Abstract: A motor assisted movement assembly 2 is provided comprising a motor arrangement 3, which motor arrangement 3 may assist a manually controlled movement of a first structural element 5 relative to a second structural element 6. A motor element 3a of the motor arrangement 3 is adapted to detect a manual indication of a desired movement of the second structural element 6 relative to the first structural element 5 with the motor arrangement 3 being adapted to assist, e.g. support the movement by providing an additional force.

Abstract: A system for developing offshore hydrocarbon fields includes a floating hydrocarbon processing unit moored to the seabed and connected to a hydrocarbon reservoir via a riser and a wellhead on the seabed, the unit receiving and processing the hydrocarbon mixture received from the reservoir via the riser, and having equipment to separate the hydrocarbon mixture into oil, water and gas and store them in storage tanks. A gas storage buffer reservoir is placed at a distance from and isolated from the hydrocarbon reservoir. A gas export riser is connected to the floating hydrocarbon processing unit and the gas buffer reservoir to export separated gas and inject it into the gas buffer reservoir. A gas riser has one end connected to the gas buffer reservoir and another end connected to the floating gas processing unit for processing gas received from the gas buffer reservoir for enabling transportation to shore.

Abstract: A system for developing one or more offshore hydrocarbon fields includes at least one floating hydrocarbon processing unit moored to the seabed and connected to a hydrocarbon reservoir via a riser and a wellhead on the seabed, the unit receiving and processing the hydrocarbon mixture received from the reservoir via the riser, and having equipment to separate the hydrocarbon mixture into oil, water and gas and store them in storage tanks. A gas storage buffer reservoir is placed at a certain distance from and isolated from the hydrocarbon reservoir. A gas export riser is connected to the floating hydrocarbon processing unit and the gas buffer reservoir to export separated gas and inject it into the gas buffer reservoir. A gas riser has one end connected to the gas buffer reservoir and another end connected to the floating gas processing unit for processing gas received from the gas buffer reservoir for enabling transportation to shore.

Abstract: An apparatus for off-shore processing of a hydrocarbon stream, at least comprising: a jack-up platform; one or more jack-up legs rootable to a sea-bed; and one or more hydrocarbon stream processing units on the jack-up platform.

Abstract: A medical apparatus for (radiation) diagnosis or therapy can be provided with moving parts 6. Such an apparatus must be provided with a collision detection device 26, 28, 30. A known collision sensor measures the supply current for the drive motor and hence induces a high degree of inaccuracy in the collision detection. According to the invention the force applied to the moving part (image intensifier 6) is measured directly on the relevant part so as to be compared with an expected value, an alarm signal being generated when a threshold value for the difference is exceeded. The expected value is calculated while taking into account all movement and acceleration parameters of the apparatus. The expected values can be calculated in advance and stored in a look-up table or can be calculated, preferably while using a model of the apparatus, during operation of the apparatus.

Abstract: Offshore platform comprising a bottom structure (1) comprising a polygonal base (5) resting on the sea floor (2) having suction piles (10) joined to its corners and a first support frame (8) connected to the polygonal base (5) including interconnected open-ended pipes (15), conductors (33) extending from above the water surface (36) into the seabed through the open-ended pipes (15) of the first support frame (8), and at least one further support frame (22, 24) including interconnected open-ended pipes (25) extending around the conductors (33), wherein each further support frame (22, 24) is secured to the conductors (33) at a predetermined level.

Abstract: A tower structure having a central column, three support legs and a base structure which can be anchored to the sea bed by means of piles. The legs and base structure are constructed as an integral preformed base unit with a sleeve attached to the upper ends of the legs.The column is slidingly engaged within the sleeve of the base unit. A rigid connection is made between the column and the sleeve. In the erected structure, the primary load of the column is transmitted through the column and sleeve connection via the base unit to the sea bed.

Abstract: The invention provides a method of constructing an offshore tower structure having a base structure for positioning on the sea bed, a central enclosed tubular column containing services such as conductors and risers and extending from the base structure to above the water level for supporting a service platform which includes positioning the base structure on the seabed, floating the column and legs over the base structure, lowering the column and legs onto the base structure and securing them onto the latter.
