On operation capabilities analysis of a 100000 tdw tanker by seakeeping criteria

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2019
The operation capabilities of a maritime ship have to be assessed during the design, including the seakeeping criteria. In this study a 100000 tdw tanker is considered, with two loading conditions, cargo and ballast.

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 ...

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.

Fatigue Strength Assessment of Trimaran Cross‐Deck Structure Based on Spectral and Simplified Fatigue Method

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In order to investigate the fatigue behaviour of trimaran cross‐deck structural details, the spectral and simplified fatigue analysis approaches are proposed. In spectral fatigue approach, three‐dimensional (3D) linear potential flow theory and global FE analysis are used for wave loads and stress transfer functions calculation; the stochastic spectral

Wave effects on the turning ability of an ultra large container ship in shallow water [PDF]

, 2019
The influence of waves on ship behaviour can lead to hazardous scenarios which put at risk the ship, the crew and the surroundings. For this reason, investigating the effect of waves on manoeuvring is of relevant interest.

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.

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.

CFD Prediction of Ship Seakeeping and Slamming Behaviors of a Trimaran in Oblique Regular Waves

Journal of Marine Science and Engineering, 2021
The main hull encounters waves at first and causes waves to break, when trimarans are subject to the slamming in head waves. At this moment, emergence phenomena of side hulls will not occur. Thus, the slamming study of trimarans in oblique waves presents

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
