How long is a HUET course?

A HUET course typically takes one day to complete, with most programs running between 6 and 8 hours, including both classroom instruction and practical water exercises. The exact HUET course duration can vary slightly depending on the training provider, the specific OPITO standard being followed, and whether additional modules such as Compressed Air Emergency Breathing Systems (CA-EBS) are included. This article covers everything you need to know about HUET training length, certificate validity, renewal timing, and who is required to complete it.

What does a HUET course actually involve?

A HUET course, short for Helicopter Underwater Escape Training, is a practical safety course that teaches offshore workers how to escape from a helicopter that has ditched into the sea. It combines theory with hands-on exercises in a purpose-built pool environment, using a helicopter simulator that can invert underwater to replicate a real emergency scenario.

The course covers the following core elements:

• Helicopter safety briefings and pre-flight procedures
• Understanding helicopter ditching and underwater orientation
• Breathing techniques and breath-holding exercises
• Practical escape from an inverted helicopter simulator
• Use of CA-EBS (Compressed Air Emergency Breathing System) if included
• Sea survival awareness and post-ditching procedures

The practical component is what makes HUET training genuinely effective. Participants do not just watch demonstrations; they perform multiple underwater escape exercises themselves, building the muscle memory and calm response needed in a real emergency.

How many hours does a HUET course take to complete?

A HUET course takes approximately 6 to 8 hours to complete, meaning it is typically delivered as a full single-day program. The classroom or theory portion usually takes 1 to 2 hours, while the practical poolside exercises account for the majority of the training time.

If the course includes a CA-EBS (Compressed Air Emergency Breathing System) module, the total HUET training length may extend slightly to accommodate additional practical drills with the breathing device. Some providers also offer HUET as a standalone refresher within a broader course such as FOET (Further Offshore Emergency Training), which may affect the overall schedule.

The OPITO-accredited HUET with CA-EBS is the most commonly required version for offshore professionals, and completing it within a single day makes it straightforward to fit around travel and project schedules.

How long is a HUET certificate valid for?

A HUET certificate is valid for 4 years from the date of completion. This validity period applies to OPITO-accredited HUET certifications, which are the internationally recognized standard used across the offshore oil, gas, and wind sectors.

It is worth noting that the 4-year validity assumes no significant gap in offshore work. Some operators or project-specific requirements may impose shorter validity windows, so it is always worth checking with your employer or contracting company before assuming your certificate is still accepted on a specific installation or vessel.

When do you need to renew your HUET training?

You need to renew your HUET training before your certificate expires, ideally scheduling your refresher course a few weeks before the 4-year expiry date. Waiting until the last moment risks delays if course availability is limited, which could affect your ability to mobilize to a project on time.

Here is a simple approach to managing your HUET renewal:

1. Note your certificate expiry date as soon as you complete your initial training
2. Set a reminder 3 to 4 months before expiry to begin looking at available course dates
3. Book your refresher course well in advance, especially during busy offshore mobilization seasons
4. Check whether your employer or project requires the full HUET or a broader refresher such as FOET with CA-EBS
5. Confirm your new certificate is uploaded and accessible in your training records before travel

If your HUET certificate has already expired, you will need to retake the full course rather than a shorter refresher. Staying ahead of your expiry date is always the better option.

Who needs to complete HUET training?

HUET training is required for anyone who travels to or from an offshore installation by helicopter. This includes offshore oil and gas workers, wind technicians working on offshore wind farms, maritime crew, contractors, engineers, and any other personnel who are transported by helicopter as part of their role.

In practice, HUET is a mandatory requirement across most offshore sectors globally. Whether you are working on a fixed platform in the North Sea, a floating production unit, or an offshore wind installation, helicopter underwater escape training is a non-negotiable part of your safety certification. It is typically required alongside other OPITO courses such as BOSIET or FOET, which form the broader offshore survival training package. You can explore the full range of OPITO HUET, FOET and BOSIET courses to understand which combination applies to your role.
