Document Type and Number:
WIPO Patent Application WO1999013164
Kind Code:
A9
Abstract:
A method and apparatus for the installation or removal of large multi-ton prefabricated deck packages (16) includes the use of usually two barges (11, 12) defining a base (13, 14) 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. Each boom (21, 22) has a lifting end portion with a roller (63) that fits a receptacle (75) on the package. Tensile connections form attachments (130-134) between the deck package and barge at a lower elevational position. The variable dimension truss includes at least one member of variable length (130-134), in the preferred embodiment being a winch powered cable (130-134) that can be extended and retracted by winding and unwinding the winch.
