TAP-645-The Performance of Drag Embedment Anchors

Reliable deepwater anchor performance is critical for mooring floating Mobile Offshore Drilling Units (MODUs). Anchor failure can result in MODUs going adrift and colliding with other topside structures as well as dragging anchors that can damage subsea pipelines, seafloor production systems and natural sealife communities.

TAP-578-Assessment of Fixed Offshore Platform Performance in Hurricanes Katrina and Rita

The objective of this effort was to conduct a qualitative and quantitative assessment of fixed offshore platforms that were affected by Hurricane Katrina and/or Rita. Resulting data was evaluated to determine if any common trends occurred, and also to determine if current API standards are an accurate indicator of expected performance. Coordination and consultation with the API HEAT group occurred throughout the project.

TAP-579-Joint Industry Project to Study Risk-Based Restarts of Untreated Subsea Oil and Gas Flowlines in the GOMR

This project assesses potential solutions to the disruptions of production restart from hydrates affecting pipelines after a long shut in period such as a hurricane. Work shows that it may be possible to reduce the risk of hydrate plugging by selecting an appropriate restart rate. MMS and industry will use the results of this project to reduce the risk of having hydrates stop production restarts.

TAP-580-Hindcast Data on Winds, Waves and Currents in Northern Gulf of Mexico in Hurricanes Katrina and Rita (2005)

The objective of the study is to develop a database of wind, sea state and currents resulting from Hurricanes Katrina and Rita meteorological data and application of advanced hindcast models. Oceanweather Inc. (OWI) responded to urgent industry needs for a preliminary assessment of the impact of Hurricanes Katrina and Rita by performing and distributing to several offshore operators an emergency response (ER) wind and wave hindcast.

TAP-581-Pipeline Damage Assessment from Hurricane Katrina/Rita

The Offshore Federal Oil & Gas infrastructure includes over 33, 000 miles of pipeline that provides the means to service and transport approximately 30% of our nation's domestically produced oil and gas from offshore wells to onshore refineries. As the U.S. grows increasingly dependent on the steady supply of energy from offshore oil and gas reserves, MMS remains attentive to the destructive forces of hurricanes and the extensive challenges to protect pipelines in advance of and to re-start pipeline production following these catastrophic natural events.

TAP-591-Evaluate Accuracy of Polyester Subrope Damage Detection Performed by ROVs Following Hurricanes and Other Events

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:

TAP-593-Evaluate and assess the performance of jackup rigs that were subject to Hurricanes Katrina or Rita

In August and September 2005 Hurricanes KATRINA and RITA came through two of the main exploration and production areas of the Gulf of Mexico. These hurricanes permanently removed five jackups from service, with damage sustained to another 13+. A total of 23 jackups are said to have sustained minor to extensive damage. Early reports indicated 19 MODUS became adrift (both jackups and semi-submersibles). Several of those were swept away and floated through the important oil and gas infrastructure of the GOM prior to grounding or being taken under tow.

TAP-599-Tulsa University Hydrate Flow Projects (TUHFP)

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.

TAP-603-Stability of Tension Leg Platforms with Damaged Tendons

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:
