Longer-Endurance CTV with 'Sleep Aboard' Capability Unveiled
.At 35.4m long, HybriNav35 is designed to cater for increased endurance of up to two weeks, where crew will be able to sleep onboard the vessel. This design specification will enable the vessel to support infield transfers and transits between sites 24/7 in O&M and Construction on far-offshore locations.The design shares some similarities with the previous HybriNav26 in that both vessel designs have a unique hull design, which allows them to be tailored to clients’ requirements. The 26m design has waterjet propulsion, whereas the 35m design has a variable pitch propeller. Both vessels are
CSignum Launches New Wireless Underwater Comms Device
empowers industries to explore, monitor, and protect our waterways and subsea environments with unprecedented efficiency and reliability."The company says that the EM-2 enables real-time data transmission from beneath the surface to shorelines or riverbanks, and even through ice or underground locations. With bidirectional data transfers of up to 200 meters, EM-2 ensures successful deployment in both saltwater and freshwater environments. Its unique electromagnetic field-based communication method enables effective data transmission through mixed media scenarios.The versatility of EM-2 lends itself
Optimizing Cathodic Protection Survey Using Non-contact Sensors
all pipelines and subsea structures across an entire field. Combined with new cloud-based online reporting and visualization, FORCE Technology can provide a central portal for information on all CP at an entire development or even multiple developments. This can unlock new savings across assets and locations by informing a decades long data-driven maintenance program based on highly accurate lifespan prediction for every CP anode protecting the entire subsea infrastructure

DEME Scoops ‘Most Extensive’ Cabling Contract in Its History
well as pre-sweeping and rock placement works for the Nederwiek 1 project.DEME will deploy a variety of vessels from its fleet, including cable installation vessels, hopper dredgers and a fallpipe vessel. In addition, the project will cover the beach works and cofferdam structures at the cable landing locations.The works are scheduled to begin in stages from 2025.IJmuiden Ver Alpha and Nederwiek 1 are offshore grid connection systems operated by TenneT that will link two future offshore wind farms in the Dutch North Sea to the province of Zeeland in the southwestern part of the Netherlands.The first connection
Over 50 Species New to Science Found Along Salas y Gómez Ridge
documented in hydrographic surveys.The information collected during the expedition will provide the scientific basis to inform the management of existing marine protected areas and potentially expand them, especially around the island of Rapa Nui.The Salas y Gómez Ridge is one of several global locations under consideration for designation as a high seas marine protected area upon ratification of the UN High Seas Treaty. Parts of the ridge within Chile’s national jurisdiction are protected. However, much of the ridge lies in international waters. While many countries, including the United
New Electrochemical Technology Could De-acidify the Oceans
(around 30 per cent) of the capital cost and have short lifetimes as they are susceptible to degradation.Our work aims to develop scalable, ultra-thin membranes for use in a modified BMED process, while also identifying efficient operational conditions, optimal industrial couplings, and ideal global locations to cost-effectively implement this OAE technology around the world.The ultra-thin membranes will extract acidity more efficiently than existing commercial membranes, while their manufacturing technique and optimal usage will dramatically decrease their production and operational costs.Developing
Design Images of World’s First Long-Range Autonomous Research Vessel Released
of monitoring sensors to collect data for research into areas such as climate change, biodiversity, fisheries and biogeochemistry. The vessel will be able to reach remote areas of the ocean that are difficult or impossible to sample through traditional research vessels, whether due to remote locations or due to extreme weather conditions. PML Chief Executive Professor Icarus Allen said: “A statistic I find quite shocking is that, to date, humans have explored less than 5% of the world’s oceans. And yet, the ocean does so much for us. It’s absorbed at least 25% of carbon
Sulmara on Offshore Survey Job at Bayou Bend CCS Scheme in Texas
project in the United States, being developed by joint venture owned by Chevron, Talos Energy and Equinor.Bayou Bend CCS joint venture commissioned Sulmara to conduct an archaeological and geohazard assessment of the proposed Bayou Bend pipeline route from the landfall to the future offshore platform locations, which has the potential to reduce emissions from regional industrial facilities by safely storing carbon dioxide underground.Sulmara utilised an electric WAM-V 16 USV for the offshore data acquisition. The collaborative project also utilized the SpaceX-backed Starlink satellite system to ensure
