ATL bladder tanks are made from a variety of materials ranging from thin, flexible films to high strength fabric reinforced rubber. These bladders, inflatables and bellows boast unparalleled chemical tolerance, abrasion resistance and remarkable durability for long term storage. ATL recognizes the challenges that the harsh subsea environment presents and has developed materials and technologies that perform flawlessly in the extreme pressure depths of the sea. |

From the initial concept, ATL design engineers work with the client and utilize the latest in CAD technology to digitally construct your bladder to the exact specifications required. ATL's engineers use cutting-edge techniques to produce these flexible devices. Fabrication techniques include RF (Radio Frequency) sealing as well as thermal, friction, ultrasonic, vulcanization and adhesive welding. These methods yeild a super-strong and leak-tight bladder.
ATL also offers a wide variety of standard hardware, including fittings, valves, flanges and caps that can allow for easy fill/discharge/refill. If you are looking for totally custom hardware, ATL's factory is equipped with CNC capabilities that can handle jobs both big and small.
Some examples of ATL's subsea flexible bladder applications include bladders for liquid fuels and oxidizers, blow out prevention skid (BOP) bladders, methanol and ethylene glycol bladders, Monoethylene glycol (MEG) bladders, dispersant reservoirs, bladders for hydraulic fluids, flotation chambers, submersible ballast bladders, propane bladders, fuel bladders, lift bags, spill clean-up bags, pressure compensators, buoyancy bladders, dampers, accumulators, diaphragms and storage for chemical and cleaning solutions. |

ATL can assist with even the smallest of projects, like this bellows used for silicone oil in UUVs. |
Hundreds of unmanned underwater vehicles, torpedoes, submersibles, remotely piloted probes, mine detectors, towed seismic platforms, sonar buoys and sub-surface maritime weapons rely upon ATL's flexible fluid containers.
ATL's subsea flexible bladders are put to the test everyday in the most demanding underwater oil and gas projects:
Subsea Remote Intervention Systems:
-
Flexible Bladders for ROV (Remotely Operated Vehicles), AUV (Autonomous Underwater Vehicles) and Unmanned Underwater Vehicles (UUVs) for use with reactants (including caustic and acidic solutions and Otto Fuel), seawater, oxidizers, etc. in propulsion systems. ATL also designs and manufactures bladders for submersibles, subsea robotics and buoy/generator modules.
-
Leak-tight electronic enclosures, including battery boxes and instrumentation covers.
- Deep sea reservoirs and custom bladders in support of SURF
(Subsea Umbilicals, Risers, & Flowlines
)
- Control Fluid Test Bladders for Blowout Prevention Skids (BOP Bladders). These flexible BOP Intervention Skid bladders are used for function testing and accumlator charging and can either be ROV mounted or in cages on the bottom of the ocean floor.

This BOP (Blowout Prevention)
Intervention Skid, located on the ocean floor, features an ATL flexible bladder for fluid storage used during function testing and accumulator charging. |
Pipeline Services/Maintenance:
-
Flexible Bladders for storing Cleaning & Treatment Chemicals, some of which include - corrosion inhibitors, oxygen scavengers, biocides and dyes, which then are injected into pipelines during pre-commissioning operations.
-
ATL Bladders are also utilized in Oil Flushing operations, where systems such as fuel lines, lube lines, oil transfer lines and hydraulic systems are cleaned using various chemical cocktails.
ATL is proud to have worked for decades with organizations such as Woods Hole Oceanographic Institute, Scripps Institute, Oceaneering, Oceanworks, Weatherford, Lockheed-Martin, Halliburton, Trident, Perry Slingsby Systems, NSWC (Naval Surface Warfare Combatant Craft) and many others in exciting maritime programs.
