Shandong Haisheng Oceaneering Group is based in Dongying, on the Shandong coast at the mouth of the Yellow River, and supports merchant shipping with underwater inspection, hull integrity testing, tightness verification and non-destructive testing services. Underwater inspection is delivered by trained diver teams supporting in-water surveys covering hull plating, rudder, propeller, sea-chests, anodes and similar appendages, with video documentation prepared for attending class surveyors so afloat examinations can be accepted in lieu of dry-docking when conditions allow. Hull ultrasonic thickness gauging documents remaining steel on plating, frames, longitudinals and tank boundaries, while ultrasonic hatch cover testing and watertight integrity verification address seal performance on bulk carrier, general cargo and multipurpose tonnage. NDT and remote inspection complements the gauging, tightness and in-water work with techniques used to evaluate welds, plating and structural details where cracks, corrosion thinning and weld defects need quantifiable evaluation during periodical, intermediate and special surveys. Service approvals from DNV, ABS, BV and CCS evidence that procedures, equipment and qualified personnel meet the criteria these classification societies apply to the disciplines covered. The technical team coordinates attendance around port stays, anchorages and dry-dockings at Dongying, Qingdao, Yantai and other Shandong and Bohai Bay ports, with reports prepared in formats acceptable to attending surveyors and to owner, manager and crewing offices supporting bulk carrier, tanker and general cargo operators. Working with bulk carriers, tankers, container ships and general cargo tonnage, Shandong Haisheng coordinates equipment logistics, qualified personnel and class liaison so attending teams deliver consolidated underwater, gauging, tightness and NDT scopes within available port time, aligning documentation with the vessel's survey programme and continuous hull and machinery records used by managers and superintendents during periodical, intermediate and special class survey campaigns.
