. Offshore rotations don’t work like that. Someone on 12-hour shifts doing 14 days on and 14 off might work two full hitches in one month and barely one in the next. Some Brazilian collective agreements run 14 on and 21 off. Long-haul international rotations run longer still.
Add overstays, standby days, mobilisation travel and the odd medevac, and the gap between “what the contract says” and “what this person is owed this month” gets wide quickly.
How is offshore working time measured?
Differently depending on where the installation is. Three examples from very different regimes:
| Country | How offshore working time is limited | Source |
|---|---|---|
| UK | 48-hour average week, but averaged over 52 weeks for the offshore oil and gas sector instead of the usual 17 | GOV.UK |
| Denmark | 48 hours a week including overtime, averaged over 12 months; the offshore installation manager and the employer are both responsible for compliance | Danish Working Environment Authority |
| Brazil | No more than 15 consecutive days on the special offshore regimes, with 24 hours’ rest for each 12-hour shift worked | Law 5,811/1972 |
The 52-week reference period in the UK is what makes intensive rotations workable. Two weeks of 84-hour weeks, two weeks off, and it averages out. But it cuts both ways. To show you’ve stayed under the limit, you need a full year of reliable hours for every person. A rota on a whiteboard doesn’t count.
Do field breaks count as annual leave?
In the UK, yes. In Russell v Transocean International Resources in 2011, the Supreme Court held that employers can require offshore workers to take their statutory annual leave during onshore field breaks, because those breaks are already time away from work.
Don’t assume that travels. Other countries treat leave, rest days and field breaks differently, and some collective agreements go further than the law. It’s a country-by-country question, and the answer changes what you owe.
What should an offshore timesheet record?
At minimum:
- the dates someone was on board and the dates they were onshore
- hours worked per shift, with overtime separated out
- travel and mobilisation days, if the contract pays them
- standby or on-call periods
- any days beyond the scheduled rotation
- the installation or vessel, because tax, social security and crew quotas can depend on it
- who approved it, and when
The installation matters more than people think. In Brazil, for example, moving a foreign worker to another vessel has to be reported to the Ministry of Justice. If your timesheet doesn’t say where someone worked, you can’t prove it later.
Who should sign off offshore timesheets?
Someone who saw the work. Usually that’s the crew supervisor or the offshore installation manager. Get the approval in before payroll cut-off and most pay disputes never happen.
Day rate or salary?
Both are common offshore, and neither gets you out of tracking hours.
Day rates are easy to understand and easy to tie to a timesheet: days worked times rate. Salaried rotation contracts give crew a steadier income, which many prefer, but you still need the hours for working-time compliance and for any overtime or overstay premiums. Either way, local law sets the floor. In Brazil, for instance, extra days on board beyond the rotation are generally paid at double rate.

How do you run offshore payroll across borders?
One crew can easily hold five nationalities working in a sixth country’s waters. Each person may trigger different tax and social security rules depending on where they live, where the installation is, and who employs them.
The UK Continental Shelf is a good example of how specific this gets. HMRC has dedicated PAYE and National Insurance rules for oil and gas workers employed through offshore intermediaries.
The cleanest setup is one compliant employer in each country you work in, and one record of hours feeding all of them. That’s the job an Employer of Record does.
How AgileHRO runs offshore payroll
AgileHRO employs offshore crew as an Employer of Record in 150+ countries and runs global payroll from timesheets. Crew hours are submitted, approved by your team, and paid as worked: rotations, overtime, overstays and allowances included. You get one view of who worked where and what they were paid.
Our energy workforce team works with rotational rosters, offshore allowances and multi-country payroll every day.

Frequently asked questions
What is the working-time reference period for offshore workers in the UK?
52 weeks, compared with the standard 17.
Can offshore field breaks be used as annual leave?
In the UK, yes, following Russell v Transocean (2011). Other countries take different approaches.
Can an Employer of Record pay offshore day rates?
Yes. The EOR employs the worker and pays the agreed rate for days recorded on approved timesheets, within local law.
Who is responsible for offshore working-time compliance?
The employer. In Denmark, the offshore installation manager shares that responsibility.
Does AgileHRO handle offshore timesheets?
Yes. Timesheets are submitted, approved and fed straight into payroll.
