If you’re looking to start a career in the offshore oil and gas industry, you’ll quickly discover that OPITO BOSIET training isn’t optional – it’s your passport to working on offshore installations. Whether you’re a complete newcomer to the sector or transitioning from another industry, understanding what BOSIET involves and why it matters will help you take your first confident steps towards an offshore role.

This guide explains everything you need to know about OPITO BOSIET training, from what happens during the course to how long your certification remains valid.

What Is OPITO BOSIET Training?

BOSIET stands for Basic Offshore Safety Induction and Emergency Training. It’s a comprehensive safety course developed by OPITO (Offshore Petroleum Industry Training Organisation), the global standards body for offshore energy training.

The course prepares you for the unique hazards of working on offshore oil and gas installations. Unlike standard workplace safety training, BOSIET focuses on scenarios specific to the offshore environment: helicopter travel, emergency evacuation procedures, survival at sea, and responding to incidents on platforms or rigs.

OPITO BOSIET training is recognised internationally across the offshore oil and gas industry. Most operators won’t allow you onto an installation without valid BOSIET certification, making it an essential requirement rather than a recommended extra.

The training combines classroom theory with highly practical exercises. You’ll spend considerable time in pool facilities and simulators, practising skills you genuinely hope never to use in reality – but absolutely need to know if an emergency occurs.

What Does BOSIET Training Cover?

OPITO BOSIET training typically runs over three to four days and covers several core modules. Here’s what you can expect:

Safety Induction and Emergency Response

The course begins with classroom sessions covering offshore safety management, hazard awareness, and your responsibilities as an offshore worker. You’ll learn about the particular risks present on installations, from hydrocarbon releases to structural hazards.

Emergency response procedures form a crucial part of this module. You’ll understand muster procedures, alarm systems, and the chain of command during incidents. This isn’t abstract theory – you’ll practise mustering and understand exactly what happens from the moment an alarm sounds.

Helicopter Safety and Escape

Most offshore workers travel to installations by helicopter, which introduces specific risks. BOSIET includes comprehensive helicopter safety training, covering pre-flight briefings, safe boarding and disembarking, proper use of safety equipment, and what to do if things go wrong.

The practical element involves escaping from a helicopter ditched in water. You’ll be strapped into a helicopter simulator (a replica fuselage), which is then submerged in a pool and capsized. You’ll practise escaping whilst the simulator is upright, inverted, and in various orientations – initially with emergency lighting, then in complete darkness.

This sounds daunting, and it can be challenging, but instructors guide you through progressively, ensuring you’re comfortable at each stage before advancing. The experience builds genuine confidence in your ability to escape should the unthinkable happen.

Sea Survival

If you need to evacuate an installation, you may end up in the water. The sea survival module teaches you how to stay alive until rescue arrives.

You’ll learn about hypothermia, the effects of cold water immersion, and survival positions that conserve body heat. Practical exercises include jumping into the pool from a height (simulating evacuation from a platform), swimming in a survival suit, deploying and boarding life rafts, and surviving in a life raft as part of a group.

The training covers both individual survival techniques and group survival, as you’re likely to be with other workers during an emergency. You’ll also learn about signalling to rescuers and what to expect during helicopter winching operations.

Firefighting and Self-Rescue

Offshore installations handle flammable hydrocarbons, making fire a serious risk. BOSIET includes basic firefighting training appropriate for your role as an offshore worker (not specialist firefighting personnel).

You’ll learn about different classes of fire, how fires develop in enclosed spaces, and the appropriate extinguishing methods. Practical exercises typically involve using fire extinguishers on controlled fires, so you understand how they work and build confidence in using them effectively.

The self-rescue element teaches you how to escape through smoke-filled environments. You’ll practise navigating through darkened, smoke-filled compartments whilst staying low and using walls and handrails for orientation.

First Aid

Basic first aid forms part of BOSIET, though it’s less extensive than dedicated first aid courses. You’ll learn essential skills relevant to offshore incidents: managing casualties, dealing with shock, controlling bleeding, and cardiopulmonary resuscitation (CPR).

The emphasis is on immediate response whilst awaiting the platform medic or evacuation to shore. You’ll understand your role as a first responder and the limitations of what you should attempt without medical training.

Who Needs OPITO BOSIET Training?

BOSIET is required for anyone working on offshore oil and gas installations in most jurisdictions worldwide. This includes:

  • Drilling personnel
  • Production technicians
  • Maintenance engineers
  • Scaffolders and riggers
  • Catering staff
  • Administrative personnel
  • Contractors visiting installations

Essentially, if your work takes you offshore, you need BOSIET certification. Employers won’t process you through their onboarding procedures without valid certification, and helicopter operators won’t carry you to installations without it.

The training is designed for people with no previous offshore experience, so it’s entirely suitable for career changers. You don’t need to be exceptionally fit, though a reasonable level of health is necessary for the physical elements, particularly the helicopter escape exercises.

How Long Does BOSIET Certification Last?

OPITO BOSIET certification is valid for four years from the date of successful completion. This is a critical point: your certificate must be renewed before it expires.

If your BOSIET certificate expires, you generally cannot simply take a refresher course – you’ll need to complete the full BOSIET programme again. This means another three to four days of training and the associated costs, so keeping track of your expiry date is important.

Before your initial BOSIET expires, you can attend BOSIET with CA-EBS (Combined BOSIET and Further Offshore Emergency Training with Compressed Air Emergency Breathing System). This is a shorter refresher course, typically lasting 1.5 to 2 days, which updates and revalidates your certification for another four years.

Many offshore workers set reminders well in advance of their expiry date to book refresher training. Given that course availability can be limited at busy times, booking three to six months ahead is sensible.

BOSIET vs FOET: Understanding the Difference

When researching offshore training, you’ll encounter FOET (Further Offshore Emergency Training) alongside BOSIET. Understanding the relationship between these courses helps you plan your training pathway.

BOSIET is the initial certification required for your first offshore role. FOET is the refresher course you take before your BOSIET expires, which revalidates your certification for another four years.

FOET assumes you’ve previously completed BOSIET and have maintained competency through offshore work. It revisits core skills – helicopter escape, sea survival, firefighting – but at a more advanced level and in less time than the initial BOSIET.

Some training providers offer combined courses (BOSIET with CA-EBS, or FOET with CA-EBS) that include additional modules. The CA-EBS component covers using compressed air emergency breathing systems, which some installations require depending on their hazard assessments.

Medical Requirements for BOSIET Training

Before undertaking OPITO BOSIET training, you’ll need to obtain an offshore medical certificate. The specific medical standard required depends on your intended work location and employer.

For UK offshore installations, most workers require an ENG1 medical certificate issued by an approved doctor. This medical assesses your fitness for offshore work and is valid for two years (or one year if you’re over 40 when first examined).

The medical examines various health factors, but particular attention is paid to cardiovascular health, respiratory function, and conditions that might be problematic in the confined environment of a helicopter or whilst wearing survival equipment.

If you have any health conditions, discuss these with your doctor before booking BOSIET training. Some conditions may not prevent offshore work but might require additional assessments or restrictions. It’s better to address these early rather than discovering issues after paying for training.

The physical demands of BOSIET – particularly the helicopter escape module – are significant. You’ll be holding your breath underwater, escaping from confined spaces, and exerting yourself in survival suits. The medical ensures you’re fit for these activities.

What to Bring and How to Prepare

Training providers supply most specialist equipment (survival suits, life jackets, breathing apparatus), but you’ll need to bring certain items:

  • Swimming costume or trunks (essential for pool exercises)
  • Towel and toiletries
  • Comfortable clothing suitable for physical activity
  • Footwear with good grip
  • Prescription glasses or contact lenses if needed (you’ll wear them during exercises)

If you wear contact lenses, consider whether you’re comfortable wearing them underwater or if glasses might be preferable for the course. Some participants bring goggles, though these aren’t essential.

Physical preparation helps. You don’t need to be an athlete, but if you haven’t swum recently, visiting a pool beforehand builds confidence. The helicopter escape exercises require you to hold your breath briefly whilst underwater – nothing extreme, but being comfortable with water helps enormously.

Mental preparation matters too. The helicopter simulator exercises can feel intense, particularly when inverted and submerged. Understanding that instructors control the experience, progress gradually, and won’t push you beyond safe limits helps manage anxiety.

Many participants find the anticipation harder than the reality. Once you’re engaged in the training, focused on the tasks, and supported by instructors, it becomes manageable and even empowering.

Choosing a Training Provider

OPITO-approved training centres deliver BOSIET worldwide. In the UK, numerous centres operate in Scotland, particularly around Aberdeen, as well as in other locations.

When selecting a provider, consider:

Approval Status: Verify the centre is OPITO-approved. Only approved centres can issue valid OPITO certificates.

Location: Training centres near major offshore hubs often offer more course dates and better transport links. However, centres elsewhere in the UK may offer competitive pricing and availability.

Facilities: Modern facilities with well-maintained simulators and pools make training more effective and comfortable.

Course Dates: Book well in advance, especially if you need certification by a specific date for employment.

Pricing: BOSIET costs vary between providers but typically range from £600 to £900 for the initial course. FOET refresher courses cost less, usually £400 to £600. Prices often include certification fees but check what’s covered. At Stream Marine Training, our BOSIET is £500 + VAT, making us one of the lowest cost and easily accessible BOSIET providers in the UK.°

Your employer may have preferred training providers or specific requirements about where you complete training. Check with them before booking if you’ve already secured employment.

After BOSIET: Your Next Steps

Completing OPITO BOSIET training is a significant milestone towards offshore employment. With your certificate, you can apply for offshore positions and, once employed, travel to installations.

Your BOSIET certificate will be stored in the OPITO database, which employers and operators can verify. You’ll receive a physical certificate and a card-sized version for your wallet. Keep both safe and maintain digital copies.

Beyond BOSIET, further training may be required depending on your specific role:

  • STCW Basic Safety Training if you’re working on mobile offshore units (vessels rather than fixed platforms)
  • Confined Space Entry training for certain technical roles
  • Working at Height certification for roles involving elevated work
  • Specific technical qualifications related to your job function

BOSIET opens the door, but the offshore industry values ongoing competence development. Many offshore workers build portfolios of certifications throughout their careers, enabling them to take on diverse roles and responsibilities.

Remember that your BOSIET doesn’t just satisfy a bureaucratic requirement – the skills you learn could save your life or the lives of your colleagues. Treat the training seriously, engage fully with the exercises, and maintain awareness of safety procedures throughout your offshore career.

Frequently Asked Questions

How difficult is OPITO BOSIET training?

OPITO BOSIET training is physically and mentally challenging but designed to be achievable for people with reasonable health and fitness. The most demanding element is typically the helicopter underwater escape training, which involves being submerged and inverted in a simulator. However, instructors build up the exercises progressively, starting with simple escapes before advancing to more complex scenarios. You’ll receive thorough briefings and support throughout. Many participants who feel anxious beforehand find they manage better than expected once they’re engaged in the training. If you can swim reasonably confidently and don’t have significant claustrophobia or panic in water, you should be able to complete the course successfully.

Can I do BOSIET if I’m not a strong swimmer?

You don’t need to be an excellent swimmer to complete BOSIET, but you must be comfortable in water and able to swim whilst wearing a survival suit. The training takes place in a pool, not open water, and you’ll wear flotation equipment during exercises. Life jackets and survival suits provide buoyancy, so you’re not relying purely on swimming ability. However, you will need to tread water, swim short distances, and manoeuvre yourself in the pool. If you’re genuinely unable to swim or extremely uncomfortable in water, BOSIET will be very difficult. If you’re just not a confident swimmer, practising in a pool before the course will help significantly. At Stream Marine Training, non-swimmers or weak swimmers can identify themselves to training staff and will be provided an appropriate coloured helmet, allowing our in-pool diving team to clearly identify and provide extra assistance should they require it. This ensures you receive the support needed to complete the exercises safely and successfully.

What happens if I can’t complete the helicopter escape exercises?

If you’re unable to complete elements of the helicopter escape training, instructors will work with you to address specific difficulties. They may allow additional attempts, provide extra coaching, or adjust the approach to help you succeed. However, successful completion of all escape scenarios is mandatory for certification – there’s no partial qualification. If you ultimately cannot complete the exercises, you won’t receive your BOSIET certificate. The cost of training is generally non-refundable if you voluntarily withdraw or cannot complete the requirements. This is why addressing any concerns about water confidence or claustrophobia before booking is important. Some people who struggle initially do return and successfully complete the training after additional preparation.

How long before expiry should I book my FOET refresher?

You should book FOET refresher training at least three to six months before your BOSIET certificate expires. This timeline accounts for limited course availability during busy periods and allows flexibility if you need to reschedule. Many offshore workers set a reminder six months before expiry to research available courses and make a booking. Your certificate must be valid on the day you complete the refresher – if it expires before you attend the course, you’ll need to complete the full BOSIET again rather than the shorter FOET. Some employers provide training coordination and will notify you when renewal is approaching, but ultimate responsibility for maintaining valid certification rests with you. Missing your renewal window can mean several days of additional training and significantly higher costs.

Does BOSIET training include an exam or assessment?

BOSIET is primarily assessed through continuous practical observation rather than written exams. Instructors monitor your performance throughout the exercises, ensuring you demonstrate competence in each skill area. You’ll need to show you can correctly don survival equipment, escape from the helicopter simulator, deploy and board a life raft, use firefighting equipment, and perform basic first aid. There may be short knowledge checks during classroom sessions to confirm understanding of safety procedures and emergency protocols, but these are typically informal rather than formal exams. Assessment is essentially pass/fail – you either demonstrate competence in all required elements and receive certification, or you don’t. Instructors provide feedback throughout to help you meet the standards.

Can I use OPITO BOSIET for offshore wind farms?

OPITO BOSIET training is specifically designed for the offshore oil and gas industry, and offshore wind installations have different safety requirements. Offshore wind projects typically require GWO (Global Wind Organisation) training instead, particularly the GWO Basic Safety Training suite and potentially GWO Sea Survival. Some elements overlap – both industries require helicopter safety and sea survival training – but the certifications are not interchangeable. If you’re pursuing a career in offshore renewables rather than oil and gas, you should investigate which GWO qualifications are required for your intended role. Some training centres offer both OPITO and GWO courses. If you might work across both industries, you may eventually need both sets of certifications, as employers will specify which standard they require.

Is BOSIET recognised internationally or only in the UK?

OPITO BOSIET training is recognised internationally throughout the offshore oil and gas industry. OPITO sets global standards, and BOSIET certification from an approved centre is accepted by operators worldwide, including in the North Sea, Middle East, Southeast Asia, Africa, and the Americas. This international recognition is one of BOSIET’s significant advantages – your UK-obtained certification opens doors to offshore opportunities globally. However, some regions or specific operators may have additional local requirements on top of BOSIET. For example, working offshore Australia may require additional tropical sea survival training, whilst some locations require region-specific safety inductions. Always verify the complete training requirements for your specific destination, but BOSIET itself forms the widely accepted foundation for offshore safety certification worldwide.

What’s the difference between BOSIET and BOSIET with CA-EBS?

Standard BOSIET covers core offshore safety and emergency response skills including helicopter escape, sea survival, firefighting, and first aid. BOSIET with CA-EBS (Compressed Air Emergency Breathing System) includes all the standard BOSIET content plus an additional module on using compressed air breathing systems during emergencies. CA-EBS provides breathable air in situations where the atmosphere is compromised, such as smoke-filled areas or following gas releases. Some offshore installations require CA-EBS training depending on their specific hazard assessments and emergency procedures. If you’re unsure which version you need, check with your employer or the operator of the installation where you’ll work. Taking BOSIET with CA-EBS initially is often sensible even if not immediately required, as it provides more comprehensive training and may be needed for future roles.
