As stocks of natural resources near depletion and extraction facilities approach termination, the process of removing off shore facilities has gathered pace and is set to intensify even further in the next decade.

The considerate decommissioning of redundant assets within the gas, petrochemical, pharmaceutical and power generation industry sectors plays a significant part in their future and lays the foundation of a sustainable approach to the development of medicines, vaccines, greener energy and products that will be required by future generations. We possess the in-house technical knowledge and management experience to successfully deliver extensive and complicated decommissioning projects. Our experience and proven track record enables us to choose the precise methods to address any complexities which may be encountered.

CASE STUDY Client: Boots PLC Programme: 6 weeks BOOTS, NOTTINGAM Value: 75k Boots Beeston is the administration and warehouse storage facility for one of the biggest retailers in the UK and Ireland. Due to the advancements in automated packaging, large sections of the warehouses were internally ‘demolished’ and stripped back to the original structural shell to enable the buildings to be re-purposed to accommodate the insulation of state- of-the-art packaging and sorting equipment. Project constraints & challenges included: • Works carried out on a live facility working 24/7 • Specialist demolition rigs were procured for the works • Existing floor slab and superstructure had to be maintained for re-use • Working around live service • Material segregation and waste streaming • M aintaining a clean environment throughout the works and adjacent areas.

CASE STUDY Client: St Francis Group Programme: ? BRITISH SUGAR, KIDDERMINSTER Value: £1.2m The client purchased the former 74 acre sugar beet factory from British Sugar to convert the site into a mixed use site comprising of employment land,residential, retail, a leisure centre and care home. The client commissioned DSM to demolish the production and storage facility which included the decommissioning of an integrated power station, molasses tanks and silos which were in excess of 70m high and the site contained open areas of concrete beet troughs and factory soil settlement ponds. The previous use of the site had deposited significant quantities of oil into the ground and with the agreement of the Environment Agency a mechanical oil interceptor system was set up and maintained to prevent oil spilling on to the adjacent mud flast which were SSSI and RAMSAR. Principal Constraints and considerations: • Decommissioning of specialist equipment • R emoval of hazardous materials including extensive asbestos removal and waste • Demolition of redundant structures which posed health and safety risks. • Extensive remediation strategy which was developed in conjunction with the Environmental Health Officer and the Environment Agency. • Japanese knotweed located on site.

CASE STUDY Client: TATA Steel Programme: 15 weeks COKE OVENS, PORT TALBOT Value: £ 500k DSM were appointed as specialist demolition contractor to remove an 85 high by 51 meter diameter shell structure which had been stiffened with rings along its height and vertical columns around its perimeter. The structure took its strength from the ring effect formed by the shell body. Following a structural assessment an opening was formed in the shell to enable explosives to be placed within the structure. DSM were asked to undertake a feasibility study prior to award of contract and advise the most suitable option. The decision was taken on the basis that: • The method would minimise working at height • Minimal pre-weakening (weather conditions) • W orks could be delivered in a sterile exclusion zone • Certainty of collapse • Material processed early and removed at ground level.

CASE STUDY Client: St. Modwen Developments Programme: ? MG ROVER, LONGBRIDGE Value: £ 450k Asbestos removal and demolition of the former MG Rover Group Estate’s, west works manufacturing facility in Birmingham. DSM were appointed as Principal Contractor to undertake the asbestos removal and demolition of the former MG Rover Group Estate’s, west works manufacturing facility in Birmingham. The works involved the removal of asbestos containing materials, and demolition of 65,000 sq. m of industrial heavy duty plant, including the safe removal of a conveyor which spanned the A38 dual carriageway, two track railway and car parking area which was situated between the old west works and north works car plant. The conveyor was built to transport car bodies from the paint shop to the west works assembly hall. The demolition of the former MG Rover Group Estate’s, west works manufacturing facility in Birmingham.

CASE STUDY Client: Aberdeen Gas Holder Programme: 36 weeks ABERDEEN GAS Value: £ 558k The gas holder at Aberdeen was a 55m in diameter above ground gas holder which was constructed in 1958. The works involved the decommissioning, demolition and re-mediation of the 2 hectare site. Phase I - involved the submission of appropriate statutory notifications and included the termination of remaining (non gas) services, removal and discharge of water within the holder to a foul sewer. Prior to commencement of the second phase of the works, environmental monitoring was undertake to pre-determine levels. Once these had been agreed works commenced on the second phase and these involved cutting of the 30% of the gas holder crown, in order to form an opening, cold cutting of the internal skins, de-sludging and removal of residual waste, as well as soft stripping the surround buildings. The final phase of the works involved the appointment of an external re-mediation consultant to test the stockpiled materials prior to any remediation works taking place.

CASE STUDY Client: St Francis Group Programme: 3 years EGGBOROUGH POWER STATION Value: £ 30m The works comprised of the drawing down and decontaminating the former Turbine Hall, Boiler House, Bunker Bays, Generator Building, Conveyors and Ancillary Buildings and former Coal Yard. Other works on the 80-acre power plant site included the removal and disposal of substantial residual chemicals and extensive areas of licensed asbestos containing materials. Constraints & challenges: • L arge scale scaffolding was required to assist operatives undertaking complex operations at height of up to 120ft • Logistics planning to coordinate the multi-discipline trades on site • Welfare and working systems to comply with Government and NHS Covid-19 protection measures • Employment of an additional 80-90 operatives to enable us to deliver the works safely and to our client’s programme • P rocuring plant and materials during a period of industry shortages (directly caused by Covid-19).

DSM’s to Landfill”, existing 5-year Plan is in place for the period 2020 – 2025 and sets out a targeted mean annual and participate reduction of 5% CO2e. in the National Industry Symbiosis Five-year carbon reduction plan Programme and Sustainability Considerable investment during 2020 - 2021 into replacement of existing D-Rig plant and School. equipment ranging from 1tn to 55tn. Changing from existing manufacturer to Kobelco offering enhanced engine efficiency and reduced emissions. Further investment in 2021 – 2022 to replace existing plant ranging from 67tn to 85tn. Changing from existing manufacturer to Kobelco offering enhanced engine efficiency and reduced emissions. Introduction of hybrid 20tn – 22tn machines for use in crushing / other operations where significant slewing is required. Investigation into carbon offsetting underway for hydrocarbon energy sources that cannot be eliminated. Commitment to switch to low emission HVO fuel Commitment to switch to low emission HVO fuel for site and vehicle use. Typical bio-diesel blend providing a 93% CO2e kg per litre reduction on conventional bio-blend fuels. By far the most significant source of carbon emissions within DSM is the use of hydrocarbon fuels for plant and transport. Whilst being a strong advocate of adopting technological advancement in plant and equipment as and when they present, DSM has recognised that in order to achieve significant and immediate reduction in carbon emissions the use of alternative fuels to traditional diesel products needs to be adopted.
