Schiffstechnik | Ship Technology © Payer Many young and also female delegates attended COMPIT 2019 of ship design by providing naval architects with a greater understanding of the design drivers at the concept phase. Using a structural simulation, such as a finite element model in conjunction with optimisation technology, including topology optimisation, yields a first time design simulation. He discussed the merits of the simulation driven design process and shows how it is applied to local structures on the UK’s Queen Elizabeth Class (QEC) Aircraft Carrier. Digital training & inspection Tracy Plowman and Volker Bertram from DNV GL, in their paper »A Hitchhiker’s Guide to the Galaxy of Maritime e-Learning«, present a valuable state of the art guide. The big advantage is the flexibility to train where and when you need it and to choose your subject individually. There is a misconception that digital means cheap. It requires cooperation between digital training experts and subject matter experts and takes longer than writing a book or an article. Generally it is not better nor worse than classroom training. The authors included sections on key technologies for digital learning, live online training, true e-learning, the role of simulations. The next decade will see digital training solutions on the rise. We will see classroom training – possibly improved by brain-friendly training techniques recently introduced – and blended learning and fully digital solutions together, as they address different training needs and have each their justification. Several participants have been to Compit before and some reported on progress with projects described at earlier events. One such well-known speaker was Erik Stensrud from DNV GL. He described progress in using drones to inspect big tanks in tankers and bulk-carriers. Success as well as limitations were reported and advantages such as cost savings and increased personnel safety are described. The final goal is to develop autonomous inspection drones to reduce the need to enter tanks. Survey duration and cost are expected to be significantly reduced, combined with major safety improvements for surveyors. Close-up inspection and non-destructive testing in enclosed and poorly lit environments are still challenges for the design of the drone. First results on navigational functions, computer vision, hyper spectral imaging and ultrasonic thickness measurements were highlighted. Paperless ship design? Not yet… Enrique Gaspar from NTNU, Alesund, discussed the past, present and future of computer-aided ship design. As a young university professor and service-provider without personal attachment to any established software, this smart fellow had an idealistic view regarding open systems and open data, and an optimistic view of the future: following an integrated approach to ship synthesis and assuming a more open attitude between the players we can make use of the vast existing data on ship design. With the developments underway in CAD, s. a. AI and Expert Systems, the ship designer should adjust his application to the relevant computer methods to provide an open, compatible and softer approach to CAD. Site & Tullamore Whiskey-Glas: Compit took place in Tullamore, which is mostly known for its Whiskey Ludmilla Seppälä from Cadmatic, Finland, explores the complexity of a simple question: Can vessels be built without the use of traditional drawings? This probably was the most philosophical paper of COMPIT 2019. She made her predictions with deep insight and explores the evolution of the role CAD played in the past and will play in the future of production and manufacturing in digital-driven shipbuilding. Looking into the future, a broad perspective is provided by foresight and socio-technological transitions and waves of transformation theories. Using the link between technological innovation and long cycles of economic growth and decline is common to most widely accepted frameworks within long wave researchers and futurists: great surges of development such as in the textile industry and the event of steam engines (1780-1830), steel and railways (1830- 1880), progress in electrical and chemical engineering (1880-1930), automobiles and petrochemicals (1930-1970), IT (1970-2010), renewable energies and © Payer 50 HANSA International Maritime Journal 06 | 2019

Schiffstechnik | Ship Technology Compit Award 2019 goes to Jialun Liu from Wuhan University of Technology. Presented by Volker Bertram sustainability (2010-20XX) induce socio-economic transformation effects across all economic activities and provide the critical driving forces for each long cycle economic growth. Do we experience a change in paradigm now, after the financial instability around 2010? Ludmilla argues: The leading role will belong to intelligent IT. CAD development in the past 40 years, for instance, tells us how a small innovation became the backbone of an industry. Besides being a modelling tool with interfaces to calculations and production systems it can become a cradle for all IT systems in shipbuilding and offshore projects: calculations, 3D modelling, production data, and further information management to serve as platform for Digital Twins and asset management in digital data-driven shipbuilding. Will we soon have paperless ship design? Ludmilla concluded, the maritime world is not there yet: Instead of a vision statement, the paper provides an analysis for the future of drawing-less production in shipbuilding. The main aim is to open a discussion and provide input for thought for those involved in maritime industry. n Compit Award for Jialun Liu Jiulun Liu has been announced as the winner of the »DNV GL COMPIT Award 2019«. The Chinese expert for unmanned ships received his PhD from TU Delft and is currently working as a lecturer in Wuhan University of Technology. Liu was honoured for his work on bringing unmanned shipping from concept to prototype maturity, in particular for the project of an unmanned ferry crossing the 2 km wide busy Yangtze river. The jury singled out Liu, from a short list of several highly qualified candidates, because his work combined various technologies contributing to the digital transformation of the maritime industries, namely Artificial Intelligence, robotics and Virtual Reality. In particular, his paper describes the Navigation Brain System (NBS) and its prototype application to a ferry across the Yangtze river. The Navigation Brain System is in loose analogy the senses and the brain of an intelligent (autonomous) ship, combining situation awareness and decision making for ship handling. It is also the first time that a ship operation topic was deemed most outstanding. The jury highlighted the clear structure and writing of the paper »Applying the Navigation Brain System to Inland Ferries«, as well as the attitude to make the future happen now with courage and technical skill, that seems to represent modern China. For the twelfth time, main sponsor DNV GL presented an outstanding scientist with the »DNV GL COMPIT«.
