On third of September the second inland navigation tanker, which is also powered by natural gas, has been christened by the President of the Central Commission for the Navigation of the Rhine, Ms Belliard, in Rotterdam. The launch of the GreenRhine tanker took place at the Port of Rotterdam in the presence of representatives from the Dutch and European inland navigation sectors, local and regional authorities, suppliers, Interstream Barging (from whom Shell has chartered the ship) and Peters Shipyards, the company that built the ship. The sister ship GREENSTREAM is absolutely equivalent to the newbuild GREEN RHINE The GreenRhine is the second of two gas-electrically inland navigation tankers that Shell is chartering for the transport of mineral products on the Rhine. The GreenRhine is absolutely equal to the first natural gas powered vessel Greenstream. They feature many innovations in the fields of safety and energy efficiency. For example, rather than a single large engine like trad... [More]

Oil Stress Analysis Gave Key to Shell’s Unique New Lube Oil

No need to keep different multiple spec lube oils on board any longer say Shell Marine Products as they launched their lube oil, Alexia S4 a few days ago. Their new oil is a ‘one-stop’ solution lube for all climates, all seasons, in a wide range of vessel types with low-speed two-stroke engines, including those steaming at slow and ultra-slow engine speeds. As if that were not enough, Shell also say that the new formulation better protects engines. VLCC: Photo courtesy of Shell Fundamentally though, the introduction of this oil for low-speed, two-stroke marine diesels was founded upon a breakthrough in the understanding of oil stress in this type of  engine, as will be seen.Lube Oil Stress in Slow-speed Marine DieselsOil stress, the single most important factor that governs the lifetime and performance of an engine lubricant, is the name given to those factors which degrade lubricants, making them less effective. Research on oil stress has been done for many years ... [More]
