Crane Barges
Deck barges can be specially built to support a working crane. This type of barge usually has a boxed stern that provides maximum flotation while operating a crane over that end. Extra strengthening is provided under the crane working area by use of additional bulkheads, internal trusses, or deck frames. Wooden crane mats should always be used to further distribute the concentrated load and provide traction for the crane. Crane barges can also be used for transportation of general cargo or as work platforms.

These barges often have spudwells and spuds. The spuds can be operated by a crane placed aboard the barge or by a spud-winch that may be installed.
