D2.1 A report on selected scenarios and the rationale for such selection

Executive summary

Early on in the project and in the context of WP2, SHIPLYS participants have developed several different scenarios (case studies), each of them aiming at different challenges that European SME shipyards face today, which could potentially be dealt with by the software tool that will be developed within the project. This is with a view to understanding end users’ requirements and targeting the development of the SHIPLYS software activity towards such needs, thereby maximising the impact of the project to the intended audience.

Scenario 1 aims to optimise the design of a short-route ferry (domestic voyages) using a novel hybrid propulsion system, which combines internal combustion engines and battery cells. Carrying out an analysis for this scenario will cover the whole life cycle of the ferry, including design and production, operation and maintenance and scrapping and recycle stages. Scenario 1-A covers a shipyard already building new hybrid ships wanting to investigate the optimum mix of operation modes within the hybrid system.  Scenario 1-B aims to design and plan the retrofitting of a conventionally powered short route ferry with a hybrid propulsion system.  The retrofitting can be treated as new design requiring new building processes, but also including the disassembling process analysis of the existing conventional system. The hybrid system design and optimisation is the same as in Scenario 1-A.

Scenario 2 deals with the conceptual design of a new Multi-Purpose Vessel (MPV), which is assumed to be carried out within the environment of an SME shipyard, accounting for the shipyard’s constraints and using the SHIPLYS software tool to be developed.  The procedure involves an optimization of the design and production on the basis of a risk-based LCA, including features like risk-based structural design, production operation and maintenance optimisation, greener design for environmental impact, retrofitting options and end-of-life decommissioning.

Scenario 3 aims at supporting a repair shipyard during the bid stage to optimise retrofitting design and production and to arrive at realistic costs. The proposed retrofitting is the installation of scrubbers to cut funnel emissions or the installation of a ballast management plant. The improvement of retrofitting/repair of ships is of particular interest in SME shipyards. The scenario includes the calculation of Life Cycle Cost (LCC), performance of Life Cycle Assessment (LCA) and Risk Assessment (RA), which will quantify the overall cost and impact of the retrofit/repair works during the project implementation.

Scenario 4 focuses on production optimization in response to changing demand. Production optimization will lead to more competitive offers by the shipyards which are essential in the growth of their cycle of operations’ and profits. Production planning and simulation as well as the various solutions proposed in the scenarios like laser cutting, laser welding, laser-scanning quality controls, the use of new structural concepts like sandwich panels and the introduction of standardised assemblies, are to be investigated and included within the scope of the SHIPLYS software.
