The TopTier joint industry project addresses cargo securing safety on container ships. The project has 40 participants; it started at the end of 2021 and is in its final year. Many aspects were covered in the project, ranging from container and lashing strength, stowage, stack dynamics, operational guidance to rules and regulations.
This paper focuses on parametric rolling ship motion. It is of key importance to know in which wave conditions large roll might occur. For this reason, seakeeping model tests were performed for a 10,000 and a 15,000 TEU container vessel. In total 190 tests in regular waves were performed and 42 tests in irregular seas (most of them with 3-hour duration). Most tests were performed in stern and bow quartering seas. Both resonant and parametric roll were studied in wave conditions around the boundary of in- and off-design motions. Together with several participants, calculations were done to compare and validate tools and their ability to predict the wave conditions in which offdesign roll motions are likely to occur. The tools are detailed and compared against each other as well as the experimental results, revealing both capabilities and challenges in the assessment of parametric rolling.
