Item type:Publication, Access status: with files , Strain-gauge-based measurements of ice loads on ships(2018); Design loads are a central element of ship construction, because they influence plate and frame thickness. For the construction of ships that are destined to navigate in cold areas, it is extremely important to take into account the loads of ice impacts and their location on the hull. But ice is a particularly inconsistent material. To measure ice-induced loads, a lot of measurement has been undertaken, many of them used strain gauges. However, long-term strain gauge measurements are rare. In this bachelor’s thesis the state-of-the-art strain-gauge measurements are to be reviewed and problems with strain-gauge measurements will be discussed. Suggestions for improvement on problems like long cable complexity, big measurement setup, complicated installation, external power supply and long-term maintenance by humans while measuring will also be submitted. Therefore, different systems and measurement possibilities should be compared in the context of long-term strain gauge measurements. A feasible solution for the mentioned problems, but also to identify the location and force of ice impact, will be designed.Publicationtype: Bachelor Thesis374 1569 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Squat computations for container ships in restricted waterways(Curran Associates, Inc., 2011); ; ; ; The paper presents results of dynamic squat computations in restricted waterways with two potential flow solution methods and a solver of Reynolds-averaged Navier-Stokes equations (RANSE). Computational results are compared with model tests and full-scale measurements for two large post-panamax class container carriers. Ways of computational time reduction are discussed.Publicationtype: Conference Paper42
