아울러, 상기 진수컨디션은 dock 내에서의 선박건조가 완료된 후 선박을 최초로 수면위에 띄우는 작업을 진수라고 하는데, 이때 선박을 안전하게 진수시키기 위하여 필요한 ballast condition을 의미하고, In addition, the launching condition is called launching a ship that floats on the surface of the ship for the first time after the completion of ship construction in the dock, this time means a ballast condition necessary to safely launch the ship,
상기 DWT 측정컨디션은 계약상의 재화중랑(deadweight) 만족여부를 확인하기 위해 공선상태의 중량(lightweight)을 측정한 후 만재배수량에서 lightweight 를 빼서 deadweight를 계산한다. 이때, DWT를 측정하기 위하여 선주 / 선급에 승인받은 ballast condition을 의미한다. The DWT measurement condition calculates the deadweight by measuring the weight of the collinear state in order to confirm whether the contract deadweight is satisfied. At this time, it means the ballast condition approved by the owner / class to measure the DWT.
또한, 상기와 같은 본선펌프의 가동은 종래 진공펌프에 의한 물의 주수 및 배수에 비해 공기를 단축시킬 수 있을 뿐 만 아니라, 발라스트 탱크의 경우 배수효율을 더욱 향상시킬 수 있다. In addition, the operation of the main ship pump as described above can not only shorten the air compared to the main water and drainage of water by the conventional vacuum pump, but also can further improve the drainage efficiency in the case of a ballast tank.
또한, 상기 진수단계는 도크와 선박의 간격을 조절하여 눈금(드라프트)측정을 위한 보트의 이동공간 및 승선박스의 승하강공간을 확보하도록 되어 있다. 이때, 도크(200)와 선박(100)의 간격(L1,L2)은 도 2 에 도시된 바와 같이, 선박(100)에 연결된 케이블(300)의 길이조절을 통해 선박의 진수시 도크(200)와 선박(100)간의 간격이 자동조절된다. In addition, the launching step is to adjust the distance between the dock and the ship to ensure the moving space of the boat for the scale (draft) measurement and the lifting space of the boarding box. At this time, the interval between the
또한, 상기 진수단계는 트림(TRIM) 60~100㎝가 되도록 조절한다. 이는 선박에 ballasting 량을 최소화 하여 dock 공기를 줄이기 위한 것이다.In addition, the launching step is adjusted so that the trim (TRIM) 60 ~ 100cm. This is to reduce dock air by minimizing the amount of ballasting on the ship.
또한, 상기 진수 및 DWT 측정단계는 선박내 일측에 해치커버를 겹쳐서 탑재하는 해치커버 탑재단계를 더 포함한다. In addition, the launching and DWT measurement step further includes a hatch cover mounting step of mounting the hatch cover on one side in the ship.
상기 해치커버 탑재단계는 해치커버를 다수개씩 겹쳐서 선박 일측에 탑재 및 테크 하우징(DECK HOUSE)을 탑재하며, 이와 같은 해치커버의 탑재는 차후 선창(hold) 작업을 용이하게 하면서, 선박의 진수 및 DWT 측정을 위한 것이다. 또한, 이와 같은 해치커버의 탑재는 안벽에서의 해치커버 적재장소를 확보할 필요가 없어 안벽적치장소 부족현상을 제거할 수 있다. 또한, 이와 같은 해치커버의 적재시험은 사전에 완료하는 것이 바람직하다.In the hatch cover mounting step, the hatch cover is mounted on the ship side by stacking a plurality of hatch covers, and the deck housing is mounted on the side of the ship, and the mounting of the hatch cover facilitates hold work in the future, while launching the ship and DWT. It is for measurement. In addition, since the hatch cover is not installed, it is not necessary to secure a place for loading the hatch cover on the quay wall, thereby eliminating the shortage of the quay wall place. In addition, it is preferable to complete such a loading test of the hatch cover in advance.
상기 DWT 측정단계는 도크내에 진수된 상태에서 선박에 형성된 눈금(드라프트)를 측정하여 DWT 측정을 수행한다. In the DWT measurement step, a DWT measurement is performed by measuring a scale (draft) formed on a ship in a state launched in a dock.
이와 같이 본 발명은 본선pump작동 및 진수시 DWT측정이 가능하도록 dock 공기를 향상시키기 위하여, 부분진수시 main engine 탑재를 가능하게 하기 위한 swash BHD를 부분진수 후 그 opening을 시공하도록 되어 있다. In this way, the present invention is to construct the opening after the swash BHD to enable the main engine mounted in the partial launch, in order to improve the dock air to enable the main pump operation and DWT measurement during launch.
