Schiffstechnik | Ship Technology en, multi-objective design of both the hull and the propeller in CAESES and MAXSURF and came up with a solar powered self-righting ASV design. The hull already has been built, solar modules and engine are under construction. As autonomous operation becomes also interesting for commercial vessel operation in crowded sea traffc areas, collision avoidance of unmanned craft was one of the major topics of the conference. Several groups of researchers looked into »Virtual reality will be more successful in shipbuilding than in the consumer space« Denis Morais, SSI the possibilities of COLREG-compliant ASVs. Richard Daltry of ASV Global presented the findings his company made with their MAST platform’s collision avoidance system. He invited his colleagues to experiment with their systems on the platform that he is eager to test in an environment with »real-world-uncertainty«. Axel Hahn of the University of Oldenburg stressed the need for new testing and verification methodologies for the technical, ethical, legal and insurance issues: »We need a generic test bed platform.« Jesus Mediavilla of Lloyd’s Register and his team working on the MAX- CMAS project (machine executable collision regulations for marine autonomous systems) focused on how to translate COLREGs – written for human consumption – into collision avoidance algorithms. Future work will look i.a. into interaction of autonomous and manned vessels. The difference between robot and human behaviour triggered interesting discussions in the audience, time and time again. Azriel Rahav of Totem Plus presented his holistic approach to autonomy with the Totem Auto Navigation System (TANS) that controls navigation, machinery and power. He noted: »Consider the difference between autonomous and unmanned. Also without radio contact, a truly autonomous vessel must know what to do.« He welcomed the work of Hasan Deeb of University of Oldenburg who developed a pre-crash advisor for manned vessels, that provides decision support for shipmasters for mitigating collision damage. Ideas and pro ducts like this may not be in use today and as single products they will not enable autonomous shipping – but they will be the building blocks of autonomous vessels one day. Yogang Singh and his colleagues of the University of Plymouth approached the subject of collision avoidance and path planning by looking at the possibilities of artificial potential fields Cardiff castle set the scenery for this year’s COMPIT. In 2018, the conference will take place in the Castello di Pavone, Italy Photo: Volker Bertram 68 HANSA International Maritime Journal – 154. Jahrgang – 2017 – Nr. 7

Schiffstechnik | Ship Technology Will this self-righting, solar-powered vessel one day make a successful autonomous Atlantic-crossing? The developers came up with a promising design Source: aXatlantic in real time marine environments. Tests looked promising but raised an intersting discussion in the audience on whether the manoeuvering behaviour of such a vessel would be interpreted right by human shipmasters. Although the classic shipyard topics at this year’s COMPIT were not as promiment as in the past, there were still some interesting projects on the agenda. On the software side, smart shipyard operation was a topic. Lode Huijgens of TU »Use JavaScript« Henrique Gaspar, NTNU Delft showed how a work content estimation model based on historical data and design principals could optimize the ship building process. Yong-Kuk Kim of Seoul National University addressed the issue of delays in the logistics process for ships assembled in a block construction. The tools he and his colleagues have developed integrate block logistic loads into process simulation in the planning stage to provide for a smooth production process. 100 100 95 95 75 75 25 25 5 5 0 0 100 100 95 95 75 75 25 25 5 5 0 0 Ad-Röchling-LNG-Tanks_Spports-2017 Freitag, 23.
