Who needs to hold a valid BOSIET certificate?
If you work offshore or plan to start, you’ve likely come across the term BOSIET. This certification is one of the most recognised safety requirements in the offshore industry, and knowing whether you need it, what it covers, and how to get it can save you time and keep you compliant before your next project begins.
What is a BOSIET certificate and what does it cover?
A BOSIET certificate, short for Basic Offshore Safety Induction and Emergency Training, is a mandatory safety qualification required for personnel working on offshore installations. Developed and governed by OPITO, the global standard-setting body for the oil and gas industry, BOSIET equips workers with the fundamental skills needed to survive and respond to emergencies in an offshore environment.
The training covers a broad range of emergency scenarios that offshore workers may face. Key topics include:
- Helicopter underwater escape training (HUET), including controlled breathing and emergency exits
- Sea survival techniques and the use of personal protective equipment
- Firefighting and fire prevention on offshore installations
- First aid and emergency response procedures
- Self-rescue and evacuation procedures
- Safe working practices and hazard awareness specific to offshore environments
The course combines classroom-based learning with hands-on practical exercises, including pool-based helicopter escape simulations. This practical approach ensures that participants are not just certified on paper but genuinely prepared for the conditions they may encounter offshore.
Who is required to hold a valid BOSIET certificate?
Anyone who works on or travels to an offshore oil and gas installation is required to hold a valid BOSIET certificate. This applies to a wide range of professionals, regardless of their specific role on the installation. The requirement is set by OPITO and is enforced across the global offshore industry.
The following groups typically need to complete BOSIET training before going offshore:
- Offshore oil and gas workers in any technical or operational role
- Engineers, technicians, and maintenance personnel
- Contractors and freelancers visiting installations for short-term work
- Supervisors and project managers working offshore
- Catering, logistics, and support staff based on installations
- Visitors, inspectors, and auditors travelling to offshore platforms
In short, if you set foot on an offshore installation, your employer or the installation operator will almost certainly require you to hold a valid BOSIET offshore certificate. It is not role-specific; it is a baseline safety requirement for everyone on board. If you are unsure whether this applies to your role, contact FMTC Safety and we can help clarify your requirements.
What’s the difference between BOSIET and FOET?
The key difference between BOSIET and FOET is that BOSIET is the initial certification for first-time offshore workers, while FOET (Further Offshore Emergency Training) is the renewal course for those whose BOSIET certificate has expired. BOSIET is longer and more comprehensive; FOET is a shorter refresher that updates your existing knowledge and skills.
BOSIET is typically a three-day course designed for people entering the offshore industry for the first time. It covers all foundational emergency response skills from scratch. FOET, by contrast, assumes you already have that foundational knowledge and focuses on refreshing and reinforcing it, particularly the practical elements such as helicopter underwater escape.
It is important to note that you cannot take a FOET course without first having completed a BOSIET course. The two qualifications are sequential, not interchangeable. If your BOSIET or FOET certificate has lapsed and more than a certain period has passed, you may be required to retake the full BOSIET course rather than the shorter FOET course. Always check the specific requirements of your employer or installation operator before booking. You can explore both options through our OPITO HUET, FOET and BOSIET courses overview.
How long is a BOSIET certificate valid for?
A BOSIET certificate is valid for four years from the date of issue. Before it expires, certificate holders must complete a FOET course to maintain their offshore certification and remain eligible to work on offshore installations.
Keeping track of your expiry date is important, as working offshore with an expired certificate is not permitted. Many employers and installation operators will check your certification status before allowing access to the installation. Booking your FOET renewal in advance, rather than waiting until the last moment, helps you avoid gaps in your certification and any disruption to your work schedule.
It is also worth noting that some operators may have additional or slightly different requirements depending on the region or installation type, so always confirm the specific validity requirements with your employer or project coordinator.
Where can you get BOSIET certified?
BOSIET training is offered at OPITO-approved training centres around the world. When choosing a provider, it is important to ensure the centre holds valid OPITO accreditation, as only accredited centres can issue recognised BOSIET certificates.
When selecting a training location, consider the following:
- Accreditation: Confirm the training centre is OPITO-approved and that the specific course variant you need is included in their scope of approval.
- Location: Choose a centre that is conveniently located relative to your home base, port, or project departure point to minimise travel time.
- Course availability: Look for a provider with flexible scheduling and guaranteed course dates, so your training is not cancelled due to low participant numbers.
- Flexibility: Check whether the provider allows free cancellation or rescheduling close to the course date, which is particularly useful for contractors with changing project timelines.
Our training centres are strategically located near major airports, ports, and industry hubs, making it straightforward to complete your certification before heading to a project. View all available offshore training options to find the most convenient option for you.

Frequently Asked Questions
Can I take my BOSIET course online, or does it have to be done in person?
BOSIET training cannot be completed entirely online because it includes mandatory hands-on practical exercises, most notably the pool-based helicopter underwater escape training (HUET). However, some OPITO-approved providers offer a blended learning format where the theoretical and knowledge-based elements are completed online before you attend the in-person practical sessions. This can reduce the time you need to spend at the training centre, which is useful for busy offshore professionals.
What should I bring to my BOSIET course, and how should I prepare beforehand?
You will typically need to bring a valid photo ID, any relevant medical documentation, and comfortable clothing suitable for physical activity, including swimwear or suitable attire for the pool-based exercises. It is also advisable to inform the training provider in advance of any medical conditions, injuries, or swimming limitations, as some elements of the course involve water-based activities. Arriving well-rested and having reviewed any pre-course materials your provider sends will help you get the most out of the training.
Are there any medical or fitness requirements I need to meet before taking BOSIET?
Yes, because BOSIET includes physically demanding elements such as helicopter underwater escape simulations, participants are generally required to meet a basic level of fitness and hold a valid offshore medical certificate (such as an OGUK/UKOOA medical) before attending. If you have concerns about a specific health condition, contact your training provider in advance, as some exercises may have alternative arrangements for participants with certain medical needs. Do not wait until the day of the course to raise medical concerns, as this could prevent you from completing the training.
What happens if my BOSIET or FOET certificate has already expired? Do I have to start over?
If your certificate has lapsed, whether you need to retake the full BOSIET course or can complete a FOET refresher depends on how long it has been expired and the specific requirements of your employer or installation operator. In many cases, if the certificate has been expired for an extended period, operators will require you to complete the full BOSIET course again rather than the shorter FOET. Always check directly with your employer or the installation operator before booking, as requirements can vary by region and operator.
Is a BOSIET certificate recognised internationally, or do I need different certifications for different countries?
Because BOSIET is governed by OPITO, a globally recognised standard-setting body, the certification is widely accepted across international offshore operations, including in the North Sea, the Middle East, West Africa, and Southeast Asia. However, some regions or specific operators may have additional local requirements or preferred course variants on top of the standard BOSIET. Before travelling to a new region or starting a new project, confirm with your employer or the installation operator that your specific BOSIET variant meets their local compliance requirements.
What are the most common mistakes people make when booking their BOSIET training?
One of the most frequent mistakes is booking too close to a project start date, leaving no buffer if the course is rescheduled or if you need to retake a practical element. Another common error is not verifying that the training centre is OPITO-accredited for the specific course variant required, as not all centres offer every variant. Finally, some workers forget to check whether their offshore medical certificate is still valid before attending, which can prevent them from completing the course entirely.
Can my employer arrange group BOSIET training for a whole team, and is that more cost-effective?
Yes, most OPITO-accredited training providers, including FMTC Safety, can accommodate group bookings for teams or organisations sending multiple personnel offshore. Group training can be more cost-effective and logistically convenient, particularly for companies mobilising crews for a new project. It is worth contacting your chosen provider directly to discuss scheduling, group rates, and whether dedicated course dates can be arranged to align with your project timeline.
