What physical requirements are needed for BOSIET training?

If you work in the offshore industry or plan to, BOSIET training is one of the first certifications you will need to complete. The course covers critical survival skills for helicopter emergencies at sea, which means it involves real physical challenges in and around water. Before you book your course, it is worth understanding exactly what the physical requirements are and whether you are ready to meet them.

What is BOSIET training and who needs it?

BOSIET stands for Basic Offshore Safety Induction and Emergency Training. It is a mandatory OPITO-certified course designed for anyone who travels to or works on offshore installations by helicopter. The training covers helicopter underwater escape, sea survival, firefighting, and first aid fundamentals.

Anyone entering the offshore oil, gas, or wind energy sectors for the first time typically needs a valid BOSIET certificate. This includes engineers, technicians, contractors, and support staff who will be transported to offshore platforms. In many cases, you cannot board a helicopter to an offshore location without it. The OPITO HUET, FOET & BOSIET courses cover several variants depending on your specific role and destination, including tropical versions for warmer climates.

What are the physical requirements for BOSIET training?

BOSIET training has specific physical requirements because participants must complete water-based exercises, including a helicopter underwater escape simulation. You must be able to enter and exit the water safely, hold your breath briefly, and follow physical instructions under simulated stress. Most training providers require participants to meet a basic fitness standard before attending.

The standard physical requirements for BOSIET typically include:

• Being able to enter water from a height without assistance
• Remaining afloat unaided for a short period
• Completing the HUET (Helicopter Underwater Escape Training) module, which involves being submerged and inverting in a simulator
• Wearing and inflating a lifejacket correctly in the water
• Participating in sea survival exercises, including boarding a life raft
• Completing basic firefighting tasks, which involve physical effort and heat exposure

You do not need to be an athlete, but you do need a reasonable level of general fitness. The exercises are designed to reflect real emergency scenarios, so the physical demands are genuine.

What medical conditions can disqualify you from BOSIET?

Certain medical conditions may prevent you from safely completing BOSIET training. Because the course involves submersion, physical exertion, and stress-inducing scenarios, conditions that affect breathing, cardiovascular function, or mobility can pose serious risks to the participant and others around them.

Conditions that may disqualify you from BOSIET include:

1. Epilepsy or seizure disorders that are not fully controlled by medication
2. Severe asthma or respiratory conditions that could be triggered by water exposure or physical exertion
3. Uncontrolled cardiovascular conditions such as recent heart surgery or serious arrhythmias
4. Claustrophobia that is severe enough to prevent participation in the HUET simulator
5. Recent surgeries or injuries that limit mobility or make water entry unsafe
6. Ear conditions such as perforated eardrums, which can be affected by submersion

Before attending your course, you will typically need to complete a medical self-declaration form. For some conditions, a formal medical fitness certificate from a qualified offshore medical examiner may be required. If you are unsure whether your health situation is compatible with the training, consulting a medical professional in advance is strongly recommended.

Do you need to be able to swim to complete BOSIET?

You do not need to be a strong swimmer to complete BOSIET training, but you must be water confident. Participants are required to enter the water and float with the assistance of a lifejacket, so the ability to remain calm in the water is essential. Strong swimming ability is not tested, but comfort in an aquatic environment is necessary.

During the course, you will wear a lifejacket for most water-based exercises, which provides buoyancy. The HUET module does involve brief submersion and inversion, but instructors are present at all times and safety divers are on standby. If you have a genuine fear of water rather than just limited swimming skill, it is worth discussing this with the training provider before you attend.

How do you prepare physically for BOSIET training?

Preparing physically for BOSIET training does not require an intense fitness programme, but some targeted preparation will help you get the most out of the course and reduce anxiety on the day. The goal is to arrive feeling comfortable with water and physically capable of completing moderate exertion tasks.

Practical steps to prepare include:

• Spending time in a swimming pool to build water confidence, even if you are not swimming laps
• Practising holding your breath briefly in a controlled setting
• Ensuring any recent injuries are healed and cleared by a doctor before attending
• Getting adequate sleep in the days before the course, as fatigue affects both physical and mental performance
• Disclosing any health concerns honestly on your pre-course medical declaration

If you have not been active recently, light cardiovascular exercise in the weeks before your course can help you handle the firefighting and emergency response modules more comfortably.

What happens if you don’t meet the BOSIET physical requirements?

If you do not meet the physical requirements for BOSIET training, you may not be permitted to complete certain modules or the full course. In some cases, participants are asked to sit out specific exercises if a medical or physical concern arises on the day. This is done for your safety and the safety of others in the group.

If you are removed from a module or cannot complete the full course, you will not receive your BOSIET certificate, as all components are mandatory for certification. This means you would need to rebook and attend again once the issue is resolved.

It is always better to address any physical or medical concerns before the course rather than on the day. Providers typically allow free cancellation or rescheduling within a reasonable window, so if your health situation changes before your course date, contacting the provider promptly gives you the most flexibility.
