Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

Sensitivity Analysis Based on Polynomial Chaos Expansions and Its Application in Ship Uncertainty‐Based Design Optimization

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to truly reflect the ship performance under the influence of uncertainties, uncertainty‐based design optimization (UDO) for ships that fully considers various uncertainties in the early stage of design has gradually received more and more attention.

Development Of A Semi-Swath Craft For Malaysian Waters [PDF]

, 2006
Small Waterplane Area Twin Hull (SWATH) and Catamaran vessels are known to have more stable platform as compared to mono-hulls. A further advantage of SWATH as compared to Catamaran is its smaller waterplane area that provides better seakeeping ...

Ship Formation Control Using Nonlinear Model Predictive Control With Safe Speed Constraints and Tidal Elevation Variations

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
1. An adaptive speed control method is proposed to execute the ship formation trajectory tracking task more efficiently and safely while entering port with tidal elevation variations. 2. A distributed ship formation controller based on the leader‒follower structure is designed to govern the coordinated motion of formation members more flexibly. 3.

Theoretical and Experimental Study on Nonlinear Hydroelastic Responses and Slamming Loads of Ship Advancing in Regular Waves

Shock and Vibration, Volume 2018, Issue 1, 2018., 2018
Wave loads estimation and structural strength evaluation are the fundamental work at the ship design stage. The hydroelastic responses and slamming strength issues are also concerned especially for large‐scale high‐speed ships sailing in harsh waves. To accurately predict the wave‐induced motions and loads acting on the ship sailing in regular waves, a

Operability robustness index as seakeeping performance criterion for offshore vessels

Ocean Engineering, 2020
Abstract The offshore industry operates increasingly large installations in exposed areas requiring high reliability and availability. Downtime of complex offshore systems leads to significant financial losses. Towards year-round offshore installation and maintenance service, this research focuses on the identification of weather-robust vessel ...
