What is an offshore medical?
Before heading offshore, there is one requirement that sits alongside your safety training: the offshore medical. Whether you are new to the industry or renewing your certificates, understanding what an offshore medical involves, who needs one, and how to get it will help you stay compliant and ready for your next project. Here is everything you need to know.
What is an offshore medical examination?
An offshore medical examination is a fitness assessment carried out by a certified physician to confirm that a worker is physically and mentally fit to work in an offshore environment. It evaluates whether a person can safely perform their duties and respond to emergencies in remote, high-risk locations where immediate medical care is not available.
Offshore environments, including oil and gas platforms, wind farms at sea, and marine vessels, present unique physical and psychological demands. Workers may face extreme weather, confined spaces, heavy lifting, shift work, and emergency situations that require a fast physical response. The offshore medical exists to ensure that every person on site is capable of meeting those demands without putting themselves or their colleagues at risk.
The examination is not a general health check. It follows specific standards set by industry bodies and must be conducted by a physician who is approved to carry out offshore fitness assessments.
Who needs an offshore medical certificate?
Anyone working offshore is required to hold a valid offshore medical certificate. This includes workers in the oil and gas sector, offshore wind technicians, maritime crew, and contractors or subcontractors who spend time on offshore installations or vessels.
The requirement applies regardless of your specific role. Whether you are a drilling engineer, a catering worker, a maintenance technician, or a safety officer, the same fitness standard applies. Employers and operators are legally responsible for ensuring that every person on their site holds a current certificate before they board.
For professionals who work across multiple sectors or regions, it is worth noting that different standards may apply depending on where you work and who the operator is. Understanding which standard applies to your role is an important first step.
What does an offshore medical examination include?
An offshore medical examination covers a range of physical and psychological health checks designed to assess overall fitness for offshore work. The specific tests may vary slightly depending on the standard being applied, but most examinations include the following:
- General physical examination, including height, weight, and BMI
- Blood pressure and cardiovascular assessment
- Vision and hearing tests
- Urine analysis
- Lung function test (spirometry)
- Musculoskeletal assessment
- Review of medical history and current medications
- Mental health and psychological fitness evaluation
- Electrocardiogram (ECG) for older workers or those with cardiac risk factors
The physician will assess whether any existing health conditions, medications, or physical limitations could pose a risk in an offshore setting. If a concern is identified, the worker may be referred for further investigation before a certificate is issued.
How long is an offshore medical certificate valid?
An offshore medical certificate is typically valid for two years for most workers. However, workers over the age of 40 may be required to renew their certificate annually, depending on the applicable standard and the physician’s assessment of their health status.
It is important to track your certificate’s expiry date carefully. An expired offshore medical means you are not permitted to travel offshore, which can lead to project delays and last-minute complications for both you and your employer. Renewing in good time, ideally several weeks before the expiry date, avoids unnecessary disruption.
Some operators may also require a new medical if there has been a significant change in your health since your last examination, such as a serious illness, surgery, or a new long-term condition.
What is the difference between OGUK and NOGEPA medicals?
The key difference between OGUK and NOGEPA medicals lies in the regional standard they apply to. OGUK (Offshore Energies UK, formerly UKOOA) is the standard used in the UK North Sea, while NOGEPA is the standard applied in the Dutch sector of the North Sea.
Both standards assess offshore fitness and cover similar areas of health evaluation, but they are administered by different approved physicians and recognised by different operators and regulatory bodies. A worker holding an OGUK medical may not automatically meet the requirements for a Dutch offshore project, and vice versa.
Here is a quick comparison of the two standards:
- OGUK Medical: Required for UK North Sea operations. Issued by OGUK-approved physicians. Widely recognised by UK operators and contractors working in British waters.
- NOGEPA Medical: Required for Dutch North Sea operations. Issued by NOGEPA-approved physicians. Recognised by operators working under Dutch regulatory frameworks.
- Mutual recognition: Some operators accept both standards depending on the project and contract terms. Always confirm with your employer or operator which standard applies before booking.
If you work across both regions, you may need to hold both certificates. Checking your contract requirements in advance will save time and avoid any compliance issues on the day of departure. You can explore NOGEPA training and certification courses to ensure you meet Dutch sector requirements.
Where can you get an offshore medical certificate?
An offshore medical certificate must be obtained from a physician who is approved to conduct offshore fitness examinations under the relevant standard, either OGUK, NOGEPA, or another applicable framework. General practitioners cannot issue offshore medicals unless they hold the specific approval required.
Approved physicians can be found through the relevant industry body’s register. Many offshore training centers and occupational health clinics that serve the energy sector can also direct you to approved practitioners in your area. For professionals based in or travelling through the Netherlands, there are several approved NOGEPA medical providers operating near major industry hubs and ports.
When booking your offshore medical, it is a good idea to bring your current certificate (if renewing), a list of any medications you take, and details of any recent medical procedures or conditions. This helps the physician complete the assessment efficiently and avoids unnecessary delays in issuing your certificate.
Pairing your offshore medical with your safety training requirements, such as OPITO HUET, FOET, or BOSIET courses, ensures you are fully compliant before your next offshore mobilisation.

Frequently Asked Questions
Can I fail an offshore medical examination, and what happens if I do?
Yes, it is possible to be assessed as temporarily or permanently unfit following an offshore medical. If a concern is identified, the physician may issue a conditional certificate, refer you for further specialist investigation, or determine that you are not fit for offshore work at that time. A temporary unfit outcome does not necessarily end your offshore career — many workers successfully address the underlying issue and pass a follow-up examination. It is worth discussing the outcome openly with the physician and your employer to understand your options and any recommended next steps.
Do I need to disclose all medications and medical conditions during the examination?
Yes, full disclosure is essential and strongly advised. Withholding information about medications, diagnosed conditions, or recent procedures is not only a compliance risk — it can also be a serious safety risk to yourself and your colleagues offshore. The physician's role is not to disqualify you but to assess whether your condition is manageable in an offshore environment. Many workers with ongoing health conditions hold valid offshore medical certificates, provided their condition is well-controlled and does not impair their ability to respond to emergencies.
How far in advance should I book my offshore medical before a project starts?
Ideally, you should book your offshore medical at least four to six weeks before your planned mobilisation date. This allows enough time to complete the examination, address any follow-up investigations if required, and receive your certificate without last-minute pressure. If you are also booking safety training courses such as BOSIET or FOET, coordinating both well in advance ensures everything aligns before your departure date. Leaving it too close to your start date is one of the most common causes of avoidable mobilisation delays.
What happens to my offshore medical certificate if I have a significant illness or surgery between renewals?
If you experience a serious health event — such as a heart condition, major surgery, or a newly diagnosed long-term illness — between your renewal dates, you are typically required to inform your employer and may need to undergo a new offshore medical assessment before returning to work offshore. Most operators and regulatory standards include this requirement to ensure that any significant change in your health status is properly evaluated. Do not assume your existing certificate remains valid after a major health event; always check with an approved physician and your employer before mobilising.
Is an offshore medical the same as a seafarer medical (ENG1 or ML5)?
No, these are different certificates designed for different purposes and regulatory frameworks. An ENG1 or ML5 is a seafarer medical certificate required under maritime regulations for those working aboard ships, issued under MCA (Maritime and Coastguard Agency) standards. An offshore medical such as OGUK or NOGEPA is specifically designed for workers on offshore installations, platforms, and wind farms. While there is some overlap in the health areas assessed, the two certificates are not interchangeable. If your role involves both maritime and offshore work, you may need to hold both.
Can I get my offshore medical and safety training done at the same location?
In many cases, yes. Several occupational health providers and offshore training centres operate near the same industry hubs, ports, and airports, making it practical to schedule both on consecutive days or within the same trip. While FMTC Safety focuses on OPITO-certified safety training, our team can point you in the right direction for approved medical providers near our training centres in the Netherlands and other locations. Coordinating both in one visit reduces travel time and helps you arrive fully compliant for your next offshore project.
What is the best way to prepare for an offshore medical examination?
The most practical steps you can take before your appointment are to gather a complete list of your current medications (including dosages), bring documentation of any recent surgeries, diagnoses, or specialist consultations, and ensure you have your previous offshore medical certificate if you are renewing. On the day itself, avoid heavy meals, alcohol, or strenuous exercise beforehand, as these can affect blood pressure and urine test results. Being well-rested and well-hydrated also helps ensure accurate readings across the various assessments. Arriving prepared means the physician can complete your examination efficiently with minimal risk of delays.
