Ship Life-Cycle and Class Surveys

During the construction process, PANAMA MARITIME DOCUMENTATION SERVICES INC. (PMDS)surveyors regularly inspect materials at shipyards, supervise welding procedures, review and witness welder performance qualification tests, perform on-site surveys and monitor fabrication during all stages of the construction, witness destructive testing, survey the building and installation on board at the shipyard of all essential machinery, and attends final dock and sea trials.

Survey after Construction

Maintenance of Class PMDS Classification is assured by the system of periodic surveys to determine continued compliance with its Rules. These include various surveys of hull and machinery on a continuing basis.
