Processing and recycling flexible risers and flowlines
Project Summary

Many miles of flexible flowlines, risers and umbilicals play an important role in oil and gas production in the North Sea. During field decommissioning programmes these items need recovered and brought ashore.

Over the past decade, John Lawrie Group has brought ashore thousands of tonnes of flexible flowlines, risers and umbilicals at ports across Scotland. It has successfully developed processing methods that result in high recovery and recycling rates of the metallic and non-metallic content.

The predominately mechanical recycling process involves separating the various metallic and non-metallic layers of the flowlines and umbilicals. Each layer is systematically removed and the component parts sorted for recycling.

Plastic materials are transferred to authorised recycling contractors for further processing before being made into new products. The separated metal content is processed at one of John Lawrie Group’s metal recycling facilities to ESSS standard, before being exported to European steel mills for recycling into new steel products, delivering significant environmental benefits.
