CSA Completes Field Surveys Offshore Puerto Rico

CSA Ocean Sciences (CSA), under a subcontract to Jacobs, has announced the completion of a comprehensive environmental monitoring survey. The survey included physical, biological and chemical field sampling and data collection for 301(h) waiver demonstrations at the Aguadilla, Arecibo and Ponce Regional Wastewater Treatment Plant (RWWTP) outfalls offshore Puerto Rico for the Puerto Rico Aqueduct Authority (PRASA). Since 1999, CSA has been helping to evaluate compliance with receiving water quality standards and describe environmental conditions. Acoustic Doppler Current Profilers During this recent survey, CSA deployed and retrieved acoustic Doppler current profilers (ADCPs), a conductivity-temperature-depth (CTD) water profiler with ancillary sensors...

Optimizing a Low-cost Multi Sensor System for Hydrographic Depth Determination

Surveying devices with lower costs are being welcomed by hobbyists eager to determine water depth. The Department of Geodesy and Geomatics at HafenCity University (HCU) in Hamburg has been working on cost-efficient solutions in recent years. With shallow water surveys not required to be performed with the accuracy and precision of industrial projects, surveying devices with lower costs are being welcomed by hobbyists eager to determine water depth. With this low-cost demand rising, the investigative development of these products has become a scientific research issue. The Department of Geodesy and Geomatics at HafenCity University (HCU) in Hamburg has been working on cost-efficient solutions in recent years.  The Old Openseamap Project During a project with openseamap.org, a Multi Sensor System (MSS) including an Echo sounder, GPS and inertial measurement unit (IMU) was built up and tested. Despite... (read more)

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...
