Marine diesel engines

Marine diesel engines are very large assemblies which generate a great deal of heat during operation. Frequently, these engines are cooled directly with seawater. Seawater also contains calcium carbonate. This calcium carbonate is deposited, together with other seawater constituents, in the cooling circuit of the engines. This impairs cooling of the engines and consequently, the engines can no longer be operated at full output so as to avoid overheating. For this reason, the engines must be cleaned chemically at regular intervals in order to ensure optimum cooling again.

Merus has proven at several diesel engines, either on ships or on offshore platforms,  where seawater direct is used for the cooling of the machines, the problem of scaling and corrosion can be reliable solved. See as well the case study offshore platform.

In addition the barnacle and other sealife which is passing the filters are treated as well. It can be seen in several applications, there are far less or no barnacle able to settle in the system and start growing. This has been done and proofed in either onshore applications, where seawater is used for cooling purposes in plants, or offshore on cooling facilites on offshore platforms or even on ships.

The picture above shows the dissasembled sea water filter. It can be easily seen, there is no scale at all left on the filter. The corrosion, which is normally a big problem has entirely stopped.

The picture to the right shows the sight glass of the assembled filter. Before a few weeks after cleaning the filter, you could not see through the sight glas. Now with Merus the sight glas is almost clean and it can be looked through.
