4.3.1 The design load applied to shipboard fittings
and supporting hull structures should be 1.25 times the breaking strength
of the mooring line provided in accordance with table 1 based on the equipment number
(EN) described in the appendix. The design load should be applied
through the mooring line according to the arrangement shown on the
towing and mooring arrangements plan.
4.3.2 The design load applied to supporting hull
structures for winches, etc. should be 1.25 times the breaking strength
of the mooring line according to 4.3.1 above and, for capstans, 1.25
times the maximum hauling-in force. The design load should be applied
through the mooring line according to the arrangement shown on the
towing and mooring arrangements plan.
4.3.3 The method of application of the design
load to the fittings and supporting hull structure should be taken
into account such that the total load need not be more than twice
the design load specified in 4.3.1, i.e. no more than one turn of
one line.
