What is AUD?
Alcohol use disorder (AUD) is a medical condition characterised by an inability to control alcohol consumption despite negative consequences to health, relationships, or work. It exists on a spectrum from mild to severe, and is recognised by the NHS as a condition requiring clinical support rather than willpower alone. In the UK, around 600,000 people are estimated to be dependent on alcohol.
How shift work drives AUD
Shift workers face a confluence of risk factors for problematic drinking: disrupted sleep architecture elevates cortisol and reduces impulse control, making alcohol's sedative effect more appealing as a short-term sleep aid after night shifts. Social isolation from working anti-social hours reduces protective social buffers, while the psychological stress of rotating schedules may drive alcohol use as self-medication. Research also suggests circadian disruption alters the metabolism of alcohol itself, meaning shift workers may experience different intoxication thresholds at different points in their cycle.
Why Offshore Oil & Gas workers face particular risk
Home-week binge patterns — well-documented in UK offshore and maritime populations — pose metabolic and relational risks distinct from daily problem drinking.
Break structure: Standard offshore day pattern includes structured meal breaks in the platform mess (usually open round-the-clock for shift overlap), subsidised hot food, and formal handovers with built-in rest. Compared to most UK shift work, break infrastructure is strong — platform life is the one shift environment where canteen culture remains universal.
Workplace factors that compound risk
- Helicopter transfer days are fatigue-dense travel days absorbing 4–6 hours plus security, baggage, and weather delays — they shouldn't be counted as work or leisure
- Platform shift patterns (typically 12 hours on, 12 off for 14–21 consecutive days) plus the travel day plus the home recompression period compresses a working month into two weeks
- Zero alcohol on platform (mandatory) plus a two-week home week creates the binge-weighted drinking pattern OEUK welfare research has documented for years
- Two-timezone life — offshore time and home time — creates a genuine identity-split that standard shift research doesn't capture; workers who thrive treat the switch as a ritual
- Helicopter safety is a live concern given the post-2013 track record — workers carry the psychological overhead of regular transfer flights
- Remote-site caring responsibilities cannot be managed from a platform — partners or co-parents absorb the full load for two weeks at a time, and the re-entry dynamic is documented
- Pension and contract structures vary enormously between operator-direct employment and contractor roles — contractor pay can be higher, contractor job security and pensions materially worse
Evidence-based steps to reduce risk
These mitigations are supported by research evidence and are relevant to offshore oil & gas workers managing AUD:
- 1Establish a wind-down routine after night shifts that does not involve alcohol — options include a warm shower, a non-caffeinated hot drink, or light stretching
- 2Use earplugs and a sleep mask to reduce the sleep-quality deficits that make alcohol appealing as a sedative
- 3Track weekly unit consumption using a log or app; the NHS low-risk guideline is no more than 14 units spread over three or more days
- 4Connect with the NHS Drink Free Days app or speak to a GP about brief alcohol interventions available on the NHS
- 5Identify the specific shift types (e.g. the last night of a run) where drinking risk is highest and plan alternative coping strategies in advance
- 6Tell one trusted colleague, friend, or family member about your goal to reduce drinking — social accountability significantly improves outcomes
Practical tips for Offshore Oil & Gas workers
- Use the helicopter day as a travel day, not as part of either the work or home week — land, eat, sleep, avoid commitments
- Protect the first 24 hours at home as decompression — partners and family re-entry research is consistent that the first day is not social time
- Use the platform gym most days — every modern UK installation has one, and working out is one of the most protective habits offshore workers report across 30-year careers
- Manage home-week alcohol deliberately — a soft cap on units, two alcohol-free days at the start of every home week, and a firm rule that it's calibration not release
- Engage with OEUK mental-health resources and operator-specific EAPs — the infrastructure is good by industry standards and uptake is strongly protective
- On financial planning, treat the offshore premium as time-limited — pay down mortgage, fund pension, accumulate deposit, and plan an onshore exit timeline rather than drifting into permanent offshore income dependency
- Know your contract — directly employed vs contractor via agency materially affects sick pay, redundancy rights, pensions; many workers don't realise the gap until something goes wrong
When to see your GP
Self-management has limits. Seek medical advice promptly if you experience any of the following:
- Experiencing physical withdrawal symptoms such as sweating, tremor, or hallucinations when not drinking — this is a medical emergency requiring urgent review
- Unable to stop drinking for 48 hours despite wanting to, or despite a scheduled shift
- Drinking more than 50 units per week consistently
- Jaundice (yellowing of skin or whites of eyes), severe abdominal pain, or dark urine — potential signs of liver damage
- Thoughts of self-harm or suicide associated with drinking or attempts to stop
Symptoms to watch for
- Using alcohol to fall asleep after night shifts as a regular strategy
- Feeling unable to relax or unwind without drinking
- Increased tolerance — needing more alcohol to achieve the same effect
- Irritability, anxiety, or shaking when not drinking
- Concealing drinking from colleagues, partners, or managers
- Drinking before or during a shift, or immediately upon waking
Your rights: regulatory context
- Post-Piper Alpha safety framework giving workers formal safety representation and consultation rights on offshore installations — enforceable under HSE and a cornerstone of the UK offshore safety culture.
- Operators must produce and maintain a Safety Case demonstrating they can manage major-accident hazards. Fatigue management is explicitly within scope — the HSE has fined operators for roster patterns contributing to incidents.
Tools to help manage AUD
What the research shows
Research published in occupational health literature consistently suggests shift workers — particularly those on rotating or permanent night schedules — report higher rates of hazardous alcohol use than day workers, with evidence indicating that sleep disruption and circadian misalignment may both motivate alcohol use and reduce the ability to moderate it.

Common questions about Offshore Oil & Gas shift work
What's a typical offshore rotation schedule?
The two most common UK patterns: 2-on-2-off (14 consecutive 12-hour days on platform, 14 days home) and 3-on-3-off (21/21). Some roles use 1-on-1-off (7/7). Specific days on and off include travel days at each end, which in practice compress the effective 'home' period. The rota is one of the longest consecutive-working patterns in the UK — the 12-hour offshore day combined with 14–21 consecutive days produces an intensity profile distinct from any onshore shift work.
How does the helicopter transfer affect shift planning?
Treat the transfer day as a travel day, not part of either the work week or the home week. A four-hour helicopter-and-bus transfer plus security, baggage, and weather delays absorbs most of a day. Workers who pair it with errands or social commitments arrive at whichever side they're heading to already depleted. Workers who write the transfer day off — land, eat, sleep, move on — arrive properly. The sector's experienced workers are uniform on this.
How do I handle the alcohol transition between offshore and home?
Directly and deliberately. Zero alcohol offshore is mandatory and straightforward. The home-week pattern is where sector research has flagged binge-weighted consumption for years. Workers who sustain long careers cap alcohol deliberately across the home week — alcohol-free days at the start of the week, a soft cap on units across the fortnight — rather than using the home week as release from platform abstinence. OEUK and NHS guidance on this is worth reading.
