Arconic’s titanium stress joints deliver strength, reliability for deepwater operations

“Titanium stress joints have to be engineered and manufactured to meet very tight tolerances, so we relied on Arconic’s engineering expertise to deliver the right solution.”

Touted as one of the most ambitious oil and gas production systems in the Gulf of Mexico, LLOG’s Delta House development relies on proprietary Arconic Energy Systems’ technology—titanium stress joints (TSJs) that connect system components—to deliver strength, reliability and weight savings in the harshest deepwater environments.

Designed to deliver a peak capacity of 100,000 barrels of oil and 240 million cubic feet of gas per day, the Delta House production system taps three fields where the average water depth tops 4,500 ft (1,372 m) and reservoirs range from 12,000 to 18,500 ft (3,658 to 5,486 m). To connect the massive production risers to the floating host platform, LLOG needed pliant joints strong enough to support the weight of the risers and withstand current and wave action, while also performing reliably with minimal maintenance for 20-plus years.

Arconic’s TSJs delivered a cost-effective solution. TSJs provide a more reliable and compact alternative to rubber flexible joints and steel tapered stress joints, making them easier to install and compatible with more design options. And titanium is twice as strong as steel, more flexible and provides better fatigue resistance.

Our initial collaboration on the Delta House platform was so successful that LLOG subsequently purchased additional TSJs which are slated to tie Delta House to the La Femme, Blue Wing Olive and Red Zinger oil fields and take production from four more wells by the end of 2018.

Where will Arconic’s TSJs go next? When it comes to our innovative solutions for deepwater oil and gas exploration, the sky might be the limit—but the ocean depths are not. In addition to TSJs, Arconic is also the leader in lightweight aluminum drill pipe and other multi-material solutions for extended reach drilling.
