Application of NASTRAN/COSMIC in the analysis of ship structures to underwater explosion shock [PDF]

The application of NASTRAN/COSMIC in predicting the transient motion of ship structures to underwater, non-contact explosions is discussed. Examples illustrate the finite element models, mathematical formulations of loading functions and, where available,

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 ...

Ship Motion Parameter Estimation and Refocusing Method Based on Minimization of Position Offset in Multiview Missile-Borne SAR Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Motion compensation helps mitigate the defocusing effects observed in ship synthetic aperture radar (SAR) images caused by ship’s noncooperative motion, and its effectiveness depends on the accuracy of motion parameter estimation.

Ship motion estimation

, 1967
This thesis proposes a method of identifying the dynamics of ship angular motion at sea as the basis for ship motion estimation. Various sources of information are discussed. A digital model to simulate ship's motion is developed. Identification algorithms are presented with the results of thei stochastic digital simulation.

The Use of Pivot Point in Ship Handling for Safer and More Accurate Ship Manoeuvring [PDF]

, 2011
The size of ships has increased notably over recent decades. The size of harbours and ports has however not grown in proportion. As a result ship manoeuvring in harbours and ports has become more problematic, and more of an art than a science.
