An optical alignment system is provided that simplifies the alignment of two vehicles, for example during a docking procedure, and provides visual cues indicating range to prevent accidental collision. The optical alignment system includes a horizontal array of Fresnel lenses including a first plurality of Fresnel lenses disposed on one side of a vertical axis and a second plurality of Fresnel lenses disposed on the opposite side of the vertical axis. One Fresnel lens of the first plurality and one Fresnel lens of the second plurality are spaced equidistant from the vertical axis and form a first pair, and the Fresnel lenses of the first pair are arranged so that light paths therefrom converge along the vertical axis at a first distance behind the horizontal array of lights.

Device for a double hose structure (11) with an inner main hose (12) and an outer cover hose (13) defining an annular space (14) intended to give the hose buoyancy in water, and where at least one end is provided with a coupling member (15) forming a mount for the main hose (12) and the cover hose (13) and which at a free end merges into a threaded portion (22) for connecting the hose assembly (11) to an auxiliary connection. The coupling member (15) comprises an inner coupling sleeve (16) which is tightly connected to one end of the main hose (12) and an outer coupling sleeve (18) which is tightly connected to the cover hose (13), the inner (16) and outer coupling sleeves (18) being mutually connected to form a liquid tight termination of the annulus (14) by means of an ring-shaped plate (30). The ring-shaped plate (30) is attached with a number of screws (25) through holes (29) only to the outer sleeve (18), the ring-shaped plate (30) being forced against a shoulder (20) of the inner coupling sleeve (16) by a ring nut (40) with internal threads that match external threads (21) on the inner sleeve (16).
摘要:
A sealed and thermally insulated tank of which the wall is fixed to a bearing wall, the tank wall comprising a secondary thermal insulation barrier retained on the bearing wall and a secondary sealing barrier supported by the thermal insulation barrier; and a primary insulation barrier rigidly connected to the secondary element of the tank by fastening means linked to the secondary insulation barrier. The fastening means comprise a metal plate (301) fixed in a counterbore of a rigid plate (303) of a primary insulation block (13) adjacent to the secondary sealing barrier (304), and a protruding member (310), which is linked to a secondary insulation block (1) located perpendicular to the plate, said protruding member having a threaded head in order to engage with a nut (314) which, when screwed in, directly or indirectly exerts a force on the retaining area of the plate in the direction of the bearing wall (3).
摘要:
A valve is provided for use in a fluid flow line with first and second parts connectable to define a fluid flow path through the valve. A first valve member (36) is operable in the first part and a second valve member (38) is operable in the second part, and the valve members are arranged for movement between an open position and a closed position for shutting off fluid flow. The valve includes a closure mechanism (46) for activating movement of the valve members from the open position to the closed position, and a separation mechanism (48) for allowing the first and second parts of the valve to separate from one another. The valve has a fluid transfer mode of operation and a separation mode of operation. In the fluid transfer mode of operation, the first and second parts of the valve are connected together, the first and second valve members are in an open position and fluid can flow along the flow path through the valve. In the separation mode of operation, the separation mechanism is operable to separate the first and second parts of the valve, after operation of the closure mechanism.
摘要:
The invention concerns an arrangement for emergency release of a hose end valve (13) from its connected position with a connector valve (14) which is connected to receiving assembly (90) arranged on a first structure (80) located in water. The hose end valve (13) is provided at a hose end (63) of a hose which carries fluid especially LNG and/or vaporized LNG, and a first end portion of a hose end suspension line (27) is attached to the hose end valve (13), and is suspended in a support structure (200) by at least one line guiding element (31, 28,). A a second end portion of the hose end suspension line (27) is attached to a counterweight (22), wherein the at least one line guiding element (31, 28) is arranged in an elevated position compared to the position of the hose end (63) with the hose end valve (13) and the position of the counterweight (22), thereby providing for a weight balancing relationship. In an emergency release mode the hose end valve (13) is separated from the connector valve (14), and as the weight of the hose end (63) and the hose end valve (13) without the connector valve (14) is smaller than the counterweight (22), the counterweight (22) causes the hose end (63) with the hose end valve (13) to be pulled away from the receiving assembly (90). The invention also concerns a method for emergency release.

The invention concerns arrangements for connection of at least one hose carrying fluid especially LNG and/or vaporized LNG. A hose end (63) of the at least one hose has a hose end connector (91) to be connected to a receiving assembly (90) on a first structure (80) located in water. The hose end connector (91) is provided with guide means (102) and the receiving assembly (90) is provided with receiving means (71). The arrangement includes handling means for controlling the hose end connector (91) to position the guide means (102) into the receiving means (71) and accommodate the guide means (102) in the receiving means (71) so that the guide means (102) is supported in the receiving means (71) and the weight of the hose end connector (91) is transferred to the receiving means (71). The hose end connector (91) has a connecting position with a receiving pipe coupling (15) in the receiving assembly (90), with one receiving pipe coupling (15) provided for each hose end connector (91). The invention also includes methods for connection and disconnection of at least one hose carrying fluid especially LNG and/or vaporized LNG.
