Engineered Syntactic Systems (ESS), a global supplier of syntactic solutions, has provided Bluefin Robotics with syntactic buoyancy systems for their family of AUVs, including the 4500-metre Artemis 21 used in the ongoing search for missing Malaysia Airlines’ Flight 370.
The Bluefin 21 was designed for extended remote operations in the hostile conditions of the deep sea. At just 21 inches in diameter, space for uplift (buoyancy) is limited, but critical. ESS worked closely with Bluefin to engineer a buoyancy solution that would meet their design specifications, providing a syntactic material with the lowest density available for that depth, thereby the most lift.
“The folks at Bluefin came to us looking for a buoyancy package that could go to 4500 meters and still fulfill their stringent density requirements. We worked closely with them to develop a product that would meet their needs,” says Thomas Murray, managing partner at Engineered Syntactic Systems.
The unique capabilities of ESS’ high-performance syntactics allow manned and unmanned vehicles like the Bluefin 21 AUV to operate for long periods of time at the deepest ocean depths. ESS syntactic materials deliver high hydrostatic strength and the best buoyancy-to-depth ratio available today.
“ESS has extensive knowledge in the area of syntactic materials,” said Harry Stants, Director of Manufacturing and Supply Chain at Bluefin Robotics. “We trusted them to develop a buoyancy system that would keep the overall vehicle weight low – but was durable enough to take the pressure of the operational depth.”
With the world watching, it was in part the confidence in ESS’ buoyancy system that helped Bluefin and the vehicle operations team assess the overall operational risks and successfully take the AUV deeper than its design depth during the search.
