Ensuring the proper operation of a ship's propulsion system necessitates the use of high-quality fuels. Several factors contribute to fuel quality, including the source of origin crude oil, refining methods, blending processes, and the quality of storage and distribution. Marine fuels must adhere to international standards such as ISO standar...

 Aluminium and silicon particles in fuel known as “cat fines” are catalytic residues from the refinery process. They can cause mechanical damage to fuel pumps, injectors, piston rings and cylinder liners. They are very hard and highly abrasive, thus causing abrasive wear to main engine components. These impurities in marine fuel mu...

 In south-western Mauritius besides the small village of Chamarel (Mauritius), you can find this uniqu land with colouring soil. The soil found here reflects seven different colours like red, blue, green, brown, violet, yellow and purple. The analysis of the soil was taken by x-ray fluorescence spectroscopy. The research show that this natural...
