Shandong Lion Testing Technology Service is based in Yantai, on the northern coast of Shandong province, and focuses on specialised testing services for the merchant shipping sector, with particular emphasis on ballast water treatment system support and underwater inspection. BWTS commissioning and service work supports compliance with the Ballast Water Management Convention, covering commissioning testing, sampling and routine technical support across a range of treatment systems used on bulk carriers, tankers and other tonnage. The team supports owners and managers in resolving operational and equipment issues encountered during BWTS commissioning, intermediate and renewal surveys. Underwater inspection is delivered by trained diver teams supporting in-water surveys covering hull plating, rudder, propeller, sea-chests 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. Service approvals from ABS, BV, DNV and LR evidence that procedures, equipment and qualified personnel meet the criteria these classification societies apply to BWTS and in-water survey contractors. Reports are prepared in formats acceptable to attending surveyors and to owner, manager and superintendent departments. The technical team coordinates attendance around port stays, anchorages and dry-dockings at Yantai, Qingdao and other Shandong and Bohai Bay ports, with mobilisation possible to other Chinese coastal ports when survey or commissioning schedules require. The focused scope supports operators looking for specialised BWTS and diving support during routine and unscheduled attendances on merchant tonnage. Working with bulk carriers, tankers, container ships and general cargo tonnage trading through Yantai, Qingdao and adjacent Shandong and Bohai Bay ports, Shandong Lion Testing coordinates equipment logistics, qualified personnel and class liaison so attending teams deliver consolidated BWTS and underwater scopes within available port time, aligning documentation with the vessel's ballast water management plan and continuous hull records.
