Together with leading partners from the maritime industry, the HSVA is launching a large-scale project to develop an energy management system for ships that is based on rational methods. Participants are Hamburgische Schiffbau-Versuchsanstalt GmbH, AVL Deutschland GmbH, Entwicklungszentrum für Schiffstechnik und Transportsysteme e.V., Friendship Systems AG, Technische Universität Berlin, Technische Universität Hamburg, 52°North – Initiative for Geospatial Open Source Software GmbH, Universität zu Lübeck, Maritimes Zentrum der Hochschule Flensburg, Carl Büttner Shipmanagement and AVL Software & Functions. Together with other associated shipping companies, a future-oriented energy management and decision support system is to be developed, taking into account current operational status data as well as geoinformation. This will contribute to improving energy efficiency and reducing emissions from shipping.
