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.

Teledyne RESON SeaBat T-Series Multibeam Sonars and Turbidity in Real-Time...

Fri, 10 Jan 2020 15:14:10 GMT

During most dredging operations, survey verification of having met grade and other contract requirements comes after the dredge has completed its work in a designated work area and hence moved on. What if the post-dredge survey reveals that the dredge has not fully met contract obligations? When this happens, the additional time, effort and expense to get the dredge back into position to remove what was missed can undermine the success of a project. What if the dredge operator could have “eyes under water” and confirm that grade requirements have been met before moving on?

During dredging operations, the material on the bottom is disturbed and released into the water column. Turbidity is a measure of the presence of suspended particulates. The more suspended solids in the water column, the higher the turbidity. High turbidity can create issues for sonar performance in that the suspended solids act as an acoustic reflector.
As barge mounted sonars are being used in the marine construction industry more frequently, dredge operators are considering the use of sonar to provide information in advance of post-dredge surveys. The “As-Building” benefits can be substantial but there is a concern over the effect turbidity can have on the acoustics.

Utilizing the Teledyne RESON SeaBat T-Series advanced bottom tracking abilities in various dredging operations, with varied levels of turbidity, we have begun to both demonstrate the value and quantify the limits of sonar usage during dredging operations. This presentation presents our results thus far.

IDH T-50, BV5000, and LiDAR Mobilization on a Fast Response USV for Canal...

Fri, 08 Feb 2019 09:25:32 GMT

The California Aqueduct is the principal water-conveyance structure of the California State Water Project. From the Sacramento River delta east of San Francisco, it runs south 444 miles (715 km) and is the world’s largest water-conveyance system. Channel sizes vary along the aqueduct, varying from 40 feet (12 meters) to 150 feet (45m) wide at the base, with 30 feet (9 meters) average depth of flow. Additionally, with its unique mixture of over chutes, under chutes, and utility crossings, it has a height clearance limit of 24 inches (0.60cm). Constructed starting in 1960, there are concerns that fluctuating land-surface elevations due to subsidence and uplift in the valley could cause serious operational-maintenance and design construction problems for the California Aqueduct surface-water delivery system. As a result, the California Department of Water Resources has undertaken this study to develop a greater understanding of the location, extent, and magnitude of subsidence along the California Aqueduct, as well as to help understand the relationship of groundwater levels and land subsidence. Since 2005, there have been three unsuccessful attempts to field test a vehicle capable of transiting the canal system with minimal need to recover the vehicle, while having the ability to carry high-resolution multibeam and LiDAR sensors. In December of 2017, Seafloor proposed the development of a 15 foot (4.5m) catamaran vehicle, capable of 8 hours endurance, less than 60cm in overall height, and capable of carrying an IDH T-50 multibeam and high resolution LiDAR sensor. This presentation will produce the results of that program.

Current and future applications of acoustic scanning in marine engineering...

Tue, 15 Jan 2019 08:29:01 GMT

The study highlights the advantages of using acoustic scanning in the survey of key walls, piles, defensive and other civil marine engineering structures, addresses existing and potential problems with this method and suggests a direction for future improvement. It is based on the summary of 25-year experience of marine engineering surveys by GT Corporation SE (Estonia) and its partners, with 10-year experience in acoustic scanning. The key distinction of mentioned application is in very rigorous quality requirements for engineering surveys, very small size (0.5-2cm) of details required, as well as technical problems of scanning vertical structures with high reflective capabilities due to high inclusion of metal components. An additional difficulty are the weather conditions and water qualities specific to the Baltic Sea. To solve this task, the company and its partners use multiple Teledyne products, including PDS software, Seabat T20, Seabat T50, Blueview scanners, all of which will be mentioned during the report with examples of use. Based on the multiple use cases, potential future applications, and expanding engineering survey market it can be seen that a specialized new scanner product type specifically designed for engineering surveys can be used to provide even more informative and higher quality data to potential customers.

Teledyne Multibeam and Dredge Guidance Hardware and Software for Use in...

Sat, 06 Jan 2018 12:07:33 GMT

Abstract:

A $4 Billion project in Tarrytown, New York to replace and demolish the Tappan Zee Bridge is utilizing many aspects of the Teledyne Dredge Guidance portfolio. Five excavators outfitted with Teledyne dredging software (PDS) will be using hydraulic jack hammers to demolish underwater concrete bridge structures. The software allows them to visualize the location of their hammers relative to the structures as well as which portions have already been demolished. A clamshell wire crane outfitted with Teledyne PDS software as well as Teledyne Crane sensors will be used to clean out the debris once the excavators have broken the structures down. Finally, a small survey vessel outfitted with Teledyne PDS Multibeam software and a Teledyne BlueView SONAR provides real time “As-Building" information to the excavators and wire crane so that they have the most up to date information about the structures and debris. With the information from the SONAR, the machines can be sure that an area is fully demolished and removed before moving onto the next one. This will save time and the extra cost of having to go back to a location if something was missed.

Perspectives on the State of Ocean Science

Tue, 14 Nov 2017 09:51:10 GMT

Keynote presentation by Margaret Leinen

The value and role of ocean science and innovation increasingly has been the focus of both international and domestic forums on climate science, sustainability, and defense. Now in its second century of exploration and research, UC San Diego's Scripps Institution of Oceanography is rising to meet new challenges to understand and protect the planet, through interdisciplinary and cross-sector collaborations and a continued focus on developing innovative technology to observe the planet.

Scripps shares its science at international forums such as the United Nations ocean and climate conferences to advise, contextualize and strengthen the efforts of nations, NGO's and policymakers that set and meet standards for sustainable use of the oceans. The United States Navy is also in the midst of assessing the global state of ocean science and technology via Task Force Ocean, and has engaged US academic institutions including Scripps to ensure cutting-edge ocean science is applied to its oceanographic infrastructure, technologies, and technical workforce so that the Navy maintains its global competitive advantage.

In her keynote, Dr. Margaret Leinen will describe these international forums, Scripps role, how Scripps scientists are innovating to meet these global demands in ocean science and technology, and the state-of-the-art research facilities, centers, and education that will shape the future of ocean and climate science.

The Next Great Odyssey of Human Endeavour Exploring the Deep Ocean

Thu, 09 Nov 2017 14:55:25 GMT

Keynote presentation by Oliver Steeds

Humankind is poised to make the next giant leap – into the deep ocean. We now have the technology available to us to discover more of our planet in the next 10 years than we have in the last 100,000.
Throughout human history, exploration has always driven our progress. Lief Ericson's journey to North America (1001 AD), the discovery of the New World (1490s), Magellan's first circumnavigation (1519) and space exploration (1957-) have all pushed back the frontiers of our knowledge, unlocking immense opportunity and changing our relationship to our planet and ourselves.
But since 1969, we've been looking up when we should have been looking down. The most important part of our planet, the deep ocean, remains the least known part of our planet.
The ocean is the heart of our planet. It's 99% of the planet's biosphere[1], regulates our atmosphere and climate and produces 50% of the oxygen we breath[2]. It captures heat and carbon dioxide which dramatically reduces global warming and provides a primary source of protein for 3 billion people[3]. The ocean is everybody's business. How it changes affects us all. The problem is that we don't know how the deep ocean functions, how healthy it is, how resilient it is and how the development of a sustainable blue economy can drive our growth.
The ocean remains the last great unknown frontier on our planet. We've only biologically sampled 0.0001%[4] and mapped an area equivalent the size of Tasmania to the same kind of detail that we have mapped the entire orbs of the Moon and Mars[5].
From Autonomous Underwater Vehicles (AUVs) to Remotely Operated Vehicles (ROVs), from seabed mapping systems and chemical sensors to the initial library of DNA sequences of marine animals, technological developments now unlock extraordinary new research capabilities. We now have the ability to discover more of our planet in the next 10 years than the last 100,000 of human history.
New areas of economic activity such as renewable energy and marine mining are on the horizon. Millions of new species are to be discovered that can propel human medicine. Resources to be unearthed that will drive our sustainable economic development. Even the origins of life on Planet Earth are to be found.
To engage the world in our all of our work, we should be looking to the space community to learn how to improve our story-telling – engaging our audiences with stories that are positive, forward looking and about a brighter future; that are Mission based and trigger the imagination, communicating danger and building on narratives of exceptionalism, patriotism, exploration and the collective human achievement.
Together, as an industry, we are already leading the exploration of the deep ocean, the last, great unknown frontier on Planet Earth.
The Apollo Missions, polar exploration, Jacques Cousteau's adventures, even Felix Baumgartner's space jump captivated the world with their human drama, battles against adversity, and above all, the unknown. We need the unknown. It is the sense of mystery that gives us imagination and makes us human. Our work is the next positive epic story of human endeavor that can inspire humanity.

Applications of Sonar Software Tools for Security and Defense: Mosaicking for Hull Inspection, Non‐GPS Navigation, and a Low‐Cost Bathymetry Tool.

By: Arjuna Balasuriya, Charles River Analytics

Teledyne marine sensors provide data that is valuable for many defense and security missions, from navigation to mine countermeasures to maintenance. In this talk, we will highlight work that uses a variety of Teledyne sensors, including multibeam imaging sonars, multibeam profilers, and Doppler velocity logs. We have created software tools to leverage these sensors for a variety of tasks. Our sonar mosaicking tool combines imaging sonar data over time to build rich, detailed, and complete 3D pictures of the undersea environment. These mosaics have been used for hull inspection and ship wreck mapping. Our sonar multiview tool provides multiple means of viewing and interacting with georeferenced bathymetry data collected from a multibeam profiler, including a waterfall view, point cloud view, and map overlay. This tool allows detailed inspection of the seafloor for mission planning and site inspection. Our GPS-free navigation solution provides high-accuracy underwater navigation when coupled with the Teledyne RDI Workhorse Navigator DVL. Our patent pending process fuses multiple aiding sensors with velocity measurements to create a position estimate that is accurate to within .1% of distance traveled, enabling precise navigation even over mission-relevant distances of underwater traversal. We will discuss these tools and demonstrate their functionality and interfaces, to give a sample of some of the defense and security tasks enabled by Teledyne's sensors and Charles River Analytics' advanced software.

Vehicle-Borne Sonar for Unmanned Harbor Security

Mon, 03 Jul 2017 10:59:11 GMT

Presenter: Thomas Pastore, SPAWAR

SSC Pacific has led the development of a two-vehicle unmanned system for the purpose of inspection and identification of underwater threats in ports and harbors. The system consists of a 4-meter catamaran surface platform and a tethered submersible ROV. Thus, the combined system has the advantages of both platforms. The surface vehicle provides high speed and substantial standoff from the operator, while the ROV maintains a high-bandwidth tethered connection to surface, ability to move close to and optimize aspect to underwater threats. A joint navigation and control system accomplishes tether management and georeferencing and enables optimal positioning of the system's sensors in the water column. The subsurface platform carries a custom dual-frequency BlueView sonar, which uses a 450-kHz horizontal array and a 900-kHz vertical aperture to enable simultaneous viewing of a threat in two planes. The command and control system includes an automatic target recognition (ATR) capability. The system was initially designed to identify swimmer threats, and it has since been adapted to perform mine countermeasure) missions. This unique system can be used for many other inspection and intervention applications.

Integration of Multiple Reson and BlueView Sonar

Fri, 13 Nov 2015 12:55:46 GMT

The La Higuera project is co-owned by Pacific Hydro and SN Power and located approximately 150 km south of Santiago, Chile. The headrace tunnel known as the Tinguiririca Tunnel is 18 km in length and was constructed using drill and blast techniques.

In August of 2010, a 20-metre section of the 18 km long tunnel collapsed, forcing a 20-month long closure of the tunnel and power station while repairs were undertaken. The collapsed area was sealed off and a 260 metre bypass was constructed to reinstate water flow. During the repair of the main collapse, other sections of the tunnel were reinforced and instrumented so that real-time monitoring could be done under operating conditions. To supplement the on-line sensors, the owners required regular inspections of the tunnel to check for small rock falls, swelling of the rock mass and condition of the rock traps, preferring to do this without de-watering the tunnel. ASI Group of St. Catharines, ON, Canada, was awarded the contract to inspect the tunnel, using a remotely operated vehicle, or ROV, equipped with a unique array of Reson and BlueView sonar systems and a 10km tether to traverse the entire length of the tunnel. The data that the system needed to acquire had to match as close as possible, the level of data that the owner collected with a lidar survey of the tunnel just after the repairs were finished.

This presentation discusses the performance criteria specified by the owner and how these were met through the integration of multiple sonar systems, six of which are provided from the Teledyne group of companies, and a high-level inertial navigation system onto a modified ROV that operates with a 10 km long tether. Representative samples of collected data are also provided from recent inspections.

New Techniques for Bridge and Structure Inspection

“Combining Scanning Sonar, Laser Scanning and Mobile Mapping to Provide New Techniques for Bridge and Structure Inspection.”

By Tom Card, LandScope Engineering Ltd

Summary of paper:
With regards to bridges and other underwater structures, owners, operators and the civils industry are continually challenged to understand the structure and condition of assets below the water line. New techniques in 3D sonar are now enabling high resolution, high accuracy point clouds to be collected underwater. This presentation will discuss the challenges faced in designing data collection programmes, understand the value of combining such with traditional laser scan (LiDAR) point clouds and appreciate the advantages of this rich resource over more traditional underwater inspection techniques.
