You can rely on Shell Alexia in a changing world. The marine industry is changing rapidly. In just 16 years, the drive to reduce fuel costs and improve environmental performance has seen maximum container-ship capacity increase from about 7,000 twenty-foot equivalent units (TEU) to 18,000 TEU. These new vessels are powered, at slow steaming speeds, by super-long-stroke engines that present a new set of cylinder oil challenges, including cold corrosion. At the same time, tough environmentally driven legislation is increasing operational complexity.
