Geoquip Marine Adds Retrofitted Vessel to Its Geotechnical Fleet
site investigations in a range of sea states.Once the upgrade is complete, the Geoquip Silvretta will mobilize for a project in northern Europe, Geoquip Marine said.The Geoquip fleet’s newest addition, was built as a DP2 vessel and no changes are planned to the propulsion, main components or machinery.However, Green Yard will work with the vessel’s original designer, Marin Teknikk, to customize the interior for Geoquip’s global projects.These upgrades will include installing a moonpool, moving and adding cranes, extending the shelter deck, increasing office and meeting space, and

Underwater Radiated Noise and Ocean Health
noise originates from various sources, with cavitation from propellers being the most significant contributor. Cavitation occurs when water vapor bubbles form and collapse near the propeller blades due to pressure changes, releasing energy in the form of sound. This constant hum of cavitation and other machinery adds to the ambient noise in the ocean, contributing to a long-term increase in sound levels.Since the 1930s, studies have indicated that URN levels have risen by an average of three decibels per decade, largely driven by shipping activities. This steady increase disrupts the natural acoustic environmen
Acteon’s MENCK Launches Wind Hammer Pile-Driving Tech for Offshore Wind (Video)
responsible installations, significantly reducing noise, pile fatigue and operational costs.Key features include a double-acting hydraulic drive, closed-loop control, shock absorber cartridges and comprehensive safety mechanisms.By driving a larger hammer at a lower energy, the Wind Hammer reduces machinery wear and tear and minimizes underwater noise, to support a sustainable offshore environment, according to MENCK.As the MHU 6000W machinery is connected to MENCK’s real-time digital and data platform, the machine draws on decades of pile-driving experience and places that knowledge at the
Hydrogen-Hybrid Research Vessel Earns AIP
Resource Board (CARB)-compliant, ABS-classed vessel and an alternative design under SOLAS, the CCRV faced acomplex regulatory regime.“Our challenge was to harmonize the requirements of a modern research vessel with evolving regulations and novel technologies for liquid hydrogen fuel. Ensuring the machinery spaces and hydrogen systems were efficiently and safely arranged without compromising the utility of thevessel was like putting together an intricate puzzle,” said Robin Madsen, the lead marine engineer on the project for Glosten.In 2018, Glosten, Scripps Oceanography, Sandia National Laboratories
How Do You Build Tunnels and Bridges Underwater?
it. Done with care, this method can successfully build a tunnel through the ground beneath a body of water that can then be lined and reinforced.Engineers used this method to build the Chunnel, for instance, a railway tunnel beneath the English Channel that connects England and France.While modern machinery is quite advanced, this method of construction started about 200 years ago with the tunneling shield. Initially, these were temporary support structures that provided a safe space from which workers could excavate. New temporary structures were built deeper and deeper as the tunnel grew. As the
