Since the late 1980s, there has been renewed interest in contra-rotating propellers (CRP). Their use is particularly beneficial under high thrust load conditions. It is estimated that energy savings of up to 10% can be achieved. Therefore, a CRP used as the main propulsion system can represent an effective means of reducing CO2 emissions.

ShipNET – AI Ship Modelling Approach for Multidimensional Design
2024 – 2028
With the ambitious goal of decarbonising the shipping industry and reducing greenhouse gas emissions by at least 50% by 2050 compared to 2008 levels, the International Maritime Organization (IMO) has introduced regulatory measures such as the Energy Efficiency Existing Ship Index (EEXI), the Energy Efficiency Design Index (EEDI), and the Carbon Intensity Indicator (CII). These measures enforce stricter standards for ship design and operation, compelling shipowners and designers to adopt innovative solutions that improve energy efficiency and environmental performance.

AkuZy – Hydroacoustics of Cycloidal Propellers
2025 – 2028
Since 2008, the International Maritime Organization (IMO) has assigned high priority to the issue of underwater acoustics. The objective is to reduce anthropogenic noise pollution in the oceans in order to safeguard the health of marine ecosystems.

ESDP@ODC – Energy Saving Devices and Propeller at Off Design Conditions
2025 – 2028
The global shipping industry is confronted with the imperative to achieve maximum possible decarbonization. This objective must encompass not only the operational phase of vessels but also the resource-intensive shipbuilding phase. To mitigate greenhouse gas emissions during vessel operation, the implementation of Energy Saving Devices (ESDs) is becoming increasingly prevalent — including technologies such as wake equalizing ducts and, more recently, bow fins.

AKUOPT – Acoustic prognoses for route and operating profile optimization
2025 – 2027
Globalization has led to an exponential increase in traffic density on the sea routes due to the strong growth in world trade. At the same time, a significant increase in noise levels in the oceans has been observed in recent years. For this reason, underwater acoustics have been a high priority for the International Maritime Organization (IMO) since 2008. The aim is to reduce the anthropogenic acoustic pollution of the oceans in order to ensure the health of marine ecosystems.

WIND – Development of test methods for wind-assisted seagoing vessels
2024 – 2026
Due to the increasing integration of wind actuators on seagoing vessels, there is currently an increased need for prognosis methods in order to adequately take into account the consequential effects caused by the use of wind actuators. Consequential effects such as increased drift angles and significant thrust loads on the propeller can lead to significant changes in the propulsion coefficients. For a targeted design of the propulsion system, the effects of a secondary wind propulsor on the overall system must be recorded as accurately as possible and taken into account in the scaling methods.
