Other nodes such as shape based buoyancy, tanks and contact meshes need to be converted before they can be exported. These nodes can be exported directly to orcaflex. programs ( Flexcom, Orcaflex, Deeplines ) in the next design phase. Strong background on global analysis of different configurations (free hanging catenary, lazy wave, FSHR etc.). +15 years experience on subsea umbilical structural calculation, technical specification and qualification processes. (1) The wetted proportion is multiplied with each of the hydrodynamic inputs, so that they are applicable to only the submerged portion of the buoy. The maximum tension calculated from the catenary analysis needs to be less than. Subsea umbilical specialist within Petrobras’ Guidelines, Compliance, Qualification and Technology group. Examples are Axis, Bodies, Linear Hydrostatics, Beams, cables (exluding cable-to-circle contact) and Wave Interaction. 16 variation in depth of the submerged center of volume (dCOV), and the depth of the center of volume (dCOV) (OrcaFlex 2009): 2 (1W) COV COV h d d.
Some nodes have a 1-on-1 counterpart in orcaflex. This means orcaflex itself is not needed for the export. When orcaflex is presented with a model that is already in static equilibrium the program will accept that.ĭAVE can export directly to orcaflex. It may therefore be a real time-saver to solve statics in DAVE and than export the solved model to orcaflex. It is easy to find a model that DAVE solves correctly but does not converge or converges to an unwanted static equilibrium in orcaflex. In this section we list tests that confirm that DAVE delivers the outcome that is to be expected based on either an analytical solution, common sense or other software. However it is more geared towards speed than stability. DAVE is a general framework which can be used for many purposes. These need to be linearized before exporting. Expection are the nonlinear fluid nodes (tanks, buoyancy shapes) that DAVE has. Orcaflex orcaflex is a well known dynamic analysis package offering myriad options.Īs many concepts in DAVE and Orcaflex are identical it is relatively straight forward to export a DAVE model to orcaflex.
