From surface to seafloor, Valeport innovative profilers are shaping the future of surveying
Established in 1997, Bibby HydroMap provide a range of hydrographic, geophysical, geotechnical and ROV survey services to clients mainly from the oil and gas, offshore renewables and subsea cables industries. Their fleet of dedicated survey vessels work throughout the UK and Northern Europe, are permanently mobilised with high-specification survey equipment from industry leading suppliers.
In the following article Teledyne Marine Imaging introduces its Hydrographic solutions and capabilities, analyses the rapid development of Hydrography over time and highlights the key Teledyne Marine markets, supported by case stories. Finally, we will describe the future trends within hydrography.
If you look closely at any U.S. coastal nautical chart, you’ll likely find that the areas closest to the shore, shoals, and rocks do not have updated depth measurements. In many areas, safety concerns prohibit the use of NOAA ships or launches to survey shallow depths. In many areas, the water is too murky to be mapped with the airborne lidar systems used in clear waters. Now, however, charting those shallow areas is about to get safer, thanks to recent purchases of small, commercial off-the-shelf, unmanned survey vessels.
Copenhagen Subsea A/S is a newly created company with the purpose of bringing a range of innovative products to the subsea industry. The products are based on many years of experience with building products for the demanding subsea industry.
Ocean X Team’s main focus is to search for hidden treasures such as antique high-end alcoholic beverages and historic artifacts. They started their wreck career by finding an American B-17 bomber in 1992 off the Swedish east coast.
Autonomous, tethered, and towed vehicles are doing important work in defense and security, oceanographic research, offshore and onshore energy, and water resource markets. In fact, unmanned underwater vehicles have become an essential tool for a variety of tasks across all these markets, which is a testament to the evolution of robotics technology. Underwater unmanned vehicles are doing work that is impossible, expensive, or clearly too dangerous to humans.
Over the last few months, VideoRay LLC has rolled out two new additions to their product line – the VideoRay Voyager, an economy ROV system, and a brand new line of customized ROV systems called the Mission Specialist Series.
Micro Electro-Mechanical System (MEMS) technology is at the heart of Teledyne CDL’s extensive range of motion sensors that includes a variety of specifications, accuracies and external aiding capabilities. Also available is a complete range of fibre optic gyro (FOG) and ring laser gyro (RLG) gyrocompasses, built for marine vehicle navigation. This wide range of commercially available products is mainly for use in subsea marine and in particular, remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs). CDL products are also suitable for subsea gliders, offering combined motion and navigation requirements for all subsea vehicles.
Do you remember navigating with a street atlas? What a difference GPS makes. And now it seems every other new gadget includes a GPS chip for supplementary input. Similarly, better navigation tools optimized operations that use unmanned underwater vehicles (UUVs). Plus better navigation permitted expanded capabilities and greater cost-effectiveness. Together these advantages delivered a major gain for users of tethered and untethered UUVs. These are Remotely Operated Vehicles (ROVs) and Autonomous Underwater Vehicles (AUVs).
Since 2005, Teledyne Marine has grown in size and scope, adding technology and capabilities through organic growth and acquisition. Now twenty three brands strong, Teledyne Marine is recognized as a preeminent leader in marine technology, delivering a vast spectrum of product solutions and technologies to resolve challenges in some of the most demanding scenarios and environments imaginable.
Unmanned maritime vehicles (UMVs) have been under development for decades. Since the late 1990s, several systems have evolved beyond research labs and have become commercial realities. These tools are now in routine use for scientific, commercial and military applications.
Over the past years, multibeam echo sounders are increasingly being used not only to obtain water depth information, but also to record backscatter response. This information recorded by the sonar is very useful in studies on marine geology (Anderson et al., 2008; Harahap et al., 2010), underwater works and military applications, as it is possible to relate the acoustic intensity response with ocean floor properties(Applied Physics Laboratory, 1994; Eleftherakis et al., 2012; Huang et al., 2011).
HYPACK, Inc. has been a world leader in software development for the hydrographic and dredging industry since 1984. HYPACK® is the most widely used hydrographic software package with over 10,000 users worldwide. It provides everything necessary to fulfill your singlebeam, side scan, and multibeam survey requirements. This is why?
AML Oceanographic’s recently released WiFi & GPS device, Data•Xchange, is saving time for hydrographers around the world by transferring and exporting data wirelessly and automatically.
The acquisition of QPS by Saab opened up for the possibility for closer integration between the Saab AUV platforms and the data acquisition software from QPS. This resulted in a joint project in 2014 to demonstrate a high end survey system that was capable of very accurate combined sonar, multibeam bathymetry, video and subbottom profiling. The system is based on Saabs hovering AUV capable of very stable autonomous close up scanning of both structures and bottom features. The QPS data acquisition software ensures that all data is collected together with navigation data in an optimal way for precision and further processing. The result is merged data of high quality that is easily evaluated and exported.
