1. Start 2015: S355 is economic, sustainable and available.
I. Common pool of arguments, examples for economy and sustainability, design tools
II. Coordiantion with producers and stockholders about availability and additional
costs
III. Press informations, technical papers, webpages, newsletters by all IPOs,
producers, stockholders, fabricators etc.
2. Further Development.
Design tools, cost estimation, information for fabricators etc.
Repeat 1. and 2 with improved arguments and tool.
Ideas for next steps
