HYTRANS Mobile Super Water Supply Systems

Also known as the High Volume Pump or HVP, this system is in fact a Bulk Liquid Transportation system that can interest: |

| The whole point of the system is: - to carry large amounts of liquid - over long distances - whilst enabling access to open water sources At large scale fires or natural disasters such as floods and earthquakes, the main issue is always water: supply (flow and pressure), access, time, distance and manpower. It is always necessary to be able to pump from open water sources (rivers, lakes, harbours or open sea). However, due to draft limitation of conventional suction pumps, access to water is often quite difficult. HYTRANS from The Netherlands, in cooperation with Shell Subsidiary NAM, has developed a system to overcome this problem. The HYTRANS water supply system has proven to be a very effective system for disaster relief in the petrochemical industry, providing efficient water supply as the main source or as a back up. In December 2005, 14 HYTRANS HydroSub 150s were deployed at the Buncefield Oil Depot fire near Hemel Hempstead, UK. That fire was the largest post-WWII fire in Europe. HYTRANS HVPs were used for pumping water from a brook to the site 1.8km away, distributing that water on site for fire fighting and for cooling unscathed tanks, as well as to shuffled contaminated run-offs between bunds and empty tanks to avoid an ecological disaster. The HYTRANS system consists of three major components: - An innovative hydraulically driven submersible pump, allowing quick access to any open water source. The hydraulic pump pushes the water through a large diameter hose (as opposed to conventional pumps that suck the water up, with the draft limitation that we know). - A containerised diesel-driven hydraulic power pack to power the submersible pump. - Large diameter hoses to minimise friction losses allowing fast deployment at speed, up to 50km/hour, as well as mechanised retrieval with a clever semi-automatic hose recovery system in little time (30min/km of hose) with limited manpower (3 people). The HYTRANS system comes in various sizes and configurations, each aimed at specific users and applications, from 1500L/min at 10 bar to 22000L/min at 12 bar for Fire Fighting and from 4000L/min to 40000L/min for Dewatering flood affected areas. |
