Paper Number: ISOPE-P-12-055
... ABSTRACT: When tides flow over the ocean floor, they exert dynamic pressure on the porous seabed, and consequently result in oscillatory pore pressure and seepage in the seabed. Stability of the large-diameter pipelines under construction immersed in the seabed may be influenced by the excess...

... based structures are used at Sakhalin-2 field. But, it is known that for a sea depth 60 m and more the gravity-based platform stability for Sakhalin seismic conditions requires huge amount of solid ballast and very high pressure on soil and, correspondingly, the piled substructure requires large number...
