... Abstract In recent years, the use of suction pile foundations in deep-sea drilling operations has been increasingly adopted worldwide. Suction piles have a long service life and are difficult to maintain, so there is a risk of fatigue failure during drilling. This necessitates a study...

... on-bottom stability during installation. This paper intends to highlight the unique challenges and complexity of Rosmari Marjoram Offshore Platform (RMP) jacket foundation design, and how the team successfully address the issues. The ‘Bespoke’ skirted mudmat foundation option was proposed whereby the sizes...

... gas hydrate formations in the sea area. Zhu Zhenyu et al. considered the shear effect of soil on the barrel when the barrel rotates, proposed a model for calculating the horizontal bearing capacity of a barrel-shaped foundation, and deduced the formula for calculating the horizontal bearing...

... Abstract Calcareous soil type is found at many locations, requiring careful selection of foundation type. Calcareous soil is mostly or partly composed of calcium carbonate in the form of lime or chalk derived from the underlying chalk or limestone rock. North-West Shelf of Australia...

... faults, and later map the seismic contours to the local soil condition offshore Malaysia to develop the spectral response map, and later the response spectrum for shallow and deep foundations to be used for the earthquake analysis for its facilities offshore Malaysia. earthquake analysis...

... Abstract A combined offshore jacket structure and foundation concept is presented, which is installable from a jack-up drilling rig. This novel system integrates the various components with extensive track record in both the offshore oil & gas and windfarm industries. It is founded...

... Abstract In order to improve the vertical and lateral load bearing capacity of the drilling conductor, composite design of bucket foundation and drilling conductor was studied. The bearing behavior of composite conductor subjected to lateral and longitudinal external loads was investigated...

... design life. SPT is a traditional jacket with integrated suction pile foundation, which triggered significant benefit and long term cost reductions in the fabrication and offshore installation. The 1100 MT jacket is designed using suction pile technology that enables the platform to be relocated...

... Abstract Local scouring is a process whereby bed materials are removed around a marine structure due to the resultant disturbance of the uniform fluid flow. When not managed properly, scouring can result in a significant reduction in the stability of a foundation and a premature failure...

... and the potential extent of soil liquefaction beneath the RSS, which is founded on a large skirted raft foundation. Extensive site specific laboratory test data, defining the material behaviour during and after cycling, was collected to provide the necessary input to this analysis. Significant areas...

... Facility (CPF). The foundation for the RSS comprises a skirted raft approximately 69 m x 38 m in plan with a central cut-out and 6.8 m deep skirts installed in uncemented carbonate sediments through a combination of self penetration and suction assistance. A 40 year design life combined...
