Ship/vessel vetting is the process by which a charterer determines whether a vessel is suitable to be chartered, based on the information available to it. Ports, terminals, insurers and other maritime industry operators also vet ships to identify and manage risks, and many shipowners and ship managers use ship vetting services to monitor information about their own vessels.

Unlike certification or classification, vetting is a private, voluntary system operators may opt to use to help them choose a particular vessel from among all of the certified vessels available, and to manage their risks.

Vetting in its current form first appeared in 1993, when the Ship Inspection Report (SIRE) database was created for use by oil companies. For each voyage, the vetting department assesses the vessel to be used, relying in particular on inspection results.

[edit] Oil tanker vetting

The results of inspections carried out by oil companies, who are members of the OCIMF (Oil Companies International Marine Forum), are shared via the joint SIRE database. Oil majors perform inspections according to a standard report format developed by the OCIMF. These reports are available to all OCIMF members via the SIRE database, which provides each company’s vetting department with the information it needs to apply its own internal criteria without having to inspect each vessel itself. Tanker vetting inspections are usually carried out during commercial unloading operations, with the prior agreement of the shipowner and management company, the only organizations authorized to allow third parties onboard.

Vetting inspections do not include a survey of the vessel’s structural elements, which is the responsibility of the classification society and the shipowner as part of the vessel’s regular maintenance and of the process of ensuring that it complies with applicable rules and regulations. In any case, it would be technically impossible for a vetting department to carry out such a structural survey.

Vetting inspections also give the company access to confidential documents relating to the vessel’s maintenance and classification, which can only be consulted by third parties onboard.

Na podstawie rozporządzenia Ministra Infrastruktury z 2004 w polsce takiej obowiązkowej inspekcji podlegają wszystkie tankowce starsze niż 10 lat.

Chyba, że chodziło np. o platformy wiertnicze, a niekoniecznie statki przeed wejściem do portu to inspekcja bezpieczeństwa wg standardów członków OCIMF. Ciągle jesteśmy w zakresie procedur dotyczących tankowców/gazowców.
