insertion issue, alongside a one-off launch/retrieval test can, designed to insert and retrieve the tool, ensuring containment for nitrogen testing. The isolation tool was to be inserted vertically down through various valves and a concentric reducer, and seated in a pre-determined position approximately 10m inside the riser line. The tool would then be energised to provide a complete isolation of the line, allowing for the removal/replacement of the 2"ns wrap around pipework. To ensure the valve seats were not damaged, the tool was supplied with iNPIPE bumper noses. The proposed solution, including the fabrication of a specialist isolation launch can, was designed and manu- factured at the purpose-built company production facilities within ten weeks. After full factory approval testing (FAT), the offshore installation was undertaken by the iNPIPE Products™ team.

to operate. iNPIPE has ensured that its Internal Weld Testers and Flange Weld Testers are effective to use. The solution also includes patented Posi-Seal technology, which ensures maximum seal for optimum testing results. Isolation tools and pipeline plugs have been developed with the same attention to the detail, offering optimum sealing qualities with the Posi-Seal technology used as standard. The Dual Tool offers a solution that can be used for both testing and isolation. iNPIPE Products was approached by Petrofac with a view to isolating a 24"ns export riser pipeline while rectification/ replacement work took place on a gas production platform off Great Yarmouth, UK. The integrity of the existing valve and the connection of the flange on the weldolet was in question, and it was impossible to insert a plug through the 2"ns valve to facilitate removal or replacement. After an initial site survey by an IPP technician, a triple tyred isolation tool was designed to overcome the

the company’s ambitious plans. The location is strategic, as the city of Lom is a major Danube port and transportation hub, which could turn the factory into a key point for the European steel supply chain along the river. In 2013 HUS acquired steel distributor Metalsnab Bulgaria, previously owned by Kloeckner Metals Corporation, extending its domestic network of warehouses and steel centres.
