Subsea Service Support Infrastructure Lifecycle support for subsea operations. LEARN MORE Improve your well control There are many factors that affect maintaining a secure operating envelope during landing string operations, including well flow conditions, water depth, and vessel motion. Even under perfect conditions, this is a complex job. But what happens if an incident occurs, such as a dynamic positioning or anchor system failure? In emergency situations, our landing string system gives you more control when you need it. Leveraging the SenTURIAN Family systems in conjunction with the SenTREE subsea test tree systems, the landing string disconnects from the wellhead in 15 seconds, providing a dual barrier of protection that safely closes in the well and retains all the contents of the riser to prevent spillage. The landing string can also be reconnected quickly when conditions return to normal.
