CFD Investigation into Seakeeping Performance of a Training Ship [PDF]

CFD Letters, 2021
The numerous ship accidents at sea have usually resulted in tremendous loss and casualties. To prevent such disastrous accidents, a comprehensive investigation into reliable prediction of seakeeping performance of a ship is necessarily required. This paper presents computational fluid dynamics (CFD) analysis on seakeeping performance of a training ship

Comparative seakeeping performance analysis of a warship [PDF]

, 2011
A successfully designed ship is expected to fulfill her mission in almost all weather and sea states without compromising her safety. This is particularly important for a warship and crew onboard to be able to perform their complex tasks in good physical and mental state.

Efficient seakeeping performance predictions with CFD

, 2019
Tack vare den stadigt ökande beräkningskraften kan beräkningsuiddynamik (CFD) idag användas på beräkningsintensiva problem som sjöegenskapssimulationer. Den här rapporten undersöker användning av CFD på sjöegenskapsprestanda och syftar till att foreslå ett best-practice förfaringssätt för effektiv sjöegenskapssimulationer.

Computational Investigation of Seakeeping Performance of a Surfaced Submarine in Regular Waves

한국해양공학회지, 2022
A submarine is optimized to operate below the water surface because it spends most of its time in a submerged condition. However, the performance in free surface conditions is also important because it is unavoidable for port departure and arrival ...

Numerical Study of the Effect of Angle and Location of the First and Second Steps on the Performance of Planing Hull and Their Optimization Using the Taguchi Statistical Method

Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023
Providing steps at the bottom of a high‐speed craft could decrease the resistance and enhance the longitudinal stability by dividing a single pressure hump into several ones and extending the hydrodynamic pressure towards aft of the vessel. In the present paper, the effects of the fore and aft steps’ locations and angles on double‐stepped hulls are ...

Expediting recovery of autonomous underwater vehicles in dynamic mission environments: A system‐of‐systems challenge for underwater warfare

Journal of Field Robotics, Volume 39, Issue 8, Page 1323-1340, December 2022., 2022
Abstract As autonomous underwater vehicle (AUV) adoption increases, operators demand advanced behaviors from commercial off‐the‐shelf systems. However, new behaviors can often only be deployed operationally once assured. This paper overviews research into expediting recovery to an operator's vessel through a custom homing behavior, demonstrating ...

Autonomous hanging tether management and experimentation for an unmanned air‐surface vehicle team

Journal of Field Robotics, Volume 39, Issue 6, Page 869-887, September 2022., 2022
Abstract The mission of an unmanned air vehicle (UAV) tethered to a small unmanned surface vehicle (USV) is considered. As opposed to the majority of existing tethered UAV work, which assumes a taut tether, this paper addresses the challenge of tether management for a slack, hanging tether in a dynamic ocean environment up to sea state 4 on the Douglas

Modal Investigation on a Large‐Scale Containership Model for Hydroelastic Analysis

Shock and Vibration, Volume 2022, Issue 1, 2022., 2022
A 20,000 TEU containership with an overall length of about 400 m is designed as a target ship to investigate ship hydroelastic characteristics in the joint industry project (JIP) of CSSRC‐20,000 TEU. A set of systematic model tests are carried out in the seakeeping wave basin of CSSRC.
