                     The minimum double side width, Wds, in m, is to be taken as the lesser
                        of:
                     
                     
                     
                     
                     
                     
                     
                     
                     Wds = 2.0

                     Double side skin means a configuration where each ship side is constructed by the side
                        shell and a longitudinal bulkhead connecting the double bottom and the deck. Hopper side
                        tanks and topside tanks may, where fitted, be integral parts of the double side skin
                        configuration. 
                     
                     
                     
                     
                     The minimum double side width, Wds, is not to be less than 1 m measured
                        perpendicular to the side shell.

                     The minimum clearance is defined as the shortest distance measured between assumed lines
                        connecting the inner surfaces of the stiffeners on the inner and outer hulls. 
                     
                     
                     
                     
                     3.2.2 Minimum clearance dimensions 
                     
                     
                     
                     
                     The minimum clearance between the inner surfaces of the stiffeners inside the
                        double side is not to be less than:
                     
                     
                     
                     
                        - 600 mm when the inner and/or the outer hulls are transversely framed, 
 
                        - 800 mm when the inner and the outer hulls are longitudinally framed.
 
                     
                     
                     
                     
                     Outside the parallel part of the cargo hold, the clearance may be reduced but is not to
                        be less than 600 mm.
