1 The Maritime Safety Committee, at its
seventy-second session (17 to 26 May 2000), having considered a recommendation
made by the Sub-Committee on Ship Design and Equipment (DE) at its forty-second
session, agreed that IACS Unified Interpretation regarding the prototype test
provided in the Guidelines for emergency towing arrangements on tankers
(resolution MSC.35(63)) should be disseminated among Administrations in order to
ensure uniformity in the application of the said Guidelines under SOLAS
regulation II-1/3-4 - Emergency towing arrangements on tankers.
2 Member Governments are recommended to apply the
attached IACS Unified Interpretation when implementing SOLAS regulation
II-1/3-4, as appropriate.
Annex IACS Unified interpretation - SC 113 Emergency Towing Arrangements on Tankers - Prototype Test
Text of paragraph 2.10 of the
Guidelines for emergency towing arrangements on tankers (resolution
"2.10 Prototype test
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
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
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.
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.
