Hong Kong’s Yiulian Dockyard has officially reopened following a significant modernisation programme and workforce expansion, with management positioning the facility as one of the most operationally flexible ship repair hubs in Asia.
Operated by China Merchants Shipbuilding Industry, the Tsing Yi-based yard is now highlighting a capability that sets it apart within mainland China: it is the only dockyard in the country permitted to receive vessels alongside while still fully laden with cargo.
This operational flexibility provides a major advantage for shipowners facing emergency repairs or unplanned maintenance, particularly in the busy maritime corridors of southern China. In contrast to other yards, where cargo must first be discharged, Yiulian allows vessels to proceed directly to repair work without unloading.
“To enter any other dockyard in China, you would be required to discharge your cargo first,” said general manager Zhong Ying. “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.”
The capability is especially relevant for vessels calling at major regional ports such as Hong Kong, Yantian, Shekou and Nansha, where unscheduled repairs can otherwise result in costly delays linked to cargo handling and port congestion.
Alongside the physical upgrade, the yard has also introduced a new digital twin pipe fabrication system developed in partnership with marine engineering specialist Irwin Limited. The system connects Yiulian’s repair operations with manufacturing facilities located in Shenzhen, helping overcome Hong Kong’s long-standing space constraints for large-scale fabrication work.
High land and operational costs in Hong Kong have traditionally limited the ability of local yards to carry out complex fabrication projects, particularly for specialised components such as polyethylene-lined seawater piping systems. The integration of Irwin’s AutoMet FAB digital twin technology now allows precise onboard laser scanning to be conducted in Hong Kong, while replacement pipe sections are manufactured at a dedicated facility approximately 30 km away in Shenzhen.
According to the companies, this approach significantly reduces turnaround times and minimises vessel off-hire periods.
“What Yiulian Hong Kong has done is bring this capability to the yard’s doorstep,” said Zhong Ying. “This is an example of how we are working with vessel owners to reduce off-hire time and streamline their dockings.”
The system captures highly detailed measurements of onboard piping infrastructure, including flange alignment and bolt-hole rotation errors commonly found on ageing vessels. Replacement pipe spools are then fabricated offsite and delivered ready for installation, eliminating the need for onboard hot work or re-cutting.
A recent application of the system involved a 20-year-old panamax containership, where 38 polyethylene-lined seawater spools were installed with what was described as a 100% first-time fit rate.
Founded in 1964, Yiulian Dockyard remains Hong Kong’s largest ship repair facility, servicing more than 130 vessels annually across tanker, gas carrier, container, cruise and dry bulk segments.
