Description

해상풍력발전기 설치전용선 잭업하우스{Jack-up house for wind turbine installation vessel}Jack-up house for wind turbine installation vessel

본 발명은 해상풍력발전기 설치전용선 잭업하우스에 관한 것으로, 더욱 상세하게는 레그의 승강공간 외측에 링을 형성하여 안전하게 잭에 유압을 공급할 수 있도록 된 해상풍력발전기 설치전용선 잭업하우스를 제공한다.
The present invention relates to an offshore wind turbine installation dedicated line jack up house, and more particularly provides a offshore wind turbine installation dedicated line jack up house to form a ring outside the lifting space of the leg to safely supply hydraulic pressure to the jack.

지구는 대기가 존재하지 않는다면 태양으로부터 받은 빛에너지를 그대로 방출하므로 표면의 평균온도가 -20℃가 된다. 하지만 지구는 대기가 존재하기 때문에 태양으로부터 받는 긴 파장의 빛이 외부로 방출되지 못하고 대기 중에 흡수되어 기체분자의 운동량을 증가시키므로 표면의 평균온도는 15℃로 올라간다.Earth emits light energy from the sun as it is without the atmosphere, so the average surface temperature is -20 ° C. However, since the Earth is in the atmosphere, the long-wavelength light from the sun is not emitted to the outside and is absorbed in the atmosphere, increasing the momentum of gas molecules.

하지만 최근에 들어 산업이 발전함에 따라 석유나 석탄 같은 화석연료의 사용량이 증가하고 농지를 확보하기 위해 숲을 파괴하면서 온실가스의 원인이 되는 이산화탄소의 양이 급격히 증가하여 지구 온난화가 가속되고 있다.However, as the industry develops in recent years, global warming is accelerating due to the increase in the use of fossil fuels such as oil and coal and the destruction of forests to secure farmland.

이에 따라 국제사회는 지구 온난화로 인한 기상이변 등의 재앙을 막기 위해 다양한 국제협약을 통하여 각국에서 배출하는 온실가스의 양을 줄이도록 규제하고 있다.Accordingly, the international community regulates the reduction of greenhouse gas emissions from various countries through various international agreements to prevent disasters such as extreme weather caused by global warming.

이러한 온실가스의 양을 줄이기 위해 화석연료를 대신하는 대체에너지에 대한 연구가 활발히 진행되고 있다.In order to reduce the amount of greenhouse gases, researches on alternative energy instead of fossil fuels are being actively conducted.

상기 대체에너지로 자연환경을 이용한 태양열발전, 조력발전, 지열발전, 풍력발전 등이 실시되고 있다.As the alternative energy, solar power generation, tidal power generation, geothermal power generation, wind power generation, etc. using the natural environment are performed.

특히 풍력발전은 무공해 에너지원으로 현재의 대체에너지 중 유지보수비용이 가장 저렴하여 경제성이 매우 높다. In particular, wind power generation is a pollution-free energy source, and the economical efficiency is very high because the maintenance cost is the lowest among the current alternative energy.

또한, 풍력발전장치는 구조나 설치가 간단하고 운영 및 관리가 용이하며 무인화 및 자동화 운전이 가능하다.In addition, the wind power generator is simple in structure and installation, easy to operate and manage, and can be unmanned and automated.

이러한 장점으로 인하여 전세계적으로 2002년말 기준으로 32,154MW 용량의 풍력발전장치가 가동되고 있다.Due to these advantages, wind power plants with 32,154 MW capacity are operating worldwide as of the end of 2002.

상기 풍력발전장치를 설치하기 적합한 장소는 풍력발전이 바람의 힘을 이용하기 때문에 풍속이 빠르고 시간과 계절에 따라 그 방향이 일정한 곳이 바람직하다.The suitable place for installing the wind power generator is preferably a place where the wind speed is fast and the direction is constant according to time and season because the wind power uses the power of the wind.

따라서 과거에는 풍력발전장치가 주로 육상에 설치되었지만, 육상은 미관이나 장소의 제약이 있을 뿐 만 아니라 해상보다 풍속이 상대적으로 적기 때문에 해상에 대규모의 풍력발전단지가 건설되고 있는 추세이다.Therefore, in the past, the wind turbine was mainly installed on the land, but the land is not only limited in terms of beauty and location, but because the wind speed is relatively smaller than at sea, a large scale wind farm is being built on the sea.

그러나, 블레이드와 같은 중량의 풍력발전구조물을 해상에서 운반하거나 높은 위치에 설치하는 것은 육상과는 다른 특별한 공법들이 필요하게 되었다. However, hauling wind turbines such as blades or installing them at high positions requires special methods different from land.

풍력발전구조물을 운반하고 설치하기 위한 장비로는 크레인이 장착된 바지선이 이용되는 데, 풍력발전구조물의 설치시 바지선은 범용으로 설계된 선박이므로 풍력발전구조물의 중량을 이기지 못하고 전복되는 등의 문제점이 종종 발생하고 있다.A barge equipped with a crane is used as a equipment for transporting and installing the wind power generation structure, and when the wind power generation structure is installed, the barge is a universally designed ship, and therefore, problems such as overturning the wind power generation structure are not overcome. It is happening.

또한 풍력발전구조물의 설치시 선박이 움직이지 않도록 하기 위해서 레그를 해저에 박아 선박과 해저의 지면을 견고하게 고정시켜야 한다.In addition, in order to prevent the ship from moving during the installation of the wind power generation structure, the legs must be anchored to the sea floor and the ground of the ship and the seabed should be firmly fixed.

이러한 레그를 승강시키고 고정된 상태를 유지하기 위해서는 잭업하우스가 필요하다.
