Severe weather leaves technicians stranded on turbine for 18 hours

What happened?

At approximately 06:00, technician teams were conducting a pre-sail briefing with weather forecasts indicating normal conditions.

By 15:00, weather conditions had deteriorated, prompting a decision to begin transferring technicians back to the mainland from the wind farm.

During the return transfers, sea conditions worsened, making further safe transfers impossible.

The last team of four technicians was left on a wind turbine due to safety concerns during transfer.

The team remained on the turbine for 18 hours without access to overnight provisions or basic amenities.

No injuries occurred, but the situation presented a significant welfare and planning risk.

Why did it happen?

Technicians did not verify the presence of overnight provisions on their vessels before departure.

Instructions regarding stranded kits were ambiguous, leading to inconsistent interpretation and application.

The contingency plan did not consider the difficulty of hoisting provisions in deteriorating weather conditions.

Offshore coordination and the vessel master failed to communicate timely weather updates as conditions changed.

The original weather forecast underestimated the speed and severity of the worsening conditions.

What did they learn?

Overnight provisions must be included in vessel checklists and regularly verified for readiness.

Standard operating procedure wording must be revised to remove ambiguity and ensure clarity.

A management of change process should be implemented when deciding where provisions are stored.

Weather communication protocols between offshore coordination and vessels must be improved.

The decision to leave the team on the turbine was correct for safety but highlighted critical gaps in emergency preparedness.

Ask yourself or your crew

Should there be a standardised checklist to ensure overnight provisions and other emergency items are always available on vessels?

How confident are we in our current process for managing changing offshore weather conditions?

What steps can we take to ensure clearer communication between offshore coordination and vessel crews?

How do we verify that contingency plans are practical and executable under real weather scenarios?

Could a similar situation happen here, and would we be prepared?
