Zeschky took the decision to cancel the N150 turbine months after joining the company in late-2011. At the 2012 EWEA conference, he warned Nordex would scrap the project if it failed to bring in a development partner.
At the time, a large number of offshore turbines were in development.
Speaking last week at WindEnergy Hamburg, Zeschky said: "If I think back it was a tough decision. It faced a lot of questions and doubt within the company and many people we talked to.
"I still think it was right, and economics have proved it was the right decision. For a mid-sized company like us, offshore projects are too big. That's for the large corporations."
Asked whether there was a case for pure-player wind manufacturers to remain in the offshore sector, Zeschky said the most important factor was company size.
"If the turbines in a single offshore project have a value of EUR 500 million or more you need guarrantees and take risks in execution, and you need a certain size balance sheet to do that."
At the time Nordex pulled away from offshore, it focused strategically on low wind areas. The company's N117 turbine recently won “uåX˜äŠÊ˜·³Ç's product of the year, while the company also launched a 64.4 metre onshore blade at the Hamburg event.
