CAS is a mandatory statutory survey scheme that Category 2 and Category 3 (non-double hull) oil tankers must satisfactorily complete (with no outstanding recommendations) by 15 years of age or by the first intermediate or renewal survey due after 5 April 2005, whichever occurs later, in order to trade to their respective phase out date as per MARPOL 13G, which was accelerated by resolution MEPC.111(50) which entered into force on 5 April 2005.
CAS is required to be conducted in conjunction with, the mandatory Enhanced Survey Program (ESP) and builds upon ESP ACSA by requiring additional thickness measurements and close-up surveys. Relative to ESP, CAS is unique in two respects:
- CAS contains very specific responsibilities and deadlines for planning the survey, which must begin 8 months in advance of the survey’s commencement; and
- The flag Administration must review/monitor the survey and reporting process and issue the five-year full term (CAS Statement of Compliance).
