About HEWEN
Sailing since 2001, dedicated to providing outstanding marine engineering services
Established in 2001, HEWEN Engineering Co. is the subsidiary company of SanYang shipyard. For the past 20 years, it has been mainly providing shipyards and shipowners in the one shop service, including docking repair & maintenance with electricians, painting & aluminum welding.
In 2020, we moved our business into another page which is to decide to represent navigation, automation, local service partner, project manager localization, deck machinery, etc. which brings up different angle of business. Hewen is different with other trading, we are more focusing on technical service and consider more localization to fulfill the trend to meet customer needs.
