Hong Kong shipowner · emergency seawater-pipe replacement
Project Background
While a Hong Kong owner's vessel was in port, engine-room staff found multiple corrosion perforations in the seawater line, with leakage already threatening nearby electrical equipment. The owner urgently approached local suppliers for replacement pipe, only to hit a long-overlooked industry gap — Hong Kong has no pipe-lining facility at all, no PE-lining capability and no galvanising. The traditional fallback was bare black steel with no corrosion protection, lasting only one to two years.
Challenges & Requirements
The owner needed corrosion-protected seawater pipe in the shortest possible time, but faced two obstacles: first, no lining capacity in Hong Kong; second, Chinese customs rules barring foreign vessels' used pipe from entering the mainland for physical copying. So the pipe could be neither made locally nor copied from the old pipe in Shenzhen. With a tight schedule, the owner required supply within a week.
The core difficulty: no local lining capacity + no cross-border movement of the old pipe → the traditional supply chain breaks down completely
The Irwin Solution
Irwin's solution sidestepped every obstacle: technicians digitally surveyed the pipe at the Hong Kong quay with Automet, capturing dimensions only — no physical movement. With the data back in Shenzhen, the workshop prefabricated and PE-lined to the digital model. The finished spools cleared customs through the normal export process and reached the Hong Kong quay within 6 to 8 days via the Shenzhen–Hong Kong land crossing — fully compliant, and needing no local lining facility.
Process
Results
From survey to delivery in just 6 to 8 days, fully meeting the owner's urgent schedule
The spools fitted first time, with no on-site adjustment
Overcame Hong Kong's lack of a local lining facility, making high-quality corrosion-protected pipe possible
The owner no longer has to accept a low-quality stopgap, raising the maintenance standard significantly
✅ 6–8 day rapid delivery — breaking geographic and regulatory limits to meet an urgent schedule.
✅ 100% precise fit — the digital twin ensures zero interface error.
✅ Overcoming Hong Kong's lining-capacity gap — opening a new route for the local ship-repair industry.
✅ A permanent end to black steel — high-quality corrosion-protected pipe becomes the norm.
Client Value
This project opened a wholly new pipe-supply route for Hong Kong owners. For years the local ship-repair industry, lacking a lining sector, had to accept low-standard or high-cost options. Irwin's digital-survey-plus-Shenzhen-prefabrication model resolves that structural pain point at the root — needing neither a local lining facility nor any cross-border movement of the old pipe, delivering high-quality prefabricated spools to international standards from digital data alone.
