The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. In embodiments, a coupling device may be configured according to lookup table that defines compatible configurations of connectors. The configurations may be based on the presence and absence of interference members at standardized locations on the respective connectors. The interference members may include posts that mechanically interfere with other posts, but can be inserted into holes when two connectors have a compatible configuration.

An offshore power generation system comprising: a floating portable platform having one or more OTEC heat exchange units, one or more turbine generators, a water intake and discharge system, a mooring system; and a fixed manifold having one or more cold water intake connections in communication with a cold water pipe, and one or more cold water discharge connections in communication with the water intake system of the floating platform via an intermediate cold water conduit, wherein each cold water discharge connection is detachable from the intermediate cold water pipe.

A pipe end fitting assembly that includes an outer body having an outer surface, an inner surface defining a first bore, and an end surface, and an inner body having an inner surface defining a second bore and an outer surface. A portion of the inner body outer surface is secured to the outer body inner surface. A passage formed in the outer body includes a first portion extending from the end surface and parallel to the first bore, and a second portion extending from the outer body outer surface to the passage first portion. A pipe end is disposed around and secured to a portion of the inner body outer surface. A jacket is disposed around the pipe and has an end secured to the outer body outer surface. The passage portions are in fluid communication with each other and a space between the jacket and the pipe.

A member linking mechanism, pairable with a gas chromatograph, which has a small and simple configuration, and is capable of linking two members together with a required fastening force even in a limited space. The member linking mechanism includes a first member having a member linking part with an opening at its distal-end surface; a second member to be linked to the member linking part of the first member; an elastic sealing member sandwiched between the first and second members so as to seal the opening of the distal-end surface of the member linking part; and a linking member for linking the first and second members together via pressure. The linking member includes: a linking member body configured to hold an end part, of the second member, adjacent to the first member; and an elastic deformation part provided to the linking member body.

An embodiment provides a hydraulic fluid line guard, including: a main guard formed with an open bottom and enclosed top and sides; the main guard having a length dimension that is larger than a width dimension; and an arm attached to the main guard; the arm comprising an attachment that attaches the main guard about a hydraulic fluid line such that a detachable junction point of the hydraulic fluid line is housed within and under the main guard and is accessible from below. Other embodiments are described and claimed.

To provide a safety joint capable of preventing moment generated by swinging of a filling hose and surely separating the safety joint to a hydrogen filling apparatus side member and a vehicle side member when a tensile force more or equal to a predetermined value is applied to the filling hose. The safety joint 100 according to the present invention includes a plug (10: vehicle side member) with a cylindrical shape in which a passage (1A: in-plug passage) is formed, a socket (20) in which a passage (21A: in-socket passage) continuing to the passage (1A) in the plug (10) is formed, and a shut off valve mounted on the passage (21A: in-socket passage) in the socket (20), the shut off valve opening when the plug (10) being inserted into the socket (20) and closing when the plug (10) being disconnected therefrom, wherein central axes of the passages of the plug and the socket do not form a straight line (but those are orthogonal with each other for instance), a filling hose (61) is connected to the plug (10), and a hose guide (70, 70A) for limiting movement of the filling hose (61) at a position separated from the plug (10).
