해상풍력 구조물 및 해저케이블 설치시공 조사연구 = Survey research of construction and installation work related with submarine structure and submarine cable of Offshore wind power

다국어 초록 (Multilingual Abstract)

This paper looks over the construction of Offshore wind turbine substructures as well as submarine cabling work etc.
Wind power is the most popular energy with the greatest potential among various renewable energy sources, such as photovoltaic, wind, tidal power and marine bio-energy. In particular, Offshore wind power is the type of energy which can be actively used and developed in Korea, a nation surrounded by the sea on three sides. The Korean government took note of such possibilities and has operated test facilities, securing technology and experience. All these efforts were geared towards finding out national new growth engines.
Offshore wind power development in Korea is now at the test operation stage which was firstly implemented at the Jeju Island. However, European nations have actively tapped the energy so far, building and operating Offshore facilities. As a result, detailed analyses were conducted on its various impacts on the marine environment.
Recently the development of Offshore wind farm and a new design Offshore foundation have been performed competitively all over the world.
On the basis of research on substructure regarding Offshore wind power, Jacket or Mono pile type are recommended for application in Korean peninsular in the point of economical investment and availability rather than suction pile and pile cap type. But the pile cap is also suggested as an optimal foundation type for the test bed. In conclusion it is required to examine the site characteristics, external loads, construction cost, environmental impacts and aesthetic aspect etc. finding an optimal solution.
For submarine cable construction, the oceanographic survey will be carried out to find the cable route and protection method. There are special equipment such as plough as well as cable installation vessel required for pulling and burying of the cable installation in submarine.
Also, Korea has the infinite possibilities to improve the technology of the Offshore wind power by virtue of fundamental industry well implemented with Heavy industry and Engineering & Construction Company.
