The diffuser plate is attached to the tube with help of chains. In addition a wire outside the tube connects the diffuser plate with the pump house. The main function of the diffuser plate is to prevent damaged on the sediments at the sea bottom by the vertical flow from the pump. At the same time, the diffuser will distribute the oxygen-rich water around the tube.
Necessary equipment for operation during demonstration period
The design of the prototype includes the possibility to adjust the pumping and flow rate in order to investigate effects of pumping on the Kanholmsfjärden system. This requires the monitoring of the pumping effect and the pump itself. Therefore, the prototype is equipped with a flow meter inside the tube that provides current flows for various pumping conditions.
As the pump is driven with electricity a sea cable that goes from the pump to a connection at the land side will be installed. This requires some technical equipment such as safety switches, frequency converter, fuses etc.
For safety reasons the prototype is further equipped with both GPS and AIS systems as well as various seamarks which identify the approximate position of the pilot. This marking consists of both special marks and lights attached to the prototype.
