We need some help to design for 2 sectional barges, something like you see at http://www.bargesystems.com/pictures.htm
Each section would be 40 ft. long and 8 ft. wide. The 2 sections would be united by a bridge, making the platform as wide as possible but at least 3 ft. wider. Ideally, the sections would be united by removable beams that get inserted in each section and then locked into place. To make it even more rigid, 3 overhead frames would be placed at very end and center of the barges (say 19 wide, 10 ft. high) that would also serve as a light roof support (we're in Panama: either it rains or the sun is shining like crazy).
Ideally, those frames simply have to be put into existing 'holes' with a very simple locking device. A
The load capacity of the total platform doesn't have to be more than about 30.000 lbs. It will only be used on inland waters. A support structure for an outboard is also required.
Part of the section would house a diesel tank (2x 250 gal. or so); one a fresh water tank (also 2x 250 gal.); we'll need area a little bit reinforced to accommodate a 25 KW genset....
And maybe a very simple ramp on the side
What would be best: steel or alum? I understand alum. doesn't corrode but you need more of it to give the same strengh and a few sacrificial anodes on a steel construction should help too.
The design would have to include the files so a CNC machine can cut all the required pieces and they only have to weld things together here in Panama.
