At the Reliance project site in Vijayawada, a subgrade stabilization solution was deployed to address weak soils in a flood-prone tropical climate. Ocean Biaxial Geogrid 30 kN, supplied by Ocean Non Wovens, was selected and installed over 1,950 SQM to distribute loads and reinforce the subgrade for long-term performance. ...
Stability of slopes and embankments remains a persistent challenge in civil engineering, particularly where seasonal rainfall, soil erosion, and uneven terrain impact infrastructure integrity. In Shajapur, Madhya Pradesh, an infrastructure stabilization project deployed Ocean Gabion Boxes as a mechanically stable, permeable retaining system designed to adapt to ...
Synopsis: Systems that dilute wastewater before depositing it into the ocean will deposit concentrated wastewater when they fail – violating environmental regulations. Application: The MarineFAST® treats, rather than dilutes, wastewater, and operates without needing to release wastewater into the ...
Exposure and risk present themselves in many ways, through the process of engineering design--from rogue ocean waves and avalanches, to blistering summer heat and long, cold winters. ...
Spotter’s barometer provides excellent accuracy (+ / - 1 mbar, 0°C to 50°C) and has been rigorously tested at sea by our ocean science and engineering teams. Surface pressure variations are an important proxy for weather changes and, as a result, Spotter’s barometer unlocks many new use cases. ...
The study of artificial intelligence began in 1956 when the term ‘Artificial Intelligence’, (AI) was first used at a meeting held in Dartmouth College in Hanover, New Hampshire, United States. Artificial Intelligence and Machine Learning, a broad discipline, was developed based on the collaboration of several kinds of fields such as cybernetics, computer science, information theory, ...
In reaction to recent worldwide occurrences of terrorism and war, the US military has heightened its security activities by several orders of magnitude. Unlike earlier conflicts, these new threats are acknowledged to be global in nature and require global responses. For economic, political, and practical reasons (not to mention human safety), it is impossible to adequately respond to these ...
Objective The Carillon power station is a run-of-river power station. The waste material grapple fell upstream from unit 4 after the breaking of its steel wire rope. The use of the ROV allowed work in simple access mode to the installation with a short time of set-up. Only 2 units were stopped instead of 5 with the divers method. Stoppage of more than 2 units at this particular time would have ...
GE Nuclear Energy (GENE) has developed a variety of specialized inspection tools and techniques for the services they provide to nuclear power plant operators in the US and around the world. The Nuclear Regulatory Commission requires many areas inside boiling water reactors, such as welds and pipes, whose structural integrity need to be inspected during refueling outages. The economics of taking ...
ABSTRACT The challenges of homeland security require a suite of underwater tools and sensors. This paper will focus on the underwater role of the Remotely Operated Vehicle (ROV), and its pros and cons for this mission. Interviews and demonstrations with military personnel indicate that a balance of power, payload, portability, versatility and ease of operation is needed for ship hull and port ...
Objective During the construction of the Péribonka hydropower plant, a bathymetric survey was conducted using the Maski inspection class ROV after the blasting of the spillway to ensure that all the debris were recovered. The ROV was also utilized to map and geo-reference the submerged area for future inspection ...
