What is the current position on the digital journey of the maritime industries? The 18th Conference on Computer and IT Applications in the Maritime Industries (COMPIT) will give an insight. An exclusive preview by organizer Volker Bertram of Tutech Innovation Over the past two decades, COMPIT has established itself as a key conference in information technology (IT) for the maritime industries, bringing together software developers and users, designers and operators. The three-day conference is structured into 12 sessions. The main trends are: Digital Twin splits and mutates: The Digital Twin grows and evolves as the real ship does. But he mutates along the way and often he dies (at the shipyard) and resurrects (at the ship owner). In essence, we adopt multi-facetted and multi-fidelity simulations to aid our decisions from the first concept to fleet in service. As long as we don’t know (or define strictly) what is a Digital Twin and what is not, not only marketing people (ab)use the term happily for anything that involves an engineering model or simulations. As a special application, designers like to review and communicate now in Virtual Reality, at least for the look, if not the feel. Digital Training on the rise: Everybody hates e-Learning, everybody does e-Learning. But teething problems in digital training solutions are addressed and for a global and fragmented industry like ours, the reasonable advice seems to be: Resistance is futile – embrace digital (training). Ship Operation 4.0: Long gone are the days where ship operators thought that having a PC for accounting and stock management meant they were computer-savvy and digital. Enter the world of Big Data and Artificial Intelligence (machine learning). Oh well, marketing storms it with flying color and grandiose claims. Mind the gap to current reality, but the few real applications shown merit attention. This does not just concern the »autonomous ship«, but also assorted applications for smarter operations, in energy saving and asset management. The elusive Digital Twin The Digital Twin is a much used (and abused) buzzword in the industry. The original vision was a 3d product data model, which mimics the behavior of the ship in a multitude of simulations and updates this behavior over the lifetime of the ship. The dream was to have a computer model with the look and feel of the real deal. Dreams die first. As with Virtual Reality, the vision was much grander than the reality of current implementations. The life-cycle has been conveniently chopped up and we now hear »Design Digital Twin« or »Digital Twin for Operation«. And we have high-fidelity twins, and low-fidelity twins. (Maybe we are all low-fidelity twins of George Clooney?) The distinction between a simulation model and a specialized Digital Twin is no longer clear to me, but what’s in a name if the appli- 66 HANSA International Maritime Journal – 156.

Tapio Hulkkonen (Napa) presents a textbook example in »Using Operational Fleet Intelligence Data together with 3D Product Model in Structure Analyses during Ship Life Cycle«. Here we have the original dream (3d model, finite-element simulations, and life-cycle tracking and updating from operational sensor data), even if »only« applied to the remaining fatigue life of ship structures. Royston Jones (Altair) combines two hot topics in his »The Development of the Intelligent Digital Twin for Autonomous Navigation Vessels«. Digital Twin meets Autonomous Ship. You have our attention, Mr. Jones! Digital Twins in design may use the power of Virtual Reality. Chris Cassar et al. (UCL, BMT) show »The Implementation of Virtual Reality Software for Multidisciplinary Ship Design Revision« and Hans van der Tas (DEKC Maritime) reports positive experience on »Communicating Ship Designs via Virtual Reality«. A common theme is that VR can be a powerful communication tool, especially if 3d views (with zoom, turning and moving) are combined with product data model information and possibly simulations. Robert Spencer (Stirling Labs) sums it up: »The future of ship design will undoubtedly include Virtual Reality in some form, [but] deploying Virtual reality technology often requires rethinking workflows.« Digital Twins play a leading role also in state-of-the-art energy efficient operation. In operation, hull performance monitoring is a prime example of using Digital Twin concepts. Myeong-Jo Son et al. (Korean Register) present a »Big Data Analysis Application: Brake Power and Fuel Oil Consumption Estimation based on Public History Voyage Data of Shipsq, merging AIS data and met-ocean data with simple hydrodynamic estimates based on public ship design data. Looking at 4,000 ships, they can identify typical and best-practice operational patterns as benchmarks for individual ship performance monitoring. But what happens when we bring the latest and greatest web technologies to the more traditional naval world? This provocative question is raised by COMPIT 2019 25–27 March | Venue: Tullamore/Ireland | www.compit.info Day 1: »Zen & the Art of Computer-Aided Ship Design«, »Optimizers do it better«, »All Simulations Great and Small«, and »VR-tigo«, Day 2: »Come Together [, technologies]«, »Digital Twin«, »Tutti Frutti«, and »Digital Training« Day 3: »Smooth Operator«, »Seeing Eye-to-Eye with A.I.«, »Autonomy Now«, and »Unmanned Ships on the Horizon« Registration by email to volker.Bertram@dnvgl.com A company of Clean energy in port The Becker LNG PowerPac® supplies clean power to ships in port such as container vessels, car carriers and ferries. Compared to using on-board diesel engines to produce power, the system’s power supply dramatically reduces harmful emissions. Another product, the floating LNG Power Barge, is an environmentally friendly cold ironing solution for cruise ships in port. www.hybrid-port-energy.com HANSA International Maritime Journal – 156.
