Comparison on Offshore Wind Construction Vessel Workability Based on Two Inverted Distance Weighting Interpolating Schemes
Two schemes of inverted distance weighting(IDW)method are proposed towards the interpolation of the construction vessel workability.In the comparison,the global forecast wave data,of which the spatial resolution is(1/12)° provided by France Meteo,is employed.The offshore wind mono pile foundation constructed by a crane vessel with 180 m length is studied,and 144 interpolating points averagely spaced in one of the planned China's wind farm is selected.The results show that,the construction vessel workability computed with two schemes is extremely similar to each other.The errors between both for any interpolating point is below 1.5％,which can be considered as equivalent in accuracy in engineering application perspective.It can be interchangeable in different application scenarios.
