A simplified method of performing fatigue analysis of offshore structures

A simplified method of performing fatigue analysis of offshore structures   Introduction An offshore structure is subject to environmental loads of waves, wind and current. By their nature, the resulting wave loads on the structure are cyclical. These cyclical...

How to use a ship’s hydrostatics to calculate its draft and trim

Introduction A ship’s hydrostatics, or hydrostats, is an oft used term in maritime parlance, and it refers to the characteristics when it is floating. What characteristics are these? How are these determined, and how can we read and understand them? Understanding...

Numerical integration methods for hull volume estimation

Introduction The hull of a ship is a complex 3D geometry, and finding out its simple properties like volume, centroid, etc. is not possible through simple formulae unlike standard shapes like cuboid or a cylinder.   How do we find a property, say the volume of a...
