Buckling of clad pipes under bending and external pressure
(2011)The present paper concerns the structural behaviour of clad pipes. This is a double wall pipe, composed by two pipes that are in contact through an appropriate manufacturing procedure; a thick-walled carbon steel "outer ... -
Dented externally-pressurised pipes subjected to cyclic axial loading
(2019)The present paper describes a numerical investigation of the mechanical response of externally-pressurized dented stainless-steel pipes, subjected to reverse cyclic axial loading. This is the first part of a large-scale ... -
Fatigue of welded tubular X-joints in offshore wind platforms
(2019)The paper is part of the European research program JABACO (2015-2018), on the optimization of design and construction of offshore jacket platforms for supporting large wind turbines (5 - 10 MW) in water depths ranging from ... -
Influence of lined pipe fabrication on liner wrinkling
(2019)An economical method to protect offshore pipelines against corrosive ingredients of hydrocarbons is a double-walled (also called “lined” or “bi-metallic”) pipe, in which a thick-walled low-alloy carbon steel (“outer pipe”) ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
(2011)The present paper investigates the mechanical behaviour of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and perpendicular to the pipeline axis. The interacting soil-pipeline ... -
Nonlinear dynamic response of a compliant tower under the effect of steady and unsteady sea states
(2017)The purpose of this work is to highlight the importance of considering the actual nonlinear dynamic response for the analysis and design of fixed deep water platforms. The paper highlights the necessity of applying dynamic ... -
Numerical and experimental investigation of the wave loading on a three-legged offshore wind turbine jacket platform
(2018)The purpose of this work is to examine a three-legged jacket tower support system subjected to wave loading. To this end, linear as well as nonlinear wave scenarios are investigated. The structure was designed for offshore ... -
Numerical simulation of JCO pipe forming process and its effect on the external pressure capacity of the pipe
(2017)Large-diameter thick-walled steel pipes during their installation in deep-water are subjected to external pressure, which may trigger structural instability due to excessive pipe ovalization with catastrophic effects. The ... -
Numerical simulation of UOE pipe process and its effect on pipe mechanical behavior in deep-water applications
(2015)Large-diameter thick-walled steel pipes during their installation in deep-water are subjected to a combination of loading in terms of external pressure, bending and axial tension, which may trigger structural instability ... -
On the adequacy of existing foundation schemes for offshore wind turbines subjected to extreme loading
(2017)Dictated by the world's escalating energy demands, offshore infrastructure is moving beyond the immediate continental shelf into deeper waters. Although the monopile solution has proven its reliability for many years, its ... -
Soil-pipe interaction models for the simulation of buried steel pipeline behaviour against geohazards
(2017)Hydrocarbon pipelines constructed in geohazards areas, are subjected to ground-induced actions, associated with the development of severe strains in the pipeline and constitute major threats for their structural integrity. ... -
Structural integrity of buckled steel pipes
(2015)Local distortions on steel pipeline wall in the form of buckles may constitute a threat for the structural integrity of the steel pipeline. In the present paper, experimental research supported by numerical simulation is ... -
Ultimate capacity of pipe bends under bending and pressure
(2008)The structural capacity of pressurized pipe elbows under in-plane bending is examined. The investigation is conducted through advanced finite element analysis tools. The numerical results are successfully compared with ... -
Wrinkling of lined steel pipes under bending
(2013)Lined pipes are used in energy pipeline applications (oil, gas, etc.); a corrosion-resistant thin-walled liner is fitted inside a carbon-steel outer pipe. The paper focuses on wrinkling of lined pipes (sometimes also ...
