Abstract: A device for loading and/or unloading of flowable media includes a buoy connected to at least one riser and a vessel provided with a pick-up space for the buoy. The pick-up space ends at the bottom of the vessel, the buoy being provided with a buoyancy device and including a first part connected to the at least one riser and a second part which can be rotated with respect to the first part. The second part is arranged for locking to the vessel. The buoy comprises a connected for connecting the at least one riser to a swivel for transfer of the flowable medium. When the vessel is connected to the buoy, its position is maintained by a dynamic positioning system.

Abstract: A device for loading and/or unloading of flowable media, comprising a buoy connected to at least one riser (6) and a vessel (30) provided with a pick-up space (77) for the buoy. The pick-up space (77) ends at the bottom of the vessel (30), the buoy being provided with buoyancy means (10) and comprising a first part (1) connected to the at least one riser (6) and a second part (11) which can be rotated with respect to the first part (1). The second part (11) is arranged for locking to the vessel (30). The buoy comprises connecting means for connecting the at least one riser (6) to a swivel (48) for transfer of the flowable medium. When the vessel is connected to the buoy, its position is maintained by a dynamic positioning system.

Abstract: Valve, especially for dosing inhibitors to prevent forming of hydrates in the exploration of oil and gas, or as a liquid choke. The inhibitor or liquid has a first and higher pressure upstream of the valve and a second and lower pressure downstream of the valve. The valve has a valve body with at least one orifice therethrough. The orifice has a substantially uniform diameter and an upstream inlet part. The inlet part has an enlarged diameter relative to the substantially uniform diameter of the orifice. The valve body is disc shaped with a plurality of parallel orifices placed equidistant from a rotational axis.

Abstract: It is common in oil extraction operations to reinject produced gas and\or water back into hydrocarbon bearing formations in order to maintain formation pressure. Conventional production facilities normally flow all formation fluids to the surface and subsequently reinject the required fluids back into the formation, which can be extremely inefficient due to the high power input required to overcome the large pressure differential between the surface and formation level. A production fluid handling method and apparatus for separating downhole at least gaseous and liquid components (16, 18, 20) of fluid produced from a hydrocarbon bearing formation (12), and reinjecting at least a portion of the gaseous and liquid components (16, 18, 20), as required, back into the formation (12). Re-injection also occurs downhole.
