Multi-discipline installation for a biogas upgrading plant

Project objective

Build and install the mechanical and electrical installation, ensuring all work scopes are completed in a safe and controlled manner and in compliance with the site’s CDM regulations.

This was achieved by placing current and competent personnel in all roles, including site management, QA and a Health and Safety Advisor. Key controls included continuous monitoring of all activities within the work scope, regular toolbox talks, re-evaluation of risk assessments and an open-door policy so any member of the team could raise concerns about the site.

Project scope

The installation scope included:

• Risk assessments reviewed prior to tasks
• Supporting structures erected in preparation for pipework and electrical support
• All equipment installed as directed by the site plan
• All electrical work installed
• Isolation of key electrical components using lock out / tag out (LOTO)
• Pipework installation
• All pressure testing completed
• All torquing and tagging completed
• Punch lists completed and signed off by the client

Approach and delivery

Pipework supplied from overseas required inspection and rework on arrival. The PEMEC team identified and catalogued all pipework, then re-measured, cut to size and reclaimed welds where needed.

With equipment delivery dates subject to change, the team stayed flexible and completed as much preparation work as possible ahead of each delivery.

All skids needed to be lifted into position because of their size and weight. Two PEMEC team members completed a one-day assessment to operate the Manitou on site, supporting the site team and allowing work activities to be planned more precisely. A current and competent Appointed Person (AP) produced lift plans and method statements for the remaining lifting operations.

Punch lists have been completed and signed off by the client.
