Schiffstechnik | Ship Technology MAERSK FLUID TECHNOLOGY Blending-on-Board Value Calculator updated Maersk Fluid Technology (MFT) have upgraded the SEA-Mate Blending-on-Board Value Calculator to include a mobile optimised version that will assist in calculating savings, based on a variety of real life scenarios. The SEA-Mate Blending-on-Board (BOB) system enables the crew on board the vessel to blend an engine-specific fitfor-purpose cylinder lubricant with the optimal neutralisation and detergent properties. The in-use 2-stroke engine system oil is blended with a high-BN cylinder oil. The resulting fit-for-purpose cylinder lubricant composition matches actual engine operating conditions and fuel sulphur levels, making it possible to reduce cylinder oil consumption and mitigate issues like cold corrosion and excessive cylinder wear. Under traditional running conditions, no regular consumption of a 2-stroke engine’s system oil takes place. Its additives are depleted and viscosity increases over time. As BOB generates a consumption of the in-use system oil, the crank case oil is replenished with fresh oil with fresh anti-wear & detergent additives etc. And as the refreshment becomes a reoccurring event, system oil viscosity is returned to its original state, reducing friction in the engine and thereby providing proven fuel savings up to 1.5%. The Blending-on-Board Value Calculator allows customers to evaluate the different potential savings with their engine and running conditions in mind, and a vessel-specific savings potential report is generated. The report highlights potential cylinder oil savings, as well as energy and consumption savings related to having a continuous refreshment of the system oil. Calculations are on actual system and cylinder oil consumption & cost for both main engine and auxiliary engines. It also includes an estimate for expected reduction of maintenance cost – reduced cost for change of cylinder piston rings & liners, reduced cost for purifier maintenance and more. The resulting report is emailed to your inbox for further evaluation and support when building a business case. Sune Lilbaek, Head of Sales at Maersk Fluid Technology, explains: »By using the value calculator it is easy to see the potential cost savings achievable with the introduction of a BOB system. With over SEA-Mate Blending-on-Board Value Calculator 200 installations to date, we have proven it is possible to achieve lubrication at, or close to, the lowest allowed consumption of lubricant as specified by the engine manufacturer. This results in proven reductions of up to 40% in 2-stroke engine cylinder oil consumption, as well as significant fuel and maintenance savings.« M Photo: Maersk Fluid Technology THORDON BEARINGS Water lubricated shafts benefit ocean sustainability There is no doubt about oil-lubricated propeller shaft systems damaging the marine environment. At the World Ocean Council’s fourth Sustainable Ocean Summit SOS16, Thordon Bearings’ Director of Marketing and Customer Service, Craig Carter, explained that the fleet of 45,000 ocean-going vessels that continue to operate oil-lubricated shaft bearings are estimated to be leaking the equivalent of five Exxon Valdez oil spills into the ocean year-on year. Acknowledging the raft of environmental challenges shipowners are already faced with, he said that the shipping industry must decide whether ocean sustainability can really be achieved with the continued use of a system that discharges between 130 mill. and 244 mill. l of operational oil into the ocean environment every year. Carter said: »Shipowners have a decision to make – continue to use oil systems that have the potential to pollute and may not Water lubricated bearings – a way to comply with future regulations? Photo: Thordon Bearings meet pollution regulations or return to seawater lubrication. Since we started installing seawater lubricated bearing systems in the early 1990s, we have prevented over 62 mill. l of oil being discharged into our oceans. A seawater lubricated propeller shaft bearing system is the only system that guarantees compliance with all pollution regulations and has zero impact on environment.« Carter informed World Ocean Council members about the history of the water-lubricated stern tube bearing system, a technology that has come on leaps and bounds from the problematic days of Lignum Vitae bearings and stuffng boxes. »Polymer materials and bearing designs have advanced to ensure long life performance with very low operating costs. All of the major classification societies have now revised their shaft withdrawal and inspection regimes due to the new technology allowing full monitoring of a seawater system. The technology now offers the technical equivalent of an oil lubricated stern tube but without the risk of pollution and associated fines. Shipowners now have a viable, cost-effective option.« M 76 HANSA International Maritime Journal – 154. Jahrgang – 2017 – Nr. 2

NOVVI Chevron invests in renewable base oil technology Chevron has made an equity investment into Novvi, a joint venture of Amyris, Cosan and American Refining Group (ARG). Terms of the transaction were not disclosed. Novvi is the market leader in renewable oils and produces targeted hydrocarbon molecules from plant sugar for automotive, industrial, marine, and construction applications at unbeatable economics. The company’s products and technology are recognized by the global lubricant market to deliver sustainable, high-performance solutions in a range of lubricant applications. Since launching first commercial production in 2014, Novvi has been steadily increasing base oil manufacturing to keep up with robust and growing demand for a variety of applications. Lubrication News Schiffstechnik | Ship Technology In addition to an equity investment, Chevron and Novvi plan to work together to introduce new base oils and lubricants to the industry in key areas. Chevron is a manufacturer of base oils and one of the world’s largest suppliers of finished lubricants. Chevron has one the world’s largest base oil manufacturing platforms through its own refining network and its base oil licensing technology position. »We are very pleased that Chevron has decided to invest in Novvi. Chevron’s investment is a further validation of the market acceptance that Novvi and its technology have gained,« stated Jeff Brown, Novvi LLC’s CEO. »The investment in Novvi will provide us with access to high-performance renewable base oils, which is strategically aligned with our aggressive growth plan, particularly in the synthetic and renewable lubricants space,« Brent Lok, Manager of Chevron Base Oils Marketing and Business Development, explained the move. »Novvi’s technology creates new possibilities for longer-term product development within Chevron,« he added. M LIQUI MOLY All-purpose additive for diesel engines Liqui Moly’s »Marine Diesel Protect« has been given an additional function. The additive now not only combats bacteria, cleans the fuel system, provides anti-corrosion protection and increases the cetane number, it also protects the fuel more effectively from oxidation and ageing so as to avoid problems that occur after long periods of disuse. »Marine Diesel Protect is a versatile all-purpose solution that can be used preventively or to tackle an existing problem,« says Jan Volk, who is in charge of the marine trade at Liqui Moly. »If you have the additive on board, you’re well equipped to deal with all the typical diesel problems.« One of these is the ageing of diesel fuel. This tends to occur in boats that are out of service for lengthier periods or are not moved very much. The chemical composition of the diesel fuel changes over time. Resin-like residues can form which block the nozzles and filters. The new Marine Diesel Protect formula slows down the ageing process of diesel fuel and protects it from harmful oxidation. Marine Diesel Protect also provides protection from microbial contamination. Bacteria, yeasts and moulds spread during periods of disuse, forming a tough slime that blocks the fuel filter, forcing the engine to stall. Marine Diesel Protect combats these microorganisms. The additive also removes deposits from the entire fuel system and ensures effective protection from corrosion. Finally, it contains a cetane number improver that makes the fuel more combustible. »Our Marine Diesel Protect is the chemical Swiss army knife for all those who own a boat with a diesel engine«, Jan Volk puts it.
