2.5.1 The required strength of the unit should
be maintained in way of the drilling well, and particular attention
should be given to the transition between fore-and-aft members. The
plating of the well should also be suitably stiffened to prevent damage
when the unit is in transit.
2.5.2 Consideration should be given to the scantlings
necessary to maintain strength in way of large hatches.
2.5.3 The structure in way of components of the
position mooring system such as fairleads and winches should be designed
to withstand the stresses imposed when a mooring line is loaded to
its breaking strength.
