Trelleborg’s offshore operation has launched a protection system for subsea cables, umbilicals, flowlines and hoses. Based on the original Uraduct design, Buoyant Uraduct protects cables from abrasion and impact, reducing the crush risk at crossing locations by reducing the overall weight of a subsea cable — it also minimises drag and lift, avoiding possible stability issues.
“As the global requirement for data and product transfer increases, so does the demand for advanced cable and flowline protection," said Robert Knowles, Design Engineer with Trelleborg’s offshore operation. "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 Uraduct protection system to help reduce these risk. The solution we came up with was a buoyant protection system which would not only protect cables from abrasion and impact, it would also reduce the excess weight of a subsea cable so that it will not crush other lines at crossing locations."
Buoyant Uraduct is a protection system for subsea cables which can be customised to suite customer specifications for buoyancy, pipeline diameter and multiple subsea configurations. It is also a suitable alternative to subsea crossing bridges and can be installed on the cable or pipeline before it is laid on the seabed.
