Determination of CAS applicability

  2 In order to determine whether the CAS requirements apply to a particular oil tanker, the PSCO should check Form B of the Supplement to the International Oil Pollution Prevention Certificate and, based on information contained therein, determine if the oil tanker complies with regulation 13F or 13G(1)(c). CAS is not required if:

  • .1 the oil tanker complies with either regulation; or

  • .2 the oil tanker is less than 5,000 tons deadweight.

If the oil tanker complies with neither regulation and it is 5,000 tons deadweight and above, then the ship's age should be determined based on the delivery date indicated in the Form B of the Supplement to the International Oil Pollution Prevention Certificate.
