Offshore wind power construction maintenance window region selecting method based on wind wave prediction

Abstract

The invention relates to the field of offshore construction, in particular to an offshore wind power construction maintenance window region selecting method based on wind wave prediction. The offshore wind power construction maintenance window region selecting method based on the wind wave prediction comprises the steps of firstly, making offshore wind power construction maintenance operation to be modular process operation; secondly, selecting and calculating sensitive meteorological factors and sensitive ocean factors of the offshore wind power construction maintenance operation, then utilizing the relation between all offshore wind power construction maintenance operations and the sensitive meteorological factors and sensitive ocean factors corresponding to the offshore wind power construction maintenance operations to establish a decision tree model; finally, utilizing the decision tree model and a probabilistic method to select a suitable offshore wind power construction maintenance window region. The offshore wind power construction maintenance window region selecting method based on the wind wave prediction can systematically and scientifically select an operation window region, optimize offshore operation construction and operation process, ensure construction safety, improve efficiency, optimize resource configuration and greatly reduce the construction cost.

Description

technical field [0001] The invention relates to the field of offshore construction, in particular to a method for selecting a maintenance window for offshore wind power construction based on wind wave prediction. Background technique [0002] Construction and maintenance window area: The window area here refers to the continuous time period, and the construction maintenance window area refers to the continuous time period for construction and maintenance operations. [0003] Wind and wave forecast: Here, wind and wave refer to a general term, not simply referring to sea wind and waves, but also including the prediction of a series of sensitive weather and ocean elements related to offshore construction, such as wave propagation cycle, precipitation, temperature, etc. [0004] With the announcement of the offshore wind power feed-in tariff this year and the introduction of a number of new energy favorable policies, domestic offshore wind power installed capacity will usher in...
