Part 17 - Flotation and Upending SACST 培训教材.pdfVIP

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. Leg definition line LEGDEF will be used to define 101L-501L as LEG1, 103L-503L as LEG3, 105L-505L as LEG5, and 07L-507L as LEG7. Crane hook definition line HOOK added to define hook label as MAIN; Four SLING lines
