This project evaluated the force-displacement response of buried pipelines under saturated sand and clay conditions under lateral loading. This research was full scale. A review of accepted methods of offshore pipeline/soil interaction analysis, especially pertaining to mudslides and earthquake-related hazards was conducted.
The workshop is designed to define the state of the art of corrosion protection of marine structures and pipelines, to define the state of the art of testing for corrosion damage, to identify the technical and non-technical barriers which hinders a fuller utilization of advanced methods for mitigating corrosion on marine structures and pipelines, and to identify research and development projects that would advanced corrosion mitigation technologies. Marine structure is defined as offshore structures, harbor structures and ship structures.
This JIP was formed to investigate the recent increase in early vibration fatigue failures to welded connections in thin-walled piping on offshore installations. The project included data collection, fatigue testing, and formulation of design guidelines. Current design procedures for offshore piping considered static stress levels, and sometimes, low frequency resonance modes. New materials used in piping made these design criteria obsolete. Increasingly, thin walled piping, made of new materials such as duplex* or stainless steels, was being installed offshore.
TUFFP is a JIP with an industry consortium of 17 member organizations that conduct fluid flow research to maximize flow and analyze problems such as corrosion and erosion.

This is a Cooperative Agreement. A workshop will be held as part of the Joint Symposium of the 13th International Okhotsk Sea and Sea Ice Symposium and Ice Scour and Arctic Marine Pipelines Workshop in Mombetsu, Hokkaido, Japan. The workshop will be held from February 1-5, 1998.
This is a cooperative agreement. To organize, conduct, and document results from an international workshop on Pipelines Safety Assessment and Risk Management Methods. The workshop will bring together pipeline operators, contractors, inspectors, engineers, managers, analysts, researchers, and regulatory agency personnel from around the world to define discuss, and identify the strengths and weaknesses of the various methods and approaches that have been and are being developed for pipeline safety assessment and risk management.
This is a continuation of the Pressure Ridge Ice Scour Experiment (PRISE), Project 191. The objective of this project is to confirm the magnitude and extent of sub-scour deformations in dilatant soil, through:
1) direct field observations;
2) physical model simulations;
3) numerical model simulations; and
4) development of an indigenous knowledge workshop.
The object of this project was to research current methods involving mathematical analysis of pipeline spans resulting from various configurations, i.e., bottom profiles, pipeline crossings, outcrop pinnacles, etc. Results of the analysis were compared with results from modern finite elements analysis (FEA) programs. The effects of thermal expansion, residual lay stresses and on-bottom stability will also be included in the analysis. The project encompassed the design process related to span analysis.
This is a Joint Industry Project (JIP) on the reliability of corroded pipelines. This project sought to develop reliability methods for the assessment of pipeline corrosion, considering the uncertainties of inspections and estimation of burst strength and corrosion-rate. This project was designed for the development of pipeline design rules and pipeline operation and maintenance.
The purpose of this project was to develop the Banff/97 Workshop, which was held in Banff Canada. This was the fourth in a series of workshops that Natural Resources Canada (NRC) organized to address new pipeline technology. The workshop reviewed the progress achieved since the 1995 workshop and carried out intensive group discussions on such topics as risk assessment/risk management, stress-corrosion cracking, operations and maintenance, abandonment issues, and in-line inspections.
