... deposits of methane hydrate in subsea sediments within hydrate stability zones. Likewise, CO 2 hydrate can also be stored with methane hydrates in the subsea sediments. Subsea sediment beyond 500m sea depth can form CO 2 hydrate within the interstitial space of sediment (Feng et al. 2023; Kumar...

... movement in these pipelines. Therefore, the on-bottom segment is crucial for maintaining the stability of the pipeline. Estimation of wave loads is crucial for to determine the necessary weight on the pipe and reduce movement for stabilizing the pipe. This paper focuses on estimating the weights necessary...

...- induced lateral breakout of a partially-embedded pipeline on a silty seabed were conducted in a large fluid-structure-soil interaction flume. The effects of the embedment-to-diameter ratio and the dimensionless submerged pipeline weight on the pipeline lateral on-bottom stability were investigated...

... conducted for securing the existing breakwaters. Recently, an interlocking caisson-type breakwater has gained much attention to enhance the stability of the conventional breakwaters. This study investigated the dispersion characteristic of wave forces using an interlocking system which connects the upper...

... 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...

... ABSTRACT: This paper presents a design of submerged breakwater, which functions as an eco-structure in marine environment. Newly patented blocks were applied to arm the submerged breakwater for providing inhabitable space of fisheries as well as its stability. To investigate the wave...

... 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...

... ABSTRACT: Ocean-current-induced pipeline stability on sandy seabed was simulated physically in a flow flume. The process of pipeline losing onbottom stability in currents was recorded and analyzed. Experimental data show that, for a pipeline directly laid on sandy seabed, there exists a linear...
