Condition assessment scheme for Category 2 & 3 oil tankers carrying HGO

As advised previously, as from 5 April 2005, MARPOL Regulation 13G(6) will require that all single hull oil tankers (Categories 2 and 3), 15 years of age and over, shall comply with the Condition Assessment Scheme (CAS) concurrent with the first intermediate or renewal survey after that date.

We also wish to remind members that the CAS procedures set up a detailed timeline for the preparation and scheduling of this survey. The time line can cover as much as 12 months or more from the owner's initiation of CAS until the CAS Certificate of Compliance is issued by the flag Administration. If you have to plan for CAS on some of your tankers for the 2nd and 3rd quarter of 2005, please proceed soonest.

The second, but equally important, element to which we wish to draw your attention is the CAS application for Category 2 and 3 tankers to qualify for the application of regulation 13H6(a). We are still seeking some clarification, but it appears that the new 13H 6 (a) (i.e. carriage of Heavy Grade Oils (HGO) with densities between 900 and 945 kg/m3) combined with the new paragraph 5.3.4 of the amended CAS (see MEPC 112 (50)), would require CAS on category 2 and 3 tankers irrespective their age (i.e. younger than 15 years of age).

To that extent, according to the provisions mentioned, if a tanker is carrying HGO with a density between 900 to 945 kg/m3 at 15 degrees C, and the flag Administration extends the 5 April 2005 deadline to a maximum of 25 years of age under regulation 13H(6a), the tanker is to complete CAS concurrent with the first scheduled intermediate or renewal survey after 5 April 2005.

We will revert on this issue but it would be prudent for members to seek clarification with their Flag Administrations.
