Onshore Decommissioning


Oil & Gas structures that have reached the end of their operational life must be safely decommissioned, dismantled and recycled in the most environmentally friendly manner. Thompsons of Prudhoe have an incredible and rich history dating back to 1948, with a wealth of experience when it comes to providing decommissioning solutions.


Thompsons of Prudhoe have established a partnership with the Port of Blyth to create a safe and effective onshore dismantling and waste disposal decommissioning operation and services.


In accordance with the Thompsons’ policy, we shall endeavour to recycle as much of the materials that arise from our services as possible, often achieving in excess of 97%+. Our commitment to this can be demonstrated through our Integrated Management System, certified to ISO 14001 (Environment) and ISO 50001 (Energy).


Our 2.3 Hectare site at Battleship Wharf Terminal is available for all onshore decommissioning projects. The site includes impermeable surfaces, interceptors, water recycling, bunded quarantine areas and covered storage and is situated 100m from berth 4 with a 50m wide access route from the quay to the set-down area.

Assets and Subsea Materials

Thompsons of Prudhoe can provide assets for onshore decommissioning of offshore oil and gas installations as well other oil and gas equipment for both onshore and offshore use such as topsides, jackets and structures.

Onsite NORM Treatment Facility

This state-of-the-art Naturally Occurring Radioactive Material (NORM) facility, located at our site in the Port of Blyth, provides an onshore turnkey solution and high quality decommissioning programme to our customers based in oil and gas facilities across and in the North Sea.

At our NORM facility in Blyth, offshore oil and gas materials don’t need to be sent off for cleaning as they can be done onsite at our onshore facility. This geographical and industrial strategy removes the need for materials to be transported to other facilities across the country, which both saves transportation & decommissioning costs for customers and reduces our carbon emission levels.

Operational Support

The Port of Blyth specialises in project cargo handling and movement for the offshore energy sector. Thompsons of Prudhoe have full engineering and operational support for landing and moving equipment/pieces including lift/movement plans There is port cranage of up to 100 tonne lift capacity readily available on site for work on the quayside or the decommissioning site. There is also heavy lift cranage of up to 500-tonne lift capacity – available on site from heavy-lift partners.

  •  Topsides & jackets to be landed to Berth 4 and moved 100m to decommissioning site for safe disposal.
  • Extensive supply chain exists within the Port for full mob / demob operations on project vessels.
  • Up to 2,000-tonne project pieces moved through Port terminals using SPMTs
  • Regular 250 tonnes + project lifts undertaken utilising super lift cranes and SPMTs.
  • Reputation for first-class support of offshore energy related vessels and project movements

Thanks to our partnership with the Port of Blyth, Thompsons of Prudhoe are proud to be strategically placed on the east coast of the UK, midway between Aberdeen and Great Yarmouth. This industrial strategy means that we are well placed for decommissioning assets from the Northern, Central and Southern North Sea sectors, allowing us to maximise the number of decommissioning programmes we can carry out.


There are also substantial, uncongested road links to the Port – with Newcastle International Airport only a short 20 minute drive away.

Strategic Partnership


Thompsons of Prudhoe are proud to have formed a partnership with the Port of Blyth that will enhance the UK onshore decommissioning capability.

A joint investment of up to £1m will be used to enhance and develop the existing facilities to create an initial 1-hectare decommissioning site with further development opportunities increasing to 2.3 hectares.

Expansion works are commencing immediately with the existing facility remaining open for business throughout.
