Subsea high pressure/high temperature (HP/HT) pipelines may be significantly affected by the effects of soil structure interaction (SSI) when subjected to earthquakes. Numerical simulations are herein applied assess role deformability on seismic vulnerability an unburied pipeline. Overcoming most contributions existing in literature, this paper proposes a comprehensive 3D model system (soil + p...

The subsea anchor piles of offshore wind power floating platform structures are mainly subjected to uplift and horizontal loads, this paper focuses on the case loads. A three-dimensional numerical simulation study pullout characteristics suction in clay layers was carried out reveal movement state during pile pullout, range depth at point where is achieved (referred as range), relationship betw...

this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...

The KM3NeT EU-funded consortium, pursuing a cubic kilometre scale neutrino telescope in the Mediterranean Sea, is developing technical solutions for the construction of this challenging project, to be realized several kilometres below the sea level. In this framework a proposed DC/DC power system has been designed, maximizing reliability and minimizing difficulties and expensive underwater acti...
