OEUK Medical Exams

An OEUK medical certificate is required for a broad range of personnel who work on or travel to offshore installations governed by UK regulations. This includes:

• Platform and rig workers — drillers, roughnecks, derrickmen, tool pushers, and all drilling crew members
• Divers and ROV operators — saturation divers, surface-supplied divers, and remotely operated vehicle pilots working from offshore vessels or platforms
• Crane operators — offshore crane operators responsible for cargo transfer between supply vessels and platforms
• Production and process operators — technicians monitoring and maintaining production equipment on offshore installations
• Construction and maintenance crews — welders, pipefitters, scaffolders, painters, and rope access technicians deployed offshore
• Catering and hospitality staff — galley crew, stewards, and housekeeping personnel on offshore installations
• Visitors and contractors — engineers, inspectors, project managers, and any personnel traveling to offshore platforms by helicopter

Many Texas-based energy workers rotate to North Sea platforms operated by major international companies. The Gulf Coast is home to regional offices for operators like BP, Shell, TotalEnergies, and Equinor, as well as major drilling contractors and oilfield service companies that deploy personnel internationally. An OEUK medical certificate obtained at any Hybrid Health Systems location is recognized by operators on the UKCS.

The OEUK medical examination is a comprehensive assessment that covers every body system relevant to offshore fitness. The exam includes:

• Comprehensive physical examination — head-to-toe assessment including cardiovascular auscultation, abdominal examination, and skin assessment
• Cardiovascular assessment — resting blood pressure, heart rate, ECG if clinically indicated, and review of cardiac risk factors. Workers with hypertension, history of cardiac events, or significant risk factors may require specialist clearance or exercise stress testing
• Respiratory function testing — spirometry to measure lung capacity and airflow. This is critical for workers exposed to drilling muds, welding fumes, diesel exhaust, or confined space atmospheres
• Audiometry — hearing assessment to ensure workers can hear safety alarms, PA announcements, and verbal commands in noisy offshore environments
• Vision testing — visual acuity (corrected and uncorrected), color vision testing, and assessment of visual fields. Color vision is essential for identifying safety signage and distinguishing pipeline markings
• Urinalysis — screening for diabetes, kidney disease, and other metabolic conditions
• BMI and fitness assessment — body mass index calculation and assessment of overall physical conditioning. Extreme obesity may affect certification due to helicopter seating constraints and emergency evacuation requirements
• Mental health screening — evaluation of psychological fitness for working in isolated, high-pressure environments. History of significant mental health conditions requires specialist documentation
• Dental fitness assessment — evaluation of dental health to identify conditions that could cause acute dental emergencies offshore where dental care is unavailable
• Occupational and medical history review — comprehensive review of current medications, previous offshore medical history, surgical history, and any ongoing medical treatment

Workers deploying to installations on the Norwegian Continental Shelf (NCS) require a medical certificate that meets standards set by the Norwegian Maritime Authority (Sjøfartsdirektoratet). While the clinical content of the Norwegian offshore medical is very similar to the OEUK examination, there are specific differences in documentation requirements, fitness categories, and the regulatory framework governing certification.

Key differences between OEUK and Norwegian medical certificates include the regulatory authority that governs the standard, specific fitness category designations, and certain additional screening requirements that Norwegian operators may impose. Our providers are familiar with both standards and will ensure your examination and documentation meet the requirements of your specific deployment.

If you are unsure whether you need an OEUK certificate, a Norwegian certificate, or both, contact our team with your operator name and deployment location and we will confirm exactly which examination you need.

OEUK medical certificates are typically valid for two years from the date of examination. Workers over the age of 50 may be issued certificates with a one-year validity period, and the examining physician may recommend a shorter validity period for individuals with certain medical conditions that require more frequent monitoring.

To prepare for your OEUK medical exam, please bring:

• A valid government-issued photo ID (passport preferred for international deployments)
• Your current offshore medical certificate if renewing
• A complete list of all medications including dosages
• Corrective lenses and/or hearing aids if you use them
• Any specialist letters or clearance documentation related to pre-existing conditions
• Your employer's name and the operator or installation you will be deployed to

Upon completion, you will receive your medical certificate documenting your fitness category and any restrictions. Most certificates are issued the same day. Walk-in appointments are accepted at all locations, but scheduling ahead ensures the fastest turnaround — contact any of our five Texas clinics to book your OEUK medical exam.
