Chet Morrison Contractors, an energy service company for the oil, gas and renewables industries, has formed a strategic partnership with iSIMS to launch a new optimized method in jacket and foundation design.
The patented iJacket is more structurally optimized than the 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, the developers said. The design is engineered to provide significant cost savings and reduce material and labor requirements over traditional foundations and jackets by up to 30 percent.
Greg Detiveaux, vice president business development, Morrison, said, “The modular nature of the iJacket dramatically reduces time and energy spent fabricating and makes available a wider choice of fabrication locations.
“Its lower weight and reduced footprint makes transport and offshore assembly quicker and more economical than ever before, with its shape and design allowing for more optimized cargo arrangement and less barge transportation cost.”
Modern 3-D engineering design and analytical tools allow engineers to design and arrange bracing in a configuration that offers further structural optimization, while still meeting or exceeding the industry design requirements for strength and fatigue performance.
“A more open design ensures the iJacket is 100 percent ROV and AUV accessible, which eliminates the need for divers to carry out inspections,” Detiveaux said.
DNV GL has awarded iSIMS with an Approved in Principle (AiP) for the iJacket design method and Morrison is the exclusive fabricator for North America, Mexico, the Caribbean and the north coast of South America.
