How to Become an Offshore Welder in the UK

Start with welding competence and experience that match the job, then check the offshore training and medical evidence the employer accepts. Welding above water on a platform is not the same career route as commercial diving. Before paying for certificates, choose the type of work you want and ask a recruiter what is actually missing from your application.

Choose topside welding or commercial diving first

“Offshore welder” can describe different jobs. Topside work means welding above water; underwater welding involves diving at work. A recreational diving course or an offshore survival certificate does not qualify you as a commercial diver.

For working divers in Great Britain, HSE requires an approved qualification suitable for the work, competence and medical fitness to dive. Read its route guidance before considering that separate career. Ask the employer which jurisdiction and diving rules apply; do not assume a topside welding route qualifies you for saturation diving.

Build welding experience before buying an offshore package

The National Careers Service welder profile describes college, apprenticeship and trainee routes in England. If you are new, compare local fabrication or welding opportunities and how you will gain supervised practical experience. Different UK nations have their own training arrangements.

If you already weld, read several relevant adverts. Note the process, material, plate or pipe work, drawings and inspection requirements. Keep evidence of work you have actually done, rather than listing every welding method as a skill. Onshore experience is preparation, not a guaranteed offshore placement.

What a coded welding test actually proves

Ask which welder qualification the contract requires. TWI explains welder and procedure approval, including BS EN ISO 9606 and ASME Section IX. The job and applicable standard determine the required approval; there is no single “offshore welding ticket” for every process and material.

Before paying for a test, confirm its scope and the evidence needed to keep the certificate valid. A course attendance certificate is not proof that you hold the approval an employer needs. Ask the employer or examining body to check your existing certificate against the actual work.

Oil and gas safety training is not a universal offshore licence

OPITO’s BOSIET with CA-EBS is initial safety and emergency-response training for people entering or returning to offshore oil and gas work with CA-EBS during helicopter travel. Its training includes helicopter emergency escape: do not automatically buy a separate HUET course as well.

FOET is the follow-on refresher route, not an interchangeable first course. Check the exact product, entry conditions and certificate accepted by the employer and OPITO-approved centre. Safety training is separate from your welding competence and does not promise a job.

Check the medical and offshore-wind requirements separately

Ask which medical certificate the employer accepts, then use the OEUK doctors information to check the examining doctor where relevant. Fitness for a training exercise and fitness for the intended job are separate checks. Let the approved centre and medical examiner decide what evidence you need before booking practical training.

For wind work, GWO’s Basic Safety Training standard covers areas including working at height, first aid and sea survival. Do not assume an oil-and-gas training package automatically meets a wind employer’s requirements, or that every wind job involves welding. Match the training to the named role and site.

Compare offshore pay without inventing a yearly salary

Compare the terms of a real offer rather than relying on a headline salary. This guide does not have a verified current offshore-only pay sample. The welder salary guide provides general career-pay context, not offshore or diving pay evidence.

For a real offer, ask about the hourly or daily rate, guaranteed paid days, shift length, rotation, travel days, accommodation, expenses and who funds training renewals. Establish whether time between trips is paid. Multiplying a short contract’s day rate by a full working year can overstate the income available.

Put the terms in writing before comparing offers. A high advertised rate cannot tell you how often you will be working, and a safety certificate does not guarantee that rate.

Your next useful step

If you are starting out, use the welding career-change guide to compare practical entry routes. If you already have relevant experience, search welding vacancies and check each advert for the setting and qualifications. These are wider welding results, not a promise of current offshore openings.

Use the welder CV builder to record genuine processes, materials, projects and current certificates. You can use it without an account. Before buying another course, send the recruiter a concise list of what you already hold and ask what the vacancy still requires.

Step-by-Step Career Path

Compare the process, material, position and test requirements in real adverts with your experience.

3

Check before booking

Ask the employer and training centre for the exact safety course, medical and entry requirements.

4

Compare the contract

Get paid days, travel, rotation and costs in writing before comparing income.

Qualifications Needed

  • ✓Relevant welding training and practical evidence
  • ✓Welder qualification appropriate to the specified job
  • ✓Employer-accepted safety training and medical evidence where required
  • ✓Separate approved diving qualifications for commercial diving work

Pros & Cons

Pros

  • Relevant onshore welding experience can form a practical starting point.
  • A written job specification helps you choose training that has a purpose.

Cons

  • Buying safety certificates alone does not secure employment.
  • Travel, time away and unpaid gaps can change the value of a contract.

Frequently Asked Questions

How much do offshore welders earn?▼

This guide has no verified current offshore-only salary sample. Compare the actual rate with guaranteed paid days, rotation, travel and costs. General welder salary guidance is not evidence of offshore or underwater-welding earnings.

Do I need to learn underwater welding?▼

Not for a topside welding job above water. Underwater work is a separate commercial-diving route; check HSE guidance and the requirements for the specific job and jurisdiction.

Should I book BOSIET and HUET separately?▼

Do not assume you need both as separate purchases. OPITO’s BOSIET with CA-EBS includes helicopter emergency training. Confirm the exact course and certificates required with the employer and approved training centre.

Will safety certificates get me an offshore welding job?▼

They do not guarantee employment or replace welding competence. Check a real vacancy’s process, material, qualification and experience requirements before paying for training.

Are oil and gas and offshore wind requirements the same?▼

Do not treat them as interchangeable. GWO publishes training standards for wind, while the OPITO product described here is for oil and gas. The employer must confirm the courses and medical evidence accepted for the specific role.
