Effect of Geometrical Irregularities on Fatigue of Lead Sheathing for Submarine High Voltage Power Cable Applications
Moreno, Edgardo; Viespoli, Luigi Mario; Johanson, Audun; Wan, Di; Alvaro, Antonio; Soma, Aurelio; Berto, Filippo (Peer reviewed; Journal article, 2021)High voltage subsea power cables are typically composed of several layers, including: a conductive core, a dielectric layer, a ductile metallic watertight barrier and a series of radial and axial armours and polymer layers. ... -
Fatigue life assessment for a welded detail: advantages of a local energetic approach and experimental validation
Viespoli, Luigi Mario; Berto, Filippo; Soma, Aurelio (Journal article; Peer reviewed, 2018)In modern civil buildings, as well as in mechanical and naval constructions, welding is a widely diffused technological process. The fatigue assessment, as design or verification procedure, of a welded joint to evaluate ... -
Tape winding angle influence on subsea cable sheathing fatigue performance
Viespoli, Luigi Mario; Panza, Luigi; Johanson, Audun; Alvaro, Antonio; Soma, Aurelio; Berto, Filippo (Peer reviewed; Journal article, 2020)A fundamental component of subsea power cables is the thin galvanized steel tape winded around the dielectric and sheathing layer in order to prevent permanent thermal cycling induced deformation. The pressure state induced ...
