Trading and engineering company focusing on process pumps
Copenhagen Pump was contacted in 2011 by Naval Arcitects and asked to dimension an Anti Heeling (anti heeling) project on the Hundested-Rørvig ferry.
Due to the dimensions of the ferry, accidental heeling occurred when loading vehicles. Relatively small stabilization tanks on the sides of the ferry, together with a pumping system that should be able to be operated both from machinery spaces and from bridge, were to solve the task.
It is basically the same frost-proof liquid that is moved between the two tanks in starboard and port respectively.
Normally, high-capacity propeller pumps are used for this type of task. However, due to the capacity of the ballast tanks and for control reasons, an Allweiler Excenter snowmobile pump was used a little unconventional.
The Eccentric Screw Pump has the advantage of being fully reversible while acting as a lockout valve. Bridge and machine control are provided with level indicators so that one can keep up with the movement of the liquid between the containers.
Project
Control: blackboard project with remote board on the bridge
Pump: Allweiler AEB 1 1450 can give up to 1.5 m3/ min at 400 rpm
Instrumentation: Pressure transmitter
Engine valves: 2 pcs
Service: The plant has been working for 2011-2021 years without the consumption of spare parts. The plant is used daily and operates very satisfactorily according to the ship's owner.
