TECH-INNOVATION POWERED BY VDMA - MARINE EQUIPMENT AND SYSTEMS LIEBHERR Largest slewing drive Inspired by Jacques-Yves Cousteau, Liebherr customer eConowind develops an innovative sailing system. Up to 40 m in height, futuristic metal sails serve as propulsion support for cargo ships. The world’s largest slewing drive units turn these huge sails. Using wind power in this way, fuel costs can be reduced by up to 20 %. When used on the high seas, the Liebherr products fully demonstrate their advantages, the company says. The slewing drive units are self-contained systems consisting of a drive and a bearing unit. This makes the components particularly resistant to extreme environmental influences, such as salt water or dust. Special sealing systems and surface coatings also add to the high resistance of the large components and make them ideal for use at sea. The massive, worm-driven components from Liebherr measure 1,720mm in diameter each and weigh together over 1.4 t. A worm shaft weighing over 40 kg, which already enables a notable 218,500 Nm of torque at module 8, drives the components. For more power, the slewing drive can be configured up to module 14. It is also possible to design slewing drives with two drive trains. In the construction and design of the slewing drives, Liebherr draws on »its many years of experience as a manufacturer of drives and slewing bearings, venturing at the same time into new dimensions«. For the manufacturing process, for example, the company uses its own special tools, such as the diamond milling head. It was specifically developed for the worm gearing. © Liebherr GEA GROUP Net-zero GHG emissions by 2040 GEA Group today announced a comprehensive climate strategy. With the corresponding climate targets, GEA is making a clear commitment to achieve net-zero greenhouse gas (GHG) emissions along its entire value chain by 2040. The company has submitted its netzero commitment and 2030 interim targets to the Science Based Targets initiative (SBTi), the globally recognized, independent body for reviewing climate targets. Validation of GEA’s interim targets by SBTi is expected in the second half of 2021, confirming GEA’s targets are aligned with the latest climate science and are effectively contributing to the 1.5 degrees Celsius target of the Paris Agreement. »We are pursuing the most comprehensive and ambitious climate strategy in the mechanical engineering industry,« says Stefan Klebert, CEO GEA Group. By investing globally in Gold Standardcertified projects to generate clean energy from wind, sun, biomass and waste gases, GEA‘s own operations are already climate-neutral since the beginning of 2021, the company states. In addition to the 2040 net-zero target, the company has submitted interim sciencebased targets across all relevant scopes. Compared to the baseline year 2019, GEA aims to reduce both GHG emissions from its own operations (Scopes 1 and 2) by 60% and GHG emissions from the customer use phase of its products (Scope 3) by 18% by 2030. The climate strategy is described as the first building block of a comprehensive Environment, Social and Governance (ESG) strategy. Beyond climate protection, this strategy is supposed to also take social and corporate governance aspects into account. It shall reinforce the company’s commitment to United Nations Sustainable Development Goals and become a foundational element of »Mission 26«, GEA’s new corporate strategy that is currently under development. »Mission 26« will be presented at GEA’s next Capital Markets Day in September 2021.

TECH-INNOVATION POWERED BY VDMA - MARINE EQUIPMENT AND SYSTEMS VDMA WORKING GROUP »MTP IN SHIPBUILDING« »Module Type Package« – long-awaited digital standard developed VDMA is presenting the new MTP standard after four years of development, opening the way to link together machine and system components seamlessly and quickly, avoiding time-consuming discussions over interfaces in the ship automation system. MTP (Module Type Package) describes the standardization of communication between systems and control level: This reduces complexity for all participants along the shipbuilding value chain. If the mechanical modularisation can also be transferred to the automation system, users in the shipbuilding supply chain can achieve speed advantages in engineering and quality improvements in the integration of subsystems. The MTP is a description format with which automation can be realized as a »service-oriented software architecture«. Due to both cost pressures and environmental requirements, modern ships must rely on increasingly complex technologies. But on-board digitalization itself won‘t make everything better automatically – a standard is needed to link different systems with rapidly increasing number of signals efficiently and securely. In the MTP working group, the leading manufacturers of ship automation technology work together with mechanical engineers, system integrators and experts from shipyards and universities. With this approach, maximum acceptance of the developed standards is achieved, as the concrete advantages for all stages of the value chain are part of the project right from the start. Within the framework of a VDMA standard sheet, the standard currently being developed for process engineering is adapted to the shipbuilding industry. This means that the tried and tested from a technically related sector can be used, which makes implementation in the shipping and shipbuilding industry even easier.
