APV Heads Works With James Cameron


Hollywood Director James Cameron Partners With APV Heads

At APV Heads, we’re proud to have been a part of some amazing projects in our 75+ years of manufacturing pressure vessel heads. But did you know we also worked with Hollywood royalty? Esteemed Titanic director James Cameron enlisted the help of APV Heads in 2012 to build the 109cm case of the Pilot’s Chamber for a bright green submersible known as the “Deepsea Challenger”.

Built in Sydney and with APV Heads’ assistance, he was able to dive to the lowest known point of the earth at 10,900 metres below the ocean’s surface, located at the Marianas Trench. At this depth, the pressure is 1,000 times that of the surface, so only the highest quality components would do. At last count, Cameron has made 33 dives to the Titanic wreckage, as well as other deep sea explorations, and APV Heads are proud to be part of his amazing feats.

Beyond James Cameron’s submersible, pressure vessel heads are heavily relied upon by the Navy. These components play a crucial role in ensuring the safety, performance, and operational capabilities of various naval vessels.

How the Navy Uses Pressure Vessel Heads

As vessels that require the utmost in quality, performance, and reliability, it makes sense that the Navy relies on APV Heads for their manufacture. Thanks to their ability to withstand high pressures and strengthen the structural integrity of naval vessels, pressure vessel heads have many uses.

By examining their current applications in the navy, you can see just how versatile a pressure vessel head can be.

  • Pressure Hulls: Pressure vessel heads are essential components of submarines’ pressure hulls. These heads are designed to withstand the tremendous external pressure encountered at deep-sea depths, ensuring the structural integrity of the submarine and the safety of its crew.
  • Steam Generators and Boilers: Naval vessels, including aircraft carriers and cruisers, often rely on steam propulsion systems. Pressure vessel heads are utilised in steam generators and boilers to contain high-pressure steam, which is then used for powering the ship’s engines and other onboard systems.
  • Auxiliary Systems: Pressure vessel heads are incorporated into various auxiliary systems onboard naval vessels. These systems include compressed air tanks, hydraulic reservoirs, and other pressurised storage containers used for critical operations, such as weapon systems, machinery control, and emergency power.
  • Fuel Storage Tanks: Naval vessels require substantial fuel storage for extended missions at sea. Pressure vessel heads are used in fuel storage tanks to ensure the containment and safety of large volumes of fuel. These heads help prevent fuel leakage, maintain fuel quality, and provide structural integrity to the tanks.
  • Pressurised Fluid Systems: Pressure vessel heads are utilised in pressurised fluid systems throughout naval vessels. These systems may include hydraulic systems, pneumatic systems, and other pressurised fluid circuits that are critical for ship operations, such as steering mechanisms, weapon systems, and launching systems.
  • Desalination Plants: Many naval vessels, particularly those deployed for long periods at sea, feature desalination plants for producing freshwater from seawater. Pressure vessel heads are used in the high-pressure pumps and reverse osmosis systems involved in the desalination process, ensuring efficient water production.
