THE NEED FOR A NEW CYLINDER OIL
The marine industry is adapting to legislation that is increasing operational complexity, and is under continuous pressure to lower its operating costs in the face of rising fuel prices and lower freight and charter rates. Many ship operators are looking to control costs through slow and ultra-slow steaming, reduced cylinder oil feed rates and extended maintenance intervals.
At Shell, we feel and understand the uncertain world our industry faces and we constantly innovate to develop solutions to help our customers weather these uncertain times. In response to the current challenges, we have remove complexity by providing a wide range cylinder oil, Shell Alexia S4.
CYLINDER OIL REINVENTED TO MEET YOUR NEEDS
In low-speed, two-stroke diesel engines, cylinder oil is exposed to thermal, insolubles, acid and humidity stress. These stresses degrade the oil and increase significantly under slow-steaming conditions because of the longer oil residence time in the cylinder. A reduction in engine load from 90% to 30% was found to cause a threefold increase in lubricant residence time.
Shell Alexia S4 is designed to combat all four types of oil stress under the widest range of operating conditions to help reduce costs and simplify operations. It has an SAE 40 viscosity grade that aids oil distribution inside the engine to improve the efficiency of the lubrication system, and a base number (BN) of 60, but can be used at the same feed rate as BN70 cylinder oils.
