Dual-Fuel Variant of MAN L23/30 Engine Awarded TAT – Pressemeldung: Dual-Fuel-Variante des MAN L23/30 wurde TAT erteilt

MAN Diesel & Turbo’s dual-fuel MAN L23/30DF engine successfully passed its Type Approval Test (TAT) on November 2nd 2017 at CSSC Marine Power (CMP) in Zhenjiang in front of the industry’s main classification societies. The five-cylinder test engine in China had an output of 125 kW per cylinder at a nominal speed of 720/750 rpm.

Finn Fjeldhøj – Head of Small-Bore, Four-Stroke Engineering – MAN Diesel & Turbo, expressed the company’s high expectations for the engine and said: “The L23/30DF covers a power range of 625 – 1,200kW, which makes it particularly attractive for such ocean-going vessels as bulkers of most sizes, general cargo ships, chemical tankers, and smaller LNG-carriers, as well as ships operating in ports and near the coast. Encouragingly, shipowners around the world have already shown significant interest in the engine and we are very optimistic about its future prospects.”

The TAT included tests of the engine’s:

- SaCoSone alarm and safety system

- dual-fuel safety concept, including a test of the pilot-fuel system

- load-step performance;

- and a components inspection.

The MAN L23/30DF engine was also granted a certificate for compliance with IMO Tier III regulations in gas mode without any after-treatment equipment. In addition, the engine can provide up to 110% power output in both gas and fuel modes.

ESL Shipping, the leading carrier of dry-bulk cargoes in the Baltic region, has already ordered the first six L23/30DF GenSets for two 25,000-dwt cargo carrier newbuildings, currently under construction at CSC Jinling ship yard in China.

WinGD X-DF Engines Power CMA CGM’s Record Containerships

As the latest high point in an unbroken run of prestige contracts for its low-speed X-DF dual-fuel engines with low-pressure gas admission, Winterthur Gas & Diesel Ltd (WinGD) is pleased to announce that French shipping line CMA CGM, based in Marseille, has chosen WinGD’s largest, 92 cm bore, dual-fuel low-speed engine to power what are presently the largest containerships ever ordered.

The 12-cylinder X92DF engines (12X92DF) will power a series of nine “mega” containerships, each with a record capacity of 22,000 TEU. The vessels ordered by CMA CGM will be built at the yards of Hudong-Zhonghua Shipbuilding (Group) Co., Ltd. and Shanghai Waigaoqiao Shipbuilding Co., Ltd. They are due to enter service in 2020 on routes between Asia and Europe and are designed to have the potential to sail complete Asia-to-Europe voyages on liquefied natural gas (LNG). The 12X92DF engines will be rated 63,840 kW at 80 rpm, making them the most powerful gas and dual-fuel engines ever built.

Beyond leveraging the operating economy and reliability of WinGD’s X-DF engines, with this futuristic move CMA CGM is endorsing the outstanding performance of WinGD’s dual-fuel engines with low-pressure gas admission as a way of addressing existing and upcoming regulations from the International Maritime Organization. “Given the low NOx emissions of dual-fuel engines using lean burn combustion and the extremely low sulphur content of natural gas, by choosing our X-DF engines and LNG, CMA CGM is automatically complying with all existing and future emissions regulations,” says Volkmar Galke, General Manager of Sales at WinGD.

For CMA CGM, Ludovic Gerard, Vice President of Owned Fleet comments: “With this move to LNG energy, CMA CGM is moving ahead for a greener shipping. We selected WinGD engines for the main propulsion on the grounds of their experience in dual-fuel engines and our positive feedback on the two-stroke Generation X engines”.

The regulations already met by the WinGD X-DF dual-fuel engines include the Iimits on NOx in Emission Control Areas (ECAs) imposed by IMO Tier III and the 0.5% limit on sulphur in fuel which will be introduced in 2020, as well as possible limits on particulates. “The built-in efficiency of our lean-burn dual-fuel engines is also complemented by the favourable ratio of carbon-to-hydrogen in methane - the main constituent of natural gas - which mean that our X-DF engines are already low emitters of CO2 compared to liquid fuelled engines,” Galke continues. “Our X-DF engines are thus an excellent starting point for playing a full part in achieving the 30% improvement in overall vessel efficiency up to 2025 specified by the IMO’s Energy Efficiency Design Index (EEDI).”

Looking at the overall Total Cost of Ownership (TCO) of the new vessels, as well as operating expenditure (OPEX), capital expenditure (CAPEX) is also reduced because the emissions levels of WinGD X-DF engines are achieved without the need to install exhaust gas after treatment systems, and by the application of the low-pressure gas admission feature of the X-DF engines, which uses less expensive, more energy-efficient gaseous fuel compression equipment compared with low-speed dual-fuel engines requiring high pressure gas injection. In addition, WinGD’s Generation X engines feature a series of designed-in measures which target increased ease-of-maintenance. It is these aspects that have helped WinGD substantially increase its market share since the introduction of its new diesel and dual-fuel engines. WinGD has so far received more than 75 orders for X-DF engines since their introduction to the market at the end of 2013. Besides being popular for application in LNG carriers for main propulsion, the number of orders received for cargo ships operating on LNG has increased substantially in 2017, with over 25 engine orders received in the year to date.
