Text of paragraph 2.10 of the Guidelines for emergency
towing arrangements on tankers (resolution MSC.35(63)):
Designs of emergency towing arrangements in accordance with
these Guidelines should be prototype tested to the satisfaction of
the Administration".
Towing arrangements may be (1) a packaged self contained
unit, or (2) a unit comprised of individually tested components assembled
on board the vessel.
Both arrangements should meet the specified strength requirements
and undergo a deployment test on board the vessel as required by resolution MSC.35(63).
Fixed gear such as strong points, fairleads, foundations
and associated vessel supporting structure are to be demonstrated
as adequate for the loads imposed by means of a submitted engineering
analysis or calculations. If the structural configuration is of a
particularly complex or novel nature, such that its load bearing adequacy
cannot be satisfactorily determined by engineering analysis, suitable
proof test will be required.
Articles of loose gear such as chains, towing pennants and
associated end fittings, and shackles or other connecting links should
be tested to the requirements of the Classification Society concerned.
Where a manufacturer requests a certificate of type approval
for a complete self-contained arrangement, one assembled unit is additionally
to undergo a test to 2 x SWL.
