Presentation of the activities within the work package on ‘Digital twin ship design for real-life conditions in waves’ by Henrik Mikkelsen, Aerotak

In the last decade, ships have increasingly been optimized for a range of draughts and speeds in calm water to reflect the operational profile. However, it is fair to say that the state-of-the-art ship design philosophy in both the Danish and international contexts are mainly based on calm water conditions, while a margin of performance expectations is often added to empirically consider the added resistance due to wave effects.
Consequently, ship hulls and propellers are not necessarily optimized for the actual operational profile and wave conditions that ships will operate in.Within the project period the aim is to establish and demonstrate tools and procedures that can be used to support the design of the next generation of vessels, which to a higher degree are optimized for real-life conditions in waves, compared to current methodology focusing solely on calm water.
The goal is to be able to optimize vessels that are more fuel-efficient than what can be achieved with the current methods to support the shipping industry in the process of meeting the future emission targets.
ShippingLab is initating a new large project focusing on developing technologies on advanced ship design, biofouling, remote navigation, predictive maintenance and the well-being of seafarers.
The leading partners in the project will present their activities, and ShippingLab will talk about the different possibilities to be part of the many activities performed to develop and support Blue Denmark.
It is the Government’s stated ambition to maintain and expand Blue Denmark's position as a growth engine in the Danish economy. ShippingLab implements this ambition, having stakeholders across the maritime industry joining efforts on pre-competitive initiatives.
In a new, large ShippingLab collaboration project starting on May 1, 2024, the partners work together on increasing energy efficiency, accelerating the green transition of the global maritime sector, and developing the position of Blue Denmark as frontrunner for decarbonization and energy-efficiency.
The project sets three key goals that will increase job and value creation compared to 2020
• Reduce CO2 emissions of the Danish fleet by 25% by 2030
• Increase the turnover by 30% by 2030
• Attract 40% more students to maritime MSc programmes
With the launch of SLGREEN at the ShippingLab platform, the Danish maritime community initiates ambitious maritime research, development, and innovation. Building on valuable experiences starting in 2015 with Blue INNOship and the ShippingLab platform initiated in 2019. The wide range of partners – from established, large corporations to new, emerging businesses, universities and maritime university colleges, GTS institutes, organizations, and public authorities etc. – ensures a valuable maritime collaboration on research, development, testing and validation of innovative solutions that supports the common goal of SLGREEN. Further, the presence of some of the largest ship owners within the different segments underlines and value derived from the activities from SLGREEN.
The technological objectives of SLGREEN meets the overarching objective and responds to the global challenge by developing up to TRL7 an array of digital technologies that contribute to the goals:
• Objective 1: Develop vessel performance prediction tools to improve navigation in waves
• Success Criterion: A digital twin for vessel performance in waves tested on commercial routes
• Objective 2: Develop biofouling prediction models for managing hull performance
• Success Criterion: A biofouling prediction model is integrated into the vessel performance system of partner ship owners
• Objective 3: Condition monitoring and wear prediction model for marine combustion engines
• Success Criterion: A digital twin for predicting wear is integrated into the engine performance monitoring system of partner engine-maker
• Objective 4: Develop an integrated system for digital pilotage enabling remote navigation
• Success Criterion: The digital pilotage system is validated through full-scale demonstrators
• Objective 5: Develop a system for improving the comfort and health of crew on board
• Success Criterion: A digital pilot demonstration and guidelines on mitigation technologies
