.... The cr~t~cal load case was that of full flood~ng of the upper and lower columns at one corner of the vessel for the reserve buoyancy requ~rement (sect1on 9.4). 5.2 Selection of Hull Configuration The next task was to select the number of columns for the STAPLA vessel. The number of columns was kept...

... of equipment subsea or on the topside layout A number of factors have been considered in the selection of tower dimensions and layout: Dimensions and size of buoyancy tank Location of buoyancy tank Number of main legs Type of bracing system Slenderness of tower Type of mooring system The number of legs...

... though some strong artificial damping had been introduced. The set-down in regular waves was reasonably well predicted by considering the submerged volume of the test cylinder. The results were analyzed by a force model of a Morison type, but with a simple buoyancy term added. The force coefficients were...
