'Divmalda' - the abbreviation of the project name - brings together sustainable technology and digitalization for the measurement of ship emissions. The solution to be developed will make it possible to digitally collect and officially verify ship emissions data in real time. This means it can be used as a reliable basis for reporting and monitoring processes and for emissions trading.

Ship operators and shipping companies are under pressure: reliable reporting of their ships'_CO2 and greenhouse gas emissions is now not only required by government agencies, ports, etc., but increasingly also by customers. They need information on the Scope 3 emissions of their supply chain for their reporting and to achieve their own climate targets. However, it is not yet fully possible to reliably record the emissions footprint of ships: ships usually have several tanks with different fuels, which can result in manual calculations and therefore possible errors in reporting. Automated reporting with verified data significantly reduces the manual effort and can thus minimize the error rate in order to support reliable statements on the greenhouse gas emissions of ships.

Goal: automated, digital solution

This is where Divmalda comes in: The aim of the three-year research project is to develop a system that uses innovative sensor technology to measure greenhouse gas emissions from ships in real time and make the data available in a cloud solution. This verified data is then transmitted to authorities, clients and other relevant bodies. Such a system saves ship operators and shipping companies a lot of work and gives them a competitive advantage, as reliable and transparent emissions data can be presented to charterers and cargo owners, for example. It also makes it possible to take advantage of existing reward systems for low-greenhouse gas ship operations. The verified data can also contribute to_{CO2-optimized} ship operation and be used as proof of reporting for emissions trading.

Consortium of strong project partners

Several partners have joined forces for this ambitious project under the leadership of Sick as a manufacturer of sensor technology and digital solutions for measuring emissions: CPO Containerschiff-Reederei and Flotte Hamburg, the operator of all official vessels in the port of Hamburg, such as police, fire department and pilot boats, are making their ships available for the project. In the course of the project, two container ships and a harbor ferry will be equipped with the innovative measurement technology developed by Sick as demonstrators. The Fraunhofer Institute for Software and Systems Engineering (Fraunhofer ISST) is responsible for data security and sovereignty. The Fraunhofer Center for Maritime Logistics and Services (Fraunhofer CML) and Det Norske Veritas (DNV), the international classification society, are responsible for verifying the data to ensure that it complies with international regulations on reducing greenhouse gas emissions. The Port of Hamburg (Hamburg Port Authority - HPA) receives the verified data and evaluates it.

The project participants are thus pooling their strengths and mapping the entire process chain from the data source to the recipient. All members of the consortium are investing in the project out of their own interest. The project is also being funded by the German Federal Ministry for Economic Affairs and Climate Protection, as Divmalda's objectives are in line with the German government's goals for the maritime industry - keyword 'Green & Smart'.

The International Data Space Association (IDSA) technology in the field of maritime emissions is being used for the first time for the project. With International Data Spaces (IDS), the IDSA offers a secure, independent and innovative data exchange system in which all participants can control their data completely independently in terms of data sovereignty and use it for business processes.
