The objective of this project is to review the lessons learned from previous applications of Dual Gradient Drilling and to update the current status of technology as it exists today; summarizing with a risk profile and describing the technical maturity of the dual gradient drilling applications.
The objective of this study was to evaluate and extend pipeline risk assessment methodology for deepwater pipelines in areas of uneven seabeds. Study objective included:
Task 1: Evaluation of Data Quality Objectives for Furrow Regions
Task 2: Development of Approximate Method for Analyzing Pipeline Risk in Furrow Regions.
In the offshore and shipping industry, extreme wave events have led to extensive damage and destruction of offshore structures. Hurricanes Ivan, Rita, Katrina, Gustav and Ike that hit the Gulf of Mexico and severe storm events experienced in the North Sea illustrate the importance of extreme wave design for all types of offshore structures. As the U.S. grows increasingly dependent on the steady supply of energy from federal offshore oil and gas reserves, BOEMRE remains attentive to new technologies that safeguard offshore energy facilities, their personnel, and the environment.
This research studied hydrogen damage susceptibility (e.g., cracking and pitting) of steel pipe due to the effect on magnetism in combination with cathodic protection. This recent phase (Phase III) of research built on findings made during Phase I that ended in December 2005 (TAP Study 487) and Phase II that ended in February 2007 (TAP Study 522).
The objective of the project was to study the mechanism by which oil viscosity limits the effectiveness of dispersants. Specifically, two viscosity issues were studied. One was the ability of the dispersant to penetrate into viscous oil upon initial application prior to being washed away by surface water. The other was the internal visco-elasticity of the oil-dispersant mix (in conjunction with the dispersant dosage that has successfully mixed into the oil) that may prevent the oil from being broken into droplets when wave energy is applied.
The objective of this research program was to extend the research on chemical herders into pack ice conditions (mechanical containment recovery), in salt marshes (mechanical recovery and in situ burning), and in open water (dispersants). This project was a direct continuation of TAR Project 554 Mid-Scale Test Tank Research on Using Oil Herding Surfactants to Thicken Oil Slicks in Broken Ice.
