摘要
為了落實我國離岸風力發電產業本土化,國內許多的廠商也開始投入了大量的資金,引進了許多新技術與設備。而在離岸風場開發時,不論是場址的選定、風機設置位址的規劃,或是風機基礎型式的選擇與設計,都必須仰賴足夠的場址調查資料作為規劃設計之依據。
離岸風場工址調查可獲得之資訊包含:海氣象、洋流變化、漂砂情形、海床地形與地貌、海床下地層剖面、海床下埋設物分布情形、海床下地層地質構造與特性等。在執行調查時,通常會把調查工作分成四個部分:海氣象與水文調查、地球物理探測、地質鑽探取樣與試驗調查、水下攝影調查。
本文之目的,係針對離岸風場工址調查時所需進行之所有調查工作,進行完整之介紹與說明,並探討所採用之各種載台、儀器設備與試驗方法之適用性。提供從事離岸工程規劃設計之工程人員,於離岸工址調查之安排與方法選擇上,能有所參考之依據。
英文摘要
In order to realize the localization of domestic offshore wind power industry in Taiwan, a lot of local construction companies and vendors have begun making a large amount of investments in introducing new technology and equipment. When an offshore windfarm is developed, extensive and detailed site investigation is required to provide the reference information for determining the windfarm siting, the arrangement and distribution of wind turbines, the types and design methodology of the turbine foundation.
The information gained from offshore windfarm site investigation includes sea states, current changes, littoral drift conditions, seabed topography and formation, sub-bottom profile, distribution of buried objects, and geological substructure and characteristics under the seabed. The investigation is often divided into four parts: sea state and hydrological survey, geophysical survey, geotechnical investigation and laboratory testing, and ROV exploration.
The purpose of this paper is to shed light on various investigation works required for offshore windfarm site
investigation, and to explore the suitability of different kinds of adopted working platforms, devices and equipment, and
laboratory test methodology. This paper can serve as a reference for offshore engineering planning, as well as the
organization and methods suitable for offshore site investigation.
