A submerged dock lays off the Fort McHenry National Monument, in the Patapsco River, Baltimore MD—and a well-known marked hazard zone. The depth surrounding the object is navigable at depths greater than 30 feet. Just over the hazard, depths are only 5-8 feet, making it impossible for a traditional survey vessel to navigate. We chose this particular location to demonstrate how an ultra-high resolution multibeam sonar can be used in conjunction with a small autonomous surface vehicle (ASV) to obtain a more complete survey of a complex and challenging area.
Technology is moving fast with always the “more accurate, cheaper, smaller” dictate. Three years ago, SBG Systems has been able to integrate all those wishes into a single unit: the Ekinox Inertial Navigation System (INS). In 2015, SBG Systems took another step forward with the release of the Apogee, the most accurate inertial navigation system based on the robust and cost-effective MEMS technology. Without export restriction, the Apogee stands as a game changer on the hydrographic market. It provides an unmatched Performance-Price-Size ratio and sets up new standard in the industry. Let’s see how MEMS-based inertial sensors can be used in some of the latest technical solutions dedicated to hydrographic surveyors.
The Canadian Hydrographic Service (CHS) and Teledyne CARIS™ conducted two important sea trials in July and December of 2015. The July trial was to test the capabilities of CARIS Onboard™ for near real-time processing, while the December trial was focused on remote access to the products created through a remote survey operation.
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.
