The objective of this study was to assess the presence and condition of marine growth on floating facility riser systems in the Gulf of Mexico and practices used for inspection, removal and mitigation.
The primary objectives of this project are to (1) consider the full suite of environmental data (meteorological and oceanographic) and structural performance data that could be collected during exploration and production operations off the coast of Alaska, and review each type of measurement in terms of its potential value to the design of future offshore infrastructure; and (2) assess alternatives and develop a recommendation for how MMS should go about collecting, archiving and processing this data.
The project will be accomplished via the following tasks:
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 develop a computer software solution to model the behavior of wet or dry gas from a single-phase sub-sea pipeline release (rupture) from sea-bed to harmless in-air concentration.
Work focused on nine tasks, including:
1. Identification of Typical Gas Pipeline Release Scenarios,
2. Estimation of Gas Pipeline Accident Probabilities,
3. Modification of POSVCM for Gas Release from Sub-sea
Pipeline,
4. 3D Gas Rise Modeling,
5. Graphical User Interface Modifications,
The objective was to study factors affecting soil and pipeline deformation below scouring ice ridges in the Arctic environment. The study provided:
detailed characterization of moving ice-ridge morphology on the basis of available observations and measurement reports,
response simulations of ice-ridge-soil-pipeline systems by means of computational-fluid-dynamics representations and finite-element models that capture flow and deformation in porous media, and
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.
The objective of this study was to provide design options for Pipelines with regard to Arctic hazards such as strudel scour, upheaval buckling, and ice gouging in the Beaufort and Chukchi Seas. Design options included evaluation of PL configuration, material selection, design parameters, operating conditions, application of strain-based and limit state design methods. Design issues included construction, operations, integrity management, maintenance and intervention.
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).
Experience of deepwater Steel Catenary Riser (SCR) applications in the Gulf of Mexico (GOM) has shown that fatigue is usually one of the most challenging feasibility issues for SCR design. Wave loading, VIV, and other environmental and design challenges have also contributed to the fatigue that these riser system are subject to.
The objective of this study was to focus on industry's understanding and incorporation of regulatory requirements regarding deepwater riser design and installation and find practical methods to mitigate gaps.
The Offshore Federal Oil & Gas infrastructure includes over 33, 000 miles of pipeline that provides the means to service and transport approximately 30 percent 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 needs of existing pipeline operations, some of which remain in operation after 40 years of service and beyond their anticipated service life.
