Launching New Materials at Oceanology International North America - Microspheres & ROV Buoyancy - Trelleborg Offshore

Umbilical buoyancy is used in conjunction with ROVs to keep the required length of umbilical buoyant underwater.

Trelleborg Launches New Materials at Oceanology International North America

Trelleborg’s applied technologies operation will be launching its new innovative Eccofloat® TG30 and TG32 materials, at Oceanology International in San Diego, California in the U.S., on stand A16. 

Trelleborg’s applied technologies operation manufactures various grades of syntactic foams, called Eccofloat®, to meet customer requirements for deep-sea buoyancy applications. While at the show, attendees will be able to have a firsthand look at the new Eccofloat® TG30 and TG32 materials which have depth ratings of 5,000 and 6,000 meters respectively.

Bob Kelly, Managing Director within Trelleborg’s applied technologies operation, says: “One of the greatest challenges with manufacturing deep water syntactic foam is producing the lightest possible foam for a given depth. This translates into maximum uplift or buoyancy for the vehicle, which is what our customers are ultimately looking for.

“Our newest materials in our Eccofloat line are formulated with a high strength to weight ratio providing the maximum uplift or buoyancy per cubic foot. Eccofloat TG30 is rated for a depth of 5,000 meters and Eccofloat TG32 is rated for a depth of 6,000 meters. The uplift combined with the depth rating allows the customer the ability to design their vehicle with a lower volume buoyancy package, reducing costs and improving vehicle performance and handling.

“This is important because oceanographers depend on syntactic foams to suspend instrumentation in deep ocean studies. For these applications, the syntactic foam is used in either block form or custom molded shapes for installation in manned and unmanned submersibles such as the legendary Alvin and Jason vehicles that were used to discover and explore the Titanic.”

These two new materials complete our Eccofloat® range of materials which go from 1,000 meters to full ocean depth allowing customers to select the most appropriate material for their application and depth needs.

Eccofloat® syntactic foam provides superior uplift for given depths and has a proven track record to provide maximum years of reliable service.  The superior performance is achieved through the use of Trelleborg’s Eccospheres®, hollow glass microspheres, which are manufactured at the Trelleborg’s Boston, Massachusetts, facility.  The ability to custom manufacture and test this critical component of syntactic foam allows Trelleborg to produce industry leading strength to weight ratio materials.
