In response to the increasing number of additional cables requiring access to and from offshore platforms, we have developed Uraduct® Retrofit Riser System which comprises of Uraduct® and dedicated, high integrity, locating clamps.
This system provides a very cost-effective solution where cable access to a platform is not possible via exisitng 'J' or 'I' tubes. Prior to our Uraduct® Retrofit Riser System, the only alternative was to install new steel 'J' or 'I' tubes at great expense, compounded by time consuming and problematic installation.
The introduction of the Uraduct® Retrofit Riser System, has led to substantial cost savings and improved installation times resulting in a number of projects coming to fruition which previously would not have been possible.
The securing clamps for this system are designed to withstand the extreme conditions experienced on offshore installations and can be configured to suit multiple cables. Under normal circumstances the clamps are pre-installed onto a suitable platform leg or structure at regular intervals, the spacing being dependent on the security required. Alternative clamp designs are available where multiple cables are to be installed. The clamp bodies are manufactured from a high performance, rigid, marine grade polyurethane elastomer. No special welding equipment is required as the clamp bases are secured by means of a Polyloop™ high strength Kevlar/EVA coated strap and a highly corrosion resistant metallic tensioning assembly, typically manufactured in Zeron 100 or Titanium.
Features
Our Uraduct® Retrofit Riser System has been successfully installed on platforms throughout the world, the number of installations is set to grow particularly considering the increased use of submarine fibre optic cables and inter platform power cables.
