HOUSTON – McDermott International Inc. has completed the final offshore campaign for the INPEX-operated Ichthys LNG project offshore Western Australia.
This was the second of two remaining work packages left underMcDermott’s contract, which was the largest subsea contract ever awarded at the time. Most of the EPCI for the SURF contract awarded in January 2012 was completed by the end of 2017.
The final offshore campaign involved subsea tiebacks to new drill centers and was executed by the company’sLay Vessel 108 (LV 108). The vessel has recorded 813,694 hours without any lost time incidents since its first campaign in 2015, McDermott said.
McDermott recorded more than 500,000 engineering workhours from offices across the world, including a Perth-led project management team that was in place from 2012 and consisted of 160 personnel at its peak in 2017; procured more than $600 million in-field equipment; built 48 subsea structures weighing a total of approximately 28,660 tons (26,000 metric tons) that included one of the largest riser support structures in the world at the time; and used three of the company’s deepwater installation vessels (DLV 2000, LV 108, and Intermac 650) and other contracted vessels to execute the project.
The company has a small fabrication scope remaining to be completed at its fabrication yard in Batam, Indonesia, which will conclude its work packages for the Ichthys LNG project in its entirety in 2019.
