ABSTRACT:
A method and apparatus for the installation or removal of large multi-ton prefabricated deck packages includes the use of usually two barges defining a base that can support a large multi-ton load. A variable dimensional truss assembly is supported by the barge and forms a load transfer interface between the barge and the deck package. End caps are removably connected to each of a two diagonally extending, longitudinal members of a boom portion of the truss assembly. Upper and lower connections form attachments between the end caps and the deck package at the upper elevational positions on the deck package. Tensile connections form attachments between the deck package and barge at a lower elevational position. The variable dimension truss includes at least one member of variable length, in the preferred embodiment being a winch powered cable that can be extended and retracted by winding and unwinding the winch.
