Timed as Planned

The on-board measurements for the “AutoPlan” (funded by BMWi; reference number 03SX523) research project on a semi-planing boat were successfully completed in the Sea of Marmara near Istanbul. In addition to the on-board measurements, the boat, built by the UZMAR shipyard, was presented to the public for the first time at a formal ceremony.

SVA Potsdam was in charge of the on-board measurements. Measurement parameters included thrust and torque measurements on both ship shafts, rudder angle measurements and pressure pulse measurements in the ship’s outer skin at a speed of approx. 27.5 knots. The test program was developed in close coordination of all partners and included autonomously driven Z-maneuvers and turning circle investigations at different rudder angles. The intensive evaluation of the measurement campaign and the comparison to the model measurements resp. simulation calculations is the task of all project partners for the next weeks and months.

The R&D project “AutoPlan – Automatic Navigation Assistance System for Planing
and Semi-planing Crafts”

The project “AutoPlan” is aimed at the safe and environmentally friendly operation of (semi) planing crafts. The issue of safety is determined by the sporadic occurrence of unstable behavior: the so-called porpoising (pitching or trimming motion) and corkscrewing behavior with rolling motions. These phenomena significantly impair the safety of people and the ship and, last but not least, pose a threat to the mission objectives also due to time delays and additional fuel consumption.

Kay Domke (SVA) appointed to ITTC’s Seakeeping Committee

Mr. Kay Domke, Division Manager Dynamics & Acoustics, has been appointed to the Seakeeping Committee of the ITTC for the 30th period of the International Towing Tank Conference. Tasks include consideration of the interim guidelines for determining the minimum propulsion power required to maintain the maneuverability of ships in adverse conditions in accordance with MEPC.1/Circ.850/ Rev.2. The Seeping Committee is composed of scientists from all continents and is primarily concerned with the behavior of ships in sea states. SVA is pleased with Mr. Domke for this honorable appointment.

Information Regarding Precautions Against the Coronavirus

Dear customers and visitors of the Potsdam Model Basin,

your health and safety as well as ours have the highest priority during this time of the coronavirus. At the Potsdam Model Basin we have taken the necessary measures and some of us are teleworking. Experiments are being conducted unhindered with all necessary hygiene requirements in place. As before the Potsdam Model Basin remains open for all urgent customer visits. We do request however that for your safety and for ours, all non-urgent or unnecessary visits should be rescheduled or conducted via teleconference. For those partners whose experiments we are conducting and who do not wish to or cannot visit us, we will document the experiments and make the results available on our FTP server using a variety of media including video.

Please ensure that you only visit the Potsdam Model Basin if you feel completely healthy, are not coming from a risk area, and that you have not had contact with an infected person. Please adhere to the relevant suggestions of the Robert Koch Institute.
