A bearing system for a rotating turret mounted on a vessel includes upper radial and axial bearings placed on a stiff bearing support ring. The bearing support ring is isolated from deflections in the vessel's caisson. Through the isolation, the radial and axial bearings are less affected by deflection of the vessel for example due to waves. The bearing support ring is supported vertically by a system of hydraulic cylinders serviced by multiple hydraulic systems for redundancy. The bearing support ring alternatively can be supported by an articulated steel structure.

Bearing support system and method for a turret on a vessel

A bearing system including a wheel assembly transmitting load to a damping assembly, wherein the wheel assembly is configured to rotate angularly relative to the damping assembly.

Bearing system for turret on a vessel

The invention regards a manifold for fluids, comprising a housing () with a center axis () and a number of fluid apertures () through the walls forming the housing () and a fluid diverter system (), comprising a fluid diverter element () mounted in the system () selectively rotating around an axis, comprising an axial outlet () and an inlet () which may be positioned in connection with one fluid aperture () in the housing. The fluid diverter system () is axially insert able into the housing () and further comprises a ring element (), with an outer configuration complementary to an inner configuration of the housing (), which ring element () is positioned around the fluid diverter element () and connected to the fluid diverter element (), and which ring element () comprises fluid apertures (A,B) corresponding to the fluid apertures () in the housing.

Manifold

An arrangement for directing a fluid flow or a tool transported in a fluid flow in an under water structure includes plural flow line arrangements each including at least one flow line, and at least two distribution devices to be varied between at least two positions. One distribution device connects at least two flow arrangements providing for the selection of the fluid flow pattern directing the fluid through the distribution devices and the flow arrangements depending on the position of each of the distribution devices. A method directs a fluid flow or a tool transported in a fluid flow.

Arrangement for directing a fluid flow

A resilient (slide) bearing device, for example for use in connection with support of a rotating element in a vessel, where the bearing insert comprises devices for gradual absorption of loads to which the bearing is exposed. This is achieved by the devices for gradual absorption of loads comprising two or more elastic elements with different modulus of elasticity, where the elements are furthermore placed in layers. A method for maintenance and service of the device is also presented.

Bearing

A tanker () is converted to a floating production ship by a vertical opening () being cut out in the hull () and a cassette-like plate structure () inserted in the opening. The cassette () is composed of plate elements () which are designed to fit and connect with the cut elements in the hull's opening. The cassette () will thereby form part of the ship's hull strength. The cassette has a vertical shaft () for mounting a turret () in/near the ship's bottom area. The turret () is wet-mounted in the shaft.

Method for conversion of a tanker

A geostationary anchoring and riser arrangement in a vessel comprises a rotating body (), which is mounted in a vertical shaft () in the vessel () by axial and radial annular bearings (). Above the upper axial and radial bearing () is mounted a dynamic primary seal (), thereby establishing a dry space above the bearings, in the shaft (). Under the bearing is mounted a secondary seal (). A fluid manifold () is placed in the dry shaft space.

Geostationary anchoring and riser arrangement on a ship

The present invention relates to a connection system and a method for connecting and disconnecting a floating unit to and from a buoy which is connected to a subsea installation, where the buoy comprises a first connection device for connecting pipes and/or lines for transfer of fluid, control signals and/or electric power between the buoy and the floating unit. The connection system further comprises a support structure which is laterally movable relative to the floating unit and a swivel stack arrangement movably mounted on the support structure. The swivel stack arrangement comprises a second connection device for connecting to the first connection device in the buoy; shut-off devices for opening and closing at least one of the pipes and/or lines in the first and second connection devices by connecting and disconnecting the buoy; and a turret bearing for rotating the buoy relative to the floating unit.
