DEHeavy lifters
Heavy lifters (Flo/Flo vessel)
Flo/Flo ships are characterised by their large number of ballast water tanks. These make it possible to lower the ship until the main deck is up to 30 m below the water level. This allows large floating loads to be taken on board. The load is then lifted out of the water and balanced by pumping out or blowing out the ballast water tanks. To avoid damage to the ballast water tanks from overpressure or vacuum, the internal tank pressures and levels are continuously monitored. The measurement technology and its wiring is installed in service tunnels, as all space on deck is needed for the payloads.
Level detection with VEGASWING 51
VEGASWING 51 is used as an independent level detection system in the ballast tank. Completely independent of the water density, the maintenance-free tuning fork sensor reliably detects when the water reaches the switching point. The narrow design allows recessed installation in a protective tube.
Monitoring of tank pressure with VEGAWELL 52
The pressure inside the tank must be measured continuously. VEGAWELL 52, with its ceramic-capacitive measuring cell, resists pressure shocks, abrasion and particles suspended in the ballast water. The diversely redundant double seal design of the measuring cell, ensures longterm operational reliability.
Continuous level measurement with VEGACAL 66
VEGACAL 66 is implemented for level measurement in the pressurised ballast water tank. This measuring principle permits installation from above and below the tank and the measurement it is unaffected by the pressure changes inside. The sensor can be operated at a distance of up to 30 m away from the main electronics. This allows setup and adjustment of the measuring point from within the service tunnel.
