Description

부유식 시추선{DRILLING SHIP}Floating Driller {DRILLING SHIP}

본 발명은 갑판을 효율적으로 이용할 수 있도록 하고, 변동 하중의 흡수 폭을 높일 수 있으며, 운동 성능이 우수한 부유식 시추선에 관한 것이다.The present invention relates to a floating drilling vessel which can make efficient use of the deck, can increase the absorption width of the variable load, and has excellent movement performance.

일반적으로, 시추선은 해양에서 원유나 가스 등을 발굴하는 장비로서, 해상 플랫폼 설치가 불가능한 심해 지역이나 파도가 심한 해상에서 원유나 가스 등의 채취 작업이 가능하도록 하고, 구조에 따라 반잠수식 시추장비(semisubmersible drilling rig)와 드릴쉽(drill ship) 있으며, 해상에서의 작업을 수행하기 위하여 고도의 제작 기술이 요구된다.In general, drilling ships are equipment for excavating crude oil or gas in the ocean, so that it is possible to collect crude oil or gas in deep sea areas where the offshore platform cannot be installed or in the sea where the waves are severe, and semi-submersible drilling equipment depending on the structure. (semisubmersible drilling rigs) and drill ships, and advanced fabrication techniques are required to perform operations at sea.

종래의 기술에 따른 시추선을 첨부된 도면을 참조하여 설명하면 다음과 같다.Referring to the drilling vessel according to the prior art with reference to the accompanying drawings as follows.

도 1은 종래의 기술에 따른 시추선을 도시한 사시도이다. 도시된 바와 같이, 종래의 기술에 따른 시추선은 한국공개특허 제1988-0007320호의 "쌍동선형 반잠수식 시추선"으로서, 2개의 선체(1,2)와 갑판(3)을 가지고, 선체(1,2)는 평행 내지 수평으로 이격되며, 갑판(3)은 선체(1,2)상에 지지되면서 선체(1,2)에 장착 구조물 에 의해 결합되고, 중앙부에 개구부(14)를 가지며, 개구부(14)는 선체(1,2) 사이의 공간 상부에 돌출한 데릭(15)에 의해 에워싸여져 있다.1 is a perspective view showing a drilling line according to the prior art. As shown, the drilling vessel according to the prior art is a "twin-linear semi-submersible drilling vessel" of Korean Patent Publication No. 1988-0007320, which has two hulls 1 and 2 and a deck 3, and the hull 1, 2) are spaced parallel to horizontally, the deck 3 is supported on the hull (1,2) and coupled to the hull (1,2) by the mounting structure, has an opening 14 in the center, 14 is enclosed by a derrick 15 protruding above the space between the hulls 1 and 2.

장착 구조물은 수직한 지주(4,5,6,7)를 가지고, 이들 중 2쌍 이상의 지주(4,5,6,7)가 선체(1,2)의 단부를 갑판(3)과 파이프 격납 장치 및 파이프 운반 장치에 결합시키고, 2개 이상의 중공 보충지주(16,17)를 가지되, 보충지주(16,17)가 잠함을 형성함과 아울러 그 내부에 파이프 격납 장치가 설치된다.The mounting structure has vertical struts 4, 5, 6 and 7, of which two or more pairs of struts 4, 5, 6 and 7 contain the deck 3 and pipe containment at the ends of the hull 1 and 2. Coupled to the device and the pipe conveying device and having at least two hollow supplemental columns 16, 17, the supplementary columns 16, 17 form a immersion and a pipe containment device is installed therein.

이와 같은 종래의 시추선은 수심 약 24m의 수중에 잠기는 것을 의도한 것으로서, 이를 위해 장착 구조물의 지주(4,5,6,7) 및 보충지주(16,17)가 잠함을 형성하게 되며, 보충지주(16,17)에 파이프 격납 장치가 설치됨으로써 장치 설치에 따른 공간 제약을 해소하도록 하였다.Such a conventional drilling ship is intended to be submerged in a water of about 24m depth, and for this purpose, the support pillars 4, 5, 6, 7 and the supplementary supports 16, 17 of the mounting structure form a lock, and the supplementary supports The pipe containment device was installed at (16, 17) to solve the space constraints caused by the device installation.

상기한 바와 같이, 종래의 기술에 따른 시추선은 반잠수식 시추 장비로 이루어짐으로써 잠함을 형성하는 복수의 지주를 가지고, 보충지주에 파이프 격납 장치를 설치하더라도 전체적인 구조가 지주와 보 형태를 가지게 됨으로써 갑판 하부의 탱크 및 장비류, 의장품 배치에 제약을 받게 되어 이러한 설비나 장비를 갑판의 상부에 배치할 수 밖에 없게 됨에 따라 갑판의 효율적인 이용이 어렵고, 시추에 필요한 각종 자재나 장비를 싣기에 필요한 하중 변동을 감당하는 폭이 제한적이라는 문제점을 가지고 있었다.As described above, the drilling vessel according to the prior art is made of a semi-submersible drilling equipment has a plurality of pillars to form a submerged, even if the pipe containment is installed in the supplementary column, the overall structure has the form of the pillar and beam deck Due to the restrictions on the arrangement of tanks, equipment, and equipment in the lower part, it is necessary to arrange such equipment or equipment on the upper part of the deck, making it difficult to use the deck efficiently and There was a problem that the breadth was limited.

또한, 드릴쉽의 경우 반잠수식 시추 장비에 비하여 큰 변동 하중을 감당할 수 있다는 장점을 가지나, 운동성능이 반잠수식 시추 장비에 비하여 떨어지고, 갑판 상부의 설비나 장비 배치에 비효율적이라는 문제점을 가지고 있었다.In addition, the drillship has the advantage that it can handle a large fluctuation load compared to the semi-submersible drilling equipment, but the movement performance is lower than that of the semi-submersible drilling equipment, and inefficient in the arrangement of equipment or equipment on the upper deck. .

본 발명은 상기한 문제점들을 해결하기 위하여 안출된 것으로서, 운동성능이 뛰어나면서도 갑판 상부의 자재나 장비 배치에 효율적이다.The present invention has been made to solve the above problems, it is excellent in athletic performance and efficient in the arrangement of materials or equipment on the upper deck.
