App.C
C 200 Splash zone for floating units
App.C C
201 For fatigue evaluation of floating units, reference to the
draught that is intended to be utilised during condition monitoring,
shall be given as basis for the selection of DFF.
App.C C
202 If significant adjustment in draught of the unit is possible
to provide satisfactory access with respect to inspection, maintenance
and repair, account may be taken of this possibility in the determination
of the DFF. In such cases, a sufficient margin in respect to the
minimum inspection draught should be considered when deciding upon
the appropriate DFF in relation to the criteria for 'Below
splash zone' as opposed to 'Above splash zone'.
Where draught adjustment possibilities exist, a reduced extent of
splash zone may be applicable.
App.C C
203 Requirements related to vertical extent of splash zone are
given in Sec.10 B200.
