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, on a small scale, has proven that this problem can be solved. A field trial is now planned, aimed at testing the suitability on a large ship in practice. We are seeking partners interested in such a test and wishing to gather experience with us.
