본 연구는 2008년 범선 및 플레저보트 검사지침 이후 국내의 플레저보트 관련 검사기준의 변화과정을 살펴보고 2009년 9월 새로이 제정된 플레저보트 검사치침과 국제표준화기구 (ISO)의 소형선박분야 기술위원회(TC188)에서 제정한 플레저보트 관련 국제표준의 주요내용을 비교 검토함으로써 관련규정에 대한 사용자의 이해를 높이는 동시에 향후 국내 플레저보트 검사지침의 개선방향을 검토하기 위하여 추진되었다.

국제표준규격(ISO 12215-5) 및 국내 플레저보트 검사지침의 개정에 따라 길이 6미터 미만의 플레저보트의 낙하시험에 의한 강도시험기준을 적용 가능하게 되었다. 하지만 현재 낙하시험은 자유낙하 시 내력 및 외력에 의한 선체 내부의 찌그러짐, 크랙, 박리, 파손 등을 육안으로 검사하는 방법으로 시험결과의 정량적인 판단이 이루어지지 않고 있다. 따라서 본 연구에서는 레저선박의 낙하시험을 위한 시스템 및 운용프로그램을 개발하여 플레저보트의 구조안전성의 정량적 평가가 가능한 시스템을 개발하고 다단 롤포밍 기법을 적용한 5m급 알루미늄레저보트에 적용하여 시스템의 성능을 검증하였다.

The structural safety of small craft, such as steel ships and FRP ships, can be estimated using the measurement test of the hull plate thickness or the longitudinal bending strength test. A polyethylene boat is made using inexpensive HDPE and can be mass produced. The structural safety of a polyethylene boat cannot be guaranteed because a polyethylene boat hull is notspecified in the KR technical rules. The inspection procedure of sailing yachts and pleasure boats and drop test method of ISO standard 12215-5 propose the structural strength required for small crafts as the drop test height. Therefore, in this study, the drop test of a polyethylene boat hull was carried out based on the inspection procedure of a sailing yacht and pleasure boat and the drop test method of ISO standard 12215-5. The drop load was acquired by the drop acceleration ofa boat hull. Structural analysis and safety of a polyethylene boat were performed by the drop load and allowable stress criteria. The calculation results of the hull plate thickness by structural design specification of ISO standard 12215-5 showed that polyethylene boat hull was more than two times thicker than a steel ship hull and the boat hull determined by the inspection procedure of sailing yacht and pleasure boat and drop test method of ISO standard 12215-5 was more than 1.2 times thicker than the boat hull determined by structural design specification of ISO standard 12215-5. Therefore, inspection procedure of sailing yachts and pleasure boats and drop test method of ISO standard 12215-5 was much more conservative than the structural design specification of ISO standard 12215-5 and could be used as the structural design method of a polyethylene boat.

International Organization for Standardization has recently published ISO 12215-5 which is the small craft-hull construction and scantling. According to ISO 12215-5 AnnexB, the scantling determination can be accomplished by drop test for craft with a length $L_H$ of 2.5m up to 6m and single-skin construction. The current method, however, of visual test has the issue where it is difficult to make an objective evaluation of ship body strength. In this study, in order to develop an evaluation system that can make a quantitative evaluation of the drop test of leisure boats, the domestic/foreign regulations on drop test of leisure boats are analyzed and the drop test evaluation system is designed, and the system applicability is reviewed through 5-meter level aluminum ship, and the issues incurred by the state of the ship and the posture while dropping were checked.
