Description

비선형 계류 모사장치Nonlinear mooring simulator
본 발명은 계류 모사장치에 관한 것으로, 보다 상세하게는 전후운동, 좌우운동에 대한 복원력을 전달하며 상하운동은 터렛의 등가 질량을 이용해 선박의 상하운동을 허용할 수 있으며, 모형수조의 특성상 수선면 아래에 모형계류선을 설치할 수 없는 수조시험시 계류선의 특성을 기존에 비해 보다 정교하게 모사할 수 있는 비선형 계류 모사장치에 관한 것이다.The present invention relates to a mooring simulation device, and more particularly, it transmits a resilience to the back and forth motion and left and right motion, and the vertical motion can allow the vertical motion of the ship using the equivalent mass of the turret. The following relates to a nonlinear mooring simulation device that can more accurately simulate the characteristics of a mooring ship in a tank test where a model mooring ship cannot be installed.
일반적으로 선박 또는 구조체 등 거대한 장치 등은 기본 설계 단계에서 수중 운동 등에 대한 성능을 만족하는가에 대하여 시뮬레이션 시험이 필수적이다.In general, a simulation test is essential for a large device such as a ship or structure to see if it satisfies the performance for underwater motion at the basic design stage.
모형시험은 실제의 물리적인 현상을 축소된 실험실에서 동일하게 재현함으로써 모형시험에서 계측하여 해석한 값을 실선단위로 확장 가능하게 함을 목적으로 하는바, 관찰하고자 하는 현상을 지배하는 물리적 상사법칙을 만족하도록 모델링(modelling)을 하는 것이 중요하며, 이는 차원해석을 통하여 물리적 의미를 갖는 무차원수를 추출함으로써 가능해진다.The purpose of the model test is to reproduce the actual physical phenomena identically in a reduced laboratory, so that the measured and analyzed values in the model test can be expanded in units of solid lines. It is important to model to be satisfied, and this is made possible by extracting non-dimensional numbers having a physical meaning through dimensional analysis.
한편, 모형시험은 다양한 목적에 따라 다양한 형태로 수행될 수 있는데, 그 중에서도 본 발명과 관련한 계류력 성능평가시험은 선박이나 해양구조물 등 부유체의 위치유지를 위한 시험이다.On the other hand, the model test can be performed in various forms according to various purposes. Among them, the mooring force performance evaluation test related to the present invention is a test for maintaining the position of a floating body such as a ship or an offshore structure.
부유체는 위치를 유지하기 위해 다양한 계류시스템(일점 계류, 다점 계류, 터렛 등)이 사용될 수 있으며, 계류시스템은 설치 해역의 환경, 구조물의 종류, 비용 등의 조건을 고려해 결정된다. 일점 계류 방식은 환경 외력에 따라 선수각이 자유롭게 회전하여 부유체에 작용하는 하중을 감소시킬 수 있기 때문에 가혹한 환경 조건에서 주로 사용되고 있으며, 터렛 계류는 대표적인 일점 계류 방식이다.Various mooring systems (single-point mooring, multi-point mooring, turret, etc.) can be used to maintain the floating body, and the mooring system is determined in consideration of conditions such as the environment of the installation sea area, the type of structure, and cost. The one-point mooring method is mainly used in severe environmental conditions because the bow angle rotates freely according to the external force of the environment, thereby reducing the load acting on the floating body, and turret mooring is a representative one-point mooring method.
극지역에 설치되어 운용되는 해양구조물의 위치유지를 위한 계류시스템의 설계 및 성능평가를 위한 모형시험은 빙해수조를 생성하고 빙해수조의 수면 위에서 이루어지며, 모형시험용 빙해 생성을 위해 수조 바닥에 다수의 빙해 생성 관련 설비들이 구비된다. 따라서 빙해수조는 특성 상 빙해 생성을 위한 수조 바닥에 구비된 관련 설비로 인하여 일반적인 계류시스템의 구현이 어렵다.The model test for the design and performance evaluation of the mooring system for maintaining the position of the offshore structures installed and operated in the polar region is conducted on the surface of the ice tank by creating an ice water tank. Facilities related to ice formation are provided. Therefore, it is difficult to implement a general mooring system due to the characteristics of the ice water tank, due to the related facilities provided at the bottom of the water tank to generate ice sea.
이에 대하여 특허문헌 1(KR 10-2019-0071138 A)은 메인프레임과, 상하 높이방향의 자유도를 갖는 히브축과, 메인프레임에 좌우 길이방향 구비되는 스웨이레일과, 스웨이레일의 좌우 말단에 각각 구비되는 스웨이고정부와, 메인프레임에 전후 길이방향으로 구비되는 서지레일과, 서지레일의 전후 말단에 각각 구비되는 서지고정부와, 상기 히브축과 일측이 연결되고 거치고정수단이 구비된 자중보상장치와, 스웨이고정부와 서지고정부의 하부에 각각 연결된 가이드아답터를 포함하는 비선형 계류 모사장치를 제안하였다.On the other hand, Patent Document 1 (KR 10-2019-0071138 A) is provided on the main frame, the heave shaft having a degree of freedom in the vertical and vertical directions, the sway rail provided in the left and right longitudinal directions on the main frame, and the left and right ends of the sway rail, respectively.

그러나, 종래는 수중에 발생하는 계류 저항의 다양한 변화를 모두 적용하기에 부족하여 실질적으로 정확한 계류 상태를 모사하기 어려운 문제점이 있다.However, there is a problem in that it is difficult to simulate a practically accurate mooring state because it is insufficient to apply all various changes in mooring resistance occurring underwater.
위와 같은 점을 감안하여 발명된 본 발명의 목적은, 수면하 공간에 어떠한 설비도 필요하지 않는 비선형 계류 모사장치를 제공하는 것이다.It is an object of the present invention in view of the above points to provide a nonlinear mooring simulation device that does not require any equipment in the space under the water surface.
또한, 정밀한 측정이 가능한 비선형 계류 모사장치를 제공하는 것이다.In addition, it is to provide a nonlinear mooring simulation device capable of precise measurement.
