  1. Interface & Results Automation Other VIV Toolbox Environment Vessels Lines Buoys & Winches Introduction

  2. Environment • Current speed & direction vs. simulation time •  and current speed vs. horiz. position in fluid • More flexible JONSWAP & ISSC settings • Choice of 3 kinematic stretching methods • New wave type: User Specified Components • More results available: Wind direction, Sea vel & accel magnitudes, Current speed & direction, Hydrostatic pressure

  3. Lines • Line Ends Form renamed All Lines Form • Specification of Line segmentation improved • Section cumulative length and no. of segments • Improved reporting of Line Clearance results • Line Expansion Factor added • Clumps aligned with Line axes • New Step 1 statics method (User Specified) • Seabed reaction force results variable added

  4. Vessels • Multiple applied loads can be set • Applied loads can be set vs. simulation time or by an externally called function • All draught dependent Vessel Type variables can now be set as a function of draught • New Report Vessel Response facility • Wave drift forces and moments available as results

  5. Buoys & Winches • Wave force & moment RAOs for Buoys • Multiple applied loads can be set • Applied loads can be set vs. simulation time or by an externally called function • Wing orientation can be set vs. simulation time or by an externally called function • Buoy properties available via pop-up menu • Winch control extended to vary with simulation time or by an externally called function

  6. Interface & Results • Model Browser ‘groups’ • Multiple file replay • Locate Object facility • New Graph menu • Instantaneous Value results period • Rainflow half-cycle graphs now available • Delete unused Types and Variable Data Sources

  7. Automation • New Batch Script commands • Results Spreadsheet can now be used with the Statics-only OrcaFlex licence • Results Spreadsheet can now output pipe stress component results

  8. Other • Results available for drag chains • Current direction shown in modal analysis view • Better fatigue analysis reporting • New Extend Simulation facility • New dynamic ramping function

  9. VIV Toolbox • Now split into Freq. and Time domain modules • Ramping from Morison drag to vortex force • Automatic perturbation of time domain models • User defined vortex force Factors • Sarpkaya vortex tracking model runs twice as fast • Disable VIV modelling for parts of lines • New experimental vortex tracking model • Inline and transverse force results available • Detailed control of time domain VIV drawing
