18 months ago, the central IT department of the BMW Group began searching for a new CAD/CAM system. The goal was to find a CAD/CAM solution with a high level of coverage for the many different NC application areas in the specialist departments. In the autumn of 2014, the BMW Group invited OPEN MIND and five other CAD/CAM manufacturers to take part in benchmark tests, with OPEN MIND coming out on top thanks to the technical and economic benefits of hyperMILL, a modular CAM solution that integrates a comprehensive concept for 2D, 3D as well as 5axis milling/mill turning and machining operations like high-speed and high-performance cutting (HSC and HPC) in one interface. Complete machining with just one CAM software and one postprocessor for all turning and milling processes results in integrated processes and minimised machining times.
Finnish engineering company Wärtsila is to power the UK’s first dual-fuel ferries being built for Scotland-based Caledonian Maritime Assets (CMAL), the company said. Under the contract signed between the duo in December 2015, Wärtsila is also to supply extended engineering and site support services.
Wärtsila will supply each of the ships with two 6-cylinder main engines capable of operating on either LNG or conventional diesel fuels, two 6-cylinder auxiliary engines, horizontally offset gearboxes, shaft lines, seals and bearings, and controllable pitch propeller systems. The 102 metres long RO-RO ships are being built by Ferguson Marine Engineering Limited at a shipyard in Glasgow, and are scheduled to enter service during the second half of 2018 and will operate on various routes along the west coast of Scotland.
First dedicated turbocharger from ABB Turbocharging designed specifically for small bore medium-speed marine auxiliary diesel engine platforms with up to 2MW power output.
MXP has been designed to fulfil the specific needs of the marine auxiliary market in terms of operation, efficiency and maintenance. The dedicated technology enables optimum operation and performance for auxiliary engine applications, while the robust and yet simplistic design allows for easy maintenance, based on a self-service condition-based maintenance (CBM) model, which translates into lower maintenance costs for the end customer. Essential to the customer-centric design is the user-friendly maintenance concept of MXP that is supported with a digital self-service application, giving crew members the flexibility to independently maintain the turbocharger wherever and whenever necessary, using standard tools while the vessel is operational.
The MAN V35/44G TS is a superior efficient spark ignited two-stage turbocharged gas engine. The MAN V35/44G TS is available in 12V and 20V-cylinder versions with electrical outputs of 6,9 MW up to 12,4 MW. In single cycle applications, the MAN V35/44G TS reaches a mechanical efficiency up to 50.7%.
The two-stage version of the 35/44G TS grants additional power and efficiency, means a higher power density and hence a more compact plant design.
The idea behind two-stage turbocharging is simple: two turbochargers upstream from the engine, one after the other, which results in the significant increase in efficiency and output. For this concept, we use two strong in-house products: The continuous improvement of our well-known gas engines MAN 35/44G, combined with MAN designed and manufactured two-stage turbocharger unit.
The turbochargers are the core of this innovation and MAN Diesel & Turbo is the only large engine manufacturer that designs and builds its own turbochargers. This enables us to achieve the perfect matching of engine and turbochargers leading to the superior performance of the MAN 35/44G TS.
The tanker valued at 40.8 million euros, intended for the transport of chemical and oil products, is 184 metres long, 32.20 metres wide and has a load-bearing capacity of 49,500 metric tons. It is powered by a MAN B & W with a capacity of 8000 kW, which can reach the speed of 14.5 knots. The ribbon was cut by the owner and the Management Board member Danko Končar, who stated that the Trogir Maritime company was leasing these tankers to ship operators at a daily rate of between 7,500 and 9,500 dollars.
Federal Mogul has developed the cooling of pistons, which enables them to operate at an engine temperature more than 100°C higher than the current limit. Keri Westbrooke, Engineering and Technology Director at Federal Mogul, explains that this enables an increase of 5 % in energy efficiency. The company believes that it will start the mass production of such pistons by 2021.
