Bayou Bend CCS LLC has commissioned subsea service pror Geo Surveyvider Sulmara to conduct an archaeological and geohazard assessment of the proposed Bayou Bend pipeline route from landfall to future offshore platform locations.
Sulmara employed an electric WAM-V 16 uncrewed surface vessel (USV) for the high-resolution geophysical survey at the Bayou Bend carbon capture and storage (CCS) project, which helped “significantly lower” the overall carbon footprint of the project by reducing the number of diesel-burning vessels offshore, as well as shortening the time required to conduct the survey, the company said in a news release.
Sulmara Project Manager Darius Rivera said, “The quality of the data gathered is some of the best we’ve seen from a USV. That quality of information, as well as the operability of the equipment and [the] relationship that has been developed, have been key to the project’s success”.
“Launching the USV proved challenging given the time of year with the higher winds and seas. However, I am delighted we were able to overcome these issues and provide Bayou Bend CCS with such valuable data.” Rivera added.
The project took advantage of the SpaceX-backed Starlink satellite system to ensure strong communications between the shore and the USV, according to the release.
“With the survey area around [15 kilometers] from shore, we integrated the WAM-V with Starlink to achieve higher speed communications with the mobile remote command center,” Rivera said. “This is the first time we have been able to go beyond the [three kilometer] mark with this size USV, ensuring improved quality of data and reducing the time needed to collect the information when compared to a conventional survey vessel”.
Andy Nicol, Sulmara Regional Director for the Western Hemisphere, said, “We are proud to partner with Bayou Bend CCS on this important project. Our development of towed sensor capability from an uncrewed platform is a clear demonstration of our commitment to both sustainability and innovation”.
Bayou Bend is a joint venture owned by Chevron, Talos Energy and Equinor to develop a CCS facility in Southeast Texas. According to the joint venture’s website, the project is the first offshore stratigraphic well for carbon capture and storage in U.S. state waters and has the potential to reduce emissions from regional industrial facilities by sequestering carbon dioxide (CO2) safely and permanently underground.
In March, TotalEnergies E&P USA, Inc. announced the acquisition of 100 percent of Talos Low Carbon Solutions (TLCS) from Talos Energy Inc. for $125 million plus customary reimbursements, adjustments and retention of cash, combined totaling approximately $148 million.
Upon closing of the transaction, TotalEnergies will own a 25 percent share in the Bayou Bend project, which is close to its assets in the region, the company said in an earlier statement. Bayou Bend is operated by Chevron with a 50 percent stake, while Equinor owns a 25 percent stake.
The Bayou Bend project is a carbon transportation and storage solution for industrial emitters located in the Houston Ship Channel and Beaumont – Port Arthur region, one of the largest industrial corridors in the USA.
Sulmara, formed in 2019 and employing more than 200 people worldwide, said it has grown rapidly to become an international services provider with offices across the Americas, Europe, and Asia.
