Tieback
From Wikipedia, the free encyclopedia
Tieback may refer to:
- Tieback (geotechnical), a method of supporting retaining walls
A tieback is a loop of cloth, cord, etc, which is placed around a curtain to hold it open to one side. Typically, a tieback will be passed through a ring on a hook attached to the wall, and fastened with a knot, button or velcro. They are often adorded with tassels.
In journalism a tieback is a newspaper rewrite. It usually consists of a few paragraphs which contain a short synopsis of the information presented in the original story. The chief purposes of a tieback are to refresh the memories of readers who saw the old story and to update new readers.
Subsea tiebacks connect new discoveries to existing production facilities, improving the economics of offshore oil and gas production and transforming marginal fields into profitable assets. Indeed, at a time when many of the world's major offshore oil and gas fields are reaching maturity, new discoveries tend to be smaller – and therefore more challenging to exploit in a cost-effective manner. Many companies are pushing forward the technology of subsea tiebacks to produce more oil and gas at a lower cost, over longer distances and in deeper waters. Deployment of subsea tiebacks maximizes the life of existing production infrastructure.
