Class notation for Oil Pollution Prevention for Fuel oil tanks.
To ensure compliance with requirements applicable to a vessel arranged and equipped to minimize the risk of fuel oil pollution before IMO mandatory requirements for Fuel oil tank protection enter into force.
The notation includes additional environmental protection of fuel oil tanks according to requirements that will come into force later in MARPOL Annex I, Regulation 12A, and the requirement of an additional separation arrangement for bilge water systems in Engine rooms.
This class notation is assigned on the basis of survey reports verifying compliance with the rules.
