Found an english-language presentation for the "Pontoon Boat" system GDELS developed for paramilitary Civil Defense Agency THW.
The "Pontoon Boat" system is - subject to future funding... - intended by THW to equip their "Water Dangers, Type B" specialized squadrons (47 nationwide, though that's likely to go down somewhat), which primarily provide emergency ferry and waterbourne logistics services for civil protection units. GDELS developed the system to THW requirements under a 4 million Euro research grant from the Federal Ministry of Science and Culture between 2018 and 2021.
The requirements for the system mostly stem from a straight-up replacement of existing modular pontoon ferries THW operates designed in the 1960s. When THW took over used 7-ton trucks from the Bundeswehr around 20 years ago they found that these were too heavy to be carried on the 1960s systems; since then THW has also begun operating some even heavier equipment, so the "pontoon boat" is designed to be able to also carry any of those.
All options shown save for the last ("various connectable") would be within the scope of the equipment of a single specialized squadron.
Further options not shown in the video, but mentioned by both THW and GDELS are:
- using the ramps from the last option and couple them as a fixed short deployable bridge.
- assembling a square platform as a floating helipad.
A prototype of the system was tested in 2022:
This video also shows the BASILISK USV developed within the same project. This is intended as a reconnaissance and mapping drone for the squadron for flooded areas with unknown underwater surface conditions. "Water Dangers" squadrons currently typically operate older assault boats with an installed sonar system for this purpose (in addition to - present in many cases, but not federally financed - UUVs).
The "Water Dangers" squadrons are currently in the process of having their land-side vehicles replaced. For Type B that's a MAN TGS26.430 6x6 truck with a shortened flatbed for carrying a 10' container and an installed crane and winch, along with a Hüffermann Multicarrier trailer for carrying the pontoons - alternatively 20' containers, standard swap bodies, bulk cargo or vehicles up to 12 tons. With the "pontoon boat" system they'd be pretty much fully re-requipped up-to-date for the next couple decades.
