Shoulder Width Measurement for Offshore Workers: What You Need to Know
Shoulder width measurement is a required safety assessment for many offshore workers, particularly those traveling by helicopter to offshore installations. While it may appear straightforward, this measurement plays an important role in helicopter seating, evacuation safety, and HUET compliance.
This guide explains what shoulder width measurement is, why it matters offshore, and when re-measurement may be required.
What Is Shoulder Width Measurement?
Shoulder width (also called shoulder breadth) is measured as the horizontal distance across the widest part of the shoulders, typically from the outer edge of one shoulder to the other.
In offshore environments, this measurement is used to assess:
Suitability for helicopter seating
Ability to exit aircraft safely during an emergency
Compliance with offshore aviation safety guidelines
Why Shoulder Width Matters for Offshore and HUET
Offshore helicopters operate within strict cabin and exit-space limitations. During emergency scenarios — including ditching or underwater evacuation — passengers must be able to move quickly through exits without restriction.
If an individual’s shoulder width exceeds certain limits, it may affect:
Assigned seating location
Exit accessibility
Evacuation timing during emergencies
These assessments are designed to reduce evacuation risk and improve overall helicopter safety.
Shoulder Width Thresholds in Offshore Aviation
Industry guidance commonly references 55.9 cm (22 inches) as the threshold at which an individual may be considered extra-broad.
Below 55.9 cm → Standard helicopter seating applies
At or above 55.9 cm → May require seating restrictions or additional review
Workers who measure near this threshold are often flagged for follow-up measurement to ensure ongoing safety and accuracy.
How Often Should Shoulder Width Be Re-Measured?
A frequent question from offshore workers and employers is how often re-measurement is required.
Key points:
There is no universally fixed re-measurement interval solely based on proximity to the threshold
Re-measurement is typically recommended:
During offshore medical or certification renewals
If there has been significant physical change
When required by employer or operator policy
Shoulder Width Measurement at Beeline Clinical
At Beeline Clinical, shoulder width measurement is a service we often offer to individual in the offshore wind, and oil & gas industries.
Our process focuses on:
Consistent measurement technique
Clear explanation of results
Alignment with offshore safety expectations
Transparent guidance if re-measurement is recommended
We aim to ensure workers understand what the measurement means and why it matters, without confusion or ambiguity.
Frequently Asked Questions (FAQ)
Is shoulder width measurement required for HUET?
Yes. Shoulder width measurement is commonly required for offshore workers who must complete HUET or helicopter travel as part of their role.
Does being close to the threshold mean I’m unfit for offshore work?
No. Measuring close to the threshold does not automatically disqualify an individual. It may simply indicate the need for monitoring or re-measurement.
Can shoulder width change over time?
Yes. Body composition, posture, and muscle mass can change, which is why re-measurement may be appropriate at certain intervals.
Summary
Shoulder width measurement is a critical but often misunderstood part of offshore safety. When performed correctly and reassessed when appropriate, it helps ensure:
Safe helicopter evacuation
Proper seating assignments
Compliance with offshore aviation standards
For offshore workers, it’s not about passing or failing — it’s about safety, preparedness, and risk reduction.
