RETROFIT SOLUTIONS TO ACHIEVE 55% GHG REDUCTION BY 2030

该提案开发了一系列节能解决方案，可以在改造中采用，以实现35%的温室气体排放。两项新技术，即风力辅助船舶推进和创新的空气润滑系统，将与其他解决方案一起开发，尽管这些解决方案基于已经成熟的技术，如操作和流体动力设计优化以及船舶电气化，但必须进行扩展，以与新的解决方案相结合，以及处理原始船舶设计带来的限制。RETROFIT55的最终目标是创建一个先进的基于网络的决策支持系统(DSS)，它将不同系统的数字孪生兄弟融合到一个集成的数字船舶模型中。DSS将采用一系列最新的改装解决方案，这些解决方案在项目结束时可以随时部署，在TRL 7-8上开发和演示时很容易扩展，适用于不同的船型和运营环境。决策支持系统将使用户能够通过组合适用于特定船型的不同选项，并在生命周期成本、投资回报和几个关键绩效指标(如EEXI、CII)方面进行比较，来配置改装。关于ZEWT战略，除了主要为设计和改造做出贡献外，该项目的实施还将涉及其他主题，如使用可持续替代燃料、能源效率、电气化和数字绿色。该联盟的成员包括大学和研究机构、三名新技术开发商、一家船舶设计室、软件开发商、ICT专家、一家船级社、一家船舶维修公司和两家大型船舶运营商。

The proposal develops a combination of energy-saving solutions that can be adopted in retrofitting aimed at achieving the 35% of GHG emissions. Two new technologies, i.e. wind assisted ship propulsion and an innovative air lubrication system, will be developed together with other solutions that, although based on already mature technologies, such as operational and hydrodynamic design optimization and ship electrification, have to be expanded to be integrated with the new solutions as well as to cope with the constraints posed by the original ship design. The final objective of RETROFIT55 is to create an advanced web-based Decision Support System (DSS), that fuses together digital twins of the different systems into an integrated digital ship model. The DSS will feature a catalogue of retrofitting solutions that are up-to-date and ready to be deployed at the end of the project and easily extendable afterward while developed and demonstrated at TRL 7-8, suitable for different ship types and operational contexts. The DSS will enable the user to configure the retrofitting by combining different options which are suitable for the specific ship type and comparing them in terms of life-cycle cost, return-of-investment and several KPIs, such as EEXI, CII. Referring to the ZEWT strategy, while primarily contributing to the Design and Retrofit, the implementation of the project will also intersect other topics, such as Use of Sustainable Alternative fuels, Energy Efficiency, Electrification and Digital Green. The consortium brings together universities and research institutions, three developers of the new technologies, a ship design office, software developers, ICT experts, a classification society, a ship-repair company, and two large ship operators.
