WinGD Debuts On-Engine SCR
WinGD will be deploying its on-engine NOx reduction solution ed for the first time on commercial engines after securing type approval.The integrated Selective Catalytic Reduction (iSCR) solution was tested at Mitsui E&S DU (MESDU) Co’s factory in Aioi, Japan, where three WinGD 5X52-S2.0 engines are being built for bulk carriers under construction at a Japanese shipyard.The type approval follows more than two years of service experience with a prototype version. The latest iteration features reduced material and production costs…
MAN’s Full-Scale Ammonia Engine Runs at 100% Load
MAN Energy Solutions has reported that its ME-LGIA (Liquid Gas Injection Ammonia) engine, currently undergoing testing at its Research Centre Copenhagen facility, has run at 100% engine load for the first time.Ole Pyndt Hansen, Head of Two-Stroke Research & Development, MAN Energy Solutions, said: “We began full-scale testing in November 2024 and have since proceeded in a cautious and safety-first way. We have now operated the engine on ammonia from 25–100% load, marking yet another important step forward in the maritime energy transition.
Engine Room Fire Sparks Request for New IMO Requirements
The UK Marine Accident Investigation Branch (MAIB) has released its report into the engine room fire on board ro-ro passenger ferry Stena Europe as it approached Fishguard, Wales.At 2115 on 11 February 2023, a fire broke out in the engine room of the vessel while on passage from Rosslare, Ireland, to Fishguard, Wales. The fire caused significant damage to the engine room but nobody was injured and there was no damage to the environment. The fire was extinguished by the crew.The…
Basic Design Completed for Conversion of Old LNG Carriers
NYK Line, Namura Shipbuilding and Sasebo Heavy Industries are collaborating to replace the main propulsion on steam turbine driven Moss-type LNG carriers to dual-fuel diesel engines and have now completed the basic design step.In October 2023, NYK was granted Approval in Principle (AiP) from ClassNK for the concept, and the three companies will now proceed with a detailed design.The aim is to improve environmental performance, make efficient use of existing vessels and contribute…
ORNL, Caterpillar Collaborate on Methanol as Fuel for Marine Engines
A collaboration between Oak Ridge National Laboratory (ORNL) and Caterpillar Inc. will investigate using methanol as an alternative fuel source for marine vessels.Members of the research team kicked off the project with the installation of a 6-cylinder engine at the Department of Energy’s National Transportation Research Center at ORNL.The ORNL and Caterpillar collaboration focuses on a four-stroke internal combustion marine engine that will be modified to run on methanol.Although methanol has many advantages, it is more difficult to ignite than diesel.
MAN Provides Gensets for Hybrid Cable-Laying Vessel
Shipbuilder and designer VARD has ordered 4 × MAN 12V175D-MEM gensets in connection with the building of a new purpose-built, cable-laying vessel (CLV) for Danish subsea specialit NCT Offshore.The gensets will form part of the vessel’s diesel-electric DP2 propulsion system, which also includes a hybrid battery package.The high-speed 175D gensets will each come accompanied by compact MAN selective catalytic reduction systems. Furthermore, MAN Energy Solutions states that the engines…
WinGD Wins First AiP for Ammonia Two-Stroke Engine
WinGD has secured the first ever approval in principle (AiP) for two‑stroke engines fuelled with ammonia.Lloyd’s Register awarded the AiP to WinGD’s X-DF-A dual-fuel range, and WinGD says this gives shipowners the assurances they need to realise vessel designs using ammonia-fuelled main engines. The first engine to be developed, the 52-bore X52DF-A, will be available for delivery from Q4 2024 and is applicable to a range of vessels including gas and bulk carriers.WinGD was able…
J-ENG Opens Customer Support Center in China
Japan Engine Corporation (J-ENG) has opened a customer support center in Shanghai, China.The center aims to strengthen after-sales service for vessels equipped with UE engines in China as well as providing further support for Chinese UE licensees.J-ENG has been strongly promoting global expansion and is focused on expanding the market share of its UE engines in China. Increased orders in China have established the foundation for continuous production for the engines. Chinese UE licensees have received orders for 184 units, mainly for Chinese coastal vessels (i.e.
WinGD Enhances Fuel-Flexible Efficiency with Variable Compression Ratio
Swiss marine power company WinGD has introduced a core engine technology that eliminates the need for ship operators to compromise on optimal combustion when using multiple fuels.Variable Compression Ratio (VCR), jointly developed with Mitsui E&S DU Co (MESDU), will be installed on a vessel powered by an X62DF engine and then rolled out across selected engines of the X-DF engine portfolio.An engine’s compression ratio is usually a fixed parameter, playing a direct role in power and fuel efficiency.
SCR Retrofit Enables Cruise Ship to be Tier III Compliant
MAN Energy Solutions’ after-sales division, MAN PrimeServ, has completed a retrofit aboard the Ambience, a vessel belonging to Ambassador Cruise lines, managed by Bernhard Schulte Cruise Services.The scope of the project covered the installation of Selective Catalytic Reduction (SCR) systems, while two of the ship’s four MAN 8L58/64 engines replaced their NA57/T turbochargers with modern MAN TCA 66 units.The order came about when Ambassador took over Ambience with the intention…
MHI-MME Celebrates 20th Anniversary of MET Turbocharger License with HHI
Mitsubishi Heavy Industries’ machinery company (MHI-MME) has presented Hyundai Heavy Industries (HHI) with a model of an MET turbocharger rotor to celebrate the companies' 20th licence anniversary.HHI has been the world’s largest manufacturer of marine engines since it produced its first 2-stroke diesel marine engine in 1979. Today, its engine division, based in Ulsan, manufactures a large number of diesel engines for major ship builders in South Korea and China. Many of those diesel engines are equipped with MET turbochargers…
