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.
The construction and production of large steam turbines, diesel engines and centrifugal pumps is a technical, technological and scientific challenge that only large or developed countries can afford, such as Yugoslavia in 1949, 1954 and later was not. This means that the effort, enthusiasm and knowledge of the employed engineers and technicians was significantly above the Yugoslavia's average.
In order to construct a steam turbine, it is necessary to know the calculations of thermodynamics, material strength, theory...
Various experts participated in the development of turbines, engines, laboratories, for example: prof. Ernest Kraft, A. Ošlag, J. Bašić, S. Todorovski, prof. M. Mikulić, ing. I. Gojak, ing. I. Tudić...
'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.
