Expansion of speciality chemical plant

Location: Warrington
Client: The Perstop Group
Project: Expansion of speciality chemical plant
Contract Value: £4.3m

The Perstorp Group is a world leader in several sectors of the speciality chemicals market. Boulting provided mechanical, electrical and instrumentation engineering to develop the Warrington manufacturing unit. This included an expansion of the Caprolactone Monomer and Polymer plants.

The first contract was solely mechanical in nature. Boulting then went on to secure further electrical and instrumentation work across five phases.

Dedicated off site fabrication for efficiency

Much of the fabrication took place at our mechanical workshop in St Helens, a dedicated 9000m2 facility. Over the project, 14,500 pieces of pipe work were fabricated and supplied, 18 columns and vessels of various types were installed along with 14,500 metres of stainless steel and carbon pipe, 28 pumps and pipe supports.

Boulting design team delivered 1450 isometric drawings

Contracted works were broken down into phases and issued in packages, initial installation started from 20% design. Works were assessed in order of constructability and issued as design packages, towards the end of the contract, emphasis changed to pre-commissioning and completion.

Some 1,450 isometrics were drawn up throughout this process.

Six phases completed by Boulting E&I team

The Electrical and Instrumentation works were split into phases with each phase awarded individually.

Installation of the main containment system from the switch room to the new Monomer extension.

Installation of main power and control cables from the new Monomer switch room.

Installation of instrumentation cables and containment to field control equipment.
