At Veolia we are always striving to deliver innovative ways to turn waste into a resource for our customers throughout the UK. Click below for some examples of our great work in action.

Shell INDE

Shell operates a number of oil and gas assets in the North Sea. As the Shell Indefatigable (INDE) field came to the end of its useful life, its infrastructure had to be decommissioned in a safe and environmentally responsible way. The platforms consisted of eight gas field ‘jackets’ and eight topsides weighing a total of around 10,500 tonnes.

The Challenge

This was a true test of Veolia’s technical and industrial capability and required the right planning and engineering
procedures to be in place for the receipt and load-in of the vast structures. The key goals were to:

  • Load the structures from delivery barges to the quayside
  • Move to stillages in designated areas
  • Dismantle, recycle and dispose of materials in line with Environment Agency expectations

The Solution

Veolia has the know-how to achieve high recycling rates for end of life assets, so clients can profit from asset reuse and landfill savings, as well as meeting environmental targets.

The platforms were towed on barges 120 nautical miles from the INDE field by Seaway Heavy Lifting.

Detailed risk assessments for the load-in and set down of the structures were undertaken.

Veolia carried out a comprehensive inspection, sampling, decontaminating and safely removing waste streams using detailed method statements.

Once certified for deconstruction, the demolition phase began in line with detailed engineering plans. Cranes and excavators minimised the risk to manual labour as the structures were reduced in size.

The Results

16 load-in operations managed successfully

Materials carefully segregated and recorded to maximise recycling value

98.9% re-use and recycling rate

  • 10,500 tonnes recovered

Veolia was able to dispose of the entire structure in the most environmentally-friendly way. 98.9% of the materials were sent off site for recycling, maximising re-use and minimising landfill costs for Shell.

“Shell has set a 97% recycling target for the topsides – a figure we already achieved when decommissioning the structures at the Shell Indefatigable gas field in the North Sea.”
