SeaBat T-series Vertical Detection Mode

Wed, 28 Feb 2024 15:16:48 GMT

Vertical Detection Mode (VDM) is a game-changing enhancement now available as a free upgrade for all SeaBat T-Series sonar systems. This new feature is set to revolutionize how vertical structures are detected underwater, providing precision like never before.

Traditional multibeam sonar systems have historically struggled with accurately detecting vertical structures, often facing issues such as multipath interference, which can degrade data quality. The typical bottom detection algorithms are not designed to handle the complexity of these environments effectively. However, with the introduction of VDM, Teledyne Marine has redefined the standard for vertical-structure surveys, delivering exceptional accuracy and improving data quality, particularly in environments challenged by multipath interference from structures like sheet pilings.

VDM is engineered to conquer these challenges with a 'purist' approach. Each detection is processed to stand on its own merit, independent of adjacent beams or historical data. This ensures that true features are captured without compromise, maintaining the integrity and detail of the vertical structures.

The release of VDM comes with the SW/FW upgrade Release 3.0, which is compatible with all Teledyne RESON SeaBat T-series systems. This versatile mode is designed to work flawlessly across any frequency, pulse, or beam mode and is suitable for single or dual-head configurations. Users can now access these powerful capabilities without the need for additional licenses, changes to data output, or new configurations, ensuring a seamless integration into existing operations.

Beyond VDM, the latest software and firmware upgrade introduces a suite of enhancements and new features, including Ping Sequencing, further improvements to Tracker, and overall FW stability, all designed to augment the performance of Teledyne Marine's sonar systems.

Teledyne Marine is committed to continuous innovation and providing customers with the most advanced and reliable underwater technology solutions. The Vertical Detection Mode is a testament to this commitment, offering unparalleled detection accuracy and quality for surveyors and marine professionals worldwide.

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.

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.

Experimental verification of underwater noise localization based on...

Wed, 20 Mar 2019 13:58:27 GMT

To improve the stealthiness of underwater vehicles, or reduce impacts of vessels on the marine environment, it is necessary to identify their noise sources. Furthermore, the proper acoustic control and management of underwater noise radiation of vessels is critical during the intended upgrades and operational service.

Near-field acoustic holography (NAH) is a technology that acquires sound pressure in the vicinity of the hull, which can be back-propagated to locate the hot-spot on the hull and forward-propagated to predict the far-field radiated noise of the vessel. With OROS Underwater Holography software, which is the only underwater NAH solution in the market, the use of NAH for noise localization and far-field prediction will be presented through the findings from an experimental study on a large scaled model. Considering the typical shape of underwater vehicles, cylindrical NAH is adopted to provide the highest accuracy. A partial circular array consisting of 25 RESON hydrophones is placed in the vicinity of the hull to measure sound pressure. A shaker excited at random is mounted in the hull to simulate a source, whose location is known. The acoustic maps generated from the experimental measurements show good correlation between the hot-spot location and the known source location, verifying the correctness and efficiency of NAH technology in naval applications.

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.

Why Would You Put a Multibeam Sonar on a Construction Barge?

Fri, 19 Jan 2018 15:45:56 GMT

Abstract:

How can I use GPS – I need results in the field. I can't use RTK GPS because it's not accurate enough. Multibeam SONAR systems will never be affordable to anyone but government agencies. Why would you put a GPS unit on a bulldozer? These are all comments and questions commonly heard by and asked of the author, over the course of his career, and in their initial years of introduction, for what have all become truly transformative technologies.

Fortunate in having been exposed to each of these technologies as they were outliers at the left-hand side of the Technology Adoption Curve (TAC), otherwise known as “Innovators", the author presents a broad overview of the development and user implementation timeline of GPS and SONAR technologies. As he fills the area under the TAC with anecdotal recollections of Early Adopter, Early and Late Majority and, let's not forget – the Laggards.

Interesting enough, the technologies as referenced herein, have collectively returned to the Innovator portion of the Technology Adoption Curve. The author now hears the question, “Why would you put a SONAR on a construction barge?" Reference cases of multibeam SONAR installations on construction barges are given showing that the Early Adopters have begun filling in their “area under the curve" and the days of the Early Majority users are soon to follow.

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.

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Fri, 06 May 2016 10:34:02 GMT

By Dario Conforti - Teledyne Optech

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Teledyne Optech has been a world leader in the design, development and manufacture of advanced lidar instruments for 40 years. In the last few years Teledyne Optech and its sister company Teledyne RESON developed a full and seamless integration between their sensors, the motion-compensated ILRIS-3D laser scanner and the SeaBat 7125 Sonar System, through the PDS 2000 software. The ILRIS Motion Compensation (MC) option was developed to let surveyors use the normally static ILRIS dynamically by combining it with a Position and Orientation System (POS) and Global Positioning System (GPS) receivers. The resulting system is integrated into a mobile mapping system and enables much more effective mapping in wide and complex terrain. This type of mobile laser scanning is now at the cutting edge of coastal survey technology because it allows surveyors to easily survey coastlines directly from a boat and is particularly useful for mapping long or inaccessible coastal areas. This presentation will explain the integration of the ILRIS and SeaBat sensors and showcase several applications in the last few years from Europe to North America to Australia. The survey in Sydney, Australia is the most recent survey made and shows the perfect match between the underwater data from the sonar and the shore data collected from the lidar scanner.

“The early sonars were good then, a bit like the commodore 64 computers, but compared to the technology of today, they have a hard time.”

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.

By Hydrographic surveyor - Morten Sølvsteen, Danish Geodata Agency

Presentation outline

The two major uses of the ”skeleton”

1) Line planning
Line planning for more efficient surveys.

2) On-line analysis of sound speed profiles during data acquisition
A method for analyzing overlapping areas in multibeam echosounder surveys is introduced. The method requires that the velocity of sound at the transducer is monitored during the survey.

The method applies the principle of least squares to determine the vertical offset and the bias of the swaths caused by insufficient knowledge of the velocity of sound in the water column below the transducer.

This presentation was given at the Teledyne RESON Underwater Technology Seminar in Copenhagen 2013.

Abstract:

In 2011 Marine Surveys of Lafayette, Louisiana, conducted a series of marine geophysical surveys in the Central Gulf of Mexico. A vessel mounted high frequency multibeam echo sounder (MBES) in conjunction with a high accuracy precision positioning and inertial navigation system was used to evaluate and present the 3-Dimensional position, orientation and attitude of downed structures. A 500 kHz side scan sonar was also run at the individual sites in order to provide a traditional mapping presentation to be used as a reference and comparison to the MBES data.

The results of this survey demonstrate the value of MBES data for the purpose of mapping underwater structures and seafloor features. The water depths encountered during this series of surveys ranged up to 225ft. This water depth range allowed the survey team to perform all of the surveys at 400 kHz.
