tiebacks

The motto of the Olympic Games is “Citius, Altius, Fortius,” Latin for “faster, higher, stronger,” which emphasizes the concept of pushing the limits. As an engineer, that approach really speaks to me—and offshore installations, and especially offshore tiebacks, illustrate that concept very well.

Eni conducted a research project to explore the maturity of new technologies to enable economical development of deepwater prospects with tieback distances longer than 50 km and 150 km, respectively, for oil and gas fields.

Subsea advancements in the works include longer tiebacks, an underwater drone that lives on the seafloor, and a robotic manifold capable of actuating dozens of valves. Do these new capabilities, born of necessity, signal a sea change in industrywide technology development?

The complete paper presents and discusses the authors’ technology-development program regarding very-long oil-tieback architectures (50–100 km) and enabling technologies.

When two engineers lost their jobs during the industry downturn, they used the misfortune as an opportunity to develop an innovative concept that aims to make it a lot easier to move subsea gas long distances.

Anadarko aims to maximize immediate short-cycle value through tiebacks and platform relocations in the Gulf of Mexico.

This paper focuses on cementing-design challenges and discusses the engineering techniques used to approach them.

Linhua4-1 was China’s first tieback subsea development project. To develop this marginal oil field, a number of technical challenges were overcome through a series of new technologies, and their successful development and implementation.
