Abstract: A dynamic submarine power cable including a first conductor, a first insulation system layer, a first sheath, and a first screen layer arranged between the first insulation system layer and the first sheath. The first screen layer includes a plurality of first screen wires each having a first diameter and a plurality of first polymer wires each having a second diameter which is larger than the first diameter. The first screen wires and the first polymer wires are arranged in a helical manner around the first insulation system layer. The first screen wires and the first polymer wires are arranged alternatingly along the periphery of the first insulation system layer in any cross section. A radial distance between the central axis of any of the first screen wires and the central axis of the first conductor is less than a radial distance between the central axis of any of the first polymer wires and the central axis of the first conductor.

Abstract: A welding sleeve for armoured cables including a first sleeve part arranged to receive an armoured cable, wherein the first sleeve part has a perimeter surface for welding armouring wires of an armoured cable thereto, a second sleeve part arranged to receive an armoured cable, wherein the second sleeve part has a perimeter surface for welding armouring wires of an armoured cable thereto, wherein the first sleeve part is arranged to receive the second sleeve part, the second sleeve part being axially displaceable relative to the first sleeve part, along a common central axis, between an extended position and a retracted position, in which retracted position the first sleeve part receives a greater portion of the second sleeve part than in the extended position, and a rotation preventing arrangement arranged to prevent rotational motion of the first sleeve part relative to the second sleeve part.

Abstract: A power cable and filler device adapted to bear against a first and second power cores in a power cable, including a first arced wall which defines a portion of a first circle having a first diameter, a second and third arced wall, each defining a portion of a second circle having a second diameter which is smaller than the first diameter. A chamber is formed between the first, second and third arced walls.

Abstract: An arrangement for a dynamic high voltage subsea cable including an electrically conductive core, a corrugated sheath defining a radial water barrier, an electrical insulation system arranged to insulate the electrically conductive core from the corrugated sheath, and a liquid. The electrical insulation system has an external surface and the corrugated sheath has an internal surface, and wherein the liquid is arranged between the external surface of the electrical insulation system and the internal surface of the corrugated sheath for counteracting deformation of the corrugated sheath.

Abstract: A radial water barrier is provided for a dynamic high-voltage submarine cable. The water barrier includes a corrugated metal tube having an inner diameter in a range of 50-90 mm and a corrugation pitch in a range of 6-10 mm. The metal tube has a wall thickness in a range of 0.7-1 mm and a corrugation depth of more than 6 mm.

Abstract: A geographical region having an object to be tracked is divided into subregions, where adjacent disposed subregions partial overlap one another and the overlapping portions of adjacently disposed subregions share common states. A transition matrix is used to represent the terrain in a subregion and each subregion can have N geographical states and four (4) additional transition states. A regional tracker is used to estimate state sequences for each new observation of the object. Tracking continues until the process is complete or until the probability that the vehicle is in another new subregion occurs. Tracking performed between adjacently disposed subregions is based, at least in part by, the direction represented by the transition state. Tracking into a new subregion from an adjacently disposed old subregion begins precisely where tracking for the old subregion ended using the states that are common in the overlapping portions of the adjacently disposed subregions.

Abstract: A method for target-tracking of objects via observations from a sensor, wherein a geographical region within which at least one object is present is divided into a predetermined number of states, and the geographical region is divided into subregions so that adjacently disposed subregions all contain a share of states in common. Target-tracking is initiated in a first subregion, whereupon a first observation is associated with the object, and the probable state of the object is estimated. For each new time interval, a new observation is chosen for which a new state is estimated, whereupon the estimated sequence of states in the subregion is updated. When target-tracking is begun in a new subregion, the state history from the preceding subregions is transferred to the new adjacent subregion so that the state estimate in the new subregion is based on the state history in the preceding adjacent subregions.
