Instead, please define the wind drag force\/moment coefficients for all the possible directions from -180 degree to 180 degree.&nbsp; If you really want to define the external surfaces of supper structure, it is OK, but please remove all the internal surfaces, especially between the upper deck and supper structures.&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;(2) If you want model the rigid pipeline by a mooring line, the boundary condition between mooring and laying barge\/roller on the stinger cannot be modelled properly by Aqwa, as the ball\/socket joint condition is applied at the fairlead point of the cable in Aqwa.&nbsp;&lt;\/p&gt;&lt;p class=&#8221;MsoNormal&#8221;&gt;(3) Not sure what you mean &#8220;the rigid pipeline&#8221;.
