NOVACAVI Hybrid Umbilical Powers AI Robot in Dock Restoration
, has been chosen to design and manufacture a hybrid buoyant umbilical that will drive an AI-guided demolition robot during the rehabilitation of Dock 7 at the Port of Trieste.The arm-equipped robot will remove deteriorated concrete using high-pressure hydro-demolition while protecting the underlying steel structure. Reliable power, control and real-time data transmission will be delivered through NOVACAVI’s hybrid buoyant cable. Wrapped in a hydrolysis- and UV-resistant matt polyurethane (PUR) sheath, the cable combines lightness, buoyancy and rugged durability—ideal for demanding marine infrastruct
Optimizing Cathodic Protection Survey Using Non-contact Sensors
location, depth, environmental conditions, and the specific requirements of the maintenance plan.The most common form of measuring CP systems is known simply as ‘stabbing’. It involves the use of a contact probe (a.k.a., ‘CP stabber’) making direct contact measurement to the steel structure and the anodes, either by divers or ROVs. The probe typically consists of one or two silver/silver chloride (Ag/AgCL) reference electrodes. A voltmeter measures the potential difference between the structure and the reference electrode.The CP level of structures can be measured with conventional

Floating Wind Tech: TetraSpar Demonstrator Starts Operation Off Norway
test site, has been successfully connected to Norway’s grid and is producing power in automatic, unattended operation. It is located next to the old Hywind demo site that has been in operation since 2009.The TetraSpar foundation, owned by Shell, TEPCO RP, RWE, and Stiesdal, is a tubular steel structure with a suspended keel. The floating platform, including the 3.6-megawatt turbine, was towed from Denmark to the Norwegian METCentre earlier this year test site and installed in waters as deep as 200 meters. According to RWE, the power start-up marks the start of the test phase where data
Subsea 7 Takes Majority Stake in Floating Wind Tech Player
firm Subsea 7 on Monday revealed has reached a deal to acquire a majority interest in the equity of Nautilus Floating Solutions S.L., a Bilbao, Spain-based developer of technology for the floating wind market.Nautilus has developed a concept for a floating wind foundation based on a semi-submersible steel structure that supports a centrally-placed wind turbine. Subsea 7 said it will provide technical expertise, and engineering and project management capabilities, to support the advancement of this design, and it is envisaged that the concept will be included in tenders for demonstrator or pilot projects
