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...
Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...
A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...
Appraisal of Lightweight Moorings for Deep Water
This paper outlines the potential advantages of using lightweight fiber ropes for mooring floating production platforms. The influence of tether properties on mooring system response is discussed. It is...
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...
Introduction
The purpose of this white paper is to: foster understanding and transparency of analytical methods necessary to update and describe climate, including possible changes in the frequency...
Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...
Incorporating Climate Science into Engineering Practice
This section provides a review of engineering practices and discusses how engineers canconsider climate change in their practice, given the uncertainty of the future....
Civil Engineering Sectors
This section reviews the challenges for engineering practice posed by climate variability for the following traditional infrastructure sectors and special themes....
Research, Development, and Demonstration Needs
Research, development and demonstration (RDD) is needed to advance recommended civil engineering practices and standards in order to effectively address climate change impacts. Wilbanks...
Summary, Conclusions, and Recommendations
Civil engineers have responsibilities for the planning, design, construction, operation and maintenance of physical infrastructures. These infrastructures include all types of buildings,...
Introduction
Many institutions and private industry organizations have prepared guidance documents with the latest scientific and engineering information on proper design, installation, maintenance,...
Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...
Porous Asphalt and Permeable Friction Course Overlays
Porous asphalt typically consists of conventional warm mix asphalt (WMA) or hot mix asphalt (HMA) with significantly reduced fines resulting in an open-graded mixture that allows water...
Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....
Permeable Interlocking Concrete Pavement (PICP)
Permeable interlocking concrete pavement (PICP) consists of (impervious) manufactured concrete units that form permeable voids and joints, when assembled into a laying pattern. The openings...
Grid Pavement
Open grid pavements consist of concrete or plastic units with large surface openings filled with a permeable joint material, typically small aggregate (ASTM No. 8 or No. 89), sand, or...
Alternative Technologies
In recent years, new permeable pavement product variations have entered the market. This chapter describes general characteristics for several emerging products. The following types of...
Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...
Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...
