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.

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

Want to save the U.S. Navy? Start by recapitalizing the Navy's small craft fleet. Nobody pays attention to this, but the Navy's small craft fleet is largely decrepit. And they do a lot--they prime new shipyards, give young mariners opportunities, bulk up maritime economies...heck, the small craft fleet of fifty-year-old crane barges and tugs is what'll break open the largest port blockade in modern U.S. History. Let's start flowing serious money into all those little ships--#tugboats #barges #workboats--we so often ignore. #USN #Navy #KeyBridge #Baltimore #harbor #maritime #shipbuilding #shiprepair #salvage #cargo #transport

Did you know that the first recorded use of a conveyor belt dates back to the late 18th century? It was used in a British naval dockyard to move large amounts of grain. Today, conveyor belts are a cornerstone of modern material handling, enabling efficient movement of goods in various industries. #funfactfriday #abercol #materialhandling

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?

If our government would put out steady consistent funding the industry can ramp up to support the work. We have been working off continuing resolutions for years. Continuing resolutions have a significant impact on US Navy ship repair and shipbuilding efforts. These resolutions, which temporarily fund the government agencies at the previous year's levels when Congress fails to pass regular appropriations bills, create uncertainty and disrupt long-term planning for the Navy, Ship Builders and Ship repair yards.

A US Navy review uncovers major shipbuilding delays, posing risks to readiness and underscoring design, workforce, and supply chain challenges. #Navy #ShipbuildingReview #Delays https://lnkd.in/g_YtDhrE

HII launches Amphibious Transport Dock Harrisburg (LPD 30) HII’s Ingalls Shipbuilding division successfully launched on Saturday the first LPD Flight II, San Antonio-class amphibious transport dock ship Harrisburg (LPD 30), marking one of the first major milestones in the ship’s journey towards operational readiness. The Ingalls team translated Harrisburg from land to the company’s floating dry dock using translation railcars to support the ship’s movement across the pier. While in the dry dock, the Ingalls team completed final prep work needed for launch. “We view this launch as a significant step toward fielding capability to our U.S. Navy and Marine Corps partners, and a reminder of the importance of supporting national security, as shipbuilders, we are dedicated to this mission.” Ingalls Shipbuilding President Kari Wilkinson The launch of LPD 30 follows the recent announcement of the amphibious multi-ship procurement contract for the construction of three San Antonio-class (LPD 17) amphibious ships [LPD 33-35] and a contract modification for the next America-class (LHA 6) large-deck amphibious ship [LHA 10]. Ingalls currently has two Flight II LPDs under construction including Harrisburg (LPD 30) and Pittsburgh (LPD 31). Pre-construction activities are currently underway for the construction of Philadelphia (LPD 32), the 16th ship in the San Antonio-class.
