SUBSEA OIL AND GAS PRODUCTION SYSTEMS ARE FINDING INCREASING APPLICATION AS THE DEPTHS AND ENVIRONMENTS FROM WHICH PRODUCTION WILL TAKE PLACE BECOME MORE DEMANDING. SOME OF THESE ENVIRONMENTS, SPECIFICALLY THE ARCTIC, WILL NOT PERMIT UTILIZATION OF CONVENTIONAL UNDERWATER INTERVENTION TECHNIQUES OWING TO THE ICE COVER. TO ASSURE SAFE AND POLLUTION-FREE OPERATION OF THESE STRUCTURES WILL REQUIRE DE ...

THERE IS A NEED FOR DEVELOPMENT OF A COMMERCIALLY AVAILABLE ECONOMICAL ACOUSTIC DOPPLER BACKSCATTER INSTRUMENT WHICH CANBE EASILY DEPLOYED AND USED TO SIMULTANEOUSLY ACQUIRE CURRENT PROFILE DATA AND BACKSCATTER AMPLITUDE INFORMATION RELATING TO PARTICLE CONCENTRATIONS IN THE WATER COLUMN. THE RESEARCH PROPOSED IN PHASE I IS DIRECTED AT TWO AREAS OFDOPPLER BACKSCATTER MEASUREMENT WHERE ADVANCES IN ...

WHEN IT IS NECESSARY TO RAISE A MARINE PIPELINE FOR REPAIR DUE TO TRAWLER SNAG, ETC., THE PIPELINE WILL BUCKLE, AND THEN THE BUCKLE WILL PROPAGATE IF ALL CONDITIONS ARE NOT PROPER. WITH SEVERE BUCKLES, THE PIPE WILL BREAK OPEN ALLOWING THE OIL TO SPILL. THIS CAN BE MINIMIZED BY PERIODICALLY PLACING REMOTELY OPERABLE VALVES IN THE LINE FOR CUTOFF. BUT SOMETIMES THE PIPELINE ROTATES AS IT IS BEING L ...

USING RADIO TELEMETRY MODEMS, IS CURRENTLY POSSIBLE. THIS IS NECESSARY BECAUSE LACK OF MONITORING CAUSES INADEQUATE CONTROL OF INTERNAL CORROSION TAKING PLACE INSIDE OFFSHORE PIPELINE SYSTEMS. THE NET RESULT IS PIPELINE FAILURE DUE TOTHE EFFECTS OF CORROSION. THE RESULT OF PIPELINE FAILURE WILL BE AN OIL SPILL IN COASTAL WATERS. AS THE NATION'S OFFSHORE PIPELINE SYSTEM GROWS OLDER, THE NET EFFECTS ...

THIS PROJECT WILL EXAMINE THE PROCESS OF WAVE EROSION OF FROZEN OR PARTIALLY FROZEN SLOPES. THE SPECIFIC APPLICATION IS THE EROSION OF UNPROTECTED CAUSEWAY BERMS BEING CONSTRUCTED IN THE ARCTIC. THE RATE EROSION, THE NEED FOR SLOPE PROTECTION (OR NON-NEED), AND THE TYPE OF SLOPE PROTECTION REQUIRED WILL BE IDENTIFIED. THE TEST WILL BE CONDUCTED AT PROTOTYPE SCALE TO CORRECTLY MODEL THE THERMAL ERO ...

MULTIPLE LARGE-DIAMETER PILES (SPUDS) CAN BE EFFECTIVE AS PART OF A FOUNDATION SYSTEM FOR GRAVITY STRUCTURES IN THE ARCTIC. THE MAIN PURPOSE OF THE SPUDS IS TO HELP TRANSFER HIGH LATERAL ICE LOADS TO MORE COMPETENT SUBSURFACE SOILS. THERE ARE CURRENTLY NO DESIGN GUIDELINES FOR SPUDS. TEST RESULTS AND DESIGN CRITERIA FOR LONG PILES ARE NOT APPLICABLE BECAUSE THEY DO NOT INVOLVE SIGNIFICANT LATERAL ...

SEAFLOOR DEPOSITS OF COBALT-RICH FERROMANGANESE CRUST WITHIN THE U.S. EXCLUSIVE ECONOMIC ZONE OFFER A POTENTIAL NEW MINERAL RESOURCE FOR STRATEGIC METALS. EVALUATION OF THESE DEPOSITS IS A PRIME OBJECTIVE OF CURRENT AND PLANNED DEPARTMENT OF INTERIOR RESEARCH EFFORTS. PRESENT CRUST SAMPLING DEVICES ARE INADEQUATE FOR EFFICIENT RESOURCE ASSESSMENT. THE DEVELOPMENT OF A TETHERED, MULTI-SAMPLE CORING ...

INTEREST HAS DEVELOPED IN THE REDUCTION OF MINERALS BY A 150KW LABORATORY MODEL OF THE ROTARY PLASMA ARC FURNACE (RPAF) PARTICULARLY FOR CONTINUOUS PREPARATION OF FERROCHROMIUM FROM DOMESTIC CHROMITE FINES. ALL SUPPORT, TO DATE IS IN PROCESS DEVELOPMENT BUT A LARGER IMPROVED PROTOTYPE IS NEEDED FOR IMPROVED FURNACE COMPARISON DATA. THIS IS A DIFFICULT DESIGN PROBLEM BECAUSE OF THE HIGH SENSITIVITY ...

THIS PROPOSAL IS TO MODEL THE TRANSPORT OF POLLUTANTS IN UNSATURATED POROUS MEDIA FLOW. THE MODEL TO BE USED WILL BE A THREE-DIMENSIONAL UNSATURATED-SATURATED FLOW MODEL COUPLED WITH A THREE-DIMENSIONAL CONVECTION-DISPERSION EQUATION. THE MODEL WILL BE IMPLEMENTED ON A CDC CYBER 205 SUPERCOMPUTER WHICH HAS THE SIZE AND SPEED NECESSARY TO MAKETHIS APPROACH A REALITY. PHASE I OF THE PROJECT WILL BE ...

QUANTITATIVE GEOMORPHIC GUIDELINES ARE LACKING FOR THE DESIGN AND CONSTRUCTION OF RECLAIMED SURFACE MINE TOPOGRAPHY. STABLE TOPOGRAPHY IS NECESSARY FOR RECLAIMED AREAS IN ORDER TO REDUCE SEDIMENT POLLUTION TO OFFSITE AREAS, TO ALLOW RAPID DEVELOPMENT OF VEGETATION, AND TO MEET STATE AND FEDERAL LAWS. GUIDELINES FOR GEOMORPHIC DESIGN OF STREAM CHANNEL NETWORKS WILL BE DEVELOPED FROM ANALYSIS OF NAT ...
