Abstract

PURPOSE: A high efficient bilge keel is provided to restrict rolling of a ship, to improve the performance, and to design the design of the ship conveniently by mounting various bilge keels in the low speed ship or a marine structure. CONSTITUTION: A bilge keel(10) is installed in the bottom of a ship to restrict rolling of the ship, and protruded out of the extension line of the bottom of the ship. Structures having various sections are connected and mounted in the ends of the bilge keels to increase the damping coefficient. The bilge keel is mounted in the low speed ship or the marine structure, and protruded without limit of length. The low speed ship and the marine structure cruise against obstacles from the length of the bilge keel. The lift is used around the end of the blade in rolling the ship with connecting the hydrofoil section structure to the end of the ship. Rolling is restricted with mounting bilge keels including various sections in the ship.

고효율 빌지 킬{High-efficiency Bilge Keels}High-efficiency Bilge Keels

본 발명은 고효율 빌지 킬(Bilge Keels)에 관한 것으로, 속도가 느린 선박이나 해양구조물 및 FPSO 등의 바닥면에 설치되어 롤 운동을 억제할 수 있는 고효율 빌지 킬에 관한 것이다.The present invention relates to a high efficiency bilge keels, and relates to a high efficiency bilge keel that can be installed on the bottom surface of a slow ship, offshore structure, FPSO, etc. to suppress roll motion.

일반적으로 롤 운동은 선박이나 해양구조물의 작업성능 측면에서 중요한 설계인자로 대두되고 있으며, 선박 및 해양구조물의 롤 운동은 대부분 공진 주기에서의 감쇠에 따라 결정되어 진다.In general, roll motion has emerged as an important design factor in terms of work performance of ships and offshore structures, and roll motion of ships and offshore structures is mostly determined by attenuation in the resonant period.

종래에는 상기와 같은 롤 운동을 억제하기 위하여 도 17 에 도시된 바와 같이 단순한 직선형상의 빌지 킬을 단면의 폭과 바닥면 내에서만 제한된 길이로 부착하였다. 그러나, 상기와 같이 단순한 형상을 구비하고, 그 길이가 제한되어 있어, 선박에서의 롤 운동을 감소시키는데 그리 큰 역할을 하지 못하는 등 여러 가지 문제점이 있었다.Conventionally, in order to suppress the roll motion as described above, as shown in FIG. However, there are a variety of problems, such as having a simple shape as described above, the length is limited, does not play a large role in reducing the roll motion in the ship.

본 발명은 상기와 같은 문제점을 고려하여 이루어진 것으로, 그 목적은 속도가 느린 선박이나 해양구조물 및 FPSO 등에 여러 가지 형상을 구비하는 빌지 킬을 부착하여 선박의 롤 운동을 크게 감소할 수 있는 고효율 빌지 킬을 제공하는 것이다.The present invention has been made in view of the above problems, and an object thereof is to attach a bilge kill having various shapes to a slow ship or offshore structure and FPSO to effectively reduce the roll motion of the ship. To provide.

본 발명은 선박의 롤 운동을 억제하기 위하여 바닥면에 설치되는 빌지 킬에 있어서; 상기 빌지 킬은 폭과 바닥면의 연장선 밖으로 돌출되도록 부착하고, 상기 빌지 킬의 끝단부에 독특한 단면형상을 구비하는 여러 가지 구조물을 설치하여 감쇠계수를 크게 할 수 있는 고효율 빌지 킬을 제공함에 있다.The present invention is a bilge kill installed on the bottom surface to suppress the roll motion of the ship; The bilge kill is attached to protrude outside the extension line of the width and the bottom, and to provide a high efficiency bilge kill to increase the damping coefficient by installing a variety of structures having a unique cross-sectional shape at the end of the bilge kill.
