2,000,000 lb. Landing String Developments: Novel Slipless Technology Extends the Deepwater Operating Envelope
This paper pertains to the technological development of a completely integrated landing system that provides the ability to extend the deepwater drilling and completion envelope. This system is comprised of an elevator, slipless spider, and landing string all specifically designed to land heavy casing strings in deepwater wells thus overcoming the load limitations of conventional equipment. All stages of evolution are analyzed including research, development, design, verification testing, manufacturing, proof testing, running, handling, and actual case histories detailing field use.
