I always got a thrill from working high and always availed myself of such opportunities. I take it you share that sensibility. Congratulations. As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
None of the technology is transferable to offshore, at least as it's practiced in Europe. Everything there is specialized for a particular technology configuration only applicable to the "pool table" of the North Sea. As an example, Germany's largest shipper, Beluga Shipping, in a joint venture with the largest construction company Hoch-Tief, yesterday announced the orders for two new transport and erection ships, with a further two if all goes as planned. (Here in Bremen!)
PS. I can now officially announce that Deutsche WindGuard is technical manager of Germany's first offshore project, Alpha Ventus. It is an exciting time to have moved to Bremen. "Life shrinks or expands in proportion to one's courage." - Anaïs Nin
Offshore, the turbines used are too big to be transported onland - so the factories are by the sea or by rivers and the equipment is transported directly by ship or barge to the sites. In the long run, we're all dead. John Maynard Keynes
