Helicopter Wind Farm Transfer – Westermost Rough

Transfer from Siemens SWT-6.0-154 Wind Turbine at the DONG Energy Westermost Rough Project. Aviation services provided by Uni-Fly A/S. November 8, 2015

Sea conditions prohibited transfer to and from turbine by vessel so helicopter was used to access turbine for maintenance. Wind speeds during transfer varied between 15 – 20 m/s (33 – 45 mph).

For normal transfer vessels, the trip to the wind farm from the port of Grimsby is 2 hours. Flight time to site by helicopter from Humberside Airport is around 12 minutes.

Training requirements for helicopter transfer include, HUET (Helicopter Underwater Evacuation Training), Tower Rescue Up, and Helicopter Hoist Operator training.
