Barge and walkway connection system

A modular pump barge and walkway system having a modular subsystem of pump barges and a modular subsystem of walkways releasably attached thereto. Each of the pump barges has a top deck and four side walls, wherein each of two oppositely disposed side walls has a recess disposed therein with a bottom shelf and a pair of holes. Each of the barges has a link pin assembly for interconnecting with an adjacent barge, comprising a support plate and a pair of vertically disposed pins, the support plate arranged so as to be removably attachable to the top deck so as to cover the recess, the pins being disposed so as to be mated with and removably inserted into the pair of holes disposed within the bottom shelf of the recess when the support plate is attached to the top deck. A link plate has a pair of parallel slots juxtaposed so as to allow placement therethrough of the pins of the link pin assembly, the link plate being removably and slidably inserted between the support plate and the bottom shelf of the recess when the link pin assembly is attached to the barge. Thus, the link plate provides interconnection of adjacent barges with independent vertical translational movement therebetween. The modular subsystem of walkways also has a plurality of floating walkways interconnected to each other in serial fashion at each of two oppositely disposed ends thereof in pivotable hinged relationship therebetween.
