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.

Receive turnkey subsea landing string services backed by our experience and expertise

From completion to testing, each of our service engagements include a dedicated project manager that works with you to understand your objectives and is a single point of contact available to you at any time during the service. Project managers bring the full technical breadth and expertise of the Schlumberger organization with 24/7 access to our global network of technical experts.

All of this amounts to a seamless and turnkey experience that keeps you in the know at every stage of service delivery and gives you the peace of mind that the job will be done right.

Minimize your exposure to HSE risks with our subsea landing string crews and equipment

Highly efficient crews receive rigorous cross-training in our systems and standardized processes. This not only enables us to better control the quality of our service and reduce logistics requirements on any project anywhere in the world, but it also helps to reduce our crew footprint on your rig when combined with other services.

At every stage, we also want you to have complete confidence that not only our people but also our equipment will protect your operations and the environment from harm. We accomplish this by tracking each piece of equipment from cradle to grave to ensure all the equipment we use is certified and proven reliable.

Our goal is simple. We want to provide you with a better way to connect to your reservoir that involves less exposure to HSE risks and keeps your crew and the environment safe.
