Investigation on Fitting Method of Snail Structural Lines

For the current status of the spudcan design and combining the characteristics of bionics, on the basis of shells on the solid model, the paper study the spiral geometry characteristics and distribution. Regarding the shape of the surface characteristics of the spiral portion and snail shells spiral suture lines, a feature reverse scan statistics can be made. Snail shells overall shape evaluation can be established and micro-element methods are used to deduce the 2D mathematical expression so as to provide a good reference for the design of jack-up platform spudcan.
