What is the OPITO Blended BOSIET course format?
The OPITO Blended BOSIET is one of the most widely recognised entry-level safety certifications for offshore workers worldwide. If you are preparing to work on an offshore installation for the first time, understanding the format of this course will help you know exactly what to expect before, during, and after your training.
What is the OPITO Blended BOSIET course?
The OPITO Blended BOSIET (Basic Offshore Safety Induction and Emergency Training) is a mandatory offshore safety course that combines online e-learning with hands-on practical training. It is designed for anyone who needs to work on an offshore oil and gas installation for the first time and has no prior offshore safety certification.
BOSIET is the globally recognised standard for initial offshore safety competence. The blended format was developed to make the certification more accessible and time-efficient by allowing participants to complete the theoretical knowledge components online before attending the physical training sessions. This approach reduces the time spent at a training centre without compromising the quality or depth of the safety content.
The course is accredited by OPITO, the global skills organisation for the energy industry, and the certificate is accepted by operators and employers across the North Sea, Gulf of Mexico, and other major offshore regions. You can explore the full range of OPITO HUET, FOET and BOSIET courses to find the right option for your situation.
How does the blended format of BOSIET work?
The blended BOSIET format splits the course into two distinct phases: an e-learning phase completed independently online, followed by a practical phase at a certified training centre. Participants must finish the e-learning modules before attending the practical sessions, as the classroom and pool activities build directly on the knowledge gained online.
This structure gives participants the flexibility to study at their own pace and schedule, which is particularly useful for contractors and freelancers who manage their own time. The practical phase is typically scheduled over one or two days at a physical training location, where certified instructors guide participants through emergency simulations, survival techniques, and equipment use.
The two phases work together to ensure that participants arrive at the training centre already familiar with the theory, allowing instructors to focus on building practical confidence and competence rather than covering basic concepts from scratch.
What is covered in the BOSIET e-learning modules?
The BOSIET e-learning modules cover the theoretical knowledge required for offshore emergency awareness and survival. Topics include the offshore working environment, hazard identification, personal survival techniques, firefighting principles, and the use of emergency equipment such as lifejackets and Compressed Air Emergency Breathing Systems (CA-EBS).
The online content is structured to be interactive and engaging, using scenarios, videos, and knowledge checks to reinforce learning. Participants work through modules covering:
- Offshore installation layout and emergency procedures
- Fire and gas hazard awareness
- Personal survival and sea survival principles
- Helicopter safety and emergency egress theory
- Use of personal protective and emergency equipment
- Communication and muster procedures
Completing these modules thoroughly prepares participants to make the most of the practical training days, as they will already understand the reasoning behind each procedure before they practise it in person.
What practical skills are trained during BOSIET?
The practical component of the Blended BOSIET focuses on hands-on emergency survival skills that cannot be taught effectively through online learning alone. These sessions take place at a certified training facility equipped with pools, fire simulation areas, and helicopter egress trainers.
During the practical phase, participants develop skills in the following sequence:
- Sea survival techniques, including jumping into water and staying afloat while wearing a lifejacket
- Helicopter Underwater Escape Training (HUET), including controlled inversion and egress from a submerged cabin
- Use of CA-EBS (Compressed Air Emergency Breathing System) during underwater egress
- Basic firefighting using handheld extinguishers
- Donning and using immersion suits and lifejackets correctly
- Liferaft boarding and survival procedures
These practical exercises are supervised by experienced instructors who ensure that each participant can perform the skills correctly and confidently. The training is designed to be realistic enough to build genuine competence while remaining safe for all participants.
Who needs to complete the OPITO Blended BOSIET?
The OPITO Blended BOSIET is required for any professional who will work on an offshore oil or gas installation and does not already hold a valid BOSIET or equivalent certification. This applies to first-time offshore workers across all roles, from engineers and technicians to catering staff and visitors.
Employers and offshore operators require this certification before granting access to an installation. It is not role-specific, meaning that the requirement applies regardless of your job function on the platform. If you are renewing an expired BOSIET, you would instead complete the FOET (Further Offshore Emergency Training) rather than repeating the full BOSIET.
The course is relevant to professionals working in the North Sea, the Gulf of Mexico, West Africa, the Middle East, and other offshore regions where OPITO standards are recognised. If you are unsure which version of the course applies to your location or employer requirements, contact FMTC Safety for guidance on the available formats.
How long does the Blended BOSIET take to complete?
The total duration of the Blended BOSIET is typically three to four days when combining both phases. The e-learning component takes approximately one to two days to complete, depending on your pace, and the practical training phase at a certified centre takes one to two days.
Compared to the traditional classroom-based BOSIET, which is usually delivered over three to four consecutive days entirely at a training centre, the blended format offers a meaningful time saving during the in-person phase. This is because the theoretical content is already covered before you arrive.
The e-learning can be completed in the weeks leading up to your practical training date, making it easier to fit the certification around work schedules or travel plans. Most training providers require proof of e-learning completion before you can attend the practical sessions, so it is important to plan ahead and allow enough time to finish the online modules comfortably.

Frequently Asked Questions
Can I start the BOSIET practical training before finishing all the e-learning modules?
No — completing the e-learning phase is a mandatory prerequisite before you can attend the practical training sessions. Most training providers, including FMTC Safety, will require proof of your e-learning completion before confirming your place on the practical days. This ensures you arrive at the training centre with the foundational knowledge needed to get the most out of the hands-on exercises.
What happens if I fail one of the practical assessments during BOSIET?
If you do not meet the required standard in a particular practical exercise, your instructor will typically provide additional guidance and give you the opportunity to attempt the skill again during the session. In cases where a participant is unable to complete a specific element, the training provider will advise on next steps, which may include rebooking that element of the course. It is worth speaking openly with your instructor throughout the training — they are there to build your confidence, not just assess you.
Is my OPITO Blended BOSIET certificate valid worldwide, or only in certain regions?
The OPITO BOSIET certificate is globally recognised and accepted by operators and employers across the North Sea, Gulf of Mexico, West Africa, the Middle East, and other major offshore regions. However, some specific locations or operators may have additional local requirements on top of the BOSIET, so it is always worth confirming with your employer or the offshore operator before travelling to a project. The core OPITO certification itself remains a universal baseline standard.
How long is the BOSIET certificate valid, and what do I need to do when it expires?
The OPITO BOSIET certificate is valid for four years from the date of issue. When it expires, you do not need to repeat the full BOSIET course — instead, you complete the FOET (Further Offshore Emergency Training), which is a shorter refresher course designed to update and revalidate your offshore safety competence. It is important to track your certificate's expiry date carefully, as offshore operators will not grant installation access with an expired certification.
Do I need to be physically fit to complete the BOSIET, and are there any medical requirements?
Yes, participants are required to meet certain medical fitness standards before attending BOSIET training, particularly for the water-based and HUET exercises. You will typically need a valid offshore medical certificate (such as an OGUK/UKOOA medical) before booking your practical sessions. If you have any pre-existing medical conditions, disabilities, or concerns about the physical demands of the course, it is strongly recommended to speak with your training provider in advance, as reasonable adjustments may be available in some circumstances.
What should I bring or prepare before attending the practical training days?
For the practical phase, you should bring your proof of e-learning completion, a valid form of photo ID, and your offshore medical certificate. Wear comfortable clothing suitable for physical activity, as you will be getting wet during the pool-based exercises — swimwear or suitable underlayers are recommended, and towels are worth packing. Your training provider will send a full joining instructions document ahead of your course date, so make sure to read it carefully and contact them if anything is unclear.
Can my employer book BOSIET training for a group of workers, and are there any advantages to group bookings?
Yes, training providers like FMTC Safety cater to both individual professionals and organisations looking to certify teams. Group bookings can simplify the administrative process significantly, with coordinated scheduling, consolidated invoicing, and the ability to align training dates with project mobilisation timelines. If you are responsible for workforce compliance, speaking directly with the training provider about your team's numbers and timeline will help you find the most efficient and cost-effective arrangement.
