Technical Demolition Services Ltd has undertaken many tank demolition operations either as a specific contract for tank demolition only or as part of a contract for the demolition of large production plants such as chemical works, refineries, industrial sites, etc.

We have a vast experience in undertaking this work along with the methods involved in order to minimise any risk to the health and safety of both the TDS workforce and any localised workforce from the client or his partners.

In addition, certain methods may need to be considered in regards to all localised ‘live’ plant that is still in operation and the impact of the demolition plan within these areas.

Information and Handover Requirements

When undertaking tank demolition operations there are several procedures, we must adhere to we need to take into consideration any potential issues which can impact onto the demolition process:

  • Tanks must be clean of all products and where flammable materials have been stored, a gas free certificate must be provided.
  • Consideration must be given to the possibility of any remaining product underneath the tank floor plates, which have been collected over years through any leaks that may have been present.
  • Tanks must be isolated from the import and export lines with a clean break in the pipelines provided which can be clearly identified.
  • Consideration must be given to any additional localised ‘live’ pipework that runs near or through the operating area.
  • Reviews of underground ‘live’ services must be undertaken in order to ensure that the demolition machines to be used, do not cause any damage due to additional load bearing onto ground.
  • A review of the ground bearing capacity for heavy plant must be undertaken.

Method of Demolition

In some circumstances, tanks have been demolished using scaffolding or mobile elevated platforms and labour to burn out sections of the tank as the main demolition process, this process increases the risk of the operation due to working at height and manual handling issues this is not a preferred method and is not recommended by Technical Demolition Services.

In order to control the exposure to health and safety risks, the method of demolition for tanks is designed to minimise the use of labour and hand demolition techniques by ensuring that the majority of the work is undertaken by large, far reached tracked excavators which are fitted with large hydraulic shears.

Prior to commencing work all clearances must be provided by the client to ensure that the work can safely start.

Shears will cut through the metal skin of the tanks in a specifically designed sequence and allow the walls and roof of the tank to be folded in, whereby the sections can then be cut into optimum sizes for recycling.
