Yiulian Dockyard Hong Kong Offers Digital Twin Piping Fabrication Maritime Activity Reports, Inc. May 28, 2026 Source Yiulian Dockyard Hong Kong Yiulian Dockyard Hong Kong is open for business following a major facility upgrade and workforce expansion, with on-site digital twin pipe fabrication adopted in cooperation with Irwin Limited. As the only dockyard in China that accepts vessels alongside laden, the yard targets unplanned dockings for vessels working southern China container ports (Hong Kong, Yantian, Shekou, Nansha) and the Pearl River Delta. General Manager Zhong Ying said: “To enter any other dockyard in China, you would be required to discharge your cargo first. In Hong Kong, you can come alongside laden. If you have an unexpected need to come alongside our dockyard, we can save you the discharging and loading costs.” Hong Kong's high land cost has historically limited the scale of in-yard fabrication capacity, particularly for specialized work like PE lining that requires a large factory footprint. Irwin's ability to create as-built digital twins of pipes in their bolted-up condition brings the Shenzhen-based factory to the yard. “Our customers needed a way to access mainland China's pipe manufacturing capacity, while appreciating that there is still a customs border between Hong Kong and mainland China,” Zhong explains. “By bringing Irwin's AutoMet FAB digital twin process to the yard, we now have the equivalent of an on-site PE-lined pipe factory with a 4–7 day turnaround. Manufacturing happens 30 kilometers away in Shenzhen.” Irwin's field engineers conduct on-vessel surveys using AutoMet FAB equipment, generating a high-precision digital twin of the existing seawater piping. Crucially, AutoMet FAB captures flange miter and tilt, as well as bolt hole rotation errors — the dimensional details that typically cause fit-up problems on older vessels with deformed flange faces or misaligned bolt patterns. The digital twin transfers directly to Irwin's inte
