Abstract: La invención se relaciona con un acople ( coupling ) mejorado para la unión de tuberías de características según los estándares API, para la extracción de petróleos desde pozos, cuyas características mejoradas, según el nuevo desarrollo, consiguen un diseño hermético del acoplamiento y, más específicamente, se relacionan con el mejoramiento de roscado en las uniones mediante apoyo de fabricación de las mismas tanto en terminales de pozo como en la unión de las roscas redondas, con sistemas de fabricación computarizados y con la incorporación de un hombro que está ubicado interiormente en el acople para lograr, primero, eliminar espacios libres que produzcan turbulencias en el acople y, segundo, formar un cierre hermético metal-metal y además un sello flexible de nitrógeno hidrogenado, colocado por detrás de los hombros, que garantizan la hermeticidad total de la unión.

Abstract: The present invention relates to an offshore system comprising: • - a tower to be positioned on a floating body (3) and defining a substantially vertical firing line (9); • - a mobile working deck (15) which is moveable along the firing line within a motion range which is the sum of an elevation motion range and a heave compensation motion range; • - a heave compensation system to provide heave compensation of the mobile working deck within the heave compensation motion range; • - an elevation system to position the mobile working deck within the elevation motion range; and • - an overload protection system configured to detect an undesirably big acceleration of the mobile working deck, and - in the event of a detected acceleration - to control the elevation system such that the mobile working deck motion in the elevation motion range is opposite to the motion in the heave compensation motion range.

Abstract: A robotic system with a robot and enclosure (100), the robotic system configured for EX Zone 1 certification. Fasteners attaching a panel (80) to a housing (82) of the enclosure can be positioned away from a seal (122) of the panel, with the seal sealingly engaging the panel (80) and housing (82) when the panel is attached to the housing. The panel (80) overlapping a portion of the housing (82) when attached to the housing. The panel (80) can be rotationally attached to the housing (82) by one or more hinges (250). The panel (80) can be configured to assist operators with manual manipulation of the panel by attaching detachable handles (200) to the panel.

Abstract: A core tube handling device can be used with exploratory drilling rigs. The device can include a slew arm mounted on the rig's mast and a pivot arm mounted on the slew arm. When the slew arm is adjacent to the mast, clamping devices on the pivot arm can grasp and hold a core tube from the drill string. The slew arm can pivot away from the mast and align the pivot arm with a tray that receives and holds the tubes. The pivot arm can pivot to a position proximate the tray and release the tube. The tray can be rotatable and translatable to facilitate transfer of the tube from the pivot arm to the tray.

Abstract: A method of lowering a discrete load (32) from a pipelay vessel comprises: holding a rigid rod (30) on an upright launch axis where the rod extends through a hold-back system (26); coupling a lower end of the rod to the load; connecting a wire (24) to the load either directly or indirectly via the rod; operating the hold-back system to advance the rod downwardly, hence submerging the load, while the weight of the load is suspended from the hold-back system via the rod; when the load is underwater and beneath the splash zone, transferring the weight of the load directly or indirectly from the hold-back system to the wire; and continuing to lower the load in the water, suspended directly or indirectly from the wire. The method may be reversed to recover a load from a subsea location, such as when lifting a wellhead or blowout preventer from the seabed.

Abstract: An underwater steel catenary pipeline riser (SCR) lifting frame (1) comprises a lift frame foundation (10) and an SCR lifting frame (20) comprising a lift frame interface (21) adapted to be connected to the lift frame foundation; a foundation interface (50); a lift guide (30) configured to accept the lift frame foundation; and a lift (32) slidably disposed about the lift guide, the lift comprising an SCR pull head interface (31) configured to be connected to an SCR pull head (131). The underwater steel catenary pipeline riser (SCR) lifting frame (1) and systems using it allow for flex joint repair/replacement subsea which do not require large winches, deck re-enforcements, steering winches, and heavy crane lifts required by facility mounted winches above water and also reduces required heavy lifting and overall complexity of flex joint replacement.

Abstract: Embodiments of the present disclosure describe a piston cylinder arrangement including an inner barrel (18) positioned within an outer barrel (12), being linearly moveable along an axis (56). A primary sealing assembly (28) at an upper end (40) of the outer barrel includes a plurality of seals (74) positioned to block debris from entering an interior chamber (24). Additionally, an end cap (40) is coupled to the inner barrel (18) and an end cap diameter is greater than an inner barrel outer diameter. Moreover a secondary sealing assembly (90) is arranged between the end cap (40) and the primary sealing assembly (28) and includes a plurality of secondary seals (74) positioned to block debris from entering the interior chamber (24) of the riser tensioner (10), wherein the secondary sealing assembly (90) reduces a stroke length of the inner barrel (18) when installed above the primary sealing assembly (28).
