What Are Wave-Induced Ship Motions? When ships move through the ocean, they are affected by waves, which cause them to move in different ways. These movements are called wave-induced ship motions and they can affect how stable, safe, and comfortable a ship is. There are six main types of motion that ships experience: 1. Surge – moving forward and backward 2. Sway – moving side to side 3. Heave – moving up and down 4. Roll – tilting from side to side 5. Pitch – the front and back moving up and down 6. Yaw – twisting or turning around These motions can have a big impact on ship operations. For example, too much rolling can make it unsafe for the crew, and heaving can make it harder for the ship to move through rough seas. By understanding and managing these motions, we can design better ships and improve safety at sea. This is especially important for industries like shipping, oil & gas, and naval defense. #MarineEngineering #ShipDesign #WaveMotion #SafetyAtSea

“Only a sailor knows the true depth of the ocean's challenges.” Netzer products are integral to several marine environment applications that demand rigorous environmental and shock performance. In the harsh sea, solutions must withstand significant blows and shocks. Netzer encoders, with their capacitive technology, are uniquely suited for these scenarios. Their ability to provide an absolute position even without movement is critical for naval applications. Additionally, the low-profile and hollow-shaft design ensures a streamlined, neat look with absolute accuracy and performance. Contact us to discuss your naval motion requirements and discover how Netzer can enhance your naval solutions. #NetzerPrecision #AbsoluteRotaryEncoders #PrecisionEngineering #AdvancedTechnology #MarineLife #Encoders #harshenvironment #MarineTechnology #NavalSolutions https://lnkd.in/dZdsUfq

The US Navy’s 25th Virginia-class submarine is launched by HII HII announced that Virginia-class submarine Massachusetts (SSN 798) was recently launched into the James River at the company’s Newport News Shipbuilding (NNS) division. Shipbuilders transferred the submarine from a construction facility to the floating dry dock, where it was later submerged and moved by tugboats to a submarine pier at the shipyard for final outfitting, testing and crew certification. “Following the christening of this mighty submarine in May, witnessing Massachusetts launch into the river is a source of immense pride for our shipbuilding team, we understand the importance of Massachusetts, and we will continue to execute with purpose to bring this important national security asset to life and deliver it to the Navy.” Jason Ward, NNS vice president of Virginia-class submarine construction Virginia-class nuclear-powered fast attack submarines are built for a broad spectrum of open-ocean and littoral missions to replace the Navy’s Los Angeles-class submarines as they are retired. Virginia-class submarines incorporate dozens of new technologies and innovations that increase firepower, maneuverability and stealth to significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at speeds of more than 25 knots.Massachusetts is the 25th Virginia-class submarine and will be the 12th delivered by NNS, which is one of only two shipyards capable of designing and building nuclear-powered submarines for the U.S. Navy.

A fire main system aboard any US Navy vessel distributes pressurized seawater for firefighting, auxiliary equipment cooling, dewatering, and wash down services. The fire main is one of the most mission critical fluid distribution system aboard any Naval vessel. It follows then, that the isolation valves in such a critical system would be designed to enable the crew’s ability to quickly isolate portions of the fire main after battle damage. Emerson’s TOTS (triple offset torque seated) valve (Vanessa) does this very well. The Vanessa valve has the double offset features of The Navy’s standard High- Performance Butterfly Valve (MIL-V-24624), but a third offset was created. Offset 3 is where the seat and seal cone centerlines are inclined in respect to the pipe/valve centerline. This third offset eliminates rubbing completely, yet still results in zero leakage. These features support a longer life expectancy, reduced maintenance requirements, and a lower cost of ownership compared to traditional gate, butterfly, and other valve designs. In general, the Vanessa valve will usually fit perfectly into the space vacated by an older-style butterfly valve. Contact that JA Moody technical sales team for more information and pricing. #Shipbuilding #MarineIndustry #Valves #Actuators

curious about more details on our recent navy demo? check out the blog post
We recently had the honor of participating in the US Navy Advanced Naval Technology Exercise (ANTX) as part of their Coastal Trident Program - and it went swimmingly! Across nearly two weeks of surveying we successfully mapped targets including an outfall pipe, a sunken plane, barge and tugboat, a piling and various objects placed on the seafloor by the Navy. Read more about our time in San Diego & check out some of the data we collected while we were down there: https://lnkd.in/gU8qaWgy

#Baltimore #bridge #collapse shows the #vulnerability of #supplychains. One bridge collapse has shut down the entire harbor’s logistics and transportation capabilities. IMHO, the author’s argument linking it with sabotage, cyberattack, or hijacking is way too far. However, I agree that the single propeller and single rudder on the container ship are critical factor for the collapse. I don’t know how many backup systems a commercial ship has. For a naval ship, she has at least two propellers and five backup rudder systems to ensure the survivability. I don’t except that commercial ship will adopt many redundant systems as naval ships. However, she should have at least two redundant systems not to repeat a similar accident in the future. https://lnkd.in/g8GKgdmk
