Guangzhou Hairun Shipping Technical Co., Ltd. is a limited liability company holding independent legal person status under Chinese commercial law. The business traces its origin to a Guangzhou branch office of Tianjin Hairun Marine Technical Co., Ltd. that was opened in 2008 to extend the parent's coverage into the Pearl River Delta, and the southern unit was subsequently reorganised as a standalone Guangzhou-registered entity. Core activity centres on marine electronics installation, integration and after-sales technical service for commercial shipping, with engineers handling navigation equipment, radio communication kit, satellite television antennas and shipboard local area network infrastructure on vessels calling at Guangzhou, Huangpu and Nansha. The Guangzhou Hairun service catalogue covers annual functional checks on Global Maritime Distress and Safety System sets, including survey of medium-frequency, high-frequency and very-high-frequency radios, Inmarsat satellite terminals, EPIRBs and SARTs, alongside annual inspection of Automatic Identification System transponders. Technicians also provide remote inspection support and non-destructive testing services tied to communication and navigation equipment surveys. Recognition by the China Classification Society lists the firm among the authorised service stations for GMDSS radio surveys and AIS annual checks on CCS-classed tonnage. A related entity, Hongkong Hairun Shipping Technical Co., Limited, appears in the Hong Kong company register, indicating cross-border arrangements covering vessels managed from both sides of the border.
