Abstract: A high voltage swivel, includes an annular outer element defining a cylindrical chamber around a longitudinal axis and an inner cylindrical element coaxial with the outer element and rotatable relative thereto around the axis. The inner and outer elements each include at least two axially spaced conductors rotatable with the inner and outer elements, the conductors forming at least two pairs placed with contact surfaces in mutual electrical contact. One conductor in each pair is provided at the inner element, the other at the outer element and being connected to a respective voltage line which extends to an input terminal and to an output terminal respectively, the conductors being surrounded by an insulating material. The conductors of the outer element are provided in a recess in an annular solid outer insulating ring, the conductors of the inner element are provided in a recess in an annular solid inner insulating ring.

Abstract: A vessel (1) comprises a rotatable turret (14) and a supporting structure (3) over or on the turret for supporting a swivel (5). The swivel comprising an inner and an outer ring (21, 21?; 22, 22?) which can rotate with respect to each other and which define at least one fluid distribution path from a geostationary fluid riser (19) connected to one ring (22, 22?) to a product outflow pipe (18) connected to the other ring (21, 21?). A rig (2) is mounted over the turret area above or below the swivel (5), and a substantially rigid pipe extends from the rig, through a moonpool of the turret towards the sea bed, the rigid pipe being in line with the swivel.

Abstract: A method of connecting a first floating structure to the seabed, includes the steps of: providing a second floating structure, anchored to first and second anchoring points respectively on the sea bed via at least two anchor lines, attaching the second floating structure to the first structure via a pulling device, on the side of the first anchor line, displacing the first floating structure away from the second anchoring point towards the first anchoring point, disconnecting the first anchor line from the second floating structure while maintaining a pulling force on the second anchor line via the pulling device, and attaching the first anchor line to the first floating structure. By interconnecting a temporary buoy to the vessel to be anchored via a tension member, the anchor lines of the buoy and the vessel can remain under tension at all times whereby damage to the anchor lines is prevented.
