The invention discloses a conductor joint ant a method for connecting a conductor end of a first cable with a conductor end of a second cable with the conductor joint. The conductor joint comprises a tubular longitudinal sleeve (1) and an elongated element (10). The sleeve has a sleeve length Ls and sleeve openings at each longitudinal end with an inner diameter allowing insertion of the conductor ends to be connected, the sleeve (1) comprising an inner surface shaped as two tubular stairs mirrored around a radial cross-sectional area at a longitudinal center of the sleeve (1), wherein each stair comprises a lower step surface at the nearest sleeve opening oriented along a longitudinal axis of the sleeve (1), a higher step surface at the longitudinal center and a step wall (3a,3b, 3a', 3b') arranged between the lower step surface and the higher step surface oriented along the radial cross-sectional direction of the sleeve (1). The elongated element (10) arranged concentrically within said sleeve (1), wherein the elongated element (10) comprises a core rod (12) having a core rod length Lr and a terminal rod wall (13, 13') at each longitudinal end.

The present invention relates to a fault location system (10) for localization of a fault in a submarine power cable (1). The fault location system (10) comprises a pulse generating device (20) for generating an electric pulse signal and a signal analyzing device (30) configured to determine the localization of the fault by analyzing a reflection signal resulting from the electric pulse signal being reflected from the submarine power cable. The pulse generating device (20) comprises a HV DC signal generator (22), a power cable (25) connected between the signal generator (22) and an output terminal (21a) of the device 20, and a switch (28) controlled by a control circuit. The control circuit (29) is configured to:- turn the switch (28) off in order to charge the power cable (25) with power from the HV DC generator (22);- turn the switch (28) on in order to discharge the power of the power cable (25) into the submarine power cable (1).

A pipe bend (200) for a transfer line for transferring fluid is suggested. The pipe bend comprises a pipe elbow section (201). Each end of the pipe elbow section is fluidly connected with a first and a second elastic pipe section (202,203). Each elastic pipe section (202,203) permits swiveling movements around a pair of two swivel axis which are not parallel to each other. At least three swivel axis of the two pairs of swivel axis (211-214) are not parallel to each other. The arrangement of the swivel axis allows for angular movements in three dimensions to compensate pitch, yaw, and roll movements of a vehicle connected to the pipe bend.

L'invention concerne un procédé d'ignifugation d'un substrat à base de fibres de bois comprenant l'application sur ledit substrat d'une composition géopolymère. Elle concerne également les éléments ignifugés tels qu'obtenus selon ce procédé, qui comprennent au moins un substrat à base de fibres de bois, et au moins un revêtement à base d'un matériau géopolymère sur ledit substrat et leurs utilisation notamment dans le domaine du bâtiment, par exemple à titre d'éléments architecturaux, structuraux ou décoratifs intérieurs, ou pour la réalisation de chemin de câbles ignifugés.

The invention relates to dynamic power cables for submarine applications, wherein the dynamic power cable comprises at least one fibre reinforced thermoplastic composite sheath radially around a water barrier sheath providing reduced buckling of the water barrier sheath and wherein the at least one fibre reinforced thermoplastic composite sheath comprises wound fibres embedded in a thermoplastic polymer.
