A new stackable version of Trelleborg Offshore’s RiserGuard® system was developed to provide a solution for rigs with limited storage space. The system allows stacking of mixed, dressed riser joints, while still offering the same protection as the original system.

The joints can be stacked alongside buoyant riser joints in the same deck storage area due to strategically placed protective sections spaced within the joints that accept and transfer loads between the joints and deck storage area.

Alan McBride, vice president of drilling, Trelleborg Offshore, explained, "We originally developed our RiserGuard product to help protect bare riser joints as they were handled and run on the rig. In addition, the product would enable the riser to be run and pulled quicker, saving valuable rig time.

Designed as a free-flooding, self-equalizing, neutrally buoyant unit, the Stackable RiserGuard offers complete protection for bare riser joints and external lines during handling, storage and drilling operations. The bare or slick riser joint system consists of a series of two piece half shells affixed to the outside of the riser joint.

More information on the Stackable RiserGuard is available.
