Influence of initial heeling angle on ship roll motion response

open access: yesZhongguo Jianchuan Yanjiu, 2022
Objectives In this work, the influence of the initial heeling angle on the roll motion response of a ship in random beam wave is studied. MethodsSpecifically, the path integration method is applied to solve the Fokker-Planck equation, which governs the ...

An approach to high speed ship ride quality simulation [PDF]

open access: yes, 1975
The high speeds attained by certain advanced surface ships result in a spectrum of motion which is higher in frequency than that of conventional ships.

Roll reduction and course keeping for the ship moving in waves with factorized NGMV control [PDF]

open access: yes, 2015
A factorized Nonlinear Generalized Minimum Variance (NGMV) control law is developed for a combined roll and yaw motion compensation using rudders and fins. The nonlinear model used for control design includes the non-minimum phase interaction from rudder

Dynamical Models of Extreme Rolling of Vessels in Head Waves [PDF]

open access: yes, 2009
Rolling of a ship is a swinging motion around its length axis. In particular vessels transporting containers may show large amplitude roll when sailing in seas with large head waves.

The influence of ship motion of manual control skills [PDF]

open access: yes, 1981
The effects of ship motion on a range of typical manual control skills were examined on the Warren Spring ship motion simulator driven in heave, pitch, and roll by signals taken from the frigate HMS Avenger at 13 m/s (25 knots) into a force 4 wind.

Experimental investigation of wave-induced motions of an obliquely moving ship [PDF]

open access: yes, 2008
The lateral drift appears due to the effects of wind forces and/or wave drifting forces for a ship sailing in actual sea. The effects of wind forces and / or wave drifting forces in views of lateral drift for ship moving with certain forward speed have ...

Control of Ship Roll Motion [PDF]

open access: yes, 2014
The undesirable effects of roll motion of ships (rocking about the longitudinal axis) became noticeable in the mid-nineteenth century when significant changes were introduced to the design of ships as a result of sails being replaced by steam engines and the arrangement being changed from broad to narrow hulls.

A Novel Short-Term Ship Motion Prediction Algorithm Based on EMD and Adaptive PSO–LSTM with the Sliding Window Approach

open access: yesJournal of Marine Science and Engineering, 2023
Under the influence of variable sea conditions, a ship will have an oscillating motion comprising six degrees of freedom, all of which are connected to each other.

Using piloted simulation to measure pilot workload of landing a helicopter on a small ship [PDF]

open access: yes, 2017
When conducting landings to a ship's deck in strong winds, helicopter pilot workload is often dominated by the turbulence within the ship's airwake. Previous studies have shown that larger ships create more aggressive airwakes and simulated flight trials

PERANCANGAN KAPAL UNTUK MENUNJANG KEGIATAN PARIWISATA DI WADUK JATILUHUR, PURWAKARTA

open access: yesKapal, 2012
Jatiluhur had the very big tourism potency so that it was required the supporting mean such as the tour ship which was better than the wooden ship. The research about the tour ship design having a catamaran hull form was expected to help the development ...
