Aquality systems for twelve MAN engines will manage cooling water quality on the 'Heerema Sleipnir'

Dutch waste and water system specialist Aquality has supplied Sembcorp Marine with eight automatic cooling water treatment systems for the semi-submersible crane vessel ‘Heerema Sleipnir’.

The unit will continuously control and monitor the water quality of both low-temperature and high-temperature cooling water circuits of the vessel’s twelve MAN engines.

The tailor-made systems will perform nitrite free water treatment, checking water quality by use of product concentration meters (refractometers) as well as pH and conductivity measuring units. Based on these measurements the treatment products are being injected, trend analyses will be performed alarms generated.

In each engine room, holding three engines, one unit each for low-temperature and high-temperature cooling water will be installed. These systems monitor the running engines in a programmable cycle.
