In February this year Pronomar received an order from Royal Boskalis Westminster NV, a Dutch company that provides services in maritime sectors on international basis.
Royal Boskalis Westminster NV decided to place an order for the Merus rings for their trailing suction hopper dredger, the ‘Prins der Nederlanden’. The Merus rings are a highly innovative, environment-friendly solution for green water treatment. The fact that Royal Boskalis Westminster NV placed this order shows that they care about the state of their technical, water-related equipment. For that reason they ordered the Merus rings, which counteracts scaling.
The following rings were installed:
- 1 x 2” HCI BIO ring (for the hydrofor)
- 1 x 1½” HCI BIO ring (for warm water)
- 1 x 1½” HCI ring (for the hydrofor – technical water)
- 1 x 4” HCI ring (for Alfa Laval fresh water generator).
Once the Merus rings are installed, they give off tiny oscillations that disturb the lime scale. Afterwards the troublesome substances are simply flushed away. By keeping the equipment free from scaling the initial performance level of the equipment will be braught back, plus prolonging the lifetime of the equipment, which in return means a significant decrease in costs.
Shortly after, Royal Boskalis Westminster NV has given feedback and has confirmed that the Prins der Nederlanden has less problems with the Alfa Laval fresh water generator and with the technical water on board of this vessel.
