The industry experts are those who have taken charge of lots of wind projects or have made deep and wide research on offshore wind farm construction, like senior management or engineers of investment corporation, design and research institute, wind turbine manufacturer and construction enterprises.
For professional experts, they are almost the engineers, researchers or technicians respectively employing in design, research and construction institute related to offshore wind projects.
These groups of experts may not be very familiar with whole wind farm projects, but they have make deep research on their own specialty, like hydrology, geology, civil engineering, oceaneering and electrical engineering, etc.
For example, to the influence factor wave feature and wind resource, industry experts know which is more important for offshore wind farm construction, while they may not know the exact grade of wave or wind in this sea area or maybe will give high score of the weighting coefficient and its value both for wind resource if the expert is major in wind engineering.
