In the frequency domain, the motion response environmental pollution. of a scaled model of a damaged very large crude oil carrier (VLCC) in In the study...

... ABSTRACT The problem for interactional flows between the ship hull and the propeller is studied by computational fluid dynamics (CFD) simulators with the RANS-based computational model. In this paper, we mainly emphasize the modelling of the propeller, by introduction of a multiple reference...

... developed rapidly, especially catamarans and trimarans. Asymmetric catamaran is a new type of high-performance ship in the early 21st century. Compared with the traditional symmetric catamaran, the so-called asymmetric ship type refers to the ship type in which the cross section of the hull forms...

... ABSTRACT This paper describes mooring analysis of deep-water semi-submersible platforms with a fully coupled method. Mooring lines, production pipelines, hulls, etc. are considered for this coupled dynamic analysis. High-strength cables have strongly non-linear properties so deep-water mooring...

... ABSTRACT In order to obtain the relativity between the propeller cavitation and hull fluctuating pressure &noise, the synchronization test of high-speed video for the model propeller of VLOC was carried out in a large cavitation channel. Propeller sheet cavitation and tip vortex cavitation...

.../unloading, power supply, personnel life and other functions. The design of a Deepwater Semi-Platform in China is still in its infancy, facing great challenges, especially for the hull piping stress analysis. Taking the hull piping of a Deepwater Semi-Platform as an example, based on CAESAR II and ANSYS...

... realizes the simulation of crushed ice slide along the hull after the ice channel broken, is established based on SPH-FEM. The numerical simulation of a carrier sailing in the narrow ice channel is carried out, of which results can well reflect the structural response of hull shoulder. Simulation results...

...). To deliver ACV and people to this region a ship will have to withstand the harsh conditions and interact with icebergs and large floating ice pieces. This interaction may result in impact type loading of a ship hull by ice, preventing a planned navigation and even causing to abort some routine operations...

... ABSTRACT Due to the acceleration of global warming, the shrinkage of the compact ice-covered area allows the ice-going ship to transport through the Polar Sea Route. Collisions, naval operations, and fatigue would potentially cause hull deformation and damage. To better improve the safety...

..., the flexibility of the hull has increased. As a result, the natural frequency decreases, and the wave encounter frequency increases during high-speed navigation. This will induce linear or nonlinear wave-induced vibration, which will seriously affect the fatigue life and navigation safety of the hull. It has...

... ABSTRACT A submarine usually consists of the main hull and appendages such as fairwater and rudders. In order to give full play to the submarine's good resistance and manoeuvrability, the SBD technique is used to optimize the shape of main hull. The six shape parameters of the main hull can...
