0000-00-00: IMO PSPC - What is “good”?
The PSPC specifies that the coating in the relevant spaces of a ship that is built under the PSPC regime has to remain in “good” condition during the service life of 15 years.
IMO defines “good” as only minor spot corrosion with no significant corrosion or coating breakdown or detachment.
The “Tank Coatings Conditions Guide” of Lloyd’s Register defines a “good” condition as follows: “Condition with only minor spot rusting affecting not more than 20% of areas under consideration, e.g. on a deck transverse, side transverse, on the total area of platings and stiffeners on the longitudinal structure between these components, etc. “
This guide also contains a wealth of pictorial standards and examples of tank coatings in “good”, “minor” and “poor” condition.
