Baohai Marine Services Co., Ltd. is a Qingdao-based Chinese marine inspection company supporting shipowners, managers, and shipyards along the Shandong coast and across northern China. The team operates from Huangdao District and attends vessels at Qingdao, Yantai, Weihai, Rizhao, Tianjin, and Dalian, as well as further afield when asked to deploy inspectors to client yards or anchorages. Survey activity is documented through digital reporting that interfaces with the major classification society review systems.
Core technical work covers hull ultrasonic thickness gauging during intermediate, special, and class renewal surveys; ultrasonic hatch cover tightness testing for bulk carriers and general cargo vessels; and watertight integrity verification for hatches, doors, manholes, and other closing appliances. Inspectors deliver non-destructive testing services that include ultrasonic, magnetic particle, dye penetrant, and visual examination on structural members, welds, and machinery components, with documentation tailored to shipboard newbuild, repair, and continuous-survey applications. Inspection campaigns are scheduled to fit within commercial trading windows.
The Baohai team is recognised by a broad set of classification societies, including the American Bureau of Shipping, Bureau Veritas, China Classification Society, ClassNK, Korean Register of Shipping, Lloyd's Register, and RINA, which allows the firm to be engaged on tonnage operating under most of the world's principal flag administrations. The Korean Register of Shipping has approved the company as a firm engaged in thickness measurement on ships and mobile offshore units and as a firm providing non-destructive testing services on ship and offshore structures and components. This multi-class qualification framework supports owners of mixed fleets who need a single Chinese service partner for their northern China port calls.
