Fusion 2 – An Evolution in Offshore Survey Operations

Complex set-up operations, multiple topside systems and interfaces, and arduous workflows; these are all now in the past. Sonardyne’s Fusion 2 survey software combines intuitive workflows with faster, more flexible INS, LBL and Sparse LBL aided INS operations - all from a single system. Since surveyors and subsea construction operatives took their first steps into the US Gulf of Mexico, followed by the harsh waters of the North Sea and beyond, the industry has been on a learning curve. From taut wire through to today’s digital signalling architectures, systems and methodologies, the industry has evolved. Developments in signalling technology have... (read more)

Advances in High-speed Underwater Remote Vehicles for Subsea Pipeline Inspection

The Benefits and Challenges of the Technological Revolution in the Pipeline Survey Industry
The pipeline survey industry has undergone a technological revolution in the past couple of years, and the consequential benefits and challenges are only just beginning to be fully realized. The cost efficiency of subsea operations has been one of the key focus areas of the offshore energy industry in recent years. This focus, combined with increased growth in the amount of subsea infrastructure now in-situ on the seafloor, has seen a rising need for innovative approaches to subsea asset inspection. These solutions need to be cost-efficient, maintain data quality, and be able to provide a platform that supports future technologies.... (read more)

Sonardyne’s PIES to Monitor Disruptive US Gulf Current

Oceanographic equipment developed by underwater technology company Sonardyne International will be used as part of a major US$2 million scientific study of disruptive ocean currents in the US Gulf of Mexico. The multi-year deployment, led by the University of Rhode Island (URI)’s Graduate School of Oceanography, will monitor the Loop Current System (LCS) using Sonardyne’s Pressure Inverted Echo Sounders (PIES). The LCS is the dominant ocean circulation feature in the Gulf of Mexico. It influences all ocean processes in the Gulf and has implications for a wide range of human and natural activities, from oil exploration to coastal eco-systems, but,... (read more)

Cartography at the Source

New Products, New Ideas, Less Work
For two decades, CARIS’ hydrographic production database solution has enabled geospatial data to be managed in a data centric manner, while allowing various types of products to be created and updated from this one data centric source. A large user base of hydrographic offices worldwide has utilized this capability to produce and maintain a large percentage of the world’s paper charts and ENCs. Over time, the advantages of deriving products from one source has led to the introduction of more product types being produced by the system. Expanding from paper charts and digital chart products (such as ENCs and AMLs)... (read more)

Seafloor Based Seismic Cable Permanent Reservoir Monitoring with Sonardyne Sensors

Norwegian energy firm Equinor is to deploy cabled subsea instrumentation from Sonardyne International to help increase the accuracy of time-lapse seismic data at the giant Johan Sverdrup oil field. From the first production of the development, Equinor plans to use seafloor based seismic cable permanent reservoir monitoring (PRM) technology to observe what is happening in the reservoir over time to help maximize recovery rates. While PRM technologies increase the amount and data quality that operators have about their reservoirs, processing it can sometimes be complicated by changing environmental conditions, such as water velocity and tidal height, at the time each survey...

TCarta Wins Contract to Map Seafloor around Kiribati

TCarta Marine, a global provider of geospatial products and services, has been contracted by the United Kingdom Hydrographic Office (UKHO) to provide a baseline dataset of water depths and seafloor classification around the Republic of Kiribati. Located in the Pacific Ocean, the island nation is threatened by rising sea levels. “Most of Kiribati’s islands average less than two metres above sea level at present and the country’s 110,000 inhabitants are among the most vulnerable to the effects of sea level rise and the world’s first potential climate change refugees,” said Kyle Goodrich, TCarta President. “We expect to map 5,000 square...

Web GIS Improves Lidar Collection Response Time

The remarkable capabilities of airborne Lidar continue to improve, with scanners now able to emit more than a million pulses every second. Although it has never been easier to acquire high-quality laser data, storing and managing the huge volume of Lidar data collected can prove to be a challenge. Combined with associated metadata such as survey information, environmental conditions and flight lines, data management has now become a critical priority and focus. This article outlines an initiative called the Lidar Management and Analytical Processing (LMAP) that provides an automated workflow for uploading and storing Lidar and metadata into a Geographic...

Design to Deployment - ToughBoy Wave Buoy

When using sea-going equipment, the elements are invariably one of your greatest adversaries. Whether a researcher waiting for a weather window, or a technician maintaining a sensor platform, the waves and weather should never be underestimated as sensor equipment must endure these conditions. Wave buoys represent a considerable design challenge from multiple perspectives. Physical durability is clearly of fundamental importance, but that robustness must be extended into the functionality and performance of the wave buoy system. A wave buoy must also maintain operational independence over extended periods of time – measured not in weeks or months, but often years. The... (read more)
