Description

선박설계 오류검출을 위한 표준선 비교분석시스템 {Standard ship comparative analysis system for ship design error detection.}Standard ship comparative analysis system for ship design error detection.}

본 발명은 선박설계 오류검출을 위한 표준선 비교분석시스템이다. 보다 상세하게는, 선종/선형별 표준선 및 설계 규정과의 비교를 통하여 설계불량, 누락 및 구조 오류를 자동으로 검출할 수 있는 선박설계 오류검출을 위한 표준선 비교분석시스템에 관한 것이다.The present invention is a standard ship comparison analysis system for detecting ship design errors. More specifically, it relates to a standard ship comparison and analysis system for detecting ship design errors that can automatically detect design defects, omissions, and structural errors through comparison with standard ships and design regulations for each ship type/ship.

선박과 같은 대형 구조물 제작산업은 작업공기가 길고 승인절차가 복잡하며, 설계변경이 자주 된다는 특징이 있다.The manufacturing industry of large structures such as ships is characterized by a long working period, complicated approval procedures, and frequent design changes.

세계적으로 설계변경으로 인한 손실이 연간 1,364조원에 이르며, 조선해양산업에 한정한다 하더라도 44조원에 이른다. 국내 대형 3사의 설계변경으로 인한 연평균 손실금액은 915억원에 달하며 단순 설계실수, 설계누락, 자재간 충돌로 인한 간섭 등 설계오류 및 변경으로 인한 설계변경이 전체 설계변경의 73%를 차지한다.Globally, the loss due to design changes amounts to 1,364 trillion won per year, and even if it is limited to the shipbuilding and offshore industry, it can reach 44 trillion won. The average annual loss due to design changes by the three large domestic companies amounts to 91.5 billion won.

한편, 최근 가상현실기술이 디지털 기술 발전과 비용 절감의 영향으로 상용화 수준에 도달함에 따라 디지털 가상공간에 대한 수요는 점점 더 가파르게 증가하고 있다. 전 방위적으로 모든 사업 영역에서 디지털 가상공간의 동적체험이 새로운비즈니스 모델로서 새로이 적용, 개척되고 있다.Meanwhile, as virtual reality technology has recently reached the level of commercialization due to the influence of digital technology development and cost reduction, the demand for digital virtual space is increasing sharply. Dynamic experience of digital virtual space in all business areas is being newly applied and pioneered as a new business model.

조선업이 아닌 다른 산업군에서는 건설산업의 BIM, 일반 제조산업의 3D 시뮬레이터 등을 통해 다양한 시뮬레이션이 가능하나, 조선 해양산업은, 조립, 용접, 도장, 설치, 탑재, 안벽공정 등 공정의 특성으로 인하여 기존의 시뮬레이터를 적용할 수 없는 문제점이 있다.In industries other than the shipbuilding industry, various simulations are possible through BIM in the construction industry and 3D simulator in the general manufacturing industry. There is a problem that the simulator cannot be applied.

따라서, 설계단계에서 사전검사를 통해 수정/추가 사항을 선행화하여 추후 발생 가능한 설계 변경을 최소화 하고, 조립 및 탑재, 자재간 충돌 등의 각종 시뮬레이션과 AI를 이용한 설계 오류학습과 이를 활용한 설계 오류 자동검출이 가능한 솔루션이 필요한 실정이다.Therefore, it is possible to minimize design changes that may occur later by prioritizing corrections/additions through pre-inspection at the design stage. There is a need for a solution capable of automatic detection.
