A system of Impressed Current Cathodic Protection (ICCP) is installed on each vessel and this is a method of corrosion protection which automatically controls the electrochemical corrosion of the ship’s hull below the waterline. This includes the external hull surface and the internal surfaces of tanks containing seawater, e.g. ballast tanks. What is Cathodic Protection?…
This post is going to be short and concise as the sea water system is quite simple and easy to operate. Sea water is used onboard vessel mainly for cooling purpose, but also for fresh water production and adjusting vessel trim and its stability. The sea water intake is possible through a crossover main pipe…
For a variety of reasons, ships rely on the seawater in which they move and one of the primary functions of seawater is to keep the engine and other sections of the ship cool while they are running. The utilized seawater is then discharged back into the sea, and additional seawater is taken in, resulting…
The fresh water generator is an equipment installed onboard vessels which is used to produce fresh water from sea water. There are two major ways of producing fresh water onboard vessels: vacuum evaporation and reverse osmosis, of which the vacuum evaporation comprises of two types: tube type and plate type. Each system has its own…
