The Teledyne Marine Channel

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.

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.

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.

Abstract:

Teledyne PDS software can be used for a variety of marine applications, both in construction and hydrographic surveying. This presentation will focus on a relatively new feature for the Teledyne PDS software, pile driving. Whether it is standard vertical piles or complex battered piles, PDS easily manages the workflow. The operator is given all pertinent information to in real-time displays to speedily and accurately position the piles, such as an overhead bullseye view with vessel-referenced change required distances and a 3D view showing current and design pile locations. Included in the presentation will be an overview of the Teledyne PDS software for those unfamiliar with it, a short walkthrough of project creation and vessel setup, and a demonstration of real-time operation. This will be followed up with results from Teledyne PDS pile driving in the field.

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.

Video paper: Pipeline surveying from a surface vessel in the Caspian sea

Mon, 25 Nov 2013 12:49:39 GMT

Surface Vessel Based Multibeam Pipeline Inspection

In a special collaboration between BP, Fugro Caspian and Teledyne RESON an unconventional approach was used to survey pipelines in the Caspian Sea. A vessel was outfitted with two pole mounts each equipped with a SeaBat 7125 SV2 using FP3. Teledyne PDS software was used to automatically detect and track the pipes in real time. A total of 710 km pipe was surveyed in just seven days. This presentation outlines the advanced technologies that were involved to collect such high resolution pipeline data.
