Grønn Skipsfart: Et Maritimt Kinderegg Grønn teknologiutvikling – ønskedrømmer og realiteter Innledning til debatt ULSTEIN INTERNATIONAL DR. PER OLAF BRETT V1.0 MAY 2015 CHALLENGING THE DESIGN FOR X – PERSPECTIVES… “One”-dimensional ship design approaches can, typically, be described by the Design for Xconcepts - X being, for example: – The Design for Safety – Design for Sustainability – Design for Environmental Friendliness – Design for Reliability – Design for Energy Efficiency – Design for Life Cycle or Design for Production – … All vessels have a purpose! WWW.ULSTEIN.COM TURNING VISIONS INTO REALITY TYPES OF MEASURES OF MERIT The choice of a solution from many alternatives must be made on the basis of one or more criteria. Traditionally, in the marine industry, the criteria are generally based on economic considerations and called measures of merit Criteria based on cost (1960-1970) H. Benford – Cost of investments (CAPEX) – Cost of operation (OPEX) – Cost of voyaging (VOYEX) Criteria based on cost and income (1970-1990) I. Buxton, S. Erichsen – Net present value – Annual rate of return – The payback period – Internal rate of return – Project cash stream/value – Vessel cash stream/value Critria based on expectations (1990- …) M. Stopford, Weijnolst & Wergeland, A. Papanikolao, D. Andrews, P.O. Brett et.al WWW.ULSTEIN.COM Choice of perspective is important… TURNING VISIONS INTO REALITY WHAT IS A BETTER VESSEL FROM WHAT PERSPECTIVE? EFFICIENCY WWW.ULSTEIN.COM EFFECTIVENESS EFFICACY TURNING VISIONS INTO REALITY INDEX-BASED RANKING OF SHIP DESIGN SOLUTIONS Results from index-based rankings of 13 different real vessel designs based on the Ulstein UGPI-concept WWW.ULSTEIN.COM TURNING VISIONS INTO REALITY CASE STUDY – WHAT SOLUTION MEETS BEST THE PRE-SET EXPECTATIONS OF THE STAKEHOLDERS AHP-model of the Smarter, Safer, and Greener effectiveness perspective Importance ratios: – Expert judgment & statistical analysis – Smarter: 60% – Safer: 23% – Greener: 17% Target point is equal to importance ratios – Solution 4 is a Smarter solution – Solution 2 is a Greener solution – Solution 6 is a Safer solution Solution 4 achieves higher overall score applying the importance ratios WWW.ULSTEIN.COM Target point TURNING VISIONS INTO REALITY Technical and operational challenges? The ships: Improved turnaround time More space and capacity for payload Better sea keeping and manoeuvring capabilities Multipurpose capacity Minimal repair and maintenance needs The designs: More simplistic and cost-effective ship designs ”Smarter” ships “Smarter” shipbuilding “Smarter” functionality The operation: Integrated transport services (door to door) Professionalized commercial operations More efficient ports and hinterland connections Port facilities: Ports with shorter entrance New port developments and upgrades of old ones New and alternative solutions for cargo handling and further hinterland distribution Are we willing to change the approach?
