BIRNS High Amperage Connector Series Debuts
amperage subsea connector series, the 225 Amp BIRNS Meridian line.The Meridian line, a robust, custom engineered dry-mate connector series is open face rated to 6km, and is well-suited for battery packs and thrusters for crewed and uncrewed subsea vehicles that require high amperage power transfer. Select sizes are already being DNV type-approved for 6km rated crewed submersibles. BIRNS Meridians are compact, and feature several pin configurations, with more in design for release later this year. The M40 pin configuration has a single 85 square millimeter/3-000 contact. Both standard and reverse gender
PODCAST: “All in the [Gallaudet] Family”
her father’s love of the oceans [and not to mention that her mother Caren was also a Naval Academy graduate, an oceanography major and a navy salvage diving officer] and in this first episode she discusses with her father and life-long mentor the ins and outs of his maritime career.Following are a select few excerpts from View from the Helm, Episode 1, “All in the [Gallaudet] Family”. But the real story here far transcends RAdm Gallaudet’s career and his insights on emerging marine technologies. The real story is the man and the family behind the mission, a career dedicated
Fincantieri and EDGE to Launch JV for Naval Vessels Construction
billion (€30 billion), with management direction provided by Fincantieri.The Abu Dhabi-based JV will be awarded prime rights to non-NATO orders, especially leveraging on the attractiveness of UAE G2G arrangements and export credit financing packages, along with a number of strategic orders placed by select NATO member countries, the companies said.Thie agreement - signed on February 21 by Hamad Al Marar, EDGE’s Managing Director and CEO, and Pierroberto Folgiero, Fincantieri’s CEO and Managing Director - grants the JV strong cooperation to market its products with the Navy of different
US Invests Nearly $16 Million to Advance Marine Energy
The U.S. Department of Energy (DOE) has announced two marine energy projects will receive a combined $6 million to develop a tidal energy research, development, and demonstration pilot site in the United States.In addition, a community-led river current energy research and development project was selected to receive $9.5 million.Tides and currents are incredibly predictable, meaning these resources could help balance other sources of renewable energy and be important contributors to a 100% clean energy grid. This funding, supported by the Bipartisan Infrastructure Law, encourages U.S. leadership
Glosten, Siemens Energy Select Key Equipment Vendors for World's First Hydrogen-hybrid Research Vessel
Naval architecture and marine engineering firm Glosten and Siemens Energy have selected Ballard Power Systems and Chart Industries as primary equipment vendors for their design of what will be the first hydrogen-hybrid research vessel in the world. The vessel, nominally known as the CCRV, is currently in the design phase and will be owned and operated by UC San Diego’s Scripps Institution of Oceanography (Scripps). Ballard Power Systems will provide the fuel cells which will help power the vessel, and Chart Industries will provide the cryogenic tank and fuel gas system where the liquid

design to enhance marine biodiversity around these structures.What’s next?Several companies are actively exploring, or indeed constructing, underwater data centers. While the average end-user will have no real awareness of where their data are stored, organizations may soon have opportunities to select local, underwater cloud platforms and services.Companies with a desire to shout about their environmental credentials may well seek out providers that offer greener data centers – a change that is likely to only accelerate the move to the ocean.So far, it looks like this approach is practical

;$9 plus shipping at <www.mpja.com>.If using a MOSFET as a high-power switch to control the lights, look for the RDS(ON) value, “Static Drain-to-Source On-Resistance.” This is the voltage (VGS) that needs to be applied to the gate to fully switch the MOSFET on. Depending on the part you select, this will be between 4v to 10v. I look for MOSFETS that fully saturate at logic levels of 5v, such as the IRL540. A helpful review of MOSFET circuits is found at <www.electrical4U.com/mosfet-circuits/>. A useful MOSFET worksheet is at <www.addohms.com/mosfet-guide/>.Figure 4. A Global
NOAA to Award $28 Million to Tackle Marine Debris
and maintenance of proven marine debris interception technologies that will capture marine debris at or close to known sources or pathways. Letters of intent are due on November 15, 2023.These two funding opportunities will be reviewed separately and have different application requirements. NOAA will select projects through a rigorous and highly competitive merit review process.“Investments from the Bipartisan Infrastructure Law are critical to reduce the impacts of marine debris, remove legacy debris from the environment and prevent future debris from accumulating in order to reduce stress on
Gardline's Horizon Geobay Vessel to Support Ocean Winds' Geotechnical Survey in Moray Firth
Moray Firth throughout its decade-long presence in the area. Our goal now is to build a clear picture of the ground conditions across the Caledonia site area to inform the engineering design of the project. Collecting this data is an essential part in determining the wind turbine foundations, ensuring we select structures suitable for the site."The offshore campaign will run until the end of 2023 (weather dependent).Caledonia is a 2GW project developed by Ocean Winds in the Moray Firth, and one of the few ScotWind sites scheduled to be operational by 2030. It is adjacent to Ocean Wind's operational
