Viridor Bolton Waste to Energy Plant

Spring Outage 2014

Scope of work

Please see below for programme details and crane lifting diagrams.

This job has been one of the most complicated tasks we have ever undertaken, due to general access restraints and the interfaces of the removal and replacement methods.

The extent of tube removal and replacement was as follows:

a) New side wall

b) New radiant wall panels

c) New evaporator panels

The method involved the removal of a section of the roof to gain access to lift out the old and install the new Radiant wall. It was also necessary to design, fabricate and install fully certificated temporary lifting beams and support structures.

The careful co-ordination of the rebuild process was essential. This would ensure that the pressure welding and the tube renewal process were organised in such a manner so as to maximise the access for the welders, and to allow for NDT under the difficult conditions.

Additionally, a wide range of general outage related engineering tasks were undertaken as well.

The programme duration of 26 days was accomplished in 23 days in complete safety.

We are proud to say that we have been closely associated with the maintenance of this boiler plant since 2000.

Just a quick note to say thanks to you and your team for a job well done in May

Working safely is paramount to Viridor and Thomson’s proven track record on site is a credit to everyone concerned

The main work completed this April/May, namely the changing of the boiler north wall and 4 large, internal radiant panels, was a job that we had not done before and without the detailed and meticulous pre-planning beforehand, the safe installation of the enabling steelwork, and the dogged determination on everyone’s part to get the work done, this job could not have been completed. As it was, all the work was completed on budget and on time and everyone went home safe

Thanks again

Steve Robinson
