BOSIET with CA-EBS (OPITO standard 5750) is 20 hours 40 minutes of guided learning, which centres usually run over three days, and the certificate is valid for four years. Seaman Books arranges your enrolment from our Business Bay, Dubai office. We check that you’re booking the right course code, find an OPITO-approved centre with a seat, and confirm the centre’s fee in writing before you pay. The centre delivers the training and issues the certificate.

BOSIET, HUET and FOET at a glance
| Course | OPITO code | Guided learning | Who books it |
|---|---|---|---|
| BOSIET with CA-EBS | 5750 | 20 hrs 40 mins (usually 3 days) | First-time offshore workers, cold and temperate regions |
| FOET with CA-EBS (refresher) | 5850 | 8 hrs (usually 1 day) | Holders of an in-date BOSIET or FOET |
| HUET with CA-EBS | 5295 | 7 hrs 10 mins | Helicopter escape only, where the operator requires nothing more |
| Tropical BOSIET (T-BOSIET) | 5501 | 19 hrs | First-time offshore workers in tropical regions |
| Tropical FOET (T-FOET) | 5614 | 7 hrs | Holders of an in-date T-BOSIET or T-FOET |
Guided learning hours are OPITO’s published figures. Daily schedules are set by each centre, not by OPITO. OPITO sets a maximum four-year interval between BOSIET (5750) and the FOET refresher (5850), and the same interval between T-BOSIET (5501) and T-FOET (5614). Your duty holder can set a shorter one.

Which one do you need? Your operator or contractor’s mobilisation letter names it. If it says “BOSIET” and your current certificate is still valid, you almost certainly need FOET, the one-day refresher, not the full three-day course. If your BOSIET has already expired, FOET is no longer open to you. Still deciding? Read BOSIET vs HUET: which offshore course do you need, or send us the letter and we’ll read it for you.
What a BOSIET course in Dubai costs
Course fees are set by each approved centre, not by OPITO and not by Seaman Books. The fee depends on the centre, the variant (CA-EBS or Tropical) and the intake date. Our coordination charge is quoted separately and itemised, so you can see which part goes to the centre and which part is ours.
Before anything is booked, you get the centre’s fee, the course dates and our charge in writing. Nothing is paid until you approve it.
How to book BOSIET from Dubai: four steps
- Send three things on WhatsApp: your name exactly as it appears in your passport and seaman book, your current OPITO certificate number and expiry date (if you hold one), and the course named in your mobilisation letter.
- We check the code and the timing. BOSIET when you need FOET, or CA-EBS when the operator wants Tropical: picking the wrong one means paying for a second course. We also check the booking window (below).
- We find a seat. We look for an OPITO-approved centre with availability that matches your joining date, and confirm the fee with you.
- You attend; the centre certifies. Bring your passport, your medical and any previous OPITO certificate. Check your new certificate on OPITO’s public certificate validation page with your surname and certificate number.
Book inside the last three months, not earlier
OPITO dates a renewal from your old expiry date, not the course date, if you train within the three months before expiry (90 days on the HUET standard). Book earlier and the new four years start on the day you train, so the remaining months on your old certificate are lost.
Book later, after expiry, and it costs more. FOET requires a valid, in-date certificate, so a lapsed BOSIET means sitting the full 20-hour-40-minute course again. OPITO publishes no grace period.
From Dubai, the practical rule: message us about four months before expiry so there is a confirmed seat inside the three-month window. More detail: HUET renewal requirements.
Before you book: medical and fitting
- Medical. OPITO accepts a current offshore medical, an employer-approved equivalent, a fitness-to-work-at-sea certificate, a diving medical, or a medical screening form issued by the approved centre. Many seafarers qualify on their existing flag-state medical; have it checked before you travel. See OEUK offshore medical certificate.
- Shoulder-breadth measurement. Some duty holders require an OPITO shoulder-breadth measurement (standard 9365) before helicopter travel. Check your mobilisation letter; if it is listed, tell us when you book.
- Name match. The name on your certificate should match your passport and seaman book exactly. A mismatch causes rejections across your whole file.
Why seafarers in Dubai and the GCC book through us
We’re in Business Bay, Dubai, and have supported more than 10,000 seafarers since 2011. ISO 9001:2015 certified.
One file for the whole mobilisation. Offshore crew usually need more than one certificate renewed in the same window. While your course is booked, we can check your seaman book renewal and your STCW basic safety (see STCW courses in Dubai), so nothing expires mid-hitch. The documents you’ll carry in the region are listed in top 3 documents every offshore worker in the GCC must carry.
Not in Dubai? Seafarers in Abu Dhabi, Sharjah, Fujairah, Oman, Qatar and Saudi Arabia arrange the whole process with us over WhatsApp and email. You travel only for the course itself.

Frequently asked questions
Can I do a BOSIET course in Dubai?
BOSIET must be taken at an OPITO-approved centre. We find the nearest approved centre with a seat that matches your joining date and handle the booking from Dubai.
How many days is a BOSIET course?
BOSIET with CA-EBS (OPITO 5750) is 20 hours 40 minutes of guided learning, which centres usually schedule over three days. The FOET refresher is 8 hours, usually one day. Tropical BOSIET is 19 hours.
How long is a BOSIET certificate valid?
Four years. OPITO sets a maximum four-year interval between BOSIET and the FOET refresher, and your duty holder can set a shorter one. If you take FOET within three months before expiry, the new certificate is dated from your old expiry date, so no validity is lost.
My BOSIET has expired. Can I still do FOET?
No. FOET requires a valid, in-date BOSIET or FOET certificate. Once yours has expired, you have to retake the full BOSIET. OPITO publishes no grace period.
Does BOSIET include HUET?
Yes. BOSIET includes helicopter underwater escape training. Standalone HUET (5295, 7 hours 10 minutes) is for people who need helicopter transfer training without the full BOSIET. Your operator decides which it requires.
How much does BOSIET cost in Dubai?
Each approved centre sets its own fee; OPITO and Seaman Books don’t. We confirm the centre’s fee and our coordination charge in writing before anything is booked.
How do I check that my OPITO certificate is genuine?
Use OPITO’s free public validation page at thehubopito.com/public/validate. Enter your surname and the certificate reference. Do this the week you receive a certificate, not the week you need it.
Does Seaman Books run the training?
No. Seaman Books is a documentation and enrolment consultancy. We arrange the booking; an OPITO-approved centre delivers the training and issues the certificate.
