CorPower Welcomes Delegates as Portugal Looks to Advance Wave Energy Sector

demand for competitive clean energy to power industry and data centers will be best satisfied in places where the lowest cost 24/7 clean power mix can be found. Here wave energy can play a strategic role in Iberia by complementing solar and wind power to unlock some of the lowest cost of clean firm power supply in Europe.  Portugal possesses one of Europe's largest wave energy resources and has the opportunity to develop an entirely new industrial sector built around the Atlantic Ocean. Unlike solar and wind, wave energy produces electricity day and night and typically remains available when

Nexans Completes Record-Depth Subsea Cable Project in Norway

Nexans and Statnett have completed a 420 kV subsea cable project across the Fensfjord in western Norway, strengthening power supply to Bergen and surrounding industrial areas.The project, awarded in 2022, included the engineering, manufacturing and installation of two high-voltage HVAC subsea cables spanning about 7.8 km between Haugsvær and Lindås, linking the Mongstad area to Iledalsvågen.The new connection doubles transmission capacity across the fjord and forms part of broader efforts to reinforce Norway’s high-voltage grid as energy demand rises.Nexans said the project

A pressure-compensated low-frequency source is deployed by Scripps Institution of Oceanography personnel off the USS Safeguard (ARS-50), circa 1986. Note the circular source in the standing equipment cage. It is pressure compensated by the four large compressed air flasks below it. Primary lithium cells and control electronics are in the vertical cylinders flanking the source to either side. The author is pictured on the far left.

vapor. So look for a system that can provide multiple purge cycles conveniently.Sea-going teams also know that loose items need to be tied down before leaving the dock. Global Ocean Design’s Deck Purge Box is a single integrated unit, easily secured to a bench top. It incorporates a universal power supply, so it readily adapts to foreign ships-of-opportunity. There are no hazmat components such as high-pressure bottles or biohazardous chemicals. It is CE compliant. It has been in production for over 15 years, and used on housings deployed at all latitudes and all depths, for short and long durations

Battery Power Management and Control

timer that outputs a 1.5v signal to a piezoelectric beeper. Bring the signal for the beeper to the gate of the NTE5455 instead to start a 10vdc source corroding a burnwire.SequencerPowering up multiple parallel circuits might be challenging due to initial in-rush currents. The TI LM3880 Simple Power Supply Sequencer is a device that controls power up and power down sequencing of three independent voltage rails. By staggering the startup sequence, the instantaneous battery loads are moderated. The robust part is qualified for automotive applications and features a low quiescent current of 25 &mu

approach to scalable, “disruptively affordable” autonomous maritime systems.SubSeaSail’s HERMES, meanwhile, is a scalable, self-righting, semi-submersible trimaran designed for long-duration surface and subsurface operations, and is envisioned as a cargo and expeditionary power supply platform. Like HORUS, HERMES can submerge to 100 meters to evade detection or ride out severe weather. With speeds of 5 to 15 knots, and large-volume payload space, it offers a high-speed, attritable platform for contested logistics.The HERMES.

This includes 255 kilometers of undersea cables across Bass Strait and 90 kilometers of underground cables in Gippsland, Victoria.Marinus Link’s 1,500MW capacity is equal to the power supply for 1.5 million Australian homes and approximately three times the capacity of the existing Tasmania to Victoria interconnector, Basslink.Marinus Link will be delivered in two stages. Initially as a 750MW project (Stage 1) with a second 750MW link to follow at a later date (Stage 2).The project

Offshore Solar Farm Set for Integration with Dutch Offshore Wind Project

farm has been completed at the Port of Amsterdam in a ‘world’s first’ project that will integrate the system with an offshore wind farm in the North Sea, offshore Netherlands.The system, supplied and built by Oceans of Energy, is larger than a football field and is set to integrate power supply at 759 MW Hollandse Kust Noord offshore wind farm in summer 2025.The wind farm, operated by Crosswind, a joint venture by Shell and Eneco, is located 18.5km offshore in the North Sea.The assembly of the offshore solar farm has been completed at the Port of Amsterdam, and the system is ready for
