OVID Inspections 

Survey Association have a number of OVID inspectors who are accredited by the Oil Companies International Forum (OCIMF) to perform OVID Inspections.  Offshore Vessel Inspection Database (OVID) is an inspection protocol that will allow project and marine assurance teams to assess the safety and environment performance of a vessel and its operators in a more effective and uniform manner.

We also offer service for pre-OVID inspections of the offshore vessels before their employment for end-user.

OVID may be scaled to include other inspection/audit types; inclusion of these will be subject to the oil company's needs.  Inspections are tailored to the operations that the commissioning company is interested in.
