I am designing a flare boom for an offshore platform. I have the following information provided to me regarding the platform:
Phase Pitch/Trim Angle Horiz Accel. Vertical Accel.
(Deg) (m/s^2) (m/s^2)
Tow 20.0 9.6 15.1
At Site 0.17 0.69 9.9
Notes:
1) Horizontal accelerations include gravitational effets due to pitch/trim angles.
2) Vertical Acceleration includes gravity.
My question is whether I can simulate the effects of motion by applying an equivalent G-Force in the horizontal and Vertical directions. For example for the "Tow" Condition, can I use 9.6/9.8 = 0.98g for Horizontal and 15.1/9.8 = 1.54g for vertical? I realize that these loads have to be combined with the other applicable loads per API RP 2A.
Also, how would the Pitch/Trim angle be considered given that the Horizontal accelerations indicate that Pitch/Trim angles have already been included (Ref. Note 1)?
Thanks,
Meca
