3.1 An Administration which receives a request
for approval of an alternative tanker design for the purpose of complying
with regulation 13F, should
first evaluate the proposed design and satisfy itself that the design
complies with these Guidelines and other applicable regulations of
MARPOL Annex I. That Administration should then submit the proposal
and the supporting documentation, together with its own evaluation
report, to the Organization for evaluation and approval of the design
concept by the MEPC as an alternative to the requirements of regulation
13F(3). Only design concepts which have been approved in principle
by the MEPC are allowed for the construction of tankers to which regulation
13F(5) applies.
3.2 The submission to the Administration and the
Organization should at least include the following items:
-
.1 detailed specification of the alternative design
concept;
-
.2 drawings showing the basic design of the tank
system and, where necessary, of the entire ship;
-
.3 study of the oil outflow performance as outlined
in paragraphs 1.3 to 1.5;
-
.4 risk analysis as outlined in paragraph 1.7;
-
.5 details of the calculation procedure or computer
program used for the probabilistic oil outflow analysis to satisfy
the Administration that the calculation procedure used gives satisfactory
results. For verification of the computer program see paragraph 6.2.
Any additional information may be required to be submitted
if deemed necessary.
3.3 In addition to the approval procedure for
the design concept specified in paragraphs 3.1 and 3.2 above, the
final shipyard design should be approved by the Flag State Administration
for compliance with these Guidelines and all other applicable regulations
MARPOL Annex I. This should include survivability considerations as
referred to in paragraph 5.1.5.10.
3.4 Any approved design concept will require reconsideration
if the Guidelines have been amended.
