FEATURE NORTHERN OFFSHORE SERVICES "The offshore wind industry is relatively young and has grown tremendously during the last 15 years. Since we began N-O-S in 2008, we have seen wind turbines become significantly larger, which results in more maintenance, increased downtime and more technicians at sea. These are just some of the challenges that are catalyzing innovation and driving the design and manufacture of our vessels in house to meet the customer demands of tomorrow." – David Kristensson,
