Using Multibeam SONAR Technology Through the Life of Marine Construction...

Mon, 20 Jan 2020 09:07:29 GMT

In marine construction projects, work is often done “in the blind”. Using multibeam SONAR technology can aid this process in all phases of the project. Pre-construction scans can provide a base line look at an area. This can help put real numbers on quantities as well as highlight any anomalies in the project area that may have otherwise gone unnoticed. This additional information increases the accuracy of estimates and the effectiveness of planning. During the construction phase, multibeam SONARs mounted on construction barges can provide real-time progress updates allowing the operator to work with the most up to date information. The SONAR data integrates seamlessly with marine construction machine guidance software to create a total solution package. In the Post-construction phase, multibeam SONARs can be used to create As-Built surfaces of the finished product as well as validate that build specifications were met. This presentation provides recent, real-world examples of multibeam SONAR use during marine construction project phases as described.

The Technological Evolution of Dredging

Wed, 15 Jan 2020 13:10:31 GMT

From its inception in the late 1800's, the hydraulic, or pipeline, dredge has been the dominant machine used for near-shore and in-shore sediment transportation in the United States. These dredges were initially deployed to maintain sufficient channel depths to facilitate river navigation, port access and development. Infrastructure development after World War II created an inland market for sand and gravel mining dredges used in the production of concrete and asphalt. This material dredging market is at least an order of magnitude larger than the navigational dredging market in the US. Other public and consumer concerns, such as environmental remediation and coastal restoration, have created niche dredging strategies and equipment.

Hydraulic dredges have evolved from steam powered, manually controlled devices to sophisticated, energy efficient machines designed to present minimal negative effects on the environment. The equipment being manufactured today incorporates advanced algorithms to predict pipeline lengths, elevations, particle grain size, and required transport velocities. Many of these machines assist the operator in controlling the dredge's navigational path and speed as well as the production rate. In the next several months, several dredges in North America will be deployed with autonomous capabilities that include artificial intelligence and real-time sub-surface imaging and mapping with the primary goal of increased efficiency with less risk.
