Safe operation of the current Navy lighterage system can be performed in Sea State 3 and below. At present, sea state estimation is made by Navy personnel and is dependent on their level of experience.Creare is developing an automated Sea State Predictor (SSP) to provide a more accurate and reliable determination of the current sea state. The system relies on measurement of heave of the warping tu ...

To address the need for oceanography tactics training able to enhance community knowledge of how oceanography impacts antisubmarine-warfare (ASW) prosecution in both analysis and employment of tactical sonar systems, ARiA will build on the success of the Phase I effort to further develop the ESAIL Cloud software-based tool for generation of training content on tactical employment of oceanography t ...

Within the increasingly contested undersea operational arena, the Navy needs a tactical and competitive advantage in undersea sensing and detection through improved situational awareness with respect to environmental parameters, such as sound speed profile (SSP) and bottom properties, that affect overall submarine sonar sensor performance. Current approaches for enhancing environmental situational ...

Agricultural row crops occupy over 240 million acres of land in the United States (USDA-NASS2012). Decisions regarding the implementation of management practices in these agricultural areashave a significant effect on other environmental outcomes including soil erosion water quality andcarbon sequestration. There is currently no systematic and cost-effective method for documentingdetailed informat ...

Cross Deck Pendants (CDP) used to recover aircraft onboard aircraft carriers are exposed to a challenging environment of physical impact, abrasion, and strain which limit life expectancy to approximately 125 arrestment cycles. Three primary effects are known to contribute to CDP failure including tail hook impact, hook slip, and final bending around the hook, although the precise contributions of ...

To address the Navy need for enhanced ambient-noise modeling for sonar-sensor performance estimation, sonar tactical decision aids (TDAs), and simulation-based training, ARiA will develop, demonstrate, and transition key building blocks for an enhanced multidimensional ambient-noise model (MDANM) needed to overcome the limitations of the current state of practice for noise modeling in sonar TDAs a ...

Accidentally released lubricant into water bodies from hydropower production turbines and other marine (cruises, ships) applications challenges safe water recycling and management, and has invited a number of lawsuits.According to the Environmental Protection Agency, up to 16 million gallons of lubricants per year ? equating to 1.5 times the size of the Exxon Valdez spill ? are washed off into wat ...

Every year, the global wind industry loses an estimated $100M or more to damage caused by lightning.A new blade coating will reduce the damage to wind turbine blades caused by lightning by promoting the formation of ionization channels over the surface of the turbine blades, providing a safe external path for lightning energy to reach ground and preventing damaging blade punctures.The coating cons ...

Welded stainless steel canisters that contain spent nuclear fuel (SNF) at near-marine sites have been found with salts on their outer surface that could lead to pitting, stress corrosion cracking (SCC), and potential release of radioactive materials.Welds that are most susceptible to SCC are difficult to reach because canisters are installed in concrete over-pack structures with limited access.Mit ...

With development of shale gas fracking, large amounts of methane and ethane have now become available at low cost. With this low cost ethane it is desirable to convert low cost ethane to high value ethylene. Oxidative dehydrogenation (ODH) for low cost conversion of ethane to ethylene is a potentially attractive route. ODH is an exothermic process for converting ethane to ethylene. By contrast pro ...
