Landing String Solutions L.L.C. Information

Landing String Solutions (LSS) Buoyed Landing String (BLS) system was developed to ensure operational safety due to deeper and more complex well designs. Operators recognize the operational and design challenges associated with these complex wells and are aggressively seeking new technology and innovative methods of reducing the continuing cost increases associated with deepwater drilling / development wells. The BLS system substantially increases the margin of safety to a rig’s existing hoisting system without the need for expensive upgrades. This system, patented by LSS, is attached to the heavy casing’s landing string. It is custom designed to match a well’s existing operating parameters and is engineered to deliver a desired string weight reduction. The actual amount of weight reduction achieved is dependent on the length of the riser and mud weight density in the well. Hook load weight reduction in some cases may be as much as 90% of the landing string weight or about 400,000 pounds depending on water depth, mud weight and an optimized configuration of the system’s available module densities.
