The basis of the NIR is that vessels will be judged after a set of risk criteria including type, age, class society, flag, company safety history, earlier inspection results, detentions etc. A vessel will then be designated to one of three risk categories. Ships in the high risk category will be subject to inspections every six months or more frequently. Standard risk vessels will face inspections every 10-12 months and low risk vessels every 24-36 months.
Vessels flying the flag of a nation on the black or grey list with two detentions within 36 months may be banned from ports in the Paris MOU region for three months or more. If this happens again, the ban will be for at least twelve months, and a third time may result in a permanent ban.
Paris MOU has also announced a concentrated campaign on life boat launching arrangements during inspections from September 1 and three months on. This is done in a joint effort with the port state organisation Tokyo MOU.
