These events are known to induce some of the most severe design loads, but are very poorly predicted using current industry standard techniques. The complex fluid-structure interactions can be modelled using coupled CFD and FEA, but the ship's dynamic response is highly nonlinear and must therefore be solved in the time domain.

GOAL-BASED NEW SHIP CONSTRUCTION STANDARDS Status reports .

should be based upon the specified design life. The net scantling assumption is a crucial design parameter for many different areas in the rules and needs therefore to be supported with justification as requested by 3.2.3.2. Sufficient justification for the net scantling approach with regard to hull girder strength has not been found.

Causes and Effects of the Rapid Sinking of the Titan

Like a giant lever, the hull plates transferred the inward forces, applied to the edges of the cracked plates by the water rushing into the hull, to the rivets along the plate seams. The rivets were then either elongated or snapped in two, which broke the caulking along the seams and provided another inlet for water to flood the ship. Design Flaws

Naval Architecture with Ocean Engineering BEng .

In second year, students take part in the design and build of a small-scale racing yacht. This combines the use of professional Naval Architecture design software for hull design and computer-aided manufacture for hull generation. This is combined with hands-on practical skills and hydrodynamic testing.

Best Master's Degrees in Naval Architecture 20

Generally consisting of advanced studies in the science of ship design, including modeling and testing, as well as a thorough understanding of related principles such as fluid dynamics, a master's degree in naval architecture prepares students for success in maritime industry positions.

Naval Architecture | S

Topics include: static equilibrium of ship hull girder, still water and wave loads on ships; calculation of load effects on ship hull girder, bending and shear stresses in ship hull girder, calculation of cross-sectional properties of ship buckling of columns, truss structures and statistical analysis of stress time series.

Intact stability analysis of dead ship conditions using FO

the occurrence of the stipulated wave and wind forces. Other interesting studies along the same lines have been published, e.g. Paroka et al. (2006). Reliable statistics of capsize in dead ship conditions require long time domain simulations. This can be very time consuming when a detailed hydrodynamic model is applied.

Icebreaking ships are a relatively new evolution in the history of ship design and construction. Conventional ships in or near ice-covered waters from the earliest years of recorded history had to do their best to avoid the ice. If they failed, they risked being trapped in ice with the potential ...

A Method for the Quantitative Assessment of Performance of .

Overall bending of a ship’s hull girder is a very important failure mode, which is normally catastrophic and has severe consequences. It is thus of great importance to accurately predict the ultimate strength of hull girders so that an adequate but not excessive safety margin for this failure condition can be ensured at the ship design stage.
