Abstract

In accordance with the regulations announced at the 83rd session of the Marine Environment Protection Committee (MEPC 83) of the International Maritime Organization (IMO) in 2025, and in line with the global transition toward environmentally friendly ships, the adoption of composite materials and advanced manufacturing technologies has been accelerating in the shipbuilding and offshore industry. The establishment of a composite manufacturing technology hub in Ulsan, Korea, and the introduction of hybrid thermoplastic composite pipe (HTCP) regulations by Det Norske Veritas Germanischer Lloyd (DNV) in Norway reflect these industrial trends. For marine pipes that demand both lightweight properties and high durability, the application of composite materials has become essential. In particular, small-to-medium pipes used in ships are widely applied across numerous onboard systems, resulting in high usage rates and frequent replacement or maintenance, which makes the choice of material and manufacturing method highly influential. This study focuses on small-to-medium bore marine pipes, analyzing current International Classification Society regulations, including DNV-ST-C501, to identify key considerations in the design of 3D-printed composite pipes and to propose a six-step design procedure reflecting these findings.


국제해사기구(International Maritime Organization, IMO)의 2025년 MEPC 83차 회의에서 발표된 규제와 글로벌 친환경 선박 전환 추세에 따라, 조선해양산업에서는 경량화 및 내구성 확보를 위한 복합재료 및 첨단 제조기술의 도입이 가속화되고 있다. 울산시의 복합재료 제조기술 허브 구축과 노르웨이 선급(Det Norske Veritas Germanischer Lloyd, DNV)의 하이브리드 열가소성 복합재료 유연 파이프(Hybrid Thermoplastic Composite Pipe, HTCP) 규정 발표는 이러한 산업 변화를 반영한다. 경량화와 높은 내구성을 요구하는 조선해양 파이프에 대해 3D 프린팅 복합재료 적용은 필수적이며, 특히 선박의 중소구경 파이프는 선내 다수 계통에 광범위하게 적용되어 사용량과 교체·유지보수 빈도가 높아, 재료·제조 선택이 미치는 영향이 크다. 본 연구는 중소구경 선박 파이프를 대상으로 현행 DNV-ST-C501 등 국제 선급 규정을 분석하여, 3D 프린팅 복합재료 파이프 설계 시 주요 고려사항을 도출하고 이를 반영한 6단계 설계 절차를 제안하였다.
