Part-Load Optimisation Tuning Method Proves Popular

Part-load optimisation delivers significant fuel savings for MAN auxiliary engines


MAN Diesel & Turbo has announced that its Part-Load Optimisation initiative has rounded 180 orders since its introduction. Part-Load Optimisation is a tuning method that optimises fuel-oil consumption during the part-load operation of four-stroke, small-bore MAN auxiliary engines.


Finn Fjeldhøj – Head of Small-Bore, Four-Stroke Engineering – MAN Diesel & Turbo, said: “Part-Load Optimisation works on the principle that fuel consumption is reduced at low and part load at the expense of a higher fuel consumption in the high-load range, without exceeding the IMO NOx limit. We can deliver new engines pre-optimised, or retrofit as necessary. Both Part-Load Optimisation solutions have proved popular with the market to date, as evidenced by this strong demand.”


Part-Load Optimisation helps shipowners to maintain their auxiliary engines in good working order while reducing fuel-oil costs. It is recommended for GenSets that often run at part-loads below 75% MCR (especially the load range from approximately 40 - 65% MCR) and optimises engine performance at 60 - 65% MCR.


It is available for all new Holeby engines and can be retrofitted on all existing engines. The tailor-made retrofit kits cover all components, qualified service fitters and calculations of cost benefit; engine tuning can be executed with a charge-air blow-off valve or waste gate.


Part-Load Optimisation delivers fuel-oil savings of, typically, up to 5 g/kWh depending on engine type and load point, and improves the condition of key engine components due to its superior combustion process.


The same, relative fuel-consumption savings also apply when applied in combination with an SCR-system for IMO Tier III compliance.



References: Since its introduction, Part-Load Optimisation has won favour across a broad spectrum of shipping applications, especially medium- and long-range tankers, and feeder container vessels. The MAN L23/30H GenSet has proved a popular candidate for Part-Load Optimisation, typically @ 65% MCR using the charge-air blow-off valve tuning method.

Maritime Showcase in Shanghai - MAN Diesel & Turbo using Marintec 2017 to display emissions reduction technology and new engines


Marintec 2017 is one of the most prestigious events in the Asian shipping calendar and the 2017 edition is being held this week at the Shanghai New International Expo Centre in China. MAN Diesel & Turbo’s stand can be found in Hall N, Stand N1C41-2. Pride of place at the stand goes to models of the company’s new 45/60CR and ME-LGI engines, as well as its innovative HP-SCR emissions reduction technology. 


New Flagship

MAN recently revealed the successor to its 48/60CR engine in the company’s 4x line of high-performance diesel engines. The MAN 45/60CR marine diesel engine will initially be available as 12V and 14V versions that boast power outputs, of 15,600 and 18,200 kW respectively, with inline versions following at a later stage. 


Wayne Jones, Chief Sales Officer of MAN Diesel & Turbo, said: “The new engine combines the best features of the current 48/60CR, such as MAN’s common-rail system with ECOMAP capability, and adds new technologies such as two-stage turbocharging for an unrivaled Specific Fuel Oil Consumption. The resultant reduction in operating expenses and positive environmental impact are sure to attract strong market interest.”


High-Pressure SCR for Two-Stroke Engines

MAN Diesel & Turbo is using Marintec as an opportunity to bring further attention to its new high-pressure Selective Catalytic Reduction system. MAN SCR-HP is available for two-stroke engines of all bore sizes and reduces – through internal catalytic reaction – NOx exhaust emissions to IMO Tier III limits. With specially developed honeycombs and honeycomb materials, as well as an integrated mixing unit, the overall size of the reactor has been drastically reduced compared to typical market designs and its medium-speed counterpart. Delivery is first expected from the beginning of 2018.


Bjarne Foldager, Vice President MAN Diesel & Turbo and Head of Sales & Promotion Two-Stroke Business, said: “The development of our new SCR is an important step on the path to a more sustainable future of shipping and global trade. At the same time it offers additional choices to ship owners worldwide, who can now choose from all NOx reduction technologies and select the optimal solution for their MAN Diesel & Turbo two-stroke engines.”


ME-LGI concept

The MAN B&W ME-LGI dual-fuel engine expands MAN Diesel & Turbo’s dual-fuel portfolio, enabling the use of more sustainable, low-flash-point fuels such as methanol, ethanol, dimethyl-ether (DME) and Liquefied Petroleum Gas (LPG).


With the designation LGI (liquid gas injection), all existing MAN B&W ME/ME-C/ME-B engines are available for operation on low flashpoint liquid (LFL) fuels like methanol, ethanol, LPG and DME. The engines are operated as dual-fuel engines with high-pressure injection. These engines have the same fuel consumption as similar diesel engines, and the same tuning methods can be applied.

MAN Diesel & Turbo wins major order from the Kuwaiti oil and gas industry


With a double-digit million euro volume, MAN Diesel & Turbo has won an order for nine compressor trains for the state-owned Kuwait Oil Company (KOC). MAN technology will be deployed in Kuwait's Burgan field, one of the world's largest oil fields. The British plant manufacturer Petrofac has been contracted by KOC to build the Gas Gathering Center 32 here, enabling to process accompanying gases and to improve the quality of the oil produced.


Dr. Uwe Lauber, CEO of MAN Diesel & Turbo: "The oil- and gas-rich countries of the Arabian Gulf are an important focus region especially for our Turbomachinery business unit. With more than 50 compressors and turbines delivered to Kuwait alone, we are one of the leading providers of technology here." Across the Middle East, MAN Diesel & Turbo is able to look back on numerous projects with plant manufacturers (EPC), as well as with state-owned and international oil and gas producers.


In Kuwait, turbomachinery by MAN is also deployed in other gas gathering centers. "The current order is based not least on the positive experience that KOC has with us," explains Hassan Ajami, Regional Manager MAN Diesel & Turbo Middle East. The company’s technology is not only employed in upstream operations, as he stresses: "In the past year, we have booked an order for six ReTPac machinery trains for the Al Zour refinery in Kuwait."


The nine electric motor-driven compressors for Gas Gathering Center 32, type RB35 and RB28, will allow extremely challenging sour and wet gas from the Burgan field to be compressed. High proportions of hydrogen chloride and hydrogen sulfide mean demanding requirements for machines and materials. This current order also includes an option for additional machines and services.


"Just like with this order, the oil and gas industry is increasingly investing in the processing of accompanying gases, which until now have often been flared off," says Ulrich Mudrack, Vice President MAN Diesel & Turbo in Berlin, Germany. Sophisticated compressors, turbines and engines make it possible to make good use of such gases. "Processing and power generation benefit not only the customer, but also the environment, by reducing flaring and venting," Mudrack explains.
