TECH-INNOVATION POWERED BY VDMA - MARINE EQUIPMENT AND SYSTEMS MAN ENGINES | HEINZMANN Stationary gas engines set for marine use The Dutch shipyard Concordia Damen will build 40 new inland water vessels of type Parsifal by the end of 2024. MAN Engines is suppling this project with 80 MAN E3262 gas engines. The twelve-cylinder engines will be installed in gensets from the Dutch partner MAN Rollo. In combination with electric generators, two of these gas engines, which together deliver 990 ekW of power, form the gaselectric propulsion system for each of the low-emission tankers. The gas engines are powered by liquefied natural gas. The LNG is first converted back into a gaseous state by air-conditioning evaporators so it can be used as fuel in MAN gas engines. For the Parsifal project, MAN Engines is supplying a certified gas engine and engine control system that has been approved according to the latest, stringent EU Stage V inland waterways emissions regulations. This came into effect in 2020 and applies to the entire European market. »Blue Marjan« is the first tanker in the fleet of 40 vessels to be launched The marine-certified engine control system from German company Heinzmann was adapted and fine-tuned to the specifics of the application so that the emission limits could be adhered to both reliably and sustainably, and the stringent operational specifications could also be met, MAN says. © MAN Rollo HJS Exhaust systems enable compliance with the lowest emission requirements To meet the increasingly stringent emission requirements in inland shipping, HJS offers tailor-made solutions for retrofitting existing units. The company has specialised in reducing diesel engine emissions for more than 45 years. Based on this expertise, the The systems is reducing particulates and nitrogen oxides © HJS company says it has developed a flexible modular technology system that enables individual emission upgrades, even in small quantities, right down to singleunit applications. Self-sufficient exhaust systems based on the SCRT architecture are used. According to the company, this means »state-of-the-art« exhaust technology for reducing particulates and nitrogen oxides, just like original equipment, without having to intervene in the engine. HJS supports customers from the design and technical implementation to the acceptance and approval of the system. The Stage V Emission Upgrades have now also been specifically adapted to the engine package of inland waterway vessels. HJS follows a »plug & play« approach based on adapted hardware and control modules from the large-scale production environment. This approach is intended to reduce the scope of investment. Thanks to this principle, it is also possible to equip a wide variety of applications with either constant or variable speed. According to HJS, this makes it possible to use the system in applications ranging from generators and construction machinery to railways and ships. The system does not require compressed air assistance. This means that there may be no need to invest in an air compressor. 64 HANSA – International Maritime Journal 04 | 2022

BACHMANN ELECTRONIC Relief on the bridge Körting ejectors for the shipbuilding industry © Bachmann Different OpenBridge styles In the search for optimized solutions, fleet operators often turn to systems from multiple suppliers, many of which offer only proprietary interfaces, the Austrian company Bachmann says. For modern ship bridges, this »can lead to inefficient, difficult-to-use, and error-prone designs«. Bachmann electronic teamed up with the OpenBridge design consortium to provide the solution. For open-source design framework OpenBridge, the goal is to standardize system integration on a ship’s bridge. It facilitates the development of safe and efficient workspaces, including seamless design and integrated technical systems, fully compliant with international shipbuilding regulations. Building on software elements designed by OpenBridge, Bachmann’s visualization solution Atvise provides users with a flexible, configurable system. The same look and feel across the working environment of an entire fleet should make the crew‘s work on the bridge easier. With a standardized framework, interfaces could also be optimized to user needs. Tailored design A typical OpenBridge screen stands out due to the clarity of information on display. Personalized displays can be created quickly and easily due to the wealth of information available. For this purpose, a wide range of OpenBridge elements have been implemented in Atvise builder. These building blocks include main engine data, rudder position, azimuth, thruster, as well as various other display and control elements. The OpenBridge interface offers four brightness levels, ensuring optimal visibility at all times. Safety in focus The simultaneously developed user management system provides the security required for tailored display configuration. The system’s integrated diagnostic function, including detailed alarm messages, increases operational reliability. For example, the OpenBridge screen display corresponds exactly to that of the control cabinet, which contains controller hardware. This enables any problems to be identified and located immediately, ensuring a fast and targeted response. OpenBridge is an open-source software; as such, it is unrestricted and free to use. According to Bachmann this was a conscious decision. The company wants people to use OpenBridge and work with it to develop new components and functions that support their operations. Importantly, OpenBridge only affects frontend design. And so, the user’s identity and expertise remain secure, Bachmann states. trouble-free operation for life!
