Slant leg jack-up rig increases water depth

摘要

A new patented method of using slanted legs in current jack up rigs could result in increased stability and allow them to work in greater water depths. It could also reduce the size of newbuild deepwater jack-up designs. Many platforms are built with the upright sides set at a 10deg 'batter' which gives a greater footprint in the subsea than the end adjoining the topsides. This provides an inherent increase in stability over strictly vertical sided structures.
