Effects of Forward Speed and Wave Height on the Seakeeping Performance of a Small Fishing Vessel

open access: yesJournal of Marine Science and Engineering, 2022
The effects of wave height and forward speed on the seakeeping performance of a small fishing vessel in irregular waves are evaluated using computational fluid dynamics (CFD).

SEAKEEPING OF A FAST DISPLACEMENT CATAMARAN

open access: yesTRANSPORT, 2005
The paper presents a complex method for the calculation of pitch and heave of a fast displacement catamaran. It incorporates speed factors, interference of catamaran hulls, stabilization factors and possibility to apply different stabilization cases including a stabilizer activation possibility.

Damage stability of ships as a safety criterion for optimisation tools

open access: yes, 2006
A literature overview of past optimisation studies revealed that whilst satisfaction of intact stability requirements has been built into existing alternative hull form optimisation packages, seeking improved hydrodynamic hull forms in terms of ...

Numerical study of Iran-Bushehr Container Ship motions and added resistance in regular head waves using STAR-CCM+

open access: yesنشریه مهندسی دریا, 2020
Nowadays, the optimal use of energy, speed increase, fuel consumption reduction and environmental pollution prevention are essential in the ship design and manufacturing discussion. So it is critical to be able to estimate ship's response to waves, since

The hydrodynamic and dynamic motion analysis of a damaged ship

open access: yes, 2008
The hydrodynamic analysis and motion response of a damaged ship requires a novel generalisation of the methodsnormally applied to intact ships or other floating structures. Damaged ship statistics are used to provide likely damage scenarios.

CFD-Based Hydrodynamic and Operability Assessment of a CB90-Derived Multipurpose High-Speed Craft

open access: yesJournal of Marine Science and Engineering
This study evaluates the hydrodynamic and operability characteristics of a multipurpose high-speed craft derived from the CB90 through stern-region refinement. Calm-water performance was assessed using unsteady Reynolds-averaged Navier–Stokes simulations
