Skelmersdale, UK -- Trelleborg Offshore has recently been working on a contract to supply underwater equipment manufacturer Soil Machine Dynamics Ltd (SMD) of Wallsend, UK, with high-performance syntactic foam buoyancy modules.
The modules will be used on 20 new-build work-class remotely operated vehicles (WROVs) by SMD, which has delivered 17 of these vehicles. Work is continuing on an additional nine vehicles, said Trelleborg Offshore.
Trelleborg says it field-proven modules are being used by SMD on its 'QX Ultra' brand WROVs, manufactured for i-Tech (a division of Subsea 7). This business operates one of the world's largest ROV fleets dedicated to the offshore exploration and production industry.
The new WROVs will be deployed for subsea use at oil and gas fields offshore from Brazil.
According to Skelmersdale, UK-based Trelleborg Offshore, the buoyancy modules are specified to work at depths ranging from 1500-3000 MSW (metres of sea water) and consist of a composite composite syntactic foam core coated in polyurethane. 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.
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 says its syntactic foam was developed to ensure the optimum strength to weight ratio for ROV operators. The material offers safer operations through increased uplift, stability and buoyancy.
Guy Downie, sales manager with 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 30 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."
Trelleborg said that 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.
