A coupling system for fluid transfer between a bow area of an elongated vessel and a hydrocarbon delivery installation at open sea. The system includes a support frame for suspending the system to the vessel and a fluid receiving tube segment fixed to the support frame comprising a coupling device arranged at a first end of the tube segment and that establishes a leakage free coupling with a hose valve. The system further includes a remotely controlled drive system that simultaneously exerts a transverse force generating pendulum movements of the coupling device in the transverse plane, a longitudinal force generating pendulum movements of the coupling device in a longitudinal plane, and a rotational force generating rotational movement of at least part of the coupling device iteratively adjusting the rotational position of the at least part of the coupling device by regulating the rotational force.

Technology is provided for a fluid conduit assembly for connecting orthogonally oriented connections. The assembly includes a first tube arcuately extending from a first proximal end portion to a first distal end portion. The first proximal end portion includes a first fitting connectable to a first fluid connection. A second tube arcuately extends from a second proximal end portion to a second distal end portion. The second proximal end portion includes a second fitting connectable to a second fluid connection that is orthogonally oriented with respect to the first fluid connection. A coupling connects the first distal end portion and the second distal end portion. The first rigid tube is rotatably positionable with respect to the first fluid connection whereby a first distal axis and a second distal axis are substantially coaxially aligned when the first fitting and second fitting are connected to the first and second fluid connections, respectively.

A ventilation system is operable to ventilate gases from an enclosed building. The ventilation system broadly includes a ventilation tube, a ventilation fan, and a flexible flow-through coupler. The tube is operable to extend into and out of the building for transmitting gases along the length of the tube. The fan is in fluid communication with the ventilation tube and is located to pump gases along the tube length. The coupler connects and fluidly communicates the fan to the ventilation tube, with the flexible coupler isolating at least part of the ventilation tube from vibration caused by the fan. The coupler comprises a flexible material with a Shore A hardness less than about 50.

A fire extinguishing system of an aircraft including: a fire extinguishing nozzle that is provided on an installation member forming a compartment of the aircraft; and a fire extinguishing pipe that is provided on a support structure supporting the installation member from a back side, and supplies a fire extinguishing agent to the fire extinguishing nozzle, wherein the fire extinguishing pipe includes a first pipe that is supported by a first support member constituting the support structure, a second pipe that is supported by a second support member constituting the support structure and crossing the first support member, and a tube having flexibility that connects the first pipe and the second pipe.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof.
