A clearance outlet line may fluidly couple the clearance tank to the manifold. The system or method may further include features or steps for purging the residual first fluid from the fluid delivery line into the clearance tank and delivering the residual first fluid from the clearance tank to the first fluid storage tank.

A breakaway assembly including a first connector and a second connector releasably coupleable to the first connector. The assembly is movable between a first configuration in which the first and second connectors are releasably coupled and together define a fluid path through which fluid is flowable, and a second configuration in which the first and second connectors are not coupled together. The assembly is configured to move from the first configuration to the second configuration when a predetermined separation force is applied to the assembly. The assembly includes a closure valve positioned in one of the first or second connectors, wherein the closure valve is configured to be in an open position when the assembly is in the first configuration to allow fluid to flow therethrough, and to move to a closed position when the assembly moves to the second configuration to generally block the flow of fluid therethrough. The assembly includes an attraction member coupled to one of the first or second connectors, and a magnet unit coupled to the other one of the first or second connectors, wherein the attraction member and the magnet unit are magnetically attracted to each other when the assembly is in the first configuration to retain assembly in the first configuration. The magnet unit includes a first portion and a second portion coupled to the first portion that together define a channel therebetween, and the magnet unit further includes a plurality of magnets received in the channel.

A sealed and thermally insulating storage tank for a fluid that is anchored in a load-bearing structure built into a ship, the ship having a longitudinal direction, the tank having a loading/unloading tower suspended from a ceiling wall of the load-bearing structure, the loading/unloading tower including first, second and third vertical pylons defining a prism of triangular section, the loading/unloading tower carrying at least a first pump, the tank having a support foot that is fastened to the load-bearing structure, the tank having at least one sump, the first pump being arranged outside the triangular prism and being aligned with the support foot in a first transverse plane that is orthogonal to the longitudinal direction of the ship.

A breakaway assembly including a first connector and a second connector releasably coupleable to the first connector, wherein the assembly is movable between a first configuration in which the first and second connectors are releasably coupled and together define a fluid path through which fluid is flowable, wherein the fluid path includes an at least partially radially extending portion, and a second configuration in which the first and second connectors are not coupled together. The assembly is configured to move from the first configuration to the second configuration when a predetermined separation force is applied to the assembly. One of the first or second connectors has a shaft which defines or includes at least part of the fluid path therein, and the at least partially radially extending portion includes or is defined by an opening in the shaft. The assembly further includes a closure valve positioned in the one of the first or second connectors. The closure valve is configured to be in an open position when the assembly is in the first configuration to allow fluid to flow therethrough, and to move to a closed position blocking the at least partially radially extending portion of the fluid path when the assembly moves to the second configuration to generally block a flow of fluid therethrough. The closure valve includes a slider that is configured to sealingly engage the shaft to seal the fluid path when the assembly is in the closed position. The assembly is configured to be pressure balanced when the assembly is in the second configuration such that internal pressure-induced force is balanced when the assembly is in the second configuration and pressurized fluid is positioned in the fluid path.

The cleaning fluid supply system includes a first fluid storage device, a second fluid storage device, a pipeline assembly and at least one fluid drive device, and they are all mounted on the base. The pipeline assembly is provided with a main pipeline, a first branch and a second branch. The main pipeline is configured to supply the cleaning fluid to the cleaning robot. The first branch is communicated with the first fluid storage device, and the second branch is communicated with the second fluid storage device. The first branch and the second branch are both communicated with the main pipeline. The at least one fluid driving device is configured to drive the fluid in the first fluid storage device and the fluid in the second fluid storage device to flow to the first branch and the second branch, respectively.

A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.
