Energy resources essential to a modern industrial society , the direct promotion of scientific and technological progress and development . But human consumption of energy - fossil energy has become increasingly scarce , sooner or later , almost all day . Under severe pressure on resources and the environment , clean energy - wind started to become the industrial countries in the world are scrambling to develop . Therefore , the construction of offshore wind farms has increasingly become a hot issue of the current field of marine engineering . For offshore wind turbines , infrastructure security is one of the key technologies of its design and construction . First , marine environmental load is a very complex nonlinear problem , the theoretical analysis and the calculation is very difficult . Second , the infrastructure as the main part of the wind turbine , its quality directly determines the security, reliability and stability of the wind turbine . Therefore, the analysis of offshore wind turbine infrastructure security is of great significance . The main purpose of this paper is to discuss the security issues of offshore wind turbine foundation structures . Analysis or the development potential of the wind turbine , the basic structure of the form . A large number of domestic and foreign literature , wave loads as a starting point , using Morison equation , system analysis and derivation of the wave load calculation of the basic structure of the offshore wind turbine . On this basis , combined with powerful ABAQUS user subroutine , finite element method proposed environmental load and the development of corresponding DLOAD subroutines and program interface . Finally, the virtual crack closure and numerical calculation method , analysis infrastructure fracture , and gives a relevant example .
