Description

안전성이 향상된 알루미늄 합금 선박 충돌 방지 시스템{SHIP} Aluminum alloy ship collision prevention system with improved safety{SHIP}

본 발명은 충돌 방지 시스템에 관한 것으로, 보다 상세하게는 안전성이 향상된 알루미늄 합금 선박 충돌 방지 시스템에 관한 것이다.The present invention relates to an anti-collision system, and more particularly, to an aluminum alloy ship anti-collision system with improved safety.

선박 사고의 대부분은 선박 간의 충돌 또는 선박과 고정 장애물 간의 충돌에 의한 충돌 등 충돌 사고가 대부분으로, 최근 선박의 크기가 대형화되고 선박의 종류가 다양화됨에 따라, 선박 충돌 사고로 인한 인명 피해, 재산피해 및 해양 오염과 같은 2차적 피해 등 대규모 피해가 발생하고 있다.Most of ship accidents are collisions such as collisions between ships or collisions between ships and fixed obstacles, and as the size of ships has recently increased and the types of ships are diversified, human damage and property due to ship crash accidents Large-scale damage is occurring, such as damage and secondary damage such as marine pollution.

선박 충돌 사고는 주로 선박의 출입이 잦은 항만 부근 및 연안 해역에서 발생하기 때문에, 종래에는 이와 같은 해역에서의 선박 및 고정 장애물에 대해 AIS(Automatic Identification System) 데이터, PTMS(Port Traffic Management System) 데이터 또는 ECDIS(Electronic Chart Display and Information System) 데이터를 VTS 관제사, 도선사 또는 선박 운항자들에게 제공하고 있다. 또한, 국제해사기구(IMO)의 협약에 따라 2002년부터 300톤 이상의 국제항해 선박 및 500톤 이상의 국내항해 선박은 AIS 장비의 의무 장착이 시행되었으며, 시행 결과의 효과의 유익성이 관련 보고서로 증명되고 있다.Since ship collision accidents mainly occur near ports and coastal waters where ships are frequently accessed, conventionally, AIS (Automatic Identification System) data, PTMS (Port Traffic Management System) data or ECDIS (Electronic Chart Display and Information System) data is provided to VTS controllers, pilots or ship operators. In addition, in accordance with the agreement of the International Maritime Organization (IMO), since 2002, international voyage vessels over 300 tons and domestic voyage vessels over 500 tons have been obligated to install AIS equipment. Has become.

이에 반하여, 선박 충돌 사고의 대부분(70%)이 육지와 가까운 연안에서 100톤 미만의 중소형 선박에 의해 발생했으며(해양안전심판원, 2003년~2008년), 이는 인명(31%)과 재산, 환경 사고로 연결되고 있다.On the other hand, most (70%) of ship collision accidents were caused by small and medium-sized ships weighing less than 100 tons off the coast near the land (Marine Safety Judge, 2003-2008), and this was due to human life (31%), property, and environment. Leading to an accident.

그러나 기존의 FRP 재질로 만들어지는 소형 선박의 경우 FRP 재질 특성상 센서를 설치하기 위한 홀을 형성하려면 별도의 프레임을 설치하거나 선박 자체에 홀을 형성하여야 하는데 FRP 재질 특성상 용접이 어려움이 있다.그리고 전기 케이블 트레이를 설치하기에도 어려움이 있다.However, in the case of small ships made of conventional FRP material, in order to form a hole for installing the sensor due to the nature of the FRP material, a separate frame must be installed or a hole must be formed in the ship itself, but welding is difficult due to the nature of the FRP material. There are also difficulties in installing the tray.
