Our Ventilation & Air Balancing online course is perfect for anyone working on ventilation systems in the marine or offshore industry.

With six modules to work through using a combination of reading materials and videos, we teach you how to test for air leakage, how to diagnose pressure issues and much, much more.

This course is just £350.00 for full access and includes our Tradewinds Certificate of Completion on successfully passing the final exam. The exam is made up of multiple choice questions and relates to everything covered in the study material.

Our online remote-learning courses are a fantastic option for those who wish to learn at their own pace.
