It relates to a subsea installation protection duct to ensure ductility.

일반적으로, 해저시설물은 대륙과 대륙, 육지와 섬 등과 같이 바다를 사이에 두고 격리된 두 지점 사이의 해저에 설치되는 것으로, 가스와 석유 등의 이송을 위한 송유관, 심층수 파이프, 통신을 위한 케이블 등이 있으며, 해저에 부설되기 때문에 어업활동이 활발한 지역에서는 선박의 닻이나 어구(漁具) 등에 의해 시설물이 손상되기 쉽고 해류나 파랑(波浪)에 의한 해풍사태, 해저면과의 마찰 등 자연현상에 의해서도 시설물이 손상되므로 이를 막기 위한 대책이 요구된다.In general, subsea facilities are installed on the sea floor between two points separated from the sea such as continents and continents, land and islands, such as oil pipelines for the transport of gas and oil, deep water pipes, cables for communication, etc. In the area where fishing activity is active because of being installed on the bottom of the sea, facilities are easily damaged by anchors and fishing vessels of ships, and also due to natural phenomena such as sea storms caused by currents or waves, and friction with sea floor. The facility is damaged and measures are required to prevent it.

그 대책의 일환으로 시설물의 외측에 보호 덕트를 설치하고 있으며, 보호 덕트에 대한 선행기술로는 실용신안등록 256926호에는 서로 맞물리는 안착부와 요홈을 안착부와 요홈에 각각 대응되게 천공된 구멍 내로 삽입되는 핀으로 체결한 기술이 공고되어 있으나, 상기한 선행기술은 안착부와 요홈에 각각 구멍을 천공하고 이들 구멍을 동심원상으로 일치시켜야 하므로 가공중 발생가능한 성형 오차로 인하여 치수가 정확하게 일치하지 않을 경우에는 위치를 일치시켜야 하므로 해저에서의 작업이 원활하지 않게 되고, 상기한 구성으로 별도의 핀을 삽입하여야 하므로 작업과정이 번거로운 문제점이 있었다.As part of its countermeasures, protective ducts are installed on the outside of the facility.As a prior art for protecting ducts, Utility Model Registration No. 256926 registers the seating and grooves interlocking with each other into holes drilled to correspond to the seating and grooves, respectively. Although the technique of fastening with the pin to be inserted is publicly disclosed, the above-described prior art has to drill holes in the seating part and the recess respectively and coincide these holes concentrically so that the dimensions may not be exactly matched due to the molding error that may occur during processing. In this case, since the position must be matched, the work on the seabed is not smooth, and since the separate pin must be inserted in the above configuration, the work process is cumbersome.

또한, 상기한 바와 같이 치수 오차가 발생할 경우 구멍을 동심 상으로 일치시키기가 어려워서 안착부와 요홈은 치수에 정밀도를 요하므로, 체결로 인하여 직 선모양은 가능하지만 해저시설물의 곡선 설치구간에 맞게 굴곡 배치는 불가능하였다.In addition, as described above, it is difficult to match the holes concentrically in the case of a dimensional error, so the seating portion and the groove require precision in the dimensions, so that the linear shape is possible due to the fastening, but bent to the curved installation section of the seabed facility. Deployment was impossible.
