본 발명은 CoG 제어가 가능한 탑사이드 모듈 및 CoG 제어를 통한 탑사이드 모듈의 리프팅 방법에 관한 것으로서, 더욱 구체적으로는 탑사이드 모듈(topside module)이 디자인 변경 등으로 인해 CoG(Center of Gravity)가 변경됨으로써 정해진 CoG 영역(envelope)을 벗어나는 경우, 리깅 플랫폼(rigging platform)에 마련된 밸러스트 탱크(ballast tank)를 이용하여 CoG 시프팅(shifting)을 용이하게 수행할 있도록 하여, 탑사이드 모듈의 리프팅을 가능하도록 하고, 리프팅 용량의 증대에 기여하도록 하는 CoG 제어가 가능한 탑사이드 모듈 및 CoG 제어를 통한 탑사이드 모듈의 리프팅 방법에 관한 것이다. 본 발명에 따른 CoG 제어가 가능한 탑사이드 모듈은 모듈 본체; 및 상기 모듈 본체의 상부에 리깅(rigging)을 적치하도록 설치되고, 밸러스트 탱크(ballast tank)가 다수로 배열되도록 마련되는 리깅 플랫폼(rigging platform)을 포함한다.
Abstract:
The present invention relates to an ecological environment classification method for restoring the habitat of fishes. The present invention includes a step of inquiring about inhabitation characteristics of a target fish species; a step of inquiring spawning characteristics of the target fish species; and a step of inquiring prey characteristics. The inhabitation characteristics are classified according to an inhabitation water system, main habitat (inhabitation location), the size of a river, inhabitation temperature, the structure of a river bed, activating velocity, an ecotype, an action radius, a growth stage in the migration, a migration period, and a swimming type. The spawning characteristics are classified according to a period, a location, water level, a river bed, a temperament, and an action (each). The prey characteristics are classified according to a fry stage and an adult fish stage. The present invention can accurately and rapidly restore a destroyed ecological environment when the ecological environment of a river or a stream is destroyed by developing a stream (or a river) or a downpour; and simply and accurately check ecological characteristics of fishes inhabiting in rivers and streams across the country.

Abstract:
PURPOSE: An underwater barrier line is provided to prevent an invasion of enemies while not obstructing a navigation pass of ships by controlling bars on the top of a concrete foundation. CONSTITUTION: An underwater barrier line comprises a concrete foundation(88), a fence shaft(8), a cylinder chamber(76), a floating shaft(33), an underwater barrier(1), a floatation preventing stand(3), and a total control system. The concrete foundation includes the fence shaft and the cylinder chamber on the top. The floating shaft is joined to the shaft in the middle part of a fence, and an underwater fence is formed over the floating shaft. A hydraulic cylinder system is arranged in the underwater fence, thereby controlling the height of the underwater fence. An electronic sensor is joined to a floating ball, thereby transmitting the movement of the underwater fence to the total control system.
Abstract:
PURPOSE: A stone net structure for protecting a slope and a construction method using the same are provided to easily construct the structure, and prevent the structure from being lost by such as flood. CONSTITUTION: A stone net structure for protecting a slope(1) includes a non-woven fabric(10), plural stones(20), a vegetation mat(30), a metal net(40), and plural anchor members. The non-woven fabric covers the slope. The stones of which the periphery is covered with soil are installed on the upper side of the non-woven fabric. The vegetation mat covers the upper sides of the stones. The net covers the upper side of the vegetation mat. The anchor members of which the end portions are buried in the slope are connected to the net.
Abstract:
PURPOSE: An inverted wall for disaster prevention is provided to set up at the almost perpendicular state at need as a plate type wall laid along a slope of a bank body. CONSTITUTION: An inverted wall for disaster prevention is formed in the shape of a plate laid along a slope of a bank body, wherein the vicinity of the top is installed to the bank body to be rotatable freely with a rotary shaft parallel to the longitudinal direction of the bank body. The inverted wall for disaster prevention is erected by setting up using equipment which applies rotary force to a wall.
