6 First in Freefall Report interviews the only aluminium Freefall lifeboat builder in the world,


Verhoef Aluminium. 9 Dropsim gives new understanding of the operational


limits of freefall lifeboats With the successful validation of the software tool Dropsim a huge step forward has been made in determining the operational boundaries of freefall lifeboats.


12 The Human Factor The human factor has always been an important area of research, and here we


outline the many ways MARIN is involved.


14 Assessing the human factor in offloading operations Quantifying risks during offloading operations by the assessment of human factors


is the subject of a fascinating study.


15 Speed@Sea The goal of the Speed@Sea project was to assess the limiting aspects and


criteria for fast sailing vessels.


16 Project provides insight into passenger ship comfort MARIN starts two-year research programme with the passenger sector to enhance


industry knowledge and to improve comfort levels.


18 Collision risk assessed with AIS data AIS data is now being used to determine the collision risk for offshore installations.


19 IMO Minimum Power Requirement – A way ahead


in adverse conditions New JIP aims to deliver better design for sustained speed in a seaway following new EEDI regulations.


20 ReFRESCO-operation gives unique opportunities in CFD A new maritime CFD development, validation and application was launched.


21 Future-proof hull fairing tool developed By combining GMS with the strengths of Rhinoceros, MARIN now has a


hull shape drawing tool ready for the future. 22 Free concept testing well received by


Dutch maritime innovators MARIN decided to create a Concept Basin in 2013 and less than a year on, several new initiatives tested there have already been successfully launched.


That is why we want to share our specialised maritime CFD code ReFRESCO and our computer cluster with you (see page 20). Let’s explore the new possibilities of CFD together! Our expertise about fluid flows and our experience in the interpretation of results are at your service. They are our added value.


Dear Reader,


When I was a teenager, I worked in a photographer’s shop on Saturdays. This allowed me to finance my photography hobby. My dream was to have a Hasselblad camera like my boss: large size negatives, top quality lenses and very robust. Only professional photographers could afford such cameras and it gave them a sort of ‘monopoly’: for really good pictures of the family or special occasions you had to involve the professional.


Times have changed. Negatives are replaced by digital sensors and focusing or light balancing is completely automatic. Expensive cameras have been replaced by smart phones with millions of pixels. But there are still professional photographers. Their knowledge of light and creativity is their added value.


I always have to think about this parallel if we dis- cuss the future of Computational Fluid Dynamics (CFD). In the old days, hydrodynamic investigations were purely the field of specialists. Only research organisations such as MARIN could afford expensive testing facilities and they too, enjoyed a type of monopoly. Model basins are the Hasselblads of this age. And even the first hydrodynamic calculation methods required such a computational power that only large organisations could afford them.


Nowadays, however, time domain simulations are available to everybody. CFD calculations can run on office computers and give important insights into the fluid flow. But there are still professional hydro- dynamicists like us at MARIN. We believe that the key to this new age is interaction.
