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. ESS subsequently produced similar parts for the REMUS 6000 vehicle.

	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.
