Designing ISO containers is definitely fun. This was the first time I did something according to DNV, which proved to be a great experience. Also the project gave me a chance to show off some of my FEA skills, which felt great in the early days (and still do!)
Personally this was a very important project for me. It is the first design I have made with Sławek Labocha which in turn resulted in a long lasting friendship. We still work together, do trainings and we even wrote a book… it was fun to start, as I felt that finally I have met someone I could discuss problems with. Complicated design with nice people to work with… what more is there to expect from engineering job!
