When a ship navigates through ice-covered seas, the interaction between sea ice and
propellers damages the propeller blades. A coupled discrete element method (DEM)-finite …

The propeller fluctuating force is being recognized as the dominant source of underwater
radiated noise, its accurate acquisition is thus necessitated for a reliable acoustic-structure …

The reliability of marine propulsion plants of ice-going vessels is essential in preserving ship
safety during ice navigation. Therefore, the development of reliable design tools of the …

It is necessary to quantify the loads experienced by the propellers of ice-going vessels.
Knowledge of these loads will serve to improve propulsion design specifications and …

It is a key issue to investigate the degradation law of ship propeller service performance and
predict its residual fatigue in marine engineering. In this paper, the underwater test are …

During ship operations in ice-covered waters, propellers often collide with sea ice pieces.
This phenomenon represents a severe hazard that affects the torsional stress state of …

During navigation in Polar regions, ice-induced torque excitation endangers the operation
and integrity of ship propulsion systems. Predicting these dynamic phenomena through …

To date, the insufficient quantification of ice-induced propeller moments leads to uncertainty
and over-design of ship propulsion systems. Recent developments document the use of …

Accurate quantification of propeller excitation is essential for effective vibro-acoustic analysis
and mitigation in marine vessels. This study introduces a Bayesian statistical framework that …

When a propeller works in an icy environment, the persistent external ice forces can induce
deformation at the blade tips of the propeller, which may lead to damage or significant …
