SCHIFFSTECHNIK | SHIP TECHNOLOGY Innovation thrives in Covid times »Technologies for Future Ships and Future Shipping« was the theme of the 13th HIPER Conference, the second such event held in Corona times. Advanced thinkers from research and industry met in Tullamore, Ireland, to look into the crystal ball for our future Smart meets green: Robots inspect ships for fouling © Notilo Plus The larger themes will come as no surprise to the industry: the future will be green(er) and smart(er). But let’s have a closer look at some of the highlights and insights of this year’s HIPER edition. The overall impression was that the glass is half empty, half full. On decarbonizing shipping, we are gaining momentum on a broad front, as demonstrated by many diverse papers, ranging from early concept to first prototype experience. Still, there was a common feeling that we collectively have been off to a late start and, while doing better than some years ago, the decarbonizing train still needs to pick up more steam. Towards zero carbon On other environmental topics, notably moving towards more sustainable antifouling solutions, the common thread seems to be weaving the »greener« and »smarter« together, for greener, smarter solutions, reducing emissions to water and air through digital technology. And gone are the days where Artificial Intelligence was science fiction – it has arrived in mainstream applications from design to operation. And at least at HIPER, nobody raised an eyebrow about that. The future has already started, it seems. The course is clear – towards zero carbon. And we have assorted way points to reach in time. The most recent EEXI and CII targets of IMO dominate the discussion about the imminent future – 2023 is only 15 months ahead. As in football, the next match is always the hardest. Most ships should manage the EEXI and CII challenges, implementing engine power limitation and better hull management. But 2023 is just the begin of a process and we are well advised to not lose sight of medium and long-term goals. Ships built today shouldn’t perpetuate yesterday’s traditions – we need to start now on designs fit for 2030, with enough flexibility designed in to adapt thereafter on the road to 2050. This will require thinking out of the box, ingenuity, entrepreneurship, and boldly challenging my generation’s common wisdom. Change is in the air. LNG is but a bridging technology, likely to be largely history for shipping in 2050. »Fuel options for decarbonizing shipping« are multi-colored (green, blue, or even pink) and diverse, with no clear winner to be identified yet. Ammonia and methanol are currently seen by ahead of the competition by a whisker, but don’t write off hydrogen, algae-based biofuels or even nuclear energy yet. Predictions remain difficult and we will have to be resigned to continuous monitoring of markets and technologies. The only certain thing is uncertainty when it comes to shipping fuels of the future, except for two common features: we will need bigger tanks (or accept shorter range) and we will need bigger bucks, as most fuels under discussion now may be 2–3 times as expensive as standard pre-2020 fuels. And with new fuels come new energy converters. The 19th century saw the transition from steam engines (coal) to diesel engines (heavy fuel oil). With new low-carbon and no-carbon fuels, the 21st century will see similarly profound changes in the machinery: Dual-fuel diesel engines for main propulsion, fuel cells and batteries for electric power. Mining the 30 billion »The general trend may be summed up by more of everything: more installations and more power in the installations,« in the words of Benjamin Scholz, fuel cell expert at DNV. Many experts at HIPER looked at hybrid systems, combining more than one approach, e.g. diesel-electric systems. When using fuel cells, batteries or even solar panels, electric energy offers unrivalled flexibility in power distribution. Mårten Storbacka, Managing Director of WE Tech Solutions, described it as »key technology when building the future of ultra-efficient and zero-emission shipping«. While the medium and long-term focus is on alternative fuels, the short-term focus is on improving energy efficiency. Here the second-largest lever, after speed reduction, lies in improved hull management. The Clean Shipping Coalition estimated in an IMO 40 HANSA – International Maritime Journal 10 | 2021

SCHIFFSTECHNIK | SHIP TECHNOLOGY And the »HANSA Innovator Award goes« to ... This year‘s Maritime Innovator Award goes to Solène Guéré and Nicolas Gambini of Notilo Plus, a French start-up company specialized in underwater drones, underwater data collection and analysis thanks to artificial intelligence. Key components of Notilo’s innovations are Seasam and Notilo Cloud. The Seasam autonomous underwater drone investigated underwater hull condition and fouling. The drone is particularly easy to operate and stable as a platform. The Notilo Cloud solution creates automatic hull condition reports based on image material collected by Seasam drone or other sources. In combination, these innovations allow high-quality hull condition reports within the span of an hour. The jury singled out the solution for various reasons. It combines the two big trends in the maritime industries: digitalization and decarbonization, contributing to smarter and greener shipping. The application of Artificial Intelligence is smart and convincing, using the technology for drone robotics, optimum lighting in waters of varying turbidity, fouling type and coverage identification and report creation. The solution represents a significant contribution to better hull management, an area where we may still see two-digit improvements in energy efficiency, as needed e.g. for IMO’s CII thresholds soon to come. Award winner Solène Guéré and Nicolas Gambini of Notilo Plus together with HIPER organizer Volker Bertram Seasam and Notilo Cloud are now used by key shipowners, such as CMA CGM, and service providers around the globe, and are selected by DNV on its Veracity platform.
