Dalian Sun's Ship Safety Technical Service Co., Ltd. is based in Dalian, the major Liaoning Province port on the Liaodong Peninsula that hosts container, crude-oil and bulk terminal complexes alongside long-established ship-repair yards and a strong base of survey-attendance firms serving Bohai Bay and Yellow Sea trading lanes. The firm provides on-board technical attendance covering radio-survey, tightness-testing, thickness-gauging and non-destructive testing scopes for commercial vessels calling Dalian-area berths and the surrounding anchorages used for crew change, bunkering and routine maintenance during ordinary commercial calls. Radio-survey services cover GMDSS annual testing of MF/HF and VHF installations, EPIRBs, SARTs and NAVTEX receivers, with battery load tests, antenna checks and operational verification performed in accordance with SOLAS chapter IV requirements, alongside GMDSS equipment maintenance and AIS annual performance verification on shipborne installations. Tightness scopes cover ultrasonic hatch-cover testing on weather-deck closures of bulk carriers and watertight integrity verification on bulkheads, doors and other compartments where SOLAS tightness requirements apply. Hull ultrasonic thickness measurement campaigns cover shell plating, deck plating, internal structural members and tank boundaries on tonnage subject to periodical, intermediate, special and condition assessment programme surveys, with diminution analysis against original scantlings and class allowable wastage limits. Sun's Ship Safety holds service supplier recognition by the China Classification Society, ClassNK and the Korean Register, allowing reports from radio, tightness, gauging and NDT campaigns to be considered during class survey programmes on commercial tonnage attended at Dalian Xinggang and Dagushan terminals and the Bohai Bay anchorages. Customers include shipowners, ship managers, technical superintendents and port agents arranging routine maintenance attendance during commercial port calls in the Dalian area.
