New structurally optimised jacket design

Decorative image New

Chet Morrison Contractors (Morrison) of the US has formed a strategic partnership with iSIMS to launch the iJacket, a new optimised method in jacket and foundation design.

The patented design is claimed to be more structurally optimised than a conventional true X-braced jacket design, supporting the same deck load, conductor/riser count, drilling deck, wind turbine or other payload as its conventional counterpart. It is also claimed to offer cost savings and reduced material and labour requirements over traditional foundations and jackets by up to 30%.

The iJacket’s lower weight and reduced footprint is said to make transport and offshore assembly quicker and more economical, with its shape and design allowing for more optimised cargo arrangement and less barge transportation costs, according to the companies. Furthermore, a more open design ensures the jacket is 100% ROV and AUV accessible, eliminating the need for divers to carry out inspections.
