2.4 Special considerations for surface units

  2.4.1 The required strength of the unit should be maintained in way of the drilling well, and particular attention should be given to the transition of fore and aft members. The plating of the well should also be suitably stiffened to prevent damage during transit modes of operation.

  2.4.2 Consideration should be given to the scantlings in way of large hatches to maintain strength.

  2.4.3 The structure in way of components for 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.
