Custom Syntactic Systems
Challenging applications often require a new engineering approach rather
than an off-the-shelf product to sufficiently meet the needs of the customer.
ESS has the design experience and ingenuity to satisfy even the most
unique requirements. The variability of the composite syntactic system
and its wide range of constituent properties allows for ESS to tailor the
final syntactic properties to those demands. We welcome the opportunity
to meet those challenges.

Recent Case Studies
Composite Syntactics for Autonomous Underwater Vehicles (AUVs)
In late 2006 ESS began working with Hydroid, Inc, (Wareham, MA, www.hydroidinc.com),
the manufacturer of the REMUS AUVs to supply subsea buoyancy packages for
its REMUS 600 and REMUS 6000 vehicles.  In early 2007 we delivered complete
buoyancy packages for the REMUS 600. The turnkey project included
production and hydrostatic proof testing of the BZ-24 syntactic,
coordination of the machining, fiberglass lay-up, painting and final
hydrostatic proof testing of each unit. Presently nearly 10 complete R600
buoyancy packages have been delivered.

ESS subsequently produced similar parts for the REMUS 6000
vehicle. In 2008 two complete buouyancy packages were created for the WAITT
REMUS 6000 vehicles. This project utilized AZ-34 syntactic and was
successfully tested to 9000 psi. The vehicles are now operational in the
South Pacific.

Submarine Void
Fills
In 2007, four different 688-Class submarines were outfitted with syntactic foam
systems by the ESS staff. All syntactic injections were performed on-site
by ESS technicians. Utilizing specially modified mixing and injection
equipment, our crews traveled to the shipyard and filled free-flood areas
and cavities with syntactic during standard DMP and SRA modifications. In
2008 two additional projects were completed. One project involved a
688Class sub, while the second was a syntactic fill on a Trident-Class
submarine.

Deep Submergence
Vehicle
Deep Flight Challenger was built by Hawkes Ocean Technology, (www.deepflight.com)
to enable adventurer, Steve Fossett, to set the ultimate solo dive record
for all time (37,000 feet). ESS manufactured and delivered a 45 lb/ft3 foam
tested to full ocean depth as the buoyancy package for Challenger.
Unfortunately Fossett perished in a plane crash before he could dive the
submersible to record depth.
