6 The challenges of building the biggest cruise ship in the world Report interviews Loic Morand, Head of STX Europe’s Hydrodynamic Department, about the wide-reaching test campaign performed at MARIN for the world’s largest cruise ship – the magnificent ‘Symphony of the Seas’.

9 Real-time simulations to test propulsion alternatives Assisting owners in making important decisions about which propulsion or thrusters

are best suited to their yacht by using virtual reality.

10 Advanced backbone deployed to measure bending modes of ultra-large container vessels A series of model tests carried out on behalf of MARIC assess the flexural response of ULCV.

12 Prediction methods for sailing yachts in the early design phase A roundup of studies and tools that can be used in the early design stages.

14 Addressing the elusive issue of comfort onboard The assessment of comfort onboard a yacht is not an easy task. Working group led by

MARIN aims to develop a comfort standard and a new JIP will develop tools, and obtain and analyse data related to comfort levels.

16 Deformation measurements of a flexible, composite propeller carried out on a sailing vessel The design of a flexible propeller requires the development and validation of methods able to predict its complex hydro-elastic behaviour.

18 Tackling increasing cruise vessel dimensions in virtual reality Simulator research and advanced simulator training for Meyer Werft.

20 Floating Future Seminar and BlueWeek success Seminars and workshops spark innovation and contribute towards a more sustainable

use of our oceans.

22 ReFRESCO successfully coupled to ParaView Catalyst for in-situ analysis New ReFRESCO/ParaView Catalyst combination has several major advantages - saving time and storage.

23 New McdSeries tool: design CP propellers using the WAGENINGEN CD Series Within the scope of the CD Propeller JIP, a modern series of controllable pitch propellers was developed. The ‘McdSeries’ software tool allows you to design CPP on the basis of these results

Dear Reader,

It was difficult to miss: the exciting culmination of the Volvo Ocean Race. After a relentless battle against the elements, the race was decided along the shores of The Netherlands by good tactics and seamanship. Thousands of people watched the race from the beach, trying to spot the ships on the horizon.

For me this was the most important achievement of the race: it turned our attention towards the sea! As citizens of this Blue Planet we don’t realise that 90% of our goods are transported over water. And we often don’t know about its potential for the sustainable production of food and energy.

Therefore it was a great idea to hold ‘Ocean Summits’ at all the stopovers during the race. At most places the focus was on the problem of plastic pollution, but in The Hague we broadened the theme under the slogan ‘The future of the ocean lays in our hands!’ We looked beyond the horizon for a better future for the oceans: fighting plastic pollution, but also promoting zero emission shipping, developing ocean energy, performing ocean research and working on sustainable growth.

It will not surprise you that MARIN’s main focus was on zero emission shipping. The Volvo Ocean Race inspires us to look at wind-assisted ships, and electric and even hydrogen-powered vessels!

We also emphasised that people as consumers also have a voice, and can stimulate zero emission shipping. Just as we can stop using plastic bags, we can also decide to pay a bit more for our goods so we transport them sustainably. MARIN calculated the costs involved: for only € 0.50 extra per pair of sneakers we can get completely rid of Heavy Fuel Oil and consequently, its large levels of sulphur. That is less than 1% of the costs! And if we really go to zero emissions, deploying hydrogen-powered ships, it is only € 3.50 extra (less than 5%).

Let’s go for ‘Blue Shipping’ with zero emissions. It is not so far beyond the horizon!
