As described in our previous news item, InnoVfoam supplied a compact proportioning skid for the pipelaying vessel ‘’Aegir’’. In this article we will tell you more about the details and operation of the skid.
A flow capacity of 3.900 l/min will go through the 6”water inlet. The main flow is created by the existing pump on the ship and reduced to a fixed flow by means of an Inbal pressure reducing valve.
In the skid, 3% foam concentrate will be added to the main flow. The foam concentrate is added by means of a ‘’Wide range Balanced Pressure Proportioner'' (MBWP) and an electrically driven foam concentrate pump (for moving foam concentrate from the foam tank to the proportioner). The water + foam concentrate mixture (premix) is streamingthrough the three outlets of the skid which are connected to the 3 electric fire monitors on the helideck.
The skid is built as a completely closed, insulated and heated unit. Shutters on two sides of the skid make the internal part optimal attainable for maintenance and testing.
