Modular Configurations

Flexifloat modules may be easily connected side-to-side, end-to-end or end-to-side to form larger platforms of various shapes which are suitable for all types of marine transport and construction applications. Hull shapes constructed with a proper ratio of Quadrafloat and Duofloat modules provides significant increases in structural strength and overall barge versatility.

Flexibility

A variety of Flexifloat configurations can be designed using the same number of floats. For example, the "T", "U" , "H" and square-shaped barges shown below are all assembled using 8 Quadrafloats and 2 Duofloats. Numerous other shapes are also possible.


T - Configuration

The T-Configuration provides optimal stability characteristics and economical solutions to a majority of flotation applications. This configuration allows a physical reduction in crane reach necessary to clear the forward edge of the barge. This results in increased lift capacity available in the normal working area.


U - Configuration

This configuration offers unique solutions to certain operations including dredging, drilled shafts and installations of closely spaced vertical piles. The "barge pocket" allows cranes or other machinery to be positioned extremely close to the work area with minimal initial hull inclination.


Square Configuration

The square configuration exhibits identical stability characteristics along both the longitudinal and transverse axis. A square hull form is well suited for projects that require compact barge shapes with equal reach and lift capacities over all sides of the assembly.


Rectangular Configuration

The more conventional, longer rectangular barge design can be beneficial for jobsites that have narrow waterways such as channels, rivers and locks. Additionally, it provides an ample longitudinal laydown area for longer pilings and girders.


H - Configuration

A further adaptation of the principles noted in the U-Configuration. The extended outboard rows of flotation increase the transverse stability characteristics without a requisite increase in overall hull width. "H" shaped assemblies are effective in limited access areas such as lock chambers or narrow canals.
