一、引言近海设施由于海生物的生长发生了污损,其程度和类型基本上取决于地理位置。总的来说,平台遭受污损最严重的区域位于海面和水下约30米之间。海生物的附着大大地增加了结构的重量、表面粗糙度以及桩腿和组件的直径。这本身又使经受着最大波浪载荷的结构组件 I. INTRODUCTION Offshore installations have been defaced by the growth of marine life, and their extent and type basically depend on their geographical location. In general, the most defaced areas of the platform are located about 30 meters above sea level and underwater. The attachment of sea creatures greatly increases the weight of the structure, the surface roughness, and the diameter of the legs and components. This in turn allows the structural components to withstand the largest wave loads
