Haida United Marine Tech-Services (Beijing) Co., Ltd., trading as HDUM, is a Beijing-based marine technical services firm registered in the Beijing Economic and Technological Development Zone in 2005. The head office is in the Dengshikou Street area of Dongcheng District, with surveyors deployed nationally to support attendances at Chinese shipyards, recycling facilities and operating vessels. The company is recognised as a high-tech enterprise by the Beijing science and technology commission and operates under an ISO 9001:2015 quality management system certified by UKAS and the China Classification Society, with additional recognitions from KR and Lloyd's Register for relevant service scopes.
Inventory of hazardous materials surveys is the company's core specialism. The firm is approved by IACS member classification societies including Lloyd's Register, Bureau Veritas, ClassNK, ABS, CCS, KR and others to develop and maintain IHM Part I, Part II and Part III documentation in accordance with the Hong Kong Convention and the EU Ship Recycling Regulation. Surveyors collect representative samples on board, co-ordinate laboratory analysis through accredited partners and compile the resulting hazardous-materials inventories for newbuild and in-service vessels, with onboard Material Declarations and Supplier Declarations of Conformity gathered from equipment makers.
The wider hazmat survey scope supports ship recycling preparation, sale-and-purchase due diligence and EU-flag compliance for international operators trading to European Union ports. The surveyors are described as having backgrounds as master mariners, chief engineers, deck officers, former shipyard managers and former classification society surveyors, giving the firm experience-led capacity to handle complex IHM projects across tankers, bulk carriers, container ships, gas carriers and specialised vessels worldwide on tight commercial schedules.
