Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

Heave Compensated Landing System - A Novel Tool for Subsea Intervention
This paper presents a new intervention system that allows the use of a low cost workboat to deploy and recover delicate payloads in subsea installations. Vessel motions are decoupled from the subsea package...

Guidelines for Construction Vibrations: How Much Rattle is Too Much?
The study of construction/blast-related ground vibrations on structures, people, and objects is a surprisingly diverse field. Vibration sources vary from blasting, all types of construction equipment,...

A History of Deep Vibratory Methods for Ground Improvement: A Cost-Effective Foundation Solution for 80+ Years
Deep vibratory ground improvement methods, collectively referred to as vibro systems, have been utilized by the construction community in one form or another for the past 80 years. Development of the equipment,...

Post-Earthquake Reconnaissance Using Digital Imagery: A Bird's-Eye View
Over the last decade, remote sensing has played an increasing role in geotechnical earthquake reconnaissance through the use of satellite imagery, LIDAR, and unmanned aerial vehicles (UAVs). These techniques...

You Designed It for the Big One, Right? Illustrating and Communicating Uncertainty in a Deterministic Seismic Hazard Analysis
In seismic regions of the U.S. and worldwide, engineers design structures to withstand seismic ground motions resulting from a large, rare earthquake. But definitions of "large" and "rare" depend on who...

Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...

Instrumentation and Monitoring
A detailed plan for monitoring possible ground surface movements caused by the microtunneling operations should be prepared. The plan is typically prepared by the engineer in consultation...

Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...

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,...

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...
