Buoyancy supplied for ROVs

Trelleborg Offshore awarded contract to supply syntactic foam buoyancy modules for twenty new build work-class remotely operated vehicles (WROVs).  

Trelleborg Offshore was awarded a contract to supply underwater equipment manufacturer, SMD, with high-performance syntactic foam buoyancy modules for twenty new build work-class remotely operated vehicles (WROVs). SMD has delivered seventeen of these vehicles and work progresses on an additional nine vehicles.

Buoyancy for deep water
Trelleborg’s field proven modules are being used by SMD on its ‘QX Ultra’ WROVs manufactured for i-Tech (a division of Subsea 7), which operates one of the world’s largest ROV fleets dedicated to the offshore exploration and production industry. The WROVs will be deployed for subsea intervention activity at oil and gas fields offshore Brazil.

The buoyancy modules are specified to work at depths ranging from 1,500-3,000 MSW (meters sea water) and consist of a syntactic foam composite core coated in polyurethane (PU). To ensure the modules retain the required structural integrity in deepwater environments, a homogenous "hard shell" is incorporated into the outer layer of the PU elastomer skin.

Longstanding relationship
Mark Collins, ROVs Business Stream Manager at SMD, said: “We have a longstanding relationship with Trelleborg. The company’s industry knowledge, manufacturing quality and capacity to deliver made them an obvious choice for the contract. We were confident that Trelleborg would be able to meet the project specifications, to the highest of standards, and on time.”

Trelleborg’s syntactic foam was developed to ensure the optimum strength to weight ratio for ROV operators. The specialist material provides safer operations through increased uplift, stability and buoyancy.
Unrivalled track record
Guy Downie, Sales Manager, Trelleborg Offshore, said: “This contract enhances Trelleborg Offshore’s position as the industry’s leading manufacturer of buoyancy modules. We have an unrivalled track record with more than thirty years experience in the sector and our modules are installed on more than a thousand ROVs worldwide. Our expert material knowledge and extensive buoyancy product range means we can provide tailored solutions for every subsea environment.”

SMD is the world’s largest original equipment manufacturer of work-class and specialist ROVs. The company’s extensive underwater experience and knowledge have led to its rapid growth and its WROVs are now used on major projects across the globe.
