TABLE 5.9 Checklist for Jacket/Topside Transportation Analysis — cont ' d

Check
(Yes/No)

S/N Items to Check

11 Roll and pitch acceleration data

12 Coefficients for the lateral load components due to

combinations

13 Primary and secondary load case identification

14 Load combinations

15 Chord strength reduction in the joint-can input file. (Check

F y = 2/3 F u for chords of high-strength members.)

16 Allowable stress modifiers

Analysis Results

17 Enclose load case summary for dead load case

18 Enclose reaction summary from combined analysis

19 Cross-check reaction summary values from basic motion

equations

20 Enclose member check report: review overstressed members

21 Enclose joint check summary: review overstressed joints

22 Enclose model plots: joint/group/section names, Kx, Ky, Lx, Ly

and Fy

23 Enclose deflection plots, member unity check ratio plots

Sea-Fastening Design

24 Check for adequacy of base plate connections for sea fastenings

(weld size less than the barge deck plate thickness, gusset
connections for uplift forces preferred)

25 Check for adequacy of doubler plate connection (weld, doubler

plate) on the topside members

Barge Deck-Strength Check

26 Check for barge deck transverse girder adequacy

27 Check for adequacy of weld between barge deck plate/girder for

uplift

28 Check for buckling strength of bulkheads for sea-fastening

reactions

29 Check for combined vertical/lateral loads on end bulkheads

30 Check for combined vertical/lateral loads on internal bulkheads

31 Check for barge flexibility effect of sea-fastening forces
