What OPITO courses do you need for your first offshore job?

To start your first offshore job, you need at least one core OPITO certification: the Basic Offshore Safety Induction and Emergency Training, better known as BOSIET. This course covers the essential safety and emergency skills required before you can set foot on an offshore installation. Depending on your destination region and employer, additional OPITO courses may also be required.

Below, we answer the most common questions about OPITO training requirements so you know exactly what to arrange before your first offshore assignment.

Which OPITO courses are mandatory for offshore work?

The BOSIET is the mandatory baseline for virtually all first-time offshore workers. It covers helicopter underwater escape training (HUET), sea survival, firefighting, and first aid. Without a valid BOSIET, most operators will not allow you access to an offshore installation. Some operators also require additional certifications depending on the role or location.

The most commonly required OPITO courses for offshore work include:

• BOSIET (Basic Offshore Safety Induction and Emergency Training) — the standard entry-level requirement
• HUET (Helicopter Underwater Escape Training) — sometimes taken as a standalone refresher
• FOET (Further Offshore Emergency Training) — the renewal course once your BOSIET expires
• T-BOSIET (Tropical BOSIET) — required for certain warmer climate regions
• MIST (Minimum Industry Safety Training) — required for some UK North Sea operations

Always confirm the exact requirements with your employer or operator before booking, as specific project or platform requirements can vary.

What is the difference between BOSIET and FOET?

The BOSIET is for first-time offshore workers who have never held an OPITO certification before. The FOET is the renewal course for workers whose BOSIET has expired or is approaching expiry. Both courses cover emergency response, helicopter escape, and sea survival, but the FOET is shorter and assumes prior offshore safety knowledge.

In practical terms: if you are preparing for your first offshore job, you need the BOSIET. Once that certificate expires, you complete a FOET renewal to maintain your certification. The FOET is not a replacement for the BOSIET for new entrants. It is specifically designed as a refresher for experienced offshore workers keeping their credentials current.

Do OPITO requirements change depending on the region or operator?

Yes, OPITO training requirements do vary by region and operator. The standard BOSIET is accepted across most global offshore locations, but certain regions require region-specific versions. For example, tropical regions such as West Africa, Southeast Asia, or the Middle East often require the T-BOSIET (Tropical BOSIET) instead of or in addition to the standard version.

Individual operators also set their own requirements on top of the OPITO baseline. Some may require additional courses in first aid, firefighting, or specific technical safety topics. It is always worth checking the operator’s mobilisation requirements or asking your agency or employer directly before you book your training.

How long does it take to complete OPITO training for offshore work?

The BOSIET typically takes two to three days to complete, depending on the training provider and whether it includes the CA-EBS (Compressed Air Emergency Breathing System) component. The course combines classroom theory, practical exercises, and pool-based helicopter escape training, so it requires multiple sessions across consecutive days.

If you need additional courses such as the T-BOSIET or supplementary e-learning modules, plan for extra time. Most workers preparing for their first offshore job complete their OPITO training within a week. To avoid delays to your project start date, book your training as early as possible, ideally several weeks in advance.

How long are OPITO certificates valid before they expire?

Most OPITO certificates, including the BOSIET, are valid for four years. After that, you must complete the FOET to renew your certification. Some components, such as first aid, may have shorter validity periods and require separate renewal.

Keeping track of your certificate expiry dates is essential. An expired certificate can prevent you from mobilising to a project, which can have significant consequences for both you and your employer. Many offshore professionals set calendar reminders well ahead of their expiry date to ensure they complete renewal training in time. You can explore the full range of OPITO HUET, FOET and BOSIET courses to find the right option for your situation.

Where can you take OPITO-approved courses before going offshore?

OPITO-approved courses must be completed at an accredited training centre. These centres are audited and approved by OPITO to ensure the training meets the required standard. When choosing a provider, look for OPITO accreditation, practical facilities including a pool for HUET training, and convenient scheduling options.

Training centres are often located near major ports, airports, or offshore industry hubs to make it easier for workers to complete their certification before travelling to a project. Check that your chosen provider offers guaranteed course dates, flexible cancellation policies, and clear documentation of your certificates after completion.
