摘要： The invention relates to a vessel (1) comprising a riser and/or tendon tensioning construction. A connector, such as an arm or deck structure (15), is suspended from cables (12, 13) or pivot arms on the vessel. The connector carries two or more risers (3, 4) and/or tendons extending from a subsea structure to above water level (5). The free end of the cables or pivot arms is attached to a weight (16, 17) for exerting a tensioning force on the riser (3, 4) which is substantially decoupled from pitch, roll and heave motions of the vessel. One embodiment of the vessel according to the invention is characterized in that the free end of the tensioning member extends outside the hull (23) of the vessel or in a well in the vessel such as to be located below water level (5). Hereby the movements of the weight upon pitch, roll or heave motions of the vessel are limited and additional space on the vessel is made available for production or processing equipment. In one embodiment the connector is carried by cables (12, 13) and sheaves (19, 20) that are supported on two spaced apart mounting arms (21, 22) above deck level. Weight guiding elements may be provided on the vessel or on the seabed or may be formed by the risers themselves for preventing lateral movement of the weights (16, 17) and preventing damage to the risers. Other embodiments comprise flexible lines as a tensioning member connected to the seabed. To further reduce movements of the weights, the cables or pivot arms can be attached to the connector at the side of the centre line of the vessel, opposite to the side of the tensioning weight.

摘要： The invention relates to an anchoring system comprising a vessel (1) and one or more anchor lines (11, 12) extending from a first anchor (13, 15) to a pulling device (22, 23) on the vessel and from there on to a second anchor (14, 16). The anchor line may extend transversely to the length direction of the vessel (1), or may extend parallel to length direction of the vessel, offset from the longitudinal or transverse centrelines. The anchoring system of the present invention provides an active semi-weathervaning capability whereby heave and roll motions may be significantly reduced. Accurate station keeping may be achieved with a relatively small number of pulling devices, the pulling force of which can be relatively small.

摘要： The invention relates to a method of connecting two or more elongate connection members (105) between the seabed and a floating vessel (106), the vessel carrying a connector (102) which is suspended from the vessel by at least two spaced apart suspension members for relative displacement of the connector with respect to the vessel, at least one suspension member being connected to tensioning means (109, 109') for exerting an upward force on the connector, the method comprising the steps of: a) attaching one or more connection members to the connector, b) increasing the tensioning force of the tensioning means, or vice versa, and c) repeating steps a and b until the connection members are installed between the vessel and the seabed. In one embodiment a supporting deck (108) is situated above the connector (102), a first section (105) of a connection member extending from the seabed to the connector (102) and being detachably connected to a second section (104) of the connection member via coupling device (103), the second section being supported by the supporting deck (108). During stormy conditions, the drill string may be disconnected from the drilling rig, the drilling riser being suspended from the blow-out preventor.

摘要： The invention relates to a method of welding two generally rod-shaped structures (5, 6) of a fluorine-containing plastic material in a butt weld to form a closed-loop construction. The structures may comprise sealing or backup rings for use in high pressure swivels. The method comprises steps of: placing the end faces of the structures in a contacting relationship by supporting each structure in a clamping device (3, 4) at a distance from its end face, and applying heat to the end parts of the structures that project from the clamping device. The end faces are pressed together by moving the clamping devices (3, 4) towards each other such that a welding pressure of between 0.05 and 0.5 Nmm-2, perpendicular to the end faces, is transmitted from the clamping devices to the end faces via the end parts of the structures, wherein the distance of the heating element from the end parts is sufficient to substantially prevent the heated parts of the structures to contact the heating element (10). The heating element surrounds the end parts along a substantially closed contour, and may comprise two segments which can be hinged into an open or closed position to be removed from the completed weld. The heating element may be energized in accordance with a predetermined heating profile, wherein the temperature of the weld area is measured and the heating operation of the heat generating member is increased or decreased to transmit and absorb heat from and into the heat reservoir member such that the temperature of the weld area is maintained within a predetermined margin around the heating profile. By using the method according to the present invention a very uniform and non-deformed butt weld can be produced under accurate temperature control of the weld area. Because the heating element does not directly contact the inner parts a uniform temperature distribution throughout the sealing volume can be achieved without degradation of the fluorine containing plastic material.

摘要： A sealing arrangement (6, 20, 37) to be positioned between two adjacent members (2, 3; 12, 13; 26, 27) between which a fluid cavity (4) is defined. Such a sealing arrangement is by example used in a swivel structure. If the exerted pressure is considerable two members will move from each other resulting in a larger spacing of the gap between them. During increasing of the pressure the requirements set to sealing do increase. According to the invention it is proposed to provide the members (2, 3; 12, 13; 20, 27) with L-shaped extensions and inverted L-shaped extensions (10, 11; 19, 21; 29, 30; 34, 35) which engage into each other and in between a spacing is defined for accommodating the sealing. If the pressure of the fluid in the cavity arises the spacing for the sealing will substantially decrease.

摘要： The invention relates to a vessel comprising a hull (1) and a cylindrical turret well (3). The vessel can weathervane around a geostationary turret (4) located in the turret well. At least one swivel (7) is supported on the turret. According to the invention, the inner wall (10) of the swivel is connected to rotation drive means (18), which can thereby be reduced in size and which allow the full swivel weight to be transferred directly to the turret. In one embodiment the inner wall (10) of at least one swivel, preferably the walls of a swivel stack, is rotatably connected to a swivel support structure on the turret via a bearing (17). The rotation drive means (18) are adapted for rotating the inner walls (10) in conjuction with the vessel. In this way relative displacements between the swivel (7) and the turret (4) are reduced such that the layout of the pipe lines connected to the swivel can be simplified by the omission of expansion loops. As the weight of the swivel is carried by the turret, the rotation and pipe support structure can be relatively small.
In a second embodiment the outer walls of the swivel stack are fixedly connected to the turret. In this way separate rotational drive means for the outer walls can be omitted.摘要翻译： 本发明涉及一种包括船体（1）和圆柱形转台井（3）的船舶。 船只可以在位于炮塔井内的地球静止转塔（4）周围进行风向标。 至少一个转台（7）支撑在转台上。 根据本发明，旋转体的内壁（10）连接到旋转驱动装置（18），由此可以减小其尺寸并允许完全旋转重物直接传递到转台。 在一个实施例中，至少一个旋转件的内壁（10），优选地是旋转叠层的壁，经由轴承（17）可旋转地连接到转台上的旋转支撑结构。 旋转驱动装置（18）适于与容器结合旋转内壁（10）。 以这种方式，减小了旋转体（7）和转台（4）之间的相对位移，使得通过省略膨胀回路可以简化连接到旋转体的管线的布局。 当旋转体的重量由转台承载时，旋转和管道支撑结构可以相对较小。 在第二实施例中，旋转堆叠的外壁固定地连接到转台。 以这种方式，可以省略用于外壁的单独的旋转驱动装置。
