A design wave may be accompanied by a requirement for the use of a particular periodicwave theory用于海上结构物的设计，具有指定高度、周期和方向的确定性波浪。设计波浪可能要求采用特定的波浪周期理论3.4 designer设计方party or parties responsible for the design of an offshore wind turbine负责海上风力发电机组设计的一方或多方3.5 environmental conditions 环境条件characteristics of the environment (wind, waves, sea currents, water level, sea ice, marine growth,scour and overall seabed movement, etc.) which may affect the wind turbine behaviour可能影响风力发电机组性能的环境特性（如风、浪、洋流、水位、海冰、海生物、冲刷和整体海床运动等;3.6 external conditions (wind turbines)外部条件（风力发电机组）factors affecting operation of an offshore wind turbine, including the environmental conditions, theelectrical network conditions, and other climatic factors (temperature, snow, ice, etc.)影响海上风力发电机组运行的因素，包括环境条件、电网条件和其他气候因素（如温度、降雪、结冰等等）3.7 extreme significant wave height 极端有效波高expected value of the highest significant wave height, averaged over 3 hours, with an annual probability3.8 extreme wave height极端波高expected value of the highest individual wave height (generally the zero up-crossing wave height) withan annual probability of exceedance of 1/N (“ recurrence period” : N years)最高单个波高的期望值（通常为向上跨越零点的波高），超过这个期望值的年概率为1/N（“ 重复周期” ：N年）;3.9 fast ice cover固定冰盖a rigid continuous cover of ice not in motion静止状态下的连续刚性冰覆盖层3.10 fetch风距distance over which the wind blows constantly over the sea with approximately constant wind speedand direction风以近似恒定的风速和风向持续地吹过海面所经过的距离3.11 foundation基础part of an offshore wind turbine support structure which transfers the loads acting on the structure intothe seab
