The market share of marine diesel engines is expected to grow rapidly owing to rising environmental awareness and increasing retrofit efforts. Various government measures to reduce marine pollution across the ECA may impact the demand for low-emission engines. Reductions in CO2 emissions and affordable prices in economically viable locations are some of the key factors driving product installations. The U.S. marine diesel industry is expected to grow significantly through 2027 as the situation normalizes. Rising import and export activities, and subsequent exploration efforts to meet expanding diesel demand, are likely to positively impact the industry outlook in 2021-2027. Worsening crude oil prices favor the deployment of diesel because of its higher efficiency compared to current alternatives.

MAN Energy Solutions has won an order for four dual-fuel MAN B&W 6S60ME-GI engines for the construction of two 8,000-lane-meter hybrid Ro-Ro vessels for CLdN. Each vessel will also be equipped with 2 × 6 MW electric propulsion motors, enabling the vessel to maintain a service speed of 16-17 knots in all-electric mode. The newbuildings will further reduce carbon intensity by 40% while meeting NOx Tier III standards. Human energy solutions. The ME-GI (-Gas Injection) engine sets a new industry standard for two-stroke propulsion engines on ro-ro, PCTC, container ships, bulk carriers, tankers and LNG carriers.

ME-Gi engines deliver the industry's lowest CO2 and methane leak emissions for LNG-fueled ships. The diesel principle ensures 100% reliable operation during gas load changes with only the normal amount of pilot oil added.

Nauticus Robotics Inc. has announced the initial production run of the Nauticus Fleet, a robotic navy of 20 pairs of Hydronaut - Aquanaut. These tandem pairs will be deployed in multiple offshore industries, serving applications ranging from subsea maintenance and intervention to data collection. The first robots will be delivered in the fourth quarter of 2022, and the rest will be delivered by the end of 2024.

'When it comes to low routine maintenance schedule, MAN L28/32 offers a great advantage with 20,000 hours between overhauls when operated on HFO. A low level of deformation and a low level of mechanical stresses (i.e. low wear-rates) are achieved through its sturdy engine structure and amply dimensioned running gear.'

Jugoturbina worked to satisfy its employees not only through working conditions but also to improve the living standards of all its employees and other citizens of Karlovac. Thus, during the years of its business, Jugoturbina organized various excursions and gatherings (Dance on Plitvice), opened a workers 'resort in Punat on Krlo, built a children's playground on Švarča, and organized workers' sports games in Karlovac.

Back in 1976, the first auxiliary engine under the SULZER license with the designation 12 ZV 40/48 was produced in Croatia, more precisely in the city on four rivers Karlovac, and in Karlovac there is still a company named Adriadiesel which is in charge of maintenance and supply of spare parts of that engine as well as all manufactured after it.

G-volution and SBL-Rail present dual fuel evolution concepts for Class 37, Class 59 and Class 66 locomotives. Dual fuel engines use compression ignition and burn two fuels simultaneously. This work shows how diesel fuel can be replaced by renewable net-zero carbon emissions fuels. The original diesel tanks were replaced with smaller ones and cylinders for biomethane or biopropane or hydrogen were installed. Compared to the original two-stroke EMD engine, the new four-stroke dual-fuel engine has a 10% reduction in fuel consumption. If a Diesel Particulate Filter (DPF) is installed, the engine will spend less time responding to the increase in back pressure when the DPF fills. Route simulations were completed using OTMRs provided by these locomotive operators in combination with dual fuel engines. 

The Wärtsilä 46TS-DF engine is the company's latest multi-fuel engine that can run on LNG, reducing air pollution, while also providing a viable basis for future decarbonization through biological or synthetic methane. According to the technology company, the engine was developed with a focus on economy, environmental performance and fuel flexibility, ushering in a new era of medium-speed marine engines. In April 2021, the Chantiers de l'Atlantique shipyard received the first order of this engine type from Royal Caribbean Cruises. The engines will be installed on the company's newest Oasis-class ship, Ocean Utopia. The vessel is currently under construction and will feature six Wärtsilä 46TS-DF engines with gas valve units and NOx reducers.
