Verlume, SubCtech Team Up on Subsea Power Systems
operations.Under the collaboration, SubCtech's battery systems can be integrated with Verlume's Axonn technology, which manages power, communications and control within a single subsea architecture.SubCtech designs and produces rechargeable lithium-ion battery systems for offshore and subsea applications, including long-duration deployments in demanding operating environments.The companies intend to use the MoU as a framework to identify and pursue further projects where their combined technologies can be deployed, rather than treating subsea energy storage as a standalone component.&ldquo
Strohm to Supply Insulated TCP Jumpers for Malaysia’s Offshore Project
place in our engineering expertise, commitment to quality, and our ability to deliver reliably at scale,” added Fabienne Ellington, Strohm’s vice president for Middle East and Asia Pacific.Thermoplastic composite pipe is a non-metallic, corrosion-resistant solution designed for subsea applications including jumpers, flowlines and risers. The technology can be installed using smaller vessels, which the company said can reduce installation costs by up to 30%
Bright Prospect: Blue Lasers for the Deep Sea
to use conventional infrared (IR) lasers to cut structures during oil platform decommissioning proved only partially practical. The primary reason: infrared radiation (wavelength 1000 nm) is completely absorbed by water within just a few centimeters, resulting in significant energy loss. For subsea applications, IR laser cutting can therefore only be performed using an air nozzle or an air-filled chamber – a complex and cost-intensive process that also prevents use at greater depths.Blue Lasers as Key TechnologyA newly developed underwater laser system based on blue diode lasers from Laserline
