Description
Bolong Zhou and co-authors develop in 2024 real-time estimation methods for a trailing suction hopper dredger. The ship sucks seabed sediment into a hopper, where it settles. Settling depends on average sand grain size, which shifts during loading and is hard to measure directly.
They test several particle filter methods on a simplified settling model with simulated loading data. Targets include grain size, sand bed height, and sand bed mass. One feedback filter method gave the best accuracy and speed. It was then applied to a real vessel, with its starting grain size set by a search algorithm.
