Case Studies - ROV

As a trusted partner of naval, subsea and oceanographic organizations, ESS has supplied products for some of the most exciting under-sea exploration projects in the last decade. Designed to meet the rigorous demands of undersea environments, ESS syntactics are a critical component for manned and unmanned exploration vehicles, plus a wide array of flotation and buoyancy applications.



SeaBotix LBV Recovers Remus AUV in 137 Meters of Water: A Hydroid Remus 600 (one of just two in operation at the time – valued at nearly $1 million) was lost. SeaBotix located and recovered the AUV within two days. SeaBotix Sealift and LBV950 mini ROVs utilize ESS BZ grade syntactic.


ROV Jason

Jason was first launched in 1988 and has been used for hundreds of dives in the Pacific, Atlantic and Indian Oceans. A sturdier, more advanced second generation Jason was launched in 2002. Over the last 8 years, ESS has provided buoyancy upgrades for Jason, including the addition of 500 lbs of 7000 meter syntactic in 2014.


Schilling ROV (#1)

48 Tons of Silver Recovered From 4,700 Meters; Heaviest, Deepest Haul Ever - In 2012, Odyssey Marine Exploration recovered a record-breaking haul of silver from the SS Gairsoppa, a British cargo ship sunk by a German torpedo during WWII. Odyssey used a Schilling HD 5000m ROV containing ESS syntactic foam.


Schilling ROV (#2)

Schilling Robotics utilizes ESS provided buoyancy packages for its 4K and 5K HD ROVs. The three-part buoyancy sets are precision machined, urethane coated and painted with a marine grade layer. Schilling generated animation shows a typical ROV in action.



Isis ROV (#1)

One of the deepest operating ROVs currently in service is Isis, operated by the UK’s National Oceanographic Center off of the RRS James Cook research ship. ESS refurbished and replaced the 7000 meter buoyancy package after damage to the original foam occurred in a 2011 propeller incident. Isis was successfully returned to service in 2013.


Isis ROV (#2)

Isis ROV Explores World’s Deepest Known Undersea Vents - The Isis ROV has reached the Cayman Trough’s Beebe Vent Field at a depth of ~5 km (3.1 miles). After it was damaged in 2011, ESS repaired the starboard side buoyancy and replaced the port side package with 30-lb/ft3 material rated for 7,000 meters.
