General
Design of Latticed Steel Transmission Structures specifies requirements for the design, fabrication, and testing of members and connections for electrical transmission structures. These...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

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...

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...

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...

Shear and Interface Strength of Clay at Very Low Effective Stress
Thin-specimen direct shear (TSDS) tests were conducted to measure the shearing strength of kaolinite, and interface strengths between kaolinite and acrylic plastic and anodized aluminum,...

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...

Advanced Fracture Control Procedures for Deepwater Platforms and Compliant Towers
This paper describes an integrated approach to fracture control problems – applied first as a necessary adjunct to the authors' own engineering practice, then in developing...

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...

Design and Installation of Auger Steel Catenary Risers
The Auger export pipelines are connected to the TLP by steel catenary risers (SCRs). This is believed to be the first time steel pipe has been used for catenary risers. SCRs offer advantages...
