Client: MVV Umwelt
Location: Devonport, Plymouth
Project: Energy from waste first plant outage
The Devonport Energy from Waste plant became operational in September 2015. When commissioning and warranty periods came to an end at the end of 2016, Denholm Industrial Services secured plant maintenance for a two-year period, which would also include two outages. The first outage was programmed for October 2017 and would last for three weeks.
MVV had to be confident that access operations would be undertaken safely, to programme and in line with their requirements. A lot of the required scaffolding had not been constructed before and therefore pre-designed solutions did not exist.
Denholm Industrial Services used BIM modelling software, traditional design skills and the operational experience of the team to design a new fit-for-purpose scaffolding solution. Construction began in July 2017 - three months prior to the start of the first outage - having identified those jobs that could be constructed prior to the outage that would have no impact on plant operations.
The solution designed by Denholm Industrial Services would see the first boiler pass constructed in an impressive 15 hours, with the second and third passes then following 24 and 36 hours respectively.
The majority of supporting scaffolding tasks were undertaken using traditional tube and fitting. The main access scaffolds were constructed from heavy duty Cuplok scaffold for speed and minimal component use.
