Eurosatory 2016: Janson Bridging’s new Janson Container Pontoon System

The Janson Container Pontoon System, code name JCP, is an innovative and very versatile system for creating floating structures in a variety of forms. The Janson Container Pontoon System will be ready for delivery before summer 2017. And manufacturer Janson Bridging is presenting it at Eurosatory for the first time.

The paramount consideration to start developing the JCP is Janson’s awareness that the consequences of climate change will undoubtedly lead to a stronger demand in the near future for a relatively cheap, simply to construct, easy to handle and easy to transport floating system for use in wetlands and flooded areas. Based on Janson Bridgings’ extensive experience in all kinds of (rental) naval projects worldwide the company started developing such a system in 2015. The main guiding principles for the design are:
1.      Modularity (strong demand for fixed grid dimensions, multiple constructions with similar components must be possible, constructions must be easy to build and easy to adjust, components must be easy to exchange).
2.      Transportability (fixed grid dimensions must be based on dimensions of worldwide modes of transport).
3.      Operational safety (linkage of components must be possible by a singular coupling which can be installed from the topside of the platform and can be visually inspected during operation).
4.      Operational flexibility (replacement of couplings must be possible under load conditions, adding components must be possible under load conditions, floating devices of different heights must be linkable)
5.      Load capacity (permissible load per square metre must answer to customer heaviest demands, strength of couplings must be guaranteed under the severest working conditions, loaded floating devices must be able to withstand resting on riverbanks)
6.      Certifiable (system must be accepted worldwide by certifying authorities)
7.      Low cost of ownership (low purchase price, simple and robust design resulting in low maintainability costs)
What came out is a multifunctional road, rail and sea transportable modular pontoon system consisting of two main components: The Janson Container Pontoon and the Janson Versaworker tugboat.
The Janson Container Pontoon is the cornerstone of the JCP-system. The pontoon is built of high strength steel with improved mechanical properties. It is available in several dimensions, based on a standard 20 feet container or based on a 40 feet container resulting in a standard width of 2.436 mm and a standard length of 6.090 mm (20 feet container) or a standard length of 12.192 mm (40 feet container). Height can vary from 724 mm to 2.896 mm. Each pontoon is equipped with container corner castings making (strategic) transport cheap and easy by road and sea as well as by rail.
Through the patented innovative IncradiLock coupling system Janson Container Pontoons are connectable to each other on all four sides. This makes the JCP-system highly versatile. It can actually serve as a kind of toolbox offering engineers all kind of possibilities to design drifters on the basis of which various floating constructions can be built, such as bridges (up to MLC T 80, MLC W 96) ferries (MLC T 80, MLC W 96), piers, harbour facilities, temporary bearings, temporary work platforms etcetera.
The new Janson Container Pontoon System has a number of distinguishing features and benefits for armies such as:
·         High operational usability and versatility
·         High operational readiness
·         Low purchase price
·         Low cost of ownership
·         Low cost of (strategic) transport
·         High sustainability

In more detail:
High operational usability and versatility.
1.      The system is modular and multipurpose. It can actually serve as a kind of toolbox offering engineers all kind of possibilities to design floating structures.
2.      The Janson Versaworker tugboat can be used not only as a tug but also as a work platform.
3.      In case of building a bridge the system is very adaptable to the water width because the bridge units can easily be separated in smaller components (up to four single pontoons).
4.      In case of building a bridge the available bridge units can be used either by using a longitudinal length of 6.090 mm or by using a longitudinal length of 9.744 mm.

High operational readiness.
1.      The system is extremely robust. It is also easy to operate and easy to maintain.
2.      Because of the interchangeability of parts and components the system as a whole is very redundant.
3.      Components and parts “off the shelf” from Janson Bridging.
4.      Long-time bridge operation because of spud pole system with far less logistical and personnel effort.
5.      Very suitable for disaster relief operations because of the wide double lane useable bridge deck (8.500 mm) e.g. enabling both extensive civilian and humanitarian aid traffic flows to pass smoothly and safely.

Low purchase price.
1.      The simplicity of design as well as the use of steel as basic building material for all system components results in a reduced purchase price compared to systems based on alloys.
2.      The same applies to the Janson Versaworker tugboat. The products’ simple design makes building each boat fairly easy and certainly swift resulting in an interesting price level.
3.      Purchase of new, expensive or special trucks is not necessary because all components of the system can be handled and transported as standard ISO containers.
4.      The systems’ modularity and versatility implies that a customer not only procures a single floating bridge or ferry. For the same price he procures a variety of applications in the field of engineering and logistics.

Low cost of ownership.
1.      All components are robust, of simple design (reduced number of parts and joints) and of high quality (materials and construction). This results in a long stretched Mean Time Between Failure.
2.      Should nevertheless parts or components get damaged then repair does not ask for any specialised maintenance personnel nor for any special equipment.
3.      Repair time is short because all parts like joints, couplings and hydraulics are easy accessible and because damaged components can be replaced quickly.
4.      The stock of spare parts can stay limited because components and spare parts are to a great extent similar and interchangeable and because Janson Bridging can deliver instantly “off the shelf”.

Low cost of (strategic) transport.
1.      All main components of the system are certified by the authorities to be handled as a standard sea container.  Auxiliary equipment such as couplings, bollards, spud poles, railings, anchoring equipment, lifting appliances, pumps, mooring lines, lifejackets, shovels and pickaxes, toolkits and maintenance kits will be containerised. This results in considerable less costs for (strategic) transport (no oversized loads).
2.      Also in general less cost for transport because standard container trucks can be used.

High sustainability.
1.      When in use as a bridge for a longer period (using the spud poles) there will be almost no emission of CO2 and other pollutants.
2.      Significantly less use of fossil fuel as well as logistical effort to keep the bridge in operation.
3.      Because of the robust design and utilising steel with improved mechanical properties wear resistance is very high resulting in usability of the system for decades and less necessity to replace components.
4.      Recycling of the steel system components is a worldwide common as well as cost effective process.
