OTEC Sea Water Systems Technology Status
A workshop was conducted in April 1988 to provide an expert critique of the fabrication and deployment options for the seawater systems (all piping required to draw the seawater) of land-based...
OTEC Seawater Pipe Cost Comparisons
Describes a material which can substantially reduce the cost of seawater pipes and two methods for building and deploying such pipes for use in land-based OTEC installations, outfall sewers,...
Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...
Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...
De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...
Numerical Model for Tsunami Run-Up
Originally published in: Journal of the Waterways, Harbors and Coastal Engineering Division, ASCE, WW3, August 1970, pp. 701-719...
A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Sensitivity Study of the Cyclic Axial Capacity of a Single Pile
Evaluation of the axial capacity of an offshore pile subjected to a severe North Sea storm is presented. Effects of using different degradation criteria, upper and lower bound interaction...
Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...
The South Carolina Coast II. Development and Beach Management
The variety of development and conservation areas is superimposed on a wide range of erosion and accretion histories. Lack of construction setbacks has contributed to the general but probably...
A Review of the South Carolina Method for Establishing Coastal Setback Lines
The location of the setback line will depend to a large extent on the nature of the shoreline. Those areas adjacent to an unstabilized tidal inlet and affected by coastal processes at...
The Coastal Management Program in Brazil
As a proposal to guide the rational utilization of coastal resources, the Brazilian government established the National Coastal Zone Management Plan (PNGC), according to the Federal Law...
Input Management: A Proposal for the Largest Coastal Lagoon in Brazil
Principles of General System Theory and Energy Analysis are used to study the best management technique al Lagoa dos Patos (in southern Brazil), including its watershed and contiguous...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
The Coastline Between Rio De Janeiro and Cabo Frio
The coastline between Rio de Janeiro and Cabo Frio is characterized by successive long beach arcs, oriented in the East-West direction. The beaches are separated by rocky headlands resulting...
Sulfated Polysaccharides from Marine Invertebrates
The authors Laboratory is involved in the chemical and structural determination of sulfated polysaccharides from different sources. The main purpose of such studies is to compare these...
Modelling of Sand Bars in Coastal Environments
A mathematical model describes the formation of sand bars by progressive wind-generated waves. The model decomposes into several constituents linked together in a two step morphological...
Implications of Deep Ocean Modelling on Coastal Sedimentation Prediction
The Harvard University Ocean Predictive Descriptive System is reviewed and recent results of mesoscale ocean prediction are presented for the Northeast Pacific and Gulf Stream Ring Stream...
Suspended Sediment Regression Model on Mud Coasts
Two statistical models of the concentration of suspended sediment on mud coasts have been developed by using the stepwise regression method. The statistical analysis in this paper is based...
Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
