Decommissioning Methodology and Cost Evaluation for Alaska OCS Region Offshore Oil and Gas Gravel Island Facilities

The objective of the study is to provide the Alaska OCS Region with research and cost estimating regarding decommissioning of a typical arctic gravel island-based, oil and gas exploration/production facility. The work considered standard industry practice, available technology, current regulations (e.g. 30 CFR 250 Subpart Q) and market conditions.

Remote Visual Inspection Joint Industry Project

The United Kingdom, Health and Safety Executive (HSE) is conducting research in a Joint Industry Project (JIP) aimed at providing a stronger understanding of both the benefits and limitations of RVIs and develop a set of best practices when conducting these types of inspections. The JIP will:

  1. Assess current technologies and practices
  2. Conduct RVI trials for probability and detection
  3. Determine the human factors and competence assessment
  4. Develop a good practice guide and methodology for demonstrating competence for RVI 

Status of Arctic Pipeline Standards and Technology

Provide the BSEE Alaska Region with a comprehensive review and gap analysis of current United States (U.S.), State of Alaska and
international regulations, standards, and related specifications and technical reports for offshore hydrocarbon carrying pipelines in
Arctic conditions incorporating the new Federal Arctic Rule and including, but not limited to, American Petroleum Institute (API)
documents. Report on the state of the art and emerging technology of offshore hydrocarbon carrying pipelines in Arctic conditions

Determination of Fracture/Fatigue-Fracture Behavior of Equipment Constructed with Cladded Weld Materials

This project will define a general approach to, and advance development of, a useful predictive computer-modeling tool for analyzing failure modes of cladded materials used in oil and gas operations. It will develop and validate a constitutive model to define fatigue and fracture behavior of cladded pipe under deep-water conditions. The failure prediction tool will predict fatigue and fracture performance of cladded weld materials in equipment used in high pressure (15 ksi) and high temperature (>350℉) (HPHT), corrosive environment (H2S, Cl, S and CO2).

TAP-695-Slug Loading and Response in Pipeline (SLARP) JIP

The overall description of the proposed research is to investigate and conclude current state of industry practice and technology gaps with respect to evaluating slugging effects on pipeline, spools and riser, to investigate alternative methodologies analysis methods for defining slug and turbulence loading and assessing structural response in pipeline and spool and riser, to develop best practices guideline for modeling and analysis of slug and turbulence loading and response of pipeline, spool and risers.

TAP-664-Safebuck Phase III and Safebuck Geo JIPs

Increase knowledge, and thereby reduce conservatisms, associated with the design process and related limit states of deepwater pipeline design. The key areas of work are: Undertake structural reliability analysis (SRA) to confirm that the SAFEBUCK Design Guideline methodology ensures that the pipeline failure probabilities are consistent with industry targets;
Collection of data on operating pipelines to generate lessons for future design by sharing the combined knowledge of lessons learned from recent projects;

TAP-642-Assessment of Damage and Failure Mechanisms for Offshore Structures and Pipelines in Hurricanes Gustav and Ike

The objectives of this research was to catalogue for archival purposes details about platform and pipeline damage and destruction caused by hurricanes Gustav and Ike. The work will also evaluated technically what went right and what went wrong in order to identify issues that can be changed in design codes so these problems do not occur again on new structures (platforms and pipelines) or to identify issues with existing structures that can be remedied prior to future hurricanes.

TAP-623-Evaluation of High Integrity Pressure Protection System (HIPPS)

The objective of this study was to provide guidance for a testing framework that would not compromise the reliability and safety of future HIPPS installations in the Gulf of Mexico. The study provided guidance on the allowable (if any) leakage rates and developed recommendations on HIPPS test configurations that would mitigate concerns over practical limitations to testing.
