Spectral Fatigue - 1

Part 8 -Spectral Fatigue Preparation

1) Under “Training Project”, create “Spectral Fatigue” subdirectory 2) Under “Spectral Fatigue”, Create “Foundation SE”, “Modes” and “Fatigue”

subdirectories. 3) Copy SACINP.STA model file, SEAINP.STA Seastate file and PSIINP.DAT soil data

from “\Spectral Earthquake\Static SE” directory to “Foundation SE” directory. 4) Copy SEAINP.DYN from “\Spectral Earthquake\Modes” directory to “Modes” directory

Creating foundation superelement under “Foundation SE” directory,

1) Modifying Model file SACINP.STA for creating foundation superelement suitable for wave response analysis

Live weight factor in weight combination MASS shall be modified from 0.75 to 1.0.

2) Modifying Seastate file SEAINP.STA for create foundation superelement suitable for

wave response analysis

Delete load conditions GRVX and GRVY; Add two new load conditions named as X000 and Y090, wave loads will be generated for 1.5 m wave height at 4.42 sec wave period for both 000 and 090 directions respectively. Stream function will be used for calculating wave force in 18 steps, maximum base shear will be selected for critical position. Weight selection lines INCWGT used to select weight groups ANOD and WKWY for possible wave forces. Delete load combination EQKS. Combine load combinations SUPX and SUPY with X000 and Y090 correspondingly. Modify LCSEL line to only include SUPX and SUPY load combinations.

3) Delete Title line of PSIINP.DAT, otherwise it will has problem in following fatigue analysis

4) Creating run file to generate foundation superelement using SUPX and SUPY.

In “Analyis Options” > “Foundation” part, select “Create foundation superelement” and input SUPX and SUPY to 1st X and 1st Y load cases respectively, “Max load and deflections” will be used for pile head load/deflection option. No “Element Check” and “Postvue” database needed for this analysis. Run analysis.

Wave Response analysis under “Fatigue” directory,

1) Create Seastate input file SEAINP.000, SEAINP.045 and SEAINP.090 for Transfer function generation

Copy SEAINP.DYN Seastate file from “Modes” directory and rename to SEAINP.000. Input DYN analysis option in col.56-58 for generating loading and hydrodynamic modeling for dynamics. Input title line as “000 DIRECTION TRANSFER FUNCTION”. Four load cases 1 through 4 will be added, each load case contain one line of GNTRF transfer function generation line. For fist load case in 000 direction: 6 waves in 18 steps will be generated using wave steepness 0.05; beginning wave period 10 seconds and period step size 1.00 seconds; transfer function loading will be generated for each wave position and AIRY wave theory will be selected. Base shear and overturning moment will be plotted

For second load case in 000 direction, 6 waves with starting period = 4.75 secs and period step size = 0.25 secs. For third load case in 000 direction, 11 waves with starting period = 3.40 secs and period step size = 0.10 secs.

Launch and Post Launch - 1

Part 16 - Launch and Post Launch Preparation

1) Under “Training Project”, create “Launch” subdirectory 2) Copy SACINP.DAT model file from “\Tow\Tow Inertia” directory to “Launch”

directory. Create Launch input file LNHINP.DAT for jacket launch analysis

For Launch options, use MN unit for both input and output; Set “Accel Velocity Disp Plot Type” as NPF for neutral picture file. Input water depth 79.50 m and seawater density as 1.025 MT/m^3. A launch time control TIME line is need. Set stop time to 625.0 seconds, set output time intervals to 10.0, 5.0, 1.0, 1.0 and 5.0 corresponding to phase 1 to 5. Minimum launch time step = 1.0E-8 second and error control parameter =1.0. Jacket Orientation JACKET line will be added to define jacket position relative to barge. Joint 401L, 405L and 101L will be input as 1st, 2nd and 3rd joints. Distance from barge front to 1st joint = 84.0 m; Length of Launch Framing = 82.0 m; Density of construction material and added load = 7.85 MT/m^3 Barge description will be input on BARGE1 line: Height of barge = 7.50 m; Width of barge = 18.50 m; Bottom Length of barge = 75.0 m; Forward Extension = 5.0 m; Aft Extension =7.50 m; Forward initial draft = 2.25 m; Aft initial draft = 4.50 m; Number of side and bottom increments = 20 Additional Barge description will be input on BARGE2 line: Skid height = 1.50 m; Rocker Pin Location = 84.0 m; Rocker arm depth = 2.75 m; Winch speed = 0.1 m/sec; Both drag and added mass coefficients = 1.0 Weight groups ANOD, LPAD and WKWY will be selected using INCWGT line. Friction coefficients will be input using FRICT line to define: Static friction coefficient = 0.1 Dynamic friction coefficient = 0.05 for speed from 0.0 t 10.0 m/sec


Member group CAN will be deleted from launch analysis using GRPDEL line. A geometry plot PLTGM line added to select “Plot Type” = Full and using STEP for plot intervals. Initial jacket on barge will be plotted. The launch input file generated shall looks like following: ------------------------------------------------------------------------------------------------------------- LAUNCH EXAMPLE LAUNCH MNMN PT PF 79.50 1.025 TIME 625.00 10.0 5.0 1.0 1.0 5.0 1.0E-8 1.0 JACKET 401L405L101L 84.0 82.0+Z 7.85 7.85 BARGE BARGE1 7.50 18.50 75.00 5.0 7.50 2.25 4.50 20.0 20.0 BARGE2 1.50 84.0 2.75 0.10 1.0 1.0 INCWGT ANODLPADWKWY FRICT FRICT 0.1 0.00 0.05 10.00 0.05 GRPDEL CAN PLTGM FLJB 1 END

Flotation and Upending - 1

Part 17 - Flotation and Upending

Preparation

1) Under “Training Project”, create “Flotation” subdirectory 2) Copy SACINP.DAT model file from “Launch” directory to “Flotation” directory.

Modifying model for flotation analysis

Launch model can be directly used for flotation analysis without modification.

Creating flotation input FLTINP.DAT for flotation analysis Flotation options:

MN units will be selected for both input and output; Water depth = 79.50 m with water weight density = 1.025 MT/m^3; Maximum number of iterations = 500 with weight iteration tolerance = 0.001 and moment iteration tolerance = 0.01; Upending type = SHJF for single hook with jacket initially floating.

A jacket orientation line JCKO is required for locate the initial position of jacket: Material weight density = 7.849 MT/m^3 with 1.0 weight contingency factor;

Joint 103L, 107L and 503L will be input to Jacket Orientation joint #1 to #3 to determine jacket initial flotation position; Added load density = 7.849 MT/m^3.

Plot neutral picture file parameters PLOTH line needed for plotting, Plot destination = FILE only; All steps will be plotted for pitch views; A summary report line PLTRQ needed to request various kinds of reports, Hook loads, Sling loads and Mudline clearances will be reported.

Member group CAN will be deleted from flotation analysis using GRPDEL line. Weight groups ANOD, LPAD and WKWY will be selected using INCWGT line.
