Dear Reader,


“Hydro-structural” is the theme of this MARIN Report. On the face of it, hydro and structural are coupled to each other with a single hyphen. But behind this simple hyphen there is a world of problems and research challenges. It links two different worlds into one complex reality: the inter- action between the water and the structure. The resulting research challenges are exciting, as you cannot distinguish between excitation and response, between action and reaction anymore.


So you can see that there are good reasons for a MARIN Report focused on hydro-structural issues. You find them anywhere in the shipping and offshore world. In this Report there are many examples: mooring line integrity, container ship slamming and whipping, ship collision, wave impact loading on offshore structures and wind turbines, offshore structures in ice, LNG sloshing and the fatigue of FPSOs to name but a few. MARIN tries to link its hydrodynamic expertise to structural knowledge and has a special Hydro Structural Services (HSS) team. But it is clear we do not have all the necessary knowledge ourselves. This is why hydro-structural problems need cooperation and interaction with others. Where worlds meet, cooperation is essential. And, as in hydro-structural issues, the interaction is both ways.


When I was reviewing the articles in this MARIN Report and thinking about this editorial, I remem- bered a proposition I defended more than 10 years ago as part of the defence for my PhD thesis. To be awarded a PhD in The Netherlands, you are expected to have a slightly broader view on the world than just a technical one. The proposition was: “If you would analyse the relation between politics, the media and the public as a hydrodynamic problem, it would definitely be considered as a hydro- elastic problem”. I am afraid that the world of politics has shown that at least this proposition was true!
