How do new offshore workers choose between BOSIET and BOSIET with CAEBS?

New offshore workers should choose BOSIET with CAEBS if their work involves helicopter travel to installations where compressed air emergency breathing systems are available. The key deciding factor is the type of helicopter operations at their destination. If the operator or client specifies CAEBS-equipped flights, the upgraded certification is mandatory, not optional. This article walks through the most common questions new starters ask when deciding between the two.

What is the difference between BOSIET and BOSIET with CAEBS?

BOSIET stands for Basic Offshore Safety Induction and Emergency Training. It is the foundational offshore safety training certification required for anyone working offshore for the first time. BOSIET with CAEBS includes everything in the standard course, plus training on how to use a compressed air emergency breathing system during a helicopter underwater escape.

A CAEBS unit is a small breathing device worn by passengers during helicopter flights over water. It provides a short supply of breathable air, giving passengers additional time to escape a submerged helicopter cabin. The CAEBS module teaches workers how to activate and use this device correctly under pressure, in a controlled underwater environment.

Both certifications are accredited by OPITO, the globally recognized body for offshore safety competency standards. The core survival skills, firefighting elements, first aid awareness, and helicopter underwater escape training (HUET) are identical in both courses. The only addition in the CAEBS version is the practical breathing system exercise.

When is BOSIET with CAEBS required instead of standard BOSIET?

BOSIET with CAEBS is required when the helicopter operator or offshore client mandates CAEBS use on their flights. This is typically determined by the specific installation, the operating region, or the helicopter type in use. Many operators in the North Sea, for example, require CAEBS certification as a standard condition of travel.

The clearest way to find out which version you need is to check directly with your employer, contractor, or the offshore operator managing the project. Your mobilization documentation or crew management team will usually specify which certification is required before you can travel to the installation.

As a general rule, if you are heading to a UK, Norwegian, or Dutch sector installation, CAEBS is commonly required. For other regions, requirements vary. Always confirm before booking.

Does BOSIET with CAEBS cost more and take longer to complete?

Yes, BOSIET with CAEBS is slightly more expensive and takes a little longer than the standard BOSIET. The additional cost reflects the extra equipment, pool time, and instructor resources needed for the compressed air breathing exercise. The time difference is typically a matter of hours rather than an additional full day.

Both versions of the course are multi-day programs. The CAEBS addition is integrated into the existing schedule rather than added as a separate module at the end, so the overall structure remains manageable. For most workers, the price and time difference are modest compared to the certification value it delivers.

Can you upgrade from BOSIET to BOSIET with CAEBS later?

Yes, it is possible to add CAEBS training after completing a standard BOSIET. OPITO offers a standalone HUET with CAEBS module for certified workers who need to upgrade their qualification without repeating the full course. This is a practical option if your work situation changes and a new client or operator requires CAEBS certification.

However, there are some important points to keep in mind:

  • The standalone HUET with CAEBS upgrade is only available to workers who already hold a valid BOSIET or FOET certificate.
  • Your existing certificate must still be within its validity period to qualify for the upgrade path.
  • If your BOSIET has expired, you will need to complete a full FOET (Further Offshore Emergency Training) with CAEBS rather than a simple upgrade.
  • Not all training centers offer the standalone upgrade, so it is worth confirming availability when booking.

If you are just starting out and know that CAEBS will be required for your work, booking BOSIET with CAEBS from the beginning is the more efficient and cost-effective route.

Which certification should a new offshore worker book first?

If you already know which installation or operator you are working for, book the certification they require. If CAEBS is specified, go straight for BOSIET with CAEBS. If you are still in the early stages of your offshore career and do not yet have a confirmed project, booking BOSIET with CAEBS is the safer choice because it covers more requirements and avoids the need for an upgrade later.

Here is a simple decision process to follow:

  1. Check your mobilization documents or ask your employer which certification is required.
  2. If CAEBS is specified or likely, book BOSIET with CAEBS directly.
  3. If no specification is given and you are unsure, contact the training provider or your crewing team before booking.
  4. If you are booking independently without a confirmed project, choose BOSIET with CAEBS for broader coverage.
  5. Confirm your training location and start date well in advance to avoid delays to your mobilization.
