    摘要： The invention relates to a rope connector (200) for connecting prepared ends (150sp) of two rope segments (150-1, 150-2), wherein said prepared ends (150sp) each comprise a rope eye, wherein the rope connector (200) comprises at least two complementary parts (200-1, 200-2), wherein each of said parts (200-1, 200-2) is configured with a shaped recess (210) for receiving at least part of said prepared end (150sp) of a respective one of said rope segments (150-1, 150-2), and wherein said parts (200-1, 200-2) are detachably mountable to each other to establish a firm connection there between that is strong enough to sustain the required tension capacity. The invention further relates to a rope extension system (100) comprising such rope connector (200) and a hoisting system (10) comprises such rope extension system. The invention provides for a more flexible set-up for extending the rope on-site, by simply adding more wire-rope segments via further rope connectors.

    摘要： There is described a device for use in water processing, and related methods. In various embodiments, the device has: housing sections for housing membranes for treating water in the interiors of the housing sections, wherein the interiors of the sections are separate from one another; a feed inlet for supplying the device with water to be treated; an extraction outlet for extracting treated water from the device; a distributor chamber for containing a flow of water to be treated from the feed inlet and distributing the water to be treated into the interiors of the housing sections; and a collector chamber for collecting treated water from the interiors of the housing sections and communicating a merged flow of the treated water to the extraction outlet. The device may be useful particularly in subsea systems.

    摘要： The invention relates to a drilling unit (100a, 100b) for mounting on a deck (200) of a floating vessel, the drilling unit (100a, 100b) comprising a drill tower structure (130) with a heave-compensation system for compensating vertical movements of the floating vessel due to waves. The drilling unit (100a, 100b) further comprises a winch (110) mounted at or near the deck (200), a crown block (151) mounted at a top side (140) of the drill tower structure (130) and at least one wire rope (120) provided between the winch (110) and the crown block (151). The heave-compensation system comprises a slideable support frame (150) configured to be moved relative to the drill tower structure (130) in a direction substantially parallel to the axial direction of the drill tower structure (130), wherein either the winch (110) or the crown block (151) is provided within the slideable support frame (150) such that a distance between the winch (110) and the crown block (151) is controllable, wherein the position of the slideable support frame (150) with respect to the drill tower structure (130) is controlled by at least one electric motor or linear actuator (171). Alternatively, the crown block may be dispensed with and the winch (110) is placed in the slideable support frame (150) at the top side (140) of the drill tower structure (130). The invention provides a drilling unit with an improved and overall more compact design of a compensation system.
