1.1 The Condition Assessment Scheme (CAS) is intended
to complement the requirements of Annex B of the Guidelines on the
enhanced programme of inspections during surveys of bulk carriers
and oil tankers (hereinafter called Enhanced Survey Programme), adopted
by the Assembly of the International Maritime Organization by resolution A.744(18), as amended. The CAS is to verify
that the structural condition of single hull oil tankers at the time
of survey is acceptable and, provided subsequent periodical surveys
are satisfactorily completed and effective maintenance is carried
out by the ship’s operator, will continue to be acceptable for
a continued period of operation, as indicated in the Statement of
Compliance, or Interim Statement of Compliance, as applicable.
1.2 The requirements of the CAS include enhanced
and transparent verification of the reported structural condition
and of the ship and verification that the documentary and survey procedures
have been properly carried out and completed.
1.3 The Scheme requires that compliance with the
CAS is assessed during the Enhanced Survey Programme of Inspections
concurrent with intermediate or renewal surveys currently required
by resolution A.744(18), as amended.
1.4 The CAS does not specify structural standards
in excess of the provisions of other International Maritime Organization
conventions, codes and recommendations.
1.5 The CAS has been developed on the basis of
the requirements of resolution A.744(18),
as amended, which were knownfootnote at
the time of the adoption of the CAS. It is the intention to update
the CAS as and when the need arises following amendments to resolution A.744(18), as amended.
