JA Moody’s Post

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.

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

When a naval ship is docked for routine maintenance, equipment must be provided with a water supply. These water supply lines are exposed to the elements and are in danger of freezing during cold weather. ThermOmegaTech thermostatic freeze protection valves are installed on the supply lines at the dock to automatically bleed off the cold water and allow warmer water to backfill to prevent the pipes from freezing. https://ow.ly/lyZo50Qx7jk #freezeprotection #valves #water

While the maintenance practices will be speculated on & much hand wringing made over VIRGINIA & SSN-AUKUS timetables, can I suggest there is a bigger issue here. For Government, the ADF provides 3 things: Subs, SF & Australia's Federation Guard. Subs are the deterrent, SF are the kinetic action & Fed Guard is the soft force. For the 2 MPs who told me this, from opposite sides of the chamber & both help Ministerial Appointments of various kinds, the rest is nice to have but it's not as important as it thinks it is. So the big issue: Who is leaking about subs? Why are they leaking about subs? Why aren't they in gaol? The next bigger issue: Are we ready to manage VIRGINIAs?

A cruiser by any other name is just as expensive: What we are seeing is classification creep to make ships appear less expensive to the uninformed. The Constellation class frigate was sold as an upgrade to the LCS when in reality it is a slightly cheaper destroyer and as they are brought into service while Burkes are retired, they will be effectively be a downgrade from our current DDG’s. Likewise DDG(X), with a expected displacement of 13,500 tons is more appropriately called a cruiser.

For the United States Air Force, mission readiness matters. It matters as a function of high-level strategy, but also down to the seemingly small details—including the coatings protecting structural steel on bases throughout the world. That’s part of the reason why the specifications that guide coating product selection are as detailed and prescriptive as they are. But what if you know that a certain coating system will perform just as well—if not better than—those that meet the letter of strict government standards? And what if that certain coating system had the potential to end a trend of costly coating failures on military posts in humid coastal climates? Champion Specialty Services Corp. had the gameplan: demonstrate how an alternative system consisting of Carboline products would meet or exceed performance requirements in this environment, and then make the case that approving a variance from the current standard would be in the Air Force’s advantage. Read the case study to see how that went—and what it means for the future: https://lnkd.in/gyZHSTXc 

Minimizing return signatures of naval vessels. Hardened metallic and angular hulls. Would dissipating a mist or creating some type of radar-defying "water blanket" over a vessel be more effective than configuration (infrastructure) modifications? Material over infrastructure configuration
