seismic load

[darrenyee88]

Just wonder how the design of FPSO take into accoutn for seismic load?

First question is "How does the earthquake accelerations act on a Floating object?

please explain thanks

FPSO?

The relation is a tsunami

With all due respect, I have seen a similar clause in a reputed Indian specification and after many clarifications, it was revealed that maritime movements might be emulated by g values attributed to the equipment designed in PV Elite. Long shot, but it was only a quick selection in the Seismic loads page and the roll pitch etc loads have been translated in seismic loads on FPSO. There you go.

gr2vessels,
Agree seastate loadings (heave pitch and roll) are simulated by "g" accelerations for pipework and equipment on an FPSO and the Tsunami is a possible valid load for an FPSO but cannot see how Earthquake accelerations themselves are transmitted to a floating FPSO.

@DSB123 so what you mean is the seismic load on FPSO are the g loading which is also the gravitation acceleration that act on the vessel right? so is tsunami also in the same catergory as g loading
