Bathymetric Drone Survey with Multisensor Tech
Aeromedia U.A.V., S.L., a Spanish company specializing in aerial survey technologies, recently undertook a project involving a comprehensive survey of a 10-km-long corridor in the reservoir Logrosan-Caceres. The project aimed to showcase the power of integrating multiple survey technologies, including LIDAR, high-resolution photogrammetry, and an airborne echo sounder system developed by SPH Engineering, particularly for mapping terrestrial and underwater terrains.The work aimed at the topography of a water catchment and discharge area near the Ruecas reservoir in Cáceres.

Optimizing Cathodic Protection Survey Using Non-contact Sensors
be positioned higher above the pipeline and still obtain valuable data. The increased speed saves costly vessel time, while the larger measurement distance lowers the risks associated with the flight of the ROV.Crucially, the system can be used on buried, trenched or rock dumped pipelines, obtaining the same information as for an exposed pipeline. It integrates with active pipe trackers (e.g., TSS440) as the signals from the tracker do not affect the sensor readings. This feature reduces offshore time as a pre-survey with the pipe tracker is not required, resulting in significant cost savings, mainly
DNV's New Standard for Hybrid TCPs Set to Improve Deepwater Projects Reliability
DNV has released its latest standard, DNV-ST-F207 for hybrid thermoplastic composite flexible pipes (TCPs), which facilitates the integration of innovative technologies like carbon fiber armor into flexible riser designs to enhance efficiency and reliability for deepwater projects.The DNV-ST-F207 standard addresses the challenges faced by conventional risers in deepwater applications, where high top tension and corrosive environments are common.TPCs have been challenging traditional steel pipes in the last decade by offering a light, ductile, spoolable and corrosion-free solution for transportation of
CGG and Baker Hughes Form CCS Alliance
French marine seismic firm CGG has signed a memorandum of understanding (MoU) with U.S. energy services giant Baker Hughes to facilitate the parties exploring jointly offered carbon capture and storage (CCS) solutions.The collaboration and proposed commercial alliance intends to support the rapid increase of CCS projects that is underway by providing high-quality and fully integrated end-to-end solutions to screen, select, characterize and monitor potential carbon storage sites worldwide.“CGG shares a strong commitment with Baker Hughes to actively support low-carbon markets with new technologies
OPT Demonstrates Maritime Domain Awareness Solution in the North Atlantic
Marine power, data, and service solutions company Ocean Power Technologies (OPT) announced it has completed multiple offshore demonstrations for potential customers of its artificial intelligence (AI) capable Maritime Domain Awareness Solution, Merrows.The demonstrations were conducted using the recently deployed next generation PowerBuoy. Further demonstrations for additional potential customers, including overseas prime contractors, are already scheduled to occur over the next few weeks.The field demonstrations showcase the fully functional Intelligence, surveillance and reconnaissance capabilities
DNV to Publish New Offshore Rules and Standards in July
Classification society DNV said it is set to publish its new set of rules and standards for the offshore industry.The new rules, which cover several segments, including underwater systems and installations, offshore units, diving systems, structural design, and drilling systems, will be published in July and enter into force on January 1, 2025. They have been developed with extensive industry feedback, undergoing an external hearing process before their publication and entry into force.“The offshore sector is one of the most innovative in the world,” said Torgeir Sterri, Director of
Sea Drone Warfare has Arrived, and the US is Floundering
The U.S. Navy's efforts to build a fleet of unmanned vessels are faltering because the Pentagon remains wedded to big shipbuilding projects, according to some officials and company executives, exposing a weakness as sea drones reshape naval warfare.The lethal effectiveness of sea drones has been demonstrated in the Black Sea where Ukraine has deployed remote-controlled speed boats packed with explosives to sink Russian frigates and minesweepers since late 2022.Yemeni-backed Houthi rebels have employed similar vessels against commercial shipping in the Red Sea in recent months, albeit without
FET to Supply Work-Class ROV to Mexican Subsea Firm
Forum Energy Technologies (FET) has secured a contract from AQUA Exploracion to supply one its ultra compact Perry XLX-C work-class remotely operated vehicles (ROV).The XLX-C will be equipped with a comprehensive spare parts package to optimize performance and reliability.The ROV will complement and increase AQUA Exploracion’s existing capabilities and will be used to enhance subsea exploration, inspection, and intervention operations in challenging environments.The ROV has a 2,000m depth rating and, coupled with compact Dynacon LARS design, and is well suited for inspection, survey repair and
Sea Turtle Hormone Levels Affected by Deepwater Horizon Oil Spill -Study
New research is revealing potential impacts on the hormones of sea turtles affected by the Deepwater Horizon oil spill in the Gulf of Mexico.The 2010 spill, the largest marine oil spill in history, is estimated to have exposed hundreds of thousands of sea turtles to oil and killed up to 86,500 juvenile Kemp’s ridley turtles, a critically endangered species. In the aftermath of the oil spill, 319 live sea turtles were recovered from the ocean and taken to rehabilitation facilities for medical assessment and treatment. Responders collected blood samples to assess the health of each turtle, and a
