Study of Two Ships Approaching Process and Towing Motion under Wave Action
Journal of Marine Science and Engineering, 2022 The rescue of ships in distress at sea relies mainly on rescue vessels, which includes the approaching process and the towing motion of the two ships. Ship rescue can be reduced to a two-ship problem, primarily involving the relative motion between ships

Optimal Universal Controllers for Roll Stabilization [PDF]
, 2020 Roll stabilization is an important problem of ship motion control. This problem becomes especially difficult if the same set of actuators (e.g. a single rudder) has to be used for roll stabilization and heading control of the vessel, so that the roll ...

Sea State Monitoring by Ship Motion Measurements Onboard a Research Ship in the Antarctic Waters
Journal of Marine Science and Engineering, 2021 A parametric wave spectrum resembling procedure is applied to detect the sea state parameters, namely the wave peak period and significant wave height, based on the measurement and analysis of the heave and pitch motions of a vessel in a seaway, recorded

Dynamic Interaction of a Heavy Crane and a Ship in Wave Motion [PDF]
Modeling, Identification and Control, 2018 Previous work on the dynamics of vehicle-manipulator systems is extended to offshore ships with heavy cranes. The proposed method is based on a Newton-Euler formulation where the forces of constraint are eliminated using projection matrices based on the ...
