Abstract

The buoy-enabled underwater surveillance system is a device that is installed in a particular sea area and operated for a certain period of tine and moved to another sea area after recovery. In this paper, a mooring method which is applied for a buoy-enabled underwater surveillance system was selected to maintain installation and enure stable operation. Also, the structure of the mooring line was designed. Two-point mooring method was selected considering interference with the communication cable of array-assembly. The composite structure of buoy chain, nylon rope, and anchor chain is designed as the basic component of mooring line. For the verification of design, a numerical simulation and wave tank experiment were performed. Their results were confirmed similarity in test condition. Finally, the mooring lines were designed for the environment of the sea trial location. The mooring line produced by the final design confirmed the stability above the significant wave height considered in the design on the sea trial.

부이형 수중감시 시스템은 필요시 특정해역에 설치되어 일정기간 운용하고 회수이후, 다른 해역으로 이동하여 수중감시를 수행하는 장비이다. 본 논문에서는 부이형 수중감시 시스템에 적용되는 계류라인에 대하여 설치성을 유지하고 안정적인 운용이 가능하도록 계류방법을 선정하고 계류라인의 구조를 설계하였다. 부이형 수중감시 시스템의 구성요소인 배열센서조립체의 신호전송 케이블의 간섭을 고려하여 2점 계류방법을 선정하였고, 계류라인은 해역 이동에 따른 설치/회수성을 고려하여 부이체인, 나일론 로프, 그리고 앵커체인의 3단 복합구조를 기본 구성으로 설계하였다. 설계 유효성을 검증하기 위하여 수치실험과 조파수조 시험을 수행하여 유사성을 확인하였으며, 최종적으로 해상시험 위치의 환경을 대상으로 계류라인의 설계를 수행하였다. 최종 설계에 의해 제작된 계류라인은 해상시험을 통하여 설계 시 고려한 유의파고 이상에서도 안정적인 계류를 수행함을 확인하였다.
