TLDR
In this article, a dynamic model of a ship-mounted container crane (called the "mobile harbor") subject to the motions of ship itself imparted by random sea waves is investigated, and the condition of the sea is assumed to be State 3.About:

Neural Network-Based Adaptive Antiswing Control of an Underactuated Ship-Mounted Crane With Roll Motions and Input Dead Zones
TL;DR: A neural network-based adaptive control method that can provide effective control for both actuated and unactuated state variables based on the original nonlinear ship-mounted crane dynamics without any linearizing operations is designed.

Nonlinear Stabilizing Control for Ship-Mounted Cranes With Ship Roll and Heave Movements: Design, Analysis, and Experiments
TL;DR: This is the first closed-loop scheme that can achieve asymptotic control results, without linearizing/approximating the original nonlinear dynamics when performing controller design and stability analysis, for underactuated ship-mounted cranes with ship roll and heave movements.

Vortex-induced vibrations and control of marine risers: A review
Keum-Shik Hong,Umer Hameed Shah +1 more
TL;DR: In this paper, a review of the dynamics and vibration control techniques for marine riser systems is presented, where the riser pipes are modeled as Euler-Bernoulli beams that vibrate under the effects of ocean loads and the movements of the surface vessel, resulting in hybrid ODE-PDE equations.

Sea Loads on Ships and Offshore Structures
TL;DR: In this paper, linear-wave induced motions and loads on floating structures were modeled as Second-order nonlinear problems. But the authors did not consider the effects of the wind and current on the floating structures.

Principles of dynamics
TL;DR: In this article, the Lagrange Equations are used to model the dynamics of a rigid body and a system of parts of a particle system with respect to the velocity of a single particle.
Ship motions and sea loads
TL;DR: In this paper, a new strip theory is presented for predicting heave, pitch, sway, roll, and yaw motions as well as wave-induced vertical and horizontal shear forces, bending moments, and torsional moments for a ship advancing at constant speed with arbitrary heading in regular waves.

Nonlinear coupling control laws for an underactuated overhead crane system
TL;DR: In this article, a simple proportional-derivative (PD) controller is used to asymptotically regulate the overhead crane position and the payload angle, and two nonlinear controllers are presented to increase the coupling between the planar gantry position and payload angle.
