General

This document describes the various phases of the demolition work and the responsibilities of the various parties involved in the process, and highlights some of the pitfalls that may be encountered, for the following types of structures:

• vertical cylindrical, non-refrigerated storage tanks built in accordance with BS 2654, API 650 or a similar code

• vertical cylindrical, refrigerated storage tanks built in accordance with BS 7777, API 620 or a similar code

• column-supported LPG or ammonia spheres built in accordance with BS (now PD) 5500, ASME Section VIII, Division 1 or 2, or other national pressure vessel codes.

Although some information is included on demolition procedures, this document does not provide a comprehensive list of all methods that may be proposed by demolition contractors.

This document also assumes that the tank material will not be reused to construct a new tank.

Refrigerated Storage Tanks

While at present there is no immediate industry need for recommendations on the demolition of refrigerated storage tanks, a section has nevertheless been included covering this type of tank (Section 9).
