Innovating for a Sustainable Water Future
Underwater construction, hydraulic engineering and drainage innovation in Hong Kong since 1999.
Charting a New Course for Water Solutions
Yan & Partners Engineering Co., Ltd. was established in Hong Kong in 1999. We design, build and maintain works in and around water: underwater construction, hydraulic engineering, irrigation and drainage. Field problems have pushed us to invent our own tools and systems, including the underwater welding handle now standard across Hong Kong's diving industry, and the patented Multipurpose Drain Pipe (MDP).
