Cedi-index validation incircular fishing vessel design process

From the first economic crises (80’s) to the upcoming climate agreementswithCO2 reduction targets, the Dutch fishery (research) has been working to address sustainability in the fishing vessel design process. For designing complex fishing vessels, the sustainability aspects go beyond substantial Green House Gas emission reductions (GHG). It started with a sustainable crew in sound safety and health environments (SHE, 90’s),followed by integrating the People-, Planet and Profit sustainability aspects (Triple-P, Beamer 2000) and in 2015 the launching of a further sustainable pilot-fishing vessel (MDV-1, 30m). However, the shipping sector increasingly needs to adapt to societal-political changes complying with stricter CO2 emission reduction targets, anticipating the zero-carbon shipping by 2050 and emerging Circular Economy principles (CE).In a series of TU Delft PhD papers, the changing Dutch fishing vessel design processes have been described, from a multi-criteria design methodology via a sustainability-integrated design towards the development of Circular Economy Design Indexes (CEDI, part I, II and III)). With the CEDI design approach three crucial CE-factors are holistically combined (decarbonization, recycling, fish processing-automation), leading to a supportive pre-designtool. With which currently known and emerging green technologies can be applied and gradually ranked in a range of four technical sustainable MDV-1 redesign CE-concepts with, for the time being still too high ROI’s. Through further integration of the triple-P aspects the ultimate CE-, triple-Z targets are gradually achieved (zero-emission, zero-waste, zero-accidents). In this 4th paper the usefulness of the CEDI-indexes have been validated, redesigning the linear-sustainableMDV-1in a circular-sustainableMDV-1-Circularconcept. Instead of CE-intentions, a pathway is given to anticipate and integrate the new CE-principles in an early design stage with sustainable, technical feasible design solutions.
