  • Since global energy consumption and demand for energy have dramatically risen, a focus on environmental problems and sustainability has become more important. Clean and renewable energy sources such as offshore wind power generation have received attention among new renewable energy options as alternative energy resources. Due to maintenance and operational perspectives, offshore wind farms have been planned for installation in many coastal waters. However, development of offshore wind farms faces interference from existing maritime traffic along the planned areas. In order to safely and effectively govern marine traffic in the vicinity of wind farms and inner areas, standard criteria are suggested to allow vessels to sail the internal waters of offshore wind farm areas. Therefore, the purpose of this study is to establish allowable criteria for sailing vessels and safety zones for offshore wind farms by investigating the local regulations of various offshore wind farm cases overseas. The commended inner safety zone of wind farms is proposed to be a distance of 150 % of the rotation diameter of the wind turbine rotor and a distance of 200 m from the outer wind turbine for the outer safety zone. Besides this, the allowable criteria for sailing vessels within a wind farm is proposed to have an air draft of 14.47 m south-west wind farm sea areas for a minimum margin to avoid hull contact through evaluation of the tide and height of a wind turbine. further studies will be needed to establish vessel sailing criteria among adjacent offshore wind farms as well as vessel sailing criteria within a single offshore wind farm.

  • As a way to address global warming, among the renewable energy sources, there have been heavy investments worldwide for the development of offshore wind farms. However, such development has a drawback: investment costs are higher than those for onshore wind farms due to required operations such as offshore transportation and installation. In particular, delays in installation due to adverse maritime weather conditions are factors that affect the economics of offshore wind farms' operation. Therefore, in this study, we analyze the optimal schedule of the construction of an offshore wind farm from a macro perspective by considering the weather conditions in Korea. For this purpose, we develop a mathematical model and apply it to a 2.5 GW offshore wind farm project on the southwestern coast of the country. We use data from the Korea Meteorological Agency for maritime weather conditions and attempt to reflect the actual input data based on precedent cases overseas. The results show that it takes 6 months to install 35 offshore wind turbines. More specifically, it is pointed out that it is possible to minimize costs by not working in winter.

  • 주요 통항로에 설치된 해상교량과 해상풍력단지는 선박의 안전항해에 지대한 영향을 미친다. 특히, 90년대 들어 국내에 다수 건설된 해상교량은 과거에 경험하지 못한 대규모 선박-교량 충돌사고의 유발 가능성을 예고하고 있다. 또한 국내 군산지역에 구축될 해상풍력단지 역시 선박과의 충돌 가능성을 내포하고 있다. 이 논문에서는 과거에 연구 개발된 해상교량과 해상풍력단지의 안전성 평가기법을 조사하고, 향후 실용화 방안을 모색하였다. 연구결과, 기존 연구결과를 토대로 위기관리 시스템을 구축하면 궁극적인 해양사고 예방이 가능할 것으로 고려되었다.

  • Offshore wind power is a representative renewable energy source and a rapidly growing industry. In Gyeongsangnam-do, offshore wind farms of 461.9MW are being pushed for in the Yokji island and are expected to expand further to over 1GW in the future. Accordingly, ports supporting the storage, assembly, transportation, and installation of offshore wind power equipment are expected to play an important role in the smooth progress of the offshore wind farm development project. Based on previous research and cases in major countries,this study prepared criteria for assessment of ports supporting offshore wind farmsand evaluated ports in Gyeongsangnam-do, which are linked to Yokji island offshore wind farms. The assessment criteria have been subdivided into distance from the offshore wind farm, port entry and exit restrictions, navigational areas, fishery rights factors, additional costs, berth length, depth of berth, size of the port yard, port berth bearing pressure, interference with other cargo, a civil appeal, and relevant industrial aggregation. The ports of Tongyeong, Samcheonpo, Kohyun, Masan, and Jinhae in Gyeongsangnam-do were selected and evaluated. As a result, the port of Tongyoung was superior in terms of distance from the Yokji island offshore wind farm. The ports of Samcheonpo, Masan, and Jinhae were evaluated as excellent in other criteria such as berth length, depth of berth, and so on. This study is expected to be used as a source of basic data for offshore wind power companies and policymakers to select and evaluate the supporting ports of offshore wind farms.

  • 국내 해역의 해상풍력 개발 가능량을 평가하기 위하여 풍황, 수심 등을 고려하여 개발 가능량을 추정하였다. 풍력등급 3 이상, 수심 50 m 이내의 영역에 대하여 사회.환경적 영향을 고려하기 위한 제약조건을 반영하여 개발 가능량을 산출하였으며, 현재의 기술수준으로 개발 가능하다고 판단되는 수심 30 m 이내의 영역에 대한 개발 가능용량이 약 11 GW 정도로 추정됨에 따라 풍력발전 용량을 2030년까지 7.3 GW 이상 확보하고자 하는 국가 신재생에너지 보급목표의 달성 가능성이 기대된다. 본 연구결과는 해상풍력 개발단지 선정을 위한 기초 자료로 활용되며, 입지 선정 후 기상관측, 환경영향조사 등의 세분화된 단지조사를 통한 해상풍력 실증단지 설계 및 경제성 평가 등이 계속 진행될 예정이다.

  • In recent years, many researchers and developers have been interested in renewable energy all over the world. Particularly, the development of wind power is being processed actively due to its high economic efficiency. A few years ago, Korean government has started the research for building a large-scale offshore wind farm in domestic west-southern area. Current domestic SCADA technology level for operating wind farm is very low compared with foreign SCADA technology level. In this paper, we found IT issues and solutions for developing SCADA system. Based on these solutions, we designed SCADA system for a large-scale offshore wind farm.

  • 본 논문은 해양공간계획법에 근거한 해양에서의 다양한 용도 경합이 예상되는 울산 부유식 해상풍력발전단지 조성사업에 대하여 살펴보고자 한다. 해양공간계획법에 따르면 다양한 용도가 중첩되는 경우, 자연환경, 사회경제적 여건 및 주변 해역의 이용 및 보전 현황 등을 고려하여 관리의 우선순위를 정해야 한다. 이에, 해상풍력발전단지 설립에 따른 해양환경 및 천연자원 영향성 평가의 경제적 피해액을 추정한다. 이는 해양공간계획 시, 용도지정 우선순위를 정할 때 객관적 자료가 될 수 있고, 나아가 효율적인 풍력발전단지 운영을 위한 기초 자료가 될 것이다.

  • This paper aims to presents a systematic procedure for the development of construction technology roadmap, which can consider the offshore wind farm on port. Then the weight among the large/medium/small classified construction technology has identified through the AHP(Analytical Hierarchy Process) approach using FGI(Focus Group Interview) and questionnaire study. Based on the priority for classified construction technology a construction technology roadmap for port offshore wind farm was also developed. The technology roadmap suggests the time frame(20 years, from 2016 to 2036) to complete R&D work for the classified construction technology of port offshore wind farm. Such construction technology roadmap can be utilized as a milestone in setting up the R&D strategy in the green port construction industry.
