Hi Jerome, like always interesting and open thoughts. Floating will not be working as the turbines are of no good quality currently. Theoretically designed for a yearly maintenance the reality looks quite different. For every little broken fan or fuse you have to send 3 people to the turbine, too many recurring inspections for lifts, eye-bolts, ladders etc, serial damages of bearings, generators and gearboxes etc. etc. . And for floating turbines, which you can not reach as in rougher waters and not place a jack-up the O&M model will crash.
Hi Rüdiger - the cost of O&M is indeed on the items that are still unknown for floating - and the high rate of "teething problems" on the last generation of turbines is certainly not helping. I do hope and expect that this is a temporary problem - the turbine manufacturers were pushed hard (by the oil&gas players and others trying to bet on merchant pricing) to move too quickly to larger turbine models and did not do good enough work on the latest generation - lack of time and money, but they are now pushing back against that, and working to solve the problems.
Fixed bottom is also not viable with the current rate of problems, so that needs to be solved in any case. Large component replacements that require a jack up (or transfer to shore in the case of floating turbines) are something that should happen as little as possible in any case - the industry has learnt a lot in the past 20 years, let's hope that the past 3 years are just an unhealthy parenthesis.
I fear you are not right. I experience only fully blockage of manufacturing surveillance, no willingness to talk about the issues, sales people, who have no clue about what is going in reality and complete intransparancy on the manufacturer‘s side. But you are right: All developers (and not only the oil & gas companies) pushed too much for bigger turbines. Greetings from close to Lyon on the highway
Your comment and mine are not necessarily incompatible :) What you describe is "normal" - maybe I had the advantage that on debt-funded projects banks require a lot of transparency and some better practices evolved. But on utility-driven projects there is much less transparency (and yet they think they know the market much better...)
