The Oil Companies International Marine Forum (OCIMF) is to extend access to its reports to non-members.
The voluntary association of oil companies said the Tanker Management and Self Assessment (TMSA) data would be available from 14 January.
"This major change will mean more information is available to more users, which will help improve overall safety and marine assurance," it said.
Non-members who are registered as Ship Inspection Report Programme (SIRE) recipients will be able to see the reports, provided vessel operators agree.
