SHIPLYS has been specified as necessary by our architect, shipbuilder and shipowner members, who, in order to survive in the world market, need to improve their capability to reduce the cycle time and costs of design and production, to be able to reliably produce better ship concepts through virtual prototyping and to meet the increasing requirements for LCCA (Life Cycle Cost Analysis), environmental assessments, risk assessments and end-of-life considerations as differentiators. Yet, the calculation and modeling to do this is difficult and time consuming, especially for SMEs without a large overhead of trained staff and tools, due to difficulties in integrating data between incompatible tools and formats for different design stages: conceptual hull design; the finite element calculations feeding preliminary and detailed designs; and virtual prototyping simulation models. This is coupled with the lack of an industry specific lifecycle modeling technique, hindered by the lack of information to support reliable decision-making. SHIPLYS aims to transfer experience from the development of industry modeling coherence schemes e.g. BIM (Building Information Modelling), and use them to produce new techniques for quick, reliable multi-disciplinary modeling capability for the marine industry: - Develop standardization aspects of the new paradigm by transferring the key BIM Product Model principles: identify and capture the useful implicit information in existing CAD/CAE data and develop data formats to provide persistence for data reuse between design stages - Develop a Virtual Prototyping system to incorporate LCCA, environmental and risk assessment criteria, for fast and cost effective evaluation of alternatives - Add multi-criterion decision analysis techniques to support decision making across the short/ long term, based on explicit formulation matrix of ‘Buyer Utility;’ the key purchasing decision criteria - To build on ISO10303 standards for interoperable data reuse

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.
