Schiffstechnik | Ship Technology The Japanese vision of ships 30 years from now: Biomimetic ship hulls may develop as ultra-light carbon materials are used, 3D printed with embedded smart sensors Smartphones and drones as team-players »Technologies for Future Ships and Future Shipping« is the theme of the 11th HIPER Conference. Advanced thinkers from research laboratories, authorities and industry meet in Zevenwacht, South Africa, to look into the crystal ball. By Volker Bertram Looking at the program of the conference, where HANSA is offcial media partner, two key messages stand out: Don’t forget your smartphone – Smartphones may be used for phone calls. But we can use them for so much more: Ship stability tests, e-learning, guiding workers in shipyard assembly, or booking virtual towing tank tests in the cloud. Digital solutions are changing the way we do business in our industry as we speak. New entries in the market are challenging the established traditional players. There are threats and opportunities – we need to be aware of both. Drones become team-players – Of course, no discussion of future technologies can avoid unmanned or autonomous ships. The good news: drones are team-players. On land, we see shipyards 4.0 emerge, where smart machines (cranes, cutting machines, welding robots, etc.) communicate automatically using internet technology (IoT = Internet of Things). Ship technology will advance beyond current transponders, AIS and performance monitoring. We are moving towards a scenario where the movement of traffc conventionally manned ships, highly autonomous but still manned ships, and, at least partly, teleoperated manned ships, will be tracked and traffic coordinated. The Norwegian Maritime Directorate has already formulated a roadmap for this eventuality. Ring, ring Future naval architects may no longer know what a drawing board is, but they will certainly need their smartphones. Modern smartphones contain sensors, a processor unit, and a versatile human machine interface display, which can be used for so much more than just calling or texting. Not only will we all be more connected within our business, but smartphones will take our ways of doing business to the next game level. In some cases, literally so. Tracy Plowman of DNV GL’s Academy discusses »Maritime e-Training – Matching Requirements to Solutions«. E-learning comes in many forms and price levels. The SurveySimulator uses virtual reality gaming technologies to familiarize trainees with ship structures, regulations and survey techniques. Smartphones can be used to refresh memories (albeit at lower resolution) or to tune in to webinars on the latest developments. Mohamed Djebli (Oran University of Science and Technology) uses a smartphone as measurement instrument in a ship stability inclining test. The results agree well with conventional tests. Considering its convenience and cost savings, this new method may find quickly adoption, particularly for fishing and recreational boats. Naval architects (and other stakeholders like ship operators) could also use smartphones to book (virtual) towing tank tests online, as presented by Karsten Hochkirch of DNV GL in »Cloud-Based Numerical Towing Tanks: Anytime, Anywhere and for Anybody«. More precisely, we should speak of virtual sea trials, as the simulations overcome the scale-effect problems of traditional model basins and allow a direct look at the flow conditions of the full-scale ship. The customer only needs to upload the geometry, the desired set of draft and speed conditions, and the credit card info. Response times and costs are significantly lower than in physical model testing. How do they do Source: National Maritime Research Institute Japan 44 HANSA International Maritime Journal – 154.

Schiffstechnik | Ship Technology it? The answer is given to large extent by Thomas Hildebrandt (Numeca) and his co-authors in »The Democratization of High-Performance Marine CFD«: The cloud offers virtually unlimited computing power to rent by the core (or processor) hour. Software vendors like Numeca also now offer the required licenses by the hour. If you add CFD experience, recurrent similar shapes, and automate images, curves and report layout, you only need to add the business transaction and the whole process has been digitalized. For more exotic, out-of-the-box designs; Like the foil-supported trimaran that can turn into a submarine – will it feature in the next James Bond movie? – presented by Prasanta Sahoo of the Florida Institute of Technology, we still need tailored investigations by human experts, but for the rest the virtual trials online are a good example of what digitalization means. Smartphones and tablets will also become standard equipment for workers on shipyards if we follow the vision of Kohei Matsuo of the National Maritime Research Institute in Japan. Faced with high wages and recruiting problems for shipyard workers, Japan sees reducing the man-hours needed to assemble ships as the way forward. Using Augmented Reality (overlaying instructions to the screen view of the smartphone or tablet), the worker gets very intuitive and clear instructions on how to assemble parts, while the as-built status is updated in real time, making work progress much more transparent. Get smart(er) Machines and ships get smarter, but autonomy comes gradually. The multitude of sensors embedded in ship equipment results in a mass of data which can aid design and operation. Stein Ove Erikstad (NTNU) discusses Big Data as a new resource for ship designers in »Merging Physics, Big Data Analytics and Simulation for the Next Generation Digital Twins«. Annie Bekker (Stellenbosch University) described how the wealth of on-board data is used in the new South African polar research vessel ‘SA Agulhas II’. John Fernandes (Nelson Mandela Memorial University) describes how the smart systems on board ships of the future will work together in a structured framework in »Totally Integrated Automation for Ships: A Step Closer to Industry 4.0 Realization«. Svein Medhaug presents the Norwegian Maritime Directorate’s take on the future of autonomous and remotely controlled ships and national and international regulations. The focus lies here on smaller units such as workboats and feeder vessels. While the unmanned 20,000 TEU containership remains science fiction, drone technology is increasingly finding maritime applications. Chris Lewis of the French XPRIZE contender Eauligo, describes how swarms of low-cost drones mimic bees in self-organizing for underwater mapping and search tasks. The deep blue is one of mankind’s final frontiers and cooperative robots will play a key task in unlocking its secrets. Lectures from notable experts Several keynote lectures highlight different aspects of future ships and how we will design and operate them. Herbert Koelman (SARC) describes trends in computer aided ship design. While DNV GL and Hempel have joined forces to present various contenders for a biocide-free future in marine antifouling. Ultrasonic protection, as discussed by Jan Kelling of Hasytec, is being tested by the South African navy, not least because of its ability to continue to provide protection when the ship is idle for longer time periods. Kohei Matsuo (NMRI) gives an overview of »Innovative Technologies for Maritime Industry & Future Scenario«, setting out the technologies that are most likely to affect the maritime field and the scenarios which result. Julien Sellier (STRUCTeam) covers the use of composite materials for ships. The hull is likely to remain cheap and easily recycled steel, but a multitude of equipment and outfitting parts will become “plastic”, not least because of 3d printing of spare parts on demand. So, while so many stories about the maritime industry focus on the negatives, the positives are out there if you look for them. Forget the prophecies of doom! The industry is reinventing itself and its innovative drive is impressive.
