FLASC, Subsea 7 Working on Non-battery Energy Storage Solutions

air to create an efficient, large-scale energy storage device that can be applied across a wide range of offshore applications.The first working prototype was successfully tested in 2018, and the technology has been granted a Statement of Feasibility based on a technical and commercial assessment by DNV-GL."The collaboration combines the innovative concept definition capabilities and specialized HPES system expertise of FLASC, with the proven subsea solutions, technologies, and experience of Subsea 7, towards the commercialization of offshore HPES," FLASC, a spin-off from the University

“Environmental’ limits are available which are aimed at reducing underwater noise emissions without imposing onerous design limitations and the need to put damping on every panel, stiffener & dinner plate.” Jesse Spence, President, NCE

Mitigating Underwater Noise

equipment.”When asked define ‘top tips’ to mitigate underwater noise, Spence admitted “Really, I have one. Put a limit in your vessel specification and require the vessel to be designed to meet it. There currently are a variety of underwater noise classifications from ABS, Lloyds, DNV GL, and others. Environmental’ limits are available which are aimed at reducing underwater noise emissions without imposing onerous design limitations and the need to put damping on every panel, stiffener, dinner plate, etc. The more these limits are used the more we will learn about what it takes

"World First": Remote In-water Ship Surveys via ROV

As COVID-19 continues to challenge many business plans and practices, the advent of remote inspection techniques is growing in popularity. What is reported to be the world’s first in-water remote ship surveys using a remotely operated vehicle (ROV) have been completed by DNV GL.In-water bottom surveys using ROVs have now been carried out on three separate Wilson ASA-managed vessels with the first having been completed on the Wilson Fedje in December 2019 by a surveyor from Høvik. The survey was performed earlier in July on another ASA Wilson-managed vessel in Bergen, Norway. Elias Triantafy

World's Most Powerful Wind Turbine Hits Key Milestone

The world's most powerful wind turbine in operation, GE Renewable Energy’s Haliade-X 12 MW prototype, has reached an important milestone.Namely, classification company DNV GL has granted it a provisional type certificate (IECRE Provisional RNA Component Certificate) which demonstrates GE’s Haliade-X prototype has the highest safety and quality standards and provides evidence that its design is on-track to meet the full type certification requirements.Testing activities of the 107-meter long blade currently taking place at UK’s Offshore Renewable Energy (ORE) Catapult in Blyth

VIDEO: Drone Inspects FPSO Tank. It Could Soon Do It On Its Own

drones could soon be used for tank inspections on offshore installations, with data immediately analyzed by AI. This would boost safety and cut costs, as the need for scaffolding, and for technicians climbing on an into tanks for inspection would be eliminated.Drone company Scout Drone Inspection and DNV GL, the quality assurance firm company, that have been working together to develop an autonomous drone system to cut inspections costs, and to increase safety, have this week shared a major milestone in this area.DNV GL said Tuesday that a drone - controlled by a pilot - had successfully inspected a

Are O&G Digital Twins Useful? DNV GL Moves to Find Out

Offshore classification and technology advisory group DNV GL has set out to test and see if Digital Twin technology and data can be trusted and if they deliver value.The Norway-based firm has thus launched an international call to oil and gas operators and the supply chain to pilot a methodology to prove the value of the technology.Companies manufacturing hardware across the oil and gas value chain must prove the safety, quality and integrity of components, equipment and assets through recognized quality assurance principles. However, no standard process exists to provide the same mechanism of trust

The Path to Zero: Creating a Pathway to Carbon-Negative Shipping

fossil fuels may become carbon free.MDC sees analogies between the IMO’s 2020 sulfur regulations and the 2050 zero-carbon target: “The expected energy penalties in adopting a zero-carbon strategy are low – it’s a ‘no-brainer’,” said Henrik O. Madsen, former DNV GL President and CEO. “Shipowners should take responsibility and not compete but collaborate in the area of carbon footprint reduction to meet the 2050 zero-carbon target. In my opinion, this is an area that is far too important to become the victim of competition – this is a problem for
