Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Extreme Wave-Force Calculation Procedure for 20th Edition of API RP-2A
The paper describes the revised guideline design wave force calculation procedure approved for the 20th edition of the API-RP2A WSD and the first edition of the API-RP2A LRFD and contrasts...
A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...
The Hail Problem
Unlike some other forms of precipitation, hail comes in bursts of short duration, falls over isolated and unpredictable locations, and usually occupies only a small percentage of the total...
The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...
Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...
Axial Load Capacity of Pipe Piles in Sands
The axial load capacity of driven, open-ended, steel pipe piles in cohesionless soils, is often estimated using a method such as the American Petroleum Institute Recommended Practice 2A...
Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...
Performance of Suction Caissons in Sand and Clay
The use of suction caissons (suction piles) in marine environments has been increasing in the last decade. A suction caisson is a steel pipe with an open bottom and a closed top that is...
Pile-Driving Formulas for Friction Piles in Sand
Dynamic pile-driving formulas are widely used in predicting the load-carrying capacity of friction piles and in writing pile-driving specifications. Further, when load tests are available,...
Axial Capacity of Steel Pipe Piles in Clay
Development of theories for the prediction of the axial compressive and tensile load capacities of driven piles is made difficult by a variety of factors, e.g., disturbance of the soil...
Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...
Case Study of Offshore Pile System Reliability
This paper presents the results of research effort to evaluate the reliability of offshore pile foundation systems. It is an extension of previous work by the authors [14] dealing with...
Sustainable Development � A Geotechnical Perspective
Sustainability has become a key factor in major construction projects these days, and many geotechnical engineers have started focusing on the concept. Owners, public agencies, and the...
Reliability and Resilience � Essential Ingredients of Sustainable Geotechnics
Sustainability of a system is its ability to survive and retain its functionality over time. In very simple terms, sustainability deals with the capacities (resistances) and demands (loads)...
Enhanced Detection and Mapping of Buried Utilities�A Sustainability Perspective
The social and environmental impacts and benefits of projects make up the triple bottom line that represents a modern view of sustainable project development. Rather than considering only...
Asset Management of Earth Retaining Structures: Design through Design Life
Regarding new earth retaining structures (ERS) construction, the message is clear: plan for asset management. New construction is certainly not immune to performance issues, and the time...
The Transbay Transit Center: Breaking New Ground in Urban Geotechnics
A building boom centered around the construction of the new Transbay Transit Center (TTC) is transforming the South of Market neighborhood in downtown San Francisco, newly dubbed the Transbay...
Design-Build and Public-Private Partnerships: Risk Allocation of Subsurface Conditions
Project Owners, especially in the public sector, are exploring and utilizing alternative project delivery methods, such as design-build (D-B) and public-private partnerships (P3s). Some...
2012 Geo-Wall Competition
Highlights from the Geo-Wall Competition at the 2012 Geo-Congress. Teams from 17 universities competed to construct a model mechanically stabilized earth (MSE) retaining wall out of craft...
