How do you know if you need BOSIET or FOET?

Whether you need BOSIET or FOET depends on where you are in your offshore career. If you have never completed offshore survival training before, you need BOSIET. If you already hold a valid BOSIET certificate and it is approaching its expiry date, you need FOET to renew it. These two OPITO-certified courses serve different stages of the same certification journey.

Both courses are mandatory for anyone working offshore, and choosing the wrong one can mean delays to your project or having to rebook. The sections below break down the key differences, validity periods, and what to do if your certificate has already expired.

What’s the difference between BOSIET and FOET?

BOSIET stands for Basic Offshore Safety Induction and Emergency Training. It is the entry-level offshore survival course required before you set foot on an offshore installation for the first time. FOET stands for Further Offshore Emergency Training, and it is the refresher course you take to renew your BOSIET certification before it expires. BOSIET is the foundation; FOET is the renewal.

The two courses share similar content because FOET is designed to refresh and reinforce the skills learned in BOSIET. However, BOSIET is typically longer and more intensive, as it introduces participants to offshore emergency procedures from scratch. FOET assumes you already have that baseline knowledge and focuses on keeping your skills current and sharp.

Both courses are accredited by OPITO, the globally recognized body for offshore safety training standards. Completing either course results in an OPITO certification that is accepted by operators worldwide.

Who needs BOSIET and who needs FOET?

You need BOSIET if you are entering the offshore industry for the first time and have no previous OPITO offshore survival certification. You need FOET if you already hold a BOSIET certificate that is still valid and you want to renew it before it expires. Your employer, contractor, or the offshore operator will typically specify which course is required before mobilization.

In practice, this means:

• New entrants to the offshore sector always start with BOSIET
• Experienced offshore workers renewing an active certificate take FOET
• Workers whose certificate has already expired may need to retake BOSIET rather than FOET
• Some operators or regions may have additional requirements on top of the standard OPITO course

If you are unsure which course applies to your situation, check with your employer, crewing agent, or the operator you are working for. They will confirm exactly what documentation is required before you travel to a project.

How long is a BOSIET certificate valid?

A BOSIET certificate is valid for four years from the date of completion. This applies to the standard BOSIET as well as the T-BOSIET, which is the tropical variant designed for workers heading to warmer climate offshore environments. After four years, the certificate expires and must be renewed through FOET.

Keeping track of your expiry date is important, especially if you work on multiple projects across different operators. Many offshore professionals build in a buffer and book their FOET renewal several months before the certificate actually expires, so there is no risk of being unable to mobilize due to an out-of-date certification.

What happens if your BOSIET certificate expires?

If your BOSIET certificate has expired, you are generally not eligible to take FOET as a renewal course. Instead, you will likely need to retake the full BOSIET course to regain your certification. This is because FOET is designed as a refresher for those with a current, active certificate, not as a course to reinstate lapsed qualifications.

The exact rules can vary slightly depending on the operator, the country, or the specific project requirements. Some operators may have a short grace period or specific guidance for workers with recently expired certificates. However, as a general rule, do not let your certificate lapse if you want to avoid the time and cost of completing the full BOSIET again.

If you are in this situation, the safest step is to contact your employer or a certified training provider directly to confirm what is required before booking.

Does FOET cover the same content as BOSIET?

FOET covers much of the same subject matter as BOSIET, but it is structured as a refresher rather than an introduction. Both courses include helicopter underwater escape training (HUET), sea survival, firefighting, and first aid. The key difference is that FOET is shorter and assumes participants already have a working knowledge of offshore emergency procedures from their initial BOSIET training.

BOSIET is designed to build competence from the ground up. FOET is designed to maintain and reinforce that competence over time. This is why FOET is only available to those who already hold a valid certification. If you completed your BOSIET four years ago, FOET brings your knowledge and practical skills back up to the required standard.

Both courses are available in standard and tropical variants. The T-FOET is the refresher equivalent of T-BOSIET and is required for workers returning to tropical offshore environments.

Where can you take BOSIET or FOET training?

BOSIET and FOET training must be completed at an OPITO-approved training center. These centers are located across the globe, with concentrations near major offshore industry hubs such as ports, airports, and energy industry regions. Choosing a training location that is convenient to your departure point or home base makes it easier to complete your certification before heading to a project.

When selecting a training center, look for:

1. OPITO accreditation for the specific course you need
2. A location that is accessible from your home or work base
3. Flexible scheduling options, including guaranteed course dates
4. Clear booking and cancellation policies
5. The ability to book both BOSIET and FOET variants, including tropical versions if needed

Training centers near airports or ports are particularly practical for offshore professionals who need to complete their certification and travel to a project in the same trip. You can view our available training locations to find a center that works for your schedule and location.
