Design and maintenance globe valve on ship Globe valve, a type of valve, is commonly used on board ships in places such as bilge suction lines. A linear motion valve, which regulates the flow of the fluid, the valve has a globe (bulbous) shaped body that houses the valve seat and the disc. The general […]
Gate valve on ships A variety of valves are used in the piping and machinery systems of the ship as per the need of the flow pattern of the liquid. All valves used on ships have the basic functionality of regulating the flow of the liquid in the pipes. Valves are used for almost all machinery systems […]
Sulphur Oxides air pollution from ships Causes and Effects of SOx Emission The sulphur oxides emission is due to the presence of sulphur compound in the marine fuels used in marine engines on board vessel. Better the grade, lower will be the sulphur content as it is removed by refining of the fuel. It has also […]
Marine diesel engine performance On ship, it is important to check the performance of the engine from time to time so as to ascertain working condition and fault finding. In earlier days, the performance of diesel engine was taken manually, but with the advancement of technology, automatic monitoring systems are being used. Types of Diesel […]
Achieve efficient combustion in marine engines Marine fuels used in ships are considered of the lowest grade as far as the quality is concerned. Massive engines of the ships consume thousands of litres of fuel each day. Because of such an enormous requirement of fuel, ships are forced to use low grade fuel oil, which […]
Marine scrubber application Classification of Marine Scrubbers On the basis of their operation, marine scrubbers can be classified into Wet and Dry scrubbers. Dry scrubbers employ solid lime as the alkaline scrubbing material which removes sulphur dioxide from exhaust gasses. Wet scrubbers use water which is sprayed into the exhaust gas for the same purpose. […]
Costs of scrubbers on ship What are the costs of scrubbers? Scrubbers are increasingly being fitted to newbuildings but the majority now in operation have been retrofits. The time for a retrofit is currently more than a typical scheduled drydocking meaning that extra lost earning days add to the capital outlay. The capital cost of […]
Scrubbers on ships really work Long before scrubbers or even before SOx was considered an issue for the shipping industry it was being regulated around the globe in connection with the use of large diesel engines in power production and other shore-based industries. As a consequence, exhaust gas cleaning or scrubbing technology is already a long […]
Open loop and closed loop scubber system for ship Classification of Marine Scrubbers On the basis of their operation, marine scrubbers can be classified into Wet and Dry scrubbers. Dry scrubbers employ solid lime as the alkaline scrubbing material which removes sulphur dioxide from exhaust gasses. Wet scrubbers use water which is sprayed into the […]
A guide to scrubber system on ship Scrubbers or Exhaust Gas Cleaning Systems (EGCS) are used to remove particulate matter and harmful components, such as sulphur oxides (SOx) and nitrogen oxides (NOx) from the exhaust gasses generated as a result of combustion processes in marine engines, to implement pollution control. These scrubbing systems have been developed and employed […]
