Zhoushan Yangming Marine Solution Co., Ltd. is a marine technical services contractor based in Zhoushan, Zhejiang Province, serving vessels at the Zhoushan, Ningbo-Zhoushan, Liuheng, Putuo and Daishan anchorages and at major repair yards in the East China Sea cluster. The workshop is configured around hull-survey, tightness and NDT work that supports class-renewal and special surveys without requiring vessels to drydock dedicated to inspection alone. The technical scope covers hull ultrasonic thickness gauging campaigns delivered with class-acceptable digital ultrasonic equipment and reported in standard IACS-format spreadsheets, ultrasonic hatch cover tightness testing on bulk-carrier and general-cargo hatch covers, watertight integrity verification of doors, penetrations and weather-deck closures, and conventional non-destructive examination covering ultrasonic, magnetic particle, dye-penetrant and radiographic testing of welds and structural members during repair-period attendance. Class-accepted underwater hull inspection in lieu of drydocking is coordinated with approved diving partners, supporting in-water surveys recognised by class. YangMing Marine Solution is recognised by ABS, DNV, Korean Register, Lloyd's Register and Bureau Veritas as a service supplier under the relevant in-water survey, thickness-measurement, tightness-testing and NDT categories, allowing inspection reports issued at Zhoushan to be used directly for class surveys and statutory inspections on merchant tonnage flying flags that recognise these IACS members. Field response is coordinated 24/7 across the East China Sea port stations during cargo operations and short voyage-repair stays. Field attendance is scheduled around cargo operations and short port stays so that owners and managers can close hull-renewal, special and intermediate survey items without dedicated drydock time, supporting voyage-by-voyage compliance with class and statutory periodicities.
