Roll motion response analysis of damaged ships in beam waves

Fast Prediction for Damaged Ship Roll Motion in Waves by an Aggregation Model based on GA

“…However, the problem of motion response prediction for damaged ships is rarely discussed. This study applies machine learning to predict ship motion response based on the damaged standard DTMB5415 [3,4]. The evaluating estimator performance is adopted to ensure the accuracy and stability of model prediction.…”

Anti-Roll Characteristics of Marine Gyrostabilizer Based on Adaptive Control and Hydrodynamic Simulation

“…These lead to continuous swaying motions of ship, including roll, pitch and yaw. These irregular undesirable motions always have adverse effects on the stability, seakeeping and resistance characteristic of ship [1,2], which will eventually affect the safety of navigation, anchoring and operations of ships, as well as the cargo stowage, the comfort of occupants and the normal operation of mechanical equipment [3]. The damage caused by ship roll needs special attention, especially for the special ships with high stability requirements, such as military ships, crane ships, passenger ships and rescue ships [4].…”

Thrust Enhancement of Dtmb 5415 with Elastic Flapping Foil in Regular Head Waves

“…In real sea conditions, marine craft experience undesirable wave-induced oscillatory, heave, and pitch motions. These will affect the stability of ships [1] and increase ships' resistance in navigation [2,3]. Historically, foils have been investigated either as antipitching fins on ships [4][5][6] or for propulsion in a wavy flow [7][8][9][10][11].…”
