OPITO is not a training provider — it is a standards body. Every BOSIET, FOET, HUET, MIST and T-BOSIET certificate held by an offshore worker traces back to an OPITO standard delivered at an OPITO-accredited training centre. Understanding what OPITO is, how it accredits centres, and how to verify a certificate is essential for both workers managing their own qualifications and employers verifying others'.

What OPITO is, and what it does

OPITO was founded in 1977 as the skills body for the UK offshore oil and gas industry. Its founding remit was to establish, maintain and develop a single set of safety and technical training standards that every offshore operator could rely on — replacing the fragmented patchwork of company-specific training requirements that previously existed.

Over the next four decades OPITO expanded internationally. Today OPITO standards are recognised by oil and gas operators across the North Sea, Gulf of Mexico, West Africa, the Middle East, Asia-Pacific and South America. OPITO is the de facto global qualification standard for offshore safety training. The organisation remains a not-for-profit, funded by the industry it serves.

OPITO's core activities are: (1) defining standards — publishing the technical and assessment requirements for each safety qualification; (2) accrediting training centres — auditing centres against the standards and granting/maintaining accreditation; (3) maintaining a certificate register — running the global verification system that lets any party look up a certificate; (4) developing new standards — adapting the library as industry safety practice evolves (the CA-EBS migration in BOSIET is a recent example).

The most common OPITO standards

Out of ~100 active OPITO standards, the ones held by the broadest population of offshore workers are:

How OPITO accreditation works

A training centre cannot simply decide to deliver an OPITO course. It must apply for accreditation against each specific standard it wants to deliver. The process is rigorous and ongoing.

  1. 1.
    ApplicationTraining centre submits an application to OPITO covering the specific standard, target delegate volume, instructor qualifications, facilities and equipment.
  2. 2.
    AuditOPITO conducts an on-site audit — checking equipment (HUET simulator, fire-fighting trainer, lab equipment etc.), reviewing instructor qualifications and recent CPD, observing course delivery, examining assessment records and quality management systems.
  3. 3.
    Accreditation decisionOPITO grants accreditation if the centre meets the standard; centres with minor findings may be granted accreditation with conditions; centres failing significantly are rejected and may reapply after improvement.
  4. 4.
    Ongoing surveillanceAccredited centres are re-audited on a routine cycle (typically annually). OPITO can suspend or revoke accreditation if standards slip. The list of currently-accredited centres is published on the OPITO website.

How to verify an OPITO certificate

OPITO maintains a global certificate-verification system on its official website. The process for an employer or third party to verify a worker's certificate:

  1. 1.Obtain the OPITO certificate number from the worker (printed on the certificate).
  2. 2.Go to opito.com and locate the certificate-verification tool.
  3. 3.Enter the certificate number and the worker's name / date of birth (verification requires multiple data points to prevent fraud).
  4. 4.The system returns: certificate validity, expiry date, course name, accredited centre that issued it.

The OPITO certificate-verification system is the canonical proof-of-currency for offshore workers. Forged or expired certificates can be identified in seconds. This is one of the primary reasons OPITO standards are trusted globally — the verification infrastructure is real and works.

Regional recognition

UK North Sea

Fully recognised — OPITO standards are the baseline.

Norwegian Continental Shelf

Widely accepted; NORSOK GSK is the national equivalent and is sometimes required alongside.

US Gulf of Mexico

Accepted by most operators; SAFEGulf or RigPass are domestic equivalents that some operators specify additionally.

West Africa

Widely accepted across Nigeria, Angola, Ghana — particularly by IOC operators (Total, Shell, Chevron, ExxonMobil).

Middle East

Widely accepted; some national operators (Saudi Aramco, ADNOC, QatarEnergy) maintain additional national induction requirements.

Asia-Pacific

Accepted across Australia, Malaysia, Indonesia, Vietnam; MARCSTA is the Australian national equivalent.

South America

Accepted across Brazil, Guyana, Trinidad; Petrobras-led market often requires CBSP (Curso Básico de Sobrevivência no Mar) alongside.

Find an OPITO-accredited training centre

OPITO accredits training centres rather than delivering training itself. The opito.com website maintains the canonical, continuously-updated list of every accredited centre worldwide, searchable by country and by OPITO standard (BOSIET, FOET, HUET, MIST, T-BOSIET, etc.). The OPITO list is the authoritative source — bookings should always reference it before paying for a course.

Frequently asked questions

What is OPITO?↓
OPITO is the Offshore Petroleum Industry Training Organisation — a global, not-for-profit body that defines technical and safety training standards for the offshore oil and gas industry. Founded in 1977, OPITO is the de facto global certification authority for offshore safety qualifications including BOSIET, FOET, HUET, MIST, T-BOSIET, OGUK Medical (industry-aligned) and around 100 other standards. OPITO does not deliver training itself — it sets the standard and approves the training centres that deliver courses to that standard.
How does OPITO accreditation work?↓
OPITO publishes detailed technical standards for each qualification (e.g. Standard 5700 for BOSIET with EBS). Training centres apply to OPITO to deliver a specific standard at their facility. OPITO audits the centre — instructors, equipment, facilities, assessment procedures, quality management — and grants accreditation if the centre meets the standard. Accredited centres can then issue OPITO-recognised certificates to learners who complete the course. OPITO maintains an ongoing audit programme to ensure standards are upheld over time.
How do I verify an OPITO certificate?↓
OPITO maintains a global certificate-verification system on its official website (opito.com). Employers, operators and other interested parties can look up a certificate by its OPITO number and confirm: certificate validity, expiry date, course completed, training centre that issued it. This is the canonical way for employers to verify a worker's OPITO credentials before mobilisation. Workers receive their OPITO number on the certificate itself.
What are the most common OPITO standards?↓
The most widely-held OPITO certifications worldwide are: BOSIET (Basic Offshore Safety Induction and Emergency Training, OPITO 5700/5800 series); FOET (Further Offshore Emergency Training, the BOSIET refresher); HUET (Helicopter Underwater Escape Training, often delivered standalone); MIST (Minimum Industry Safety Training, OPITO 5301); T-BOSIET (Tropical BOSIET, for warm-water operations); and various specialised standards for crane operators, banksmen, helideck operators, and rigging. OPITO's full standards library contains around 100 active standards.
Is OPITO certification recognised globally?↓
Yes — OPITO is the de facto global standard. OPITO-issued certificates are accepted by major operators in the North Sea, Gulf of Mexico, West Africa, the Middle East, Asia-Pacific, Australia and South America. Some regions maintain national equivalents (NORSOK in Norway, SAFEGulf in the US Gulf of Mexico, MARCSTA in Australia) that operate alongside or sometimes in place of OPITO standards; OPITO certificates are usually still accepted by international operators in these regions. Always confirm with the specific operator before relying on OPITO certification in a new basin.
Does OPITO issue certificates directly?↓
No. OPITO sets standards and accredits training centres; the certificates themselves are issued by the OPITO-accredited centre that delivers the course. The certificate carries the OPITO logo and standard number, and the OPITO certificate number — but the issuing party is the training centre. OPITO maintains the central register that lets anyone verify the certificate.
Can I take an OPITO course online?↓
Some OPITO standards permit digital-delivery components for theory portions of the course, but practical assessments — pool work for HUET, fire-suppression drills for BOSIET, simulator exercises for well control — must be completed in person at an OPITO-accredited centre. MIST is the main OPITO standard that supports a fully-online renewal pathway for workers who already hold a valid existing MIST certificate. Pre-course theory modules are increasingly online across many OPITO standards.
