Navy Signals Need for New Large AUV Class
largest UUVs are the Boeing XLUUV and Snakehead LDUUV. The Navy accepted delivery its first Extra Large Unmanned Undersea Vehicle (XLUUV) Test Asset System in December 2023. The Boeing Orca XLUUV, designated XLE0, from the manufacturer Boeing.The Orca XLUUV is a cutting-edge, autonomous, unmanned diesel-electric submarine with a modular payload section to execute a variety of missions critical to enhancing the Navy’s undersea prowess. Configured to accommodate various payloads, the Orca XLUUV allows for the seamless integration of sensors, communication systems, and other mission-specific
ASL Environmental: Tidal Currents Study Underway in Newfoundland and Labrador
successful completion of an initial multi-week study to measure tidal currents in collaboration with the Nunatsiavut Government and Oceans North. This initiative aligns with the Nunatsiavut Energy Security Plan to explore clean, renewable energy solutions for coastal communities and reduce dependence on diesel-generated electricity.Current transect surveys were initially carried out with Acoustic Doppler Current Profilers (ADCPs) over the broader study area. ADCPs were then deployed on moorings at three strategic locations within the Rigolet Narrows waterway and recovered in September 2024. The data from

research across the entire marine ecosystem, using advanced technology systems.Scientists and other experts will use it for research expeditions, seeking to solve issues related to the impact of CO2 emissions, plastic pollution, and unsustainable fishing on the ocean.The vessel is constructed to run on diesel-electric engines, with an additional 3 MW lithium-ion battery pack for peak shaving, ensuring optimum efficiency onboard.An independent science and innovation board will evaluate and recommend research projects for REV Ocean to pursue and ensure the highest scientific standards and research quality
AiP Granted for Autonomous Subsea Inspection USV
2 (DP2) capability, the vessel can deploy a work-class electric ROV at depths of up to 2,500 meters. Its ability to perform multiple tasks offers the potential to streamline workflows, minimize operational downtime, reduce costs, and enhance the overall efficiency of offshore projects.Powered by a hybrid diesel-electric system with the potential for future migration to hydrogen, the USV significantly reduces carbon emissions, and meets the demand for sustainable solutions in offshore operations
Baker Hughes Launches All-Electric Subsea Production System
land cementing unit and SureCONTROL Plus interval control valves for enhanced control.All of these technologies will have implications for both traditional oil and gas and new energy applications.The Hummingbird all-electric land cementing unit is an industry-first, 100% electric solution that replaces diesel engines with grid-connected or battery-powered motors. The Hummingbird’s dual-power functionality performs onshore cementing operations with lower emissions and noise levels compared to traditional solutions. SureCONTROL Plus interval control valves (ICV) enable electrical remote operations
Shipbuilding RFP Issued to Build Hydrogen-Hybrid Research Vessel
issued a request for proposals (RFP) to select a shipyard for the final design and construction of its new 163-ft. Coastal Class Research Vessel (CCRV), reportedly the first oceanographic research ship to primarily operate on renewable fuels.The vessel will feature a dual-powered hydrogen fuel cell and diesel-electric propulsion system, capable of conducting 75% of its missions using only liquid hydrogen. When running on hydrogen, CCRV will produce zero emissions and operate with minimal noise, ensuring contamination-free sampling and enhanced performance of its underwater acoustic sensors.“This
Next Geosolutions Buys Offshore Survey Vessel for $7M
$7.1 million.The vessel, Sea Admiral, will be renamed NG EXPLORER, and will be used for geophysical, geotechnical, environmental and UXO surveys.The NG EXPLORER, with a length of 58 meters and a width of 14 meters, is an MPSV built in 2010 and equipped with a Dynamic Positioning Class II (DP2) system and diesel-electric propulsion that will raise the Italian flag and be operational from the first quarter of 2025.The ship will undergo refitting work, with an additional investment estimated of up to $5.2 million, in order to make it even more efficient and functional for the high-tech activities for which
