The objectives of the JIP is to expedite the publication of the updated ISO 13628-12 and update of API RP2RD, working in conjunction with the existing joint ISO/API Task Group and Chairman.
The objective of this study was to: Extend the database of wave statistics,
Capture storm and loop current events and analyze TLP response to these events,
Assess occurrence of riser and tendon VIV events.
This study served to provide a two-year extension of work initiated under TAR Study 564 and included:
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.
The objective of this project is to evaluate the state of practice in fatigue assessment in the offshore industry today. Of interest is an understanding of how fatigue life calculations are undertaken and how both load and resistance side uncertainties are employed in design for fatigue.
This objective will be accomplished via the following tasks:
The primary objective of this project is to investigate the static and dynamic stability of various classes of TLPs under extreme hurricane and loop current conditions where one or more tendons have been lost due to damage or disconnect.
This objective will be accomplished via the following tasks:
The objective of this project is to develop a better understanding of the performance of the casing-cement bond under HPHT well conditions leading to a model to predict well life.
Project Goals:
Description of the importance of cement fatigue to the life of HPHT wells
Lab procedures and prototype test cell to measure the performance of cement in cyclic loading under HPHT conditions
Model to predict life of HPHT wells
Recommendation for further work
The Scope of Work for this effort will be divided into five (5) sub-projects: (i) Managing Hydrates in Late Field Life Situations; (ii) Under-inhibited Systems; (iii) High Pressure Jumper Design; (iv) Development of Techniques to Monitor Hydrates and/or Characterize Hydrate Slurries; (v) Development of Simulation Tools. The tasks are described as follows: Managing Hydrates in Late Field Life Situations Simulate several late field scenarios with focus on high water cut, emulsified oil, and low gas-oil-ratios.
The objective of this study was to develop design review recommendations for the connection hardware used for TLPs and similar structures such as mini-TLPs at the tops and bottoms of the tendons.
This project investigated the accuracy of non-invasive deepwater subsea inspections performed by common ROV-supported inspection tools and provided a comprehensive assessment of the knowledge gained from recent work on subrope behavior.
The objectives were:
This project is a material testing program to enable operators to safely produce oil and gas from high-pressure high-temperature (HPHT) and sour HPHT reservoirs. Completion of the testing program will support more widespread development of HPHT and sour HPHT reserves by providing designers with some of the material property data necessary to perform design verification analyses in accordance with American Petroleum Institute Recommended Practice 6HP (API RP 6HP).
