Abstract

The present invention is characterized by installing a watertight sliding door of a semi-submersible heavy cargo transport vessel and a hydraulic test chamber to cover the outer side of the whole operation section where the watertight sliding door is opened and closed on the outer wall of the transport vessel and enabling a hydraulic test to last for a predetermined period by supplying a pressure fluid to the hydraulic test chamber in the same condition as on the sea. The present invention can check malfunctions in the sliding door before launching (sailing) the vessel by independently performing a hydraulic test for the sliding door right after the watertight sliding door of the semi-submersible heavy cargo transport vessel is assembled. Therefore, the present invention can take precautions before problems, thereby reducing a period of constructing the semi-submersible heavy cargo transport vessel.

Description

수밀 슬라이딩 도어의 수압테스트 방법{METHOD FOR HYDRAULIC TEST OF WATERTIGHT SLIDING DOOR}METHOD FOR HYDRAULIC TEST OF WATERTIGHT SLIDING DOOR [0001]

본 발명은 수밀 슬라이딩 도어의 수압테스트 방법에 관한 것으로서, 보다 상세하게는 반잠수식 중량물 운반선의 수밀 슬라이딩 도어의 수압테스트하기 위한 수압테스트 방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water pressure test method for a watertight sliding door, and more particularly, to a water pressure test method for hydraulic test of a watertight sliding door of a semi-submersible heavy-goods carrier.

일반적으로 해양구조물처럼 화물이 크고 무거운 것을 운반하는 선박을 반잠수식 중량물 운반선(semi submersible ship)이라 한다.In general, a ship carrying large and heavy cargoes, such as offshore structures, is called a semi-submersible ship.

이와 같은 반잠수식 중량물 운반선은 선박에 화물을 적재 하지 않은 상태로 운항을 할 경우, 해수를 선박 내에 위치한 밸러스트 탱크 내로 유입시켜 선박의 안정적인 운항을 위하여 요구되는 흘수를 확보하게 된다. 또한, 화물을 적재해야 하는 항구에서는 밸러스트 수를 선체 밖으로 배수함으로써 더 많은 화물을 적재할 수 있도록 한다.In case of semi-submersible heavy cargo ships, when the ship is operated without loading cargo, sea water is introduced into the ballast tanks in the ship to secure the required draft for stable operation of the ship. Also, in harbors where cargo is to be loaded, ballast water is drained out of the hull so that more cargo can be loaded.

이와 같은 반잠수식 중량물 운반선은 잠수구역 내에 외부와 통하는 슬라이딩 도어를 설치하게 된다.Such a semi-submersible heavy-goods carrier is provided with a sliding door communicating with the outside in the diving area.

상기한 바와 같은 슬라이딩 도어는 선박의 안전사고와 직결되기 때문에 수밀 테스트가 엄격하게 진행된다.Since the sliding door is directly connected to the safety accident of the ship, the watertightness test is strictly proceeded.

그러나, 종래에는 이와 같은 슬라이딩 도어의 수압 테스트를 운반선의 건조 후, 실제 해상에서 테스트하게 되는 것으로서, 테스트에 많은 시간이 소요될 뿐만 아니라, 테스트 과정에서 잘못된 부분이 발견될 경우에도 이를 보완하는데 많은 시간과 노력이 소요되는 문제가 있었다.
However, in the past, such a hydraulic pressure test of a sliding door has been tested in actual sea after drying of a carrier, so that it takes a lot of time for testing, and even if a wrong part is found in the test process, There was a problem that effort required.

대한민국 공개특허 제10-2013-0015262호Korean Patent Publication No. 10-2013-0015262

이때, 상기 수압테스트 챔버(120)는 일면이 개구된 금속 압력용기로서 제작될 수 있는데, 보다 바람직하게는 사각함체로 제작될 수 있다.At this time, the hydraulic test chamber 120 may be manufactured as a metal pressure vessel having one side opened, more preferably, a rectangular housing.

이와 같은 수압테스트 챔버(120)의 개구면이 운반선 외벽(110)에 밀착되도록 한 상태에서 접지면 둘레를 용접에 의해 밀봉되도록 한다.The opening surface of the hydraulic test chamber 120 is closely contacted with the outer wall 110 of the carrier so that the periphery of the ground surface is sealed by welding.

이후, 상기 수압테스트 챔버(120) 내에 해상 조건에서와 동일한 압력유체를 공급하여 일정시간 수압테스트가 이루어지도록 하는데, 압력유체는 해수 및 청수를 이용할 수 있으며, 해상 조건에서와 동일한 수압을 제공하기 위한 별도의 압력장치(콤푸레샤 등)를 구성할 수 있다.Thereafter, the same pressure fluid as in the sea condition is supplied to the hydraulic test chamber 120 so that a hydraulic pressure test is performed for a predetermined time. The pressure fluid may use seawater and fresh water, A separate pressure device (such as a compressor) can be constructed.

이때, 상기 수압테스트 챔버(120)의 상부에는 압력유체 공급부(121)를 형성하고, 하부에는 압력유체 배출부(123)를 형성할 수 있다.At this time, a pressure fluid supply part 121 may be formed on the upper part of the hydraulic test chamber 120, and a pressure fluid discharge part 123 may be formed on the lower part.

상기한 바와 같은 방법으로 슬라이딩 도어(113)의 수압테스트가 끝나게 되면, 수압테스트 챔버(120) 내의 압력유체를 압력유체 배출부(123)를 통해 배출한 후 수압테스트 챔버(120)를 해체하게 된다.When the water pressure test of the sliding door 113 is completed in the above-described manner, the pressure fluid in the water pressure test chamber 120 is discharged through the pressure fluid discharge unit 123, and then the water pressure test chamber 120 is disassembled .

이때, 수압테스트 챔버(120)의 둘레에 용접된 밀봉부를 절단기를 이용해 절단함으로써, 수압테스트 챔버(120)를 해체할 수 있게 된다.At this time, the watertight test chamber 120 can be disassembled by cutting the seal portion welded around the hydraulic test chamber 120 using a cutter.

상기한 바와 같은 본 발명은 반잠수식 중량물 운반선의 수밀 슬라이딩 도어가 조립된 직후에 슬라이딩 도어만을 개별 수압 테스트함으로써, 진수 전에도 슬라이딩 도어의 이상유무를 확인할 수 있고, 이로써 문제발생 전에 사전조치가 가능하기 때문에 반잠수식 중량물 운반선의 건조기간을 단축할 수 있는 효과를 갖는다.As described above, according to the present invention, it is possible to check whether or not the sliding door is abnormal even before the start of the water pressure test by individually testing only the sliding doors immediately after the water-tight sliding doors of the semi-submersible heavy-goods carrier are assembled. Therefore, the drying period of the semi-submerged heavy goods carrier can be shortened.
