In the challenging environment of the Gulf of America, Vulcan Offshore (TVO) once again demonstrated its technological innovation capabilities by completing the installation of a TBOP (Tethered Blowout Preventer) system specifically adapted to soft-seabed subsea conditions.
The operation, carried out at nearly 4,000 ft depth, aimed to address the high fatigue load on the well system caused by seabed instability. To tackle this, TVO customized its Hercules™ TBOP system, a technology designed to stabilize floating platforms using moorings anchored to the ocean floor.
Technology adapted to extreme conditions
The Hercules™ TBOP system uses four polyethylene mooring lines connected to suction-pile foundations to stop movement of the blowout preventer (BOP) stack above the wellhead, transferring loads to the moorings and the seabed. This significantly reduces cyclic stresses on wellheads and extends their service life.
Originally created to allow deepwater platforms to operate in shallower areas with dynamic positioning systems, Hercules has evolved to suit each operating environment. Its flexibility was key to making this new adaptation work under the Gulf’s unpredictable conditions.
In this project, the mooring system made it possible to install the BOPs directly on the platform, maintaining stability during critical operations. This solution reduced operational risk and enabled the well to be successfully completed, even under conditions of high geotechnical vulnerability.
Global experience with proven results
For more than a decade, Vulcan Offshore has been a key player in improving offshore safety and solving complex technical challenges. Its technology has been deployed in multiple regions, including the North Sea, Australasia, and South America, strengthening its reputation as a trusted provider of specialized engineering.
With this new installation, TVO reaffirms its leadership by adapting high-end technology to seabed realities, setting a precedent for preventing structural failures in wellheads in extreme environments.
