EC-OG Raises Funds for Subsea Battery System

Subsea clean energy company EC-OG has said it has received £1.6 million from an investment consortium led by Par Equity. The company plans to use the cash to commercialize its innovative Halo battery storage system designed for subsea applications. "The investment will create up to 40 jobs in Aberdeen over the next 12 months," EC-OG said.Halo is a modular and scalable battery storage system that operates in a demanding subsea environment. "By removing the need for undersea power cables, [the battery storage system] provides a reliable, uninterrupted power supply, located

portfolio includes single and multibeam echo sounders, sonars, underwater vehicles and subsea transponders and positioning systems, in addition to software and solutions for defense customers. In line with other marine sectors, Kongsberg Maritime is also at the forefront of digitalization for subsea applications. Mapping Cloud, which provides easy storage of different types of data within the Cloud, offers an accessible and practical means of uploading and distributing real-time data, which can be subsequently made available to use in diverse applications and products. The company continues to excel

and application-specific tasks. The S2C M “mini” devices are smaller and lighter, providing essential builds for numerous communication and positioning scenarios. The new S2C T - the “tiny” line - steps up to enable smarter, lighter and more effective solutions to modern subsea applications that demand fast and reliable communication packed into a compact design

there exists significant need for cost-effective remote offshore power and communications.”OPT's PowerBuoy and subsea battery solution product lines, along with its support services, provide clean and reliable electric power and real-time data communications for remote offshore and subsea applications.Kirby said the company sees big opportunities in the U.S. Gulf. “The Gulf of Mexico is the largest oil field decommissioning market in the world with more than 9,000 wells that require plugging and abandonment. Many of these wells are in deep water, where high cost and complexity drive

“We are moving autonomous technologies into vehicles that have always been "remotely operated" or even manned to realize more efficiency and capability.  We are really blurring the lines between "ROV" and "AUV" and minimizing the technical difference between manned and unmanned. ”

intends it to do, easily.”AUVs“Two years ago I attended a workshop at Rice University moderated by the Subsea Systems Institute where major oil & gas companies, their providers, and underwater vehicle manufactures spent the day generating a development strategy for AUVs for subsea applications,” said Bob Melvin, the Vice President of Engineering at Teledyne Marine Systems.  “Their number one requests was to make underwater systems that can perform subsea tasks.  To reach this goal there is acknowledgement that the commercial sector will need to leverage advances

safe operations, deeper dives, longer observation times, and lighter units. The oil and gas industry at large demands electronic control, electrical drives, precision and condition based monitoring feedback, and long-life sensors and monitors for their deepwater systems.In short, innovative subsea applications are getting smarter and going untethered…and untethered subsea operations require batteries that are safe, smart, provide more capacity, deliver more power, are smaller and lighter, longer life, and highly reliable.For years, most electrical subsea operations were tethered, powered

DNV GL to Test Bolt Fatigue for API

DNV GL said it has secured a contract from the American Petroleum Institute (API) for the full-scale S-N fatigue testing of large diameter bolts. The objective of the program is to improve fatigue assessments of critical bolted connections particularly in subsea applications by generating new test data.S-N Fatigue testing is the graphical presentation of the dependence of fatigue life (N) on fatigue strength (S). The testing will take place in a strictly controlled environment within DNV GL’s global laboratory network involving its sites in Columbus, Ohio and Norway, which provide extensive
