Buoyant cable and flowline protection Trelleborg’s offshore operation has launched Buoyant Uraduct ® , a protection system for subsea cables, umbilicals, flowlines and hoses. minimises drag and lift, avoiding possible stability issues.

cable so that it will not crush other lines at crossing locations.” Buoyant Uraduct can be customised to suit customer specifications for buoyancy, pipeline diameter and multiple subsea configurations. It is also an alternative to subsea crossing bridges, and can be installed on the cable or pipeline before it is laid on the seabed. As part of the Trelleborg offshore and construction business area of Trelleborg Group, Trelleborg’s offshore operation specialises in the development and production of polymer and syntactic foam-based seismic, marine, buoyancy, cable protection and thermal insulation products, as well as rubber-based passive and active fire protection solutions for the offshore industry. Within its portfolio are brands that include CRP, OCP, Viking and Emerson & Cuming. Trelleborg AB – Sweden www.trelleborg.com

Robert Knowles, design engineer with Trelleborg’s offshore operation, stated, “As the global requirement for data and product transfer increases, so does the demand for advanced cable and flowline protection. “When these vital lines cross each other on the seafloor, there is a potential risk of damage to the previously laid power cables or flowlines. “To create peace of mind in this situation, we took a look at how we could update our renowned Uraduct protection system to help reduce this risk. The solution we came up with was a buoyant protection system which would not

Based on the original Uraduct design, Buoyant Uraduct protects cables from abrasion and impact. The protection system reduces the crush risk at crossing locations by reducing the overall weight of a sub- sea cable. Made from highly buoyant materials, the protection system also
