| Abstract: | Meeting the world’s energy demand increasing requires the development of remote gas resources. Long distance gas transmission pipelines traversing challenging environments are needed to bring new gas supplies to the markets where they are needed. These pipelines can cost billions to tens of billions of dollars. ExxonMobil has developed high strength pipeline steels with yield strength of 120 ksi (X120) to reduce the cost of long-distance gas pipelines by 5 - 15%. To enable construction of these high strength pipelines, welding technology capable of producing high strength and toughness needed to be developed. This presentation describes the girth welding development program. |

Bio: | Mario Macia graduated from Rice University with a BS in Materials Science and Engineering in 1991 and then from the Georgia Institute of Technology with a PhD in Materials Science and Engineering in 1996. He joined ExxonMobil Upstream Research Company (URC) in 1996. During his time at ExxonMobil, he research has focused on development of materials and design technologies for challenging pipelines. Research topics have included the development of high strength steel linepipe, high strength steel welding technology, pipeline design for arctic and seismic environments and fatigue design of risers for deepwater floating structures. Currently, he is serving as the Materials & Fabrication team lead in the Offshore, Arctic and Pipeline Division. |
