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]

Universal oils are not unrestricted usable

At slow steaming cold corrosion can occur – Castrol sees concerns by specifications given from the engine manufacturers confirmed. Many shipping owners go for slow steaming. But to avoid long term damages by slow steaming particular adjustments must be done. One aspect is the use of optimized lubricating oils. A possible problem is cold corrosion. The lubricating oil manufacturer, e.g., Castrol Marine assumes that, during slow steaming, cold corrosion can happen if lube oils with lower base numbers (BN) come together with fuels with higher sulphur content. “We always point out that oils with lower BN are unsuitable for slow steaming with modern diesel engines. Both market leading OEM’s have now created specific guide lines, which go along with our experiences”, says Castrol manager Paul Harrold. They recommend their customers to coordinate the use of lube oils with engine type and working conditions. Last May Castrol presented some case studies. These figures un... [More]

The S3 switch (a marketing acronym for ‘Smart Sulphur Switch) is a prototype developed by Denmark’s Insatech in cooperation with O.W. Bunkers, to blend and adjust two fuels (HFO and MDO) to a desired sulphur content enabling monitoring and control of marine diesel engine exhaust gas emissions without fitting expensive scrubber units.  The S3 is presently on trial aboard ships belonging to some of this major bunker supplier’s customers in Northern European waters, and commercial production is planned for later this year. S3 Fuel Switch Skid: Image credit Insatech Fuel Switching and BlendingOn most modern ships two service tanks are provided: one service tank contains the higher sulphur fuel oil and the other may contain low sulphur fuel to ensure MARPOL Annex VI emission regulations are met. This arrangement will involve a fuel changeover at some point during the ship’s engine operation, normally achieved by means of a three-way valve, and it is at this poin... [More]

Is methanol the future of maritime fuels?

It’s not a secret anymore that the shipping industry today is facing some serious challenges with respect to meeting upcoming exhaust gas emissions regulations. The contribution from shipping to sulphur oxide (SOx) and nitrogen oxide (NOx) emissions today is considerable, thus the need for reductions. Three main alternatives – switching to low-sulphur fuels, installing exhaust after-treatment devices, e.g. scrubbers, or using natural gas – have been investigated to some extent, but very little information is available on methanol as a marine fuel.Methanol is a clean fuelMethanol does not contain sulphur. Emissions of particulate matter and NOx from methanol combustion in marine engines are expected to be lower than those resulting from the combustion of conventional fuels. Methanol is widely available, can be safely transported and distributed using existing infrastructure, and in 2012 it is currently much cheaper than marine distillate fuel based on energy content.

A new dual-fuel marine diesel engine variant from MAN Diesel & Turbo, the ME-LGI,  runs on liquid gas fuels – methanol, LPG, dimethyl ether (DME), and (bio-) ethanol as well as other, low-flash-point fuels – building on the manufacturer’s successful LNG /HFO dual-fuel ME-GI low speed engine plant introduced last year. MAN developed the ME-LGI engine in response to interest from the shipping world in using alternatives to heavy fuel oil. Methanol and LPG carriers have already operated at sea for many years and many more LPG tankers are currently being built as the global LPG infrastructure grows; in themselves a ready market once a suitable dual-fuel engine became available.Sure enough,  the new engine, unveiled on 1, July 2013 was snapped up as MAN signed a Letter of Intent with Vancouver-based Waterfront Shipping for the installation of four MAN ME-LGI engines which will run on a blend of 95% methanol and 5% diesel fuel.

Liquefied Natural Gas (LNG) as engine fuel?

Filed Under: Fuels & Lubes, LNG fuel
To be honest: being a Graduated Engineer for Ship Operation Technology of the “old school” and for around 18 years up to now a specialized shipping journalist with a particular focus on combustion engines, I’m pretty much, let me say it politely: confused!  Wherever you read an article about gas fuelled engines everybody speaks about LNG-fuelled engines! Lately I read an article in the pretty much well-known daily German newspaper THB (Täglicher Hafenbericht=Daily Port Report) where the following is mentioned: “…Both ferries (Stavangerfjord and Bergensfjord) will be driven solely with liquefied gas (LNG) instead with heavy fuel”. But is this correct? Most important question: what is LNG and why do we have LNG? Natural gas (NG) is a mixture of different gases consisting primarily of methane. The higher the methane content (more than 90%) the better. Because the high methane number (MN) influences positively the combustion process. It is usu... [More]

DNV (Det Norske Veritas) classification society now offers shipowners the support they need to make newbuilds and existing vessels ‘LNG ready’ with class approved designs, ready for later, simple retrofit of LNG technology. The service enables shipowners to make smart choices and minimal investments now in readiness for when LNG bunkering becomes widely available.  Shipowners are supported through all stages of the decision-making process as they prepare to meet the IMO air emission regulations entering into force from 2015. There are three obvious technology options for meeting Emission Control Area (ECA) requirements: installing a scrubber, switching to low sulphur fuel oil or to go for LNG as fuel and installing gas engines. Alternative fuels such as methanol and biofuels are also being developed.  “Each option has different uncertainties, for example the relative immaturity of some technologies and the effect market forces will have on the price of the d...
