Zhoushan Sunrise Marine Service Co., Ltd. is based in Zhoushan, an island-based Zhejiang Province city that forms the eastern half of the combined Ningbo-Zhoushan port complex, the world's busiest port by cargo throughput, with major crude, bulk, container and ship-repair facilities spread across the Cezi, Liuheng, Daxie and surrounding islands of the archipelago. The firm specialises in inspection scopes that support classification society survey requirements and routine maintenance attendance during vessel calls in the Ningbo-Zhoushan port area and at the surrounding East China Sea anchorages used for crew change, bunkering and stores. Ultrasonic hatch-cover testing covers weather-deck closures on bulk carriers and general cargo ships where leak-tightness affects cargo condition and stability, and watertight integrity verification is offered on bulkheads, doors and other compartments where SOLAS tightness requirements apply. Hull ultrasonic thickness measurement campaigns cover shell plating, deck plating, internal structural members, frames, longitudinals 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. Non-destructive testing scope covers ultrasonic, magnetic-particle, dye-penetrant and visual examination of welds and structural members performed by qualified Level II technicians. Sunrise Marine holds service supplier recognition by ABS, Bureau Veritas and Lloyd's Register, allowing reports from tightness, thickness and NDT campaigns to be considered during class survey programmes on commercial tonnage attended at the Ningbo-Zhoushan terminals and surrounding archipelago anchorages used by ocean-going vessels. Field teams attend at berth, anchorage and in dry-dock with calibrated equipment, supporting owners and managers on bulk carriers, tankers and container ships.
