Description

터렛 진원도 확보용 지그 및 그를 이용한 터렛 시공방법{Jig for maintaining turret circularity and Method for turret installation using the same}Technical Field [0001] The present invention relates to a jig for securing a roundness of a turret and a turret construction method using the same,

본 발명은 해양호선용 터렛의 진원도 확보에 관한 것으로서, 보다 구체적으로는 FPSO와 같은 해양호선의 터렛 시공 과정에서 변형방지 지그 이용과 소모듈 용접으로 인한 열변형을 최소화하면서 진원도 정도를 유지하는 터렛 진원도 확보용 지그 및 그를 이용한 터렛 시공방법에 관한 것이다.The present invention relates to securing the roundness of a turret for a marine vessel, and more particularly, to a turret roundness maintaining the degree of roundness while minimizing thermal deformation due to the use of a deformation prevention jig and a small module welding in a turret construction process of a marine vessel such as FPSO And a turret construction method using the jig.

해양호선(FPSO)의 터렛 구조물은 선체를 관통해서 해저와 연결되고 해상 상황에 따라 회전하는 축받이 역할을 하면서 안정적 가스 운송을 도모한다. 터렛 구조물의 구성품인 F.H.S(Free Hanging Structure)는 조립 작업 시 대형 원통 구조물의 진원도 유지가 상당히 중요하다. The turret structure of the marine ship line (FPSO) penetrates the hull and is connected to the seabed. F.H.S (Free Hanging Structure), which is a component of the turret structure, is very important to maintain the roundness of the large cylindrical structure during assembly work.

종래에는 터렛 실린더 플레이트 대모듈을 φ22000 대형 원통 플레이트로 제작 후 세팅하여 각각의 중소모듈을 탑재하고 용접하므로 열변형과 진원도를 확인하면서 정도를 유지해야 한다. 이때 도 1의 부호 10으로 나타내는 것처럼 (+)자 모양의 보강재(H-BEAM, PIPE)가 진원도 유지를 위해 임시 설치되었다가 작업 및 운송 후 철거된다.Conventionally, the turret cylinder plate module is manufactured by φ22000 large cylindrical plate, and each small and medium module is mounted and welded. Therefore, it is necessary to maintain the accuracy while checking the thermal deformation and roundness. At this time, a (+) shaped stiffener (H-BEAM, PIPE) is temporarily installed to maintain the roundness as indicated by reference numeral 10 in FIG.

그러나, 보강재가 받혀지지 않은 곳에는 진원도를 유지하며 작업하기 어려움이 따르고, 진원도 확인을 위한 대기 공수 및 재작업 상황이 발생되며, 보강재 철거 시에도 원통 내부에 있어 작업의 어려움과 변형 발생의 우려가 있다.However, where the reinforcement is not received, it is difficult to maintain the roundness, it is difficult to work, and atmospheric air and rework conditions occur to confirm the roundness. Also, when the reinforcement is demolished, have.

선행특허의 일예로서, 한국 등록특허공보 제1059998호는 선체를 구성하는 대형블록을 조립하는 방법으로서, 제1크레인이 설치된 제1작업장으로 중형블록을 이동하는 단계; 상기 제1크레인을 이용하여 상기 중형블록을 턴오버시키는 단계; 주판을 지지부재에 적재하는 단계; 상기 주판을 적재한 상태로 상기 제1작업장으로 이동하는 단계; 및 상기 중형블록을 상기 주판과 결합시켜 대형블록을 형성하는 단계를 포함한다. 이에 따라, 별도의 지그 정반의 조성 없이도 대형블록을 조립하는 효과를 기대한다.As an example of the prior patent, Korean Patent Registration No. 1059998 discloses a method for assembling a large block constituting a hull, comprising the steps of moving a middle block to a first work site provided with a first crane; Turning over the middle block using the first crane; Loading the abacus on a supporting member; Moving to the first worksite in a state in which the main plate is loaded; And joining the mezzanine block with the abacus to form a large block. Accordingly, the effect of assembling a large block can be expected without forming a separate jig base.

그러나, 상기한 방식을 해양호선(FPSO)의 터렛 구조물의 제조에 적용하는 경우 부분적인 중모듈은 물론 전체적인 대모듈의 진원도를 확보하기 곤란하므로 품질과 생산성을 크게 저하시키는 요인으로 작용한다.However, when the above-described method is applied to the fabrication of the turret structure of the marine arcs (FPSO), it is difficult to secure the roundness of the entire middle module as well as the partial middle module.

The first jig 35 is formed to support the inner surface of the turret by engagement pieces 56 provided at a plurality of points. The second jig 45 is coupled adjacent to the first jig 35 and supports the inner surface of the turret to the ring plate 58 at a plurality of points. The first jig (35) and the second jig (45) support the cylinder plate (25) constituting the inner surface of the turret. The cylinder plate 25 is included in the small module 20 together with the arc plate 21 and the flat plate 22.

도 2a와 같은 제1지그(35)의 경우 H빔(52) 상으로 다수의 파이프(54)가 결합되고, H빔(52)과 파이프(54)의 단부에 각각의 결합편(56)을 지닌다. 결합편(56)의 위치 좌표는 실린더플레이트(25)에서 지지할 부분의 좌표와 일치시킨다. 도 2b와 같은 제2지그(45)의 경우 H빔(52) 상으로 다수의 파이프(54)가 결합되고, H빔(52)과 파이프(54)의 단부를 링플레이트(58)로 연결한다. 링플레이트(58)의 위치 좌표는 실린더플레이트(25)에서 지지할 부분의 좌표와 일치시킨다. 제1지그(35)와 제2지그(45)는 소모듈(20)과 가용접되므로 동일한 소재를 사용하는 것이 좋다.A plurality of pipes 54 are coupled onto the H beam 52 in the case of the first jig 35 as shown in FIG. 2A, and respective engaging pieces 56 are attached to the ends of the H beam 52 and the pipe 54 I have.

The position coordinates of the ring plate 58 are made to coincide with the coordinates of the portion to be supported by the cylinder plate 25. [ Since the first jig 35 and the second jig 45 can be touched with the small module 20, it is preferable to use the same material.

이때, 본 발명에 따르면 상기 복수의 제1지그(35)와 제2지그(45)는 하나의 지그체(50)를 이루는 것을 특징으로 한다. 지그체(50)는 소모듈(20)을 구성하는 다수의 호형판(21), 평판(22), 실린더플레이트(25)를 지지하여 중모듈(30)을 완성하는 과정에서 진원도(진원 φ22000에 ㅁ 5mm 허용공차)를 유지한다.According to the present invention, the plurality of first jigs 35 and the plurality of second jigs 45 constitute one jig 50. The jig member 50 supports the plurality of arc-shaped plates 21, the flat plate 22 and the cylinder plate 25 constituting the small module 20 to complete the middle module 30, ㅁ 5mm tolerance).

As shown in FIG. 6, when the middle module 30 is set to 1/4 the size of the turret, only the circumferential length is reduced and the overall height remains the same. The jig body 50 includes a plurality of first jig 35 and second jig 45 over the entire height and includes a second jig 45 at the upper and lower ends thereof and a first jig 35 at a predetermined interval . In this way, even when the intermediate first jig 35 is removed during the construction of the turret, the required joint strength and roundness can be maintained with only the second jig 45 at the upper and lower ends.

본 발명의 다른 일면에 의하면, 청구항 1의 지그체(50)를 이용하여 원통형 구조물인 터렛의 진원도를 확보하기 위한 시공방법에 관련된다. According to another aspect of the present invention, there is provided a construction method for securing the roundness of a turret which is a cylindrical structure by using the jig (50) of claim 1.

본 발명의 단계 (a)는 제1지그(35)와 제2지그(45)를 결합하여 지그체(50)를 완성하는 과정으로 시작한다. 제1지그(35)와 제2지그(45)의 구성과 지그체(50)를 완성하는 방식은 전술한 도 2 및 도 3의 설명을 참조한다. 해양호선(FPSO)의 터렛은 소모듈(20), 중모듈(30), 대모듈(40)의 과정으로 완성되며, 이 과정에서 제1지그(35)와 제2지그(45)의 설치와 제거가 개별적으로 진행된다.Step (a) of the present invention starts with the process of completing the jig 50 by joining the first jig 35 and the second jig 45 together. The construction of the first jig 35 and the second jig 45 and the manner of completing the jig 50 are described with reference to FIGS. 2 and 3 described above. The turret of the marine ship FPSO is completed by the process of the small module 20, the middle module 30 and the large module 40. In this process, the installation of the first jig 35 and the second jig 45 The removal is done separately.

본 발명의 단계 (b)는 상기 지그체(50) 상에 터렛의 소모듈(20)을 결합하여 중모듈(30)을 완성하는 과정을 거친다. 소모듈(20)은 다수의 호형판(21), 평판(22), 실린더플레이트(25)를 의미하며, 이러한 부재들이 설정된 형태로 집합되어 도 5와 같은 중모듈(30)이 완성된다. 물론 중모듈(30)은 이전 단계에 설정된 지그체(50)에 대응하는 크기로 형성된다.The step (b) of the present invention is a process of completing the middle module 30 by coupling the small module 20 of the turret onto the jig body 50. The small module 20 means a plurality of arc plates 21, a flat plate 22 and a cylinder plate 25 and these members are assembled in a predetermined form to complete the middle module 30 shown in FIG. Of course, the middle module 30 is formed in a size corresponding to the jig body 50 set in the previous step.

이때, 상기 단계 (b)의 중모듈(30)은 설정된 형태의 실린더플레이트(25) 상에 이에 대응하는 호형판(21)과 평판(22)을 결합하는 것을 특징으로 한다. 도 5처럼 지그체(50)의 곡면이 상측으로 가도록 엎어 놓은 상태에서 이미 곡면 성형된 실린더플레이트(25)를 상치하고 용접으로 고정한 다음 실린더플레이트(25)에 호형판(21)과 평판(22)을 순차적으로 용접하여 고정한다. 이와 같은 방식으로 완성된 중모듈(30)은 다수의 용접을 거치더라도 진원도가 정확하게 유지된다.At this time, the module 30 in the step (b) is characterized in that the ring plate 21 and the plate 22 corresponding to the cylinder plate 25 of the set type are coupled to each other.
