Plant Engineering

Share on:

Plant Engineering is the function responsible for planning, designing, specifying, installing, modifying and maintaining plant facilities, systems and equipment.

Our Plant Engineering team incorporates engineers experienced in the design and maintenance of industrial processing plants.

Our primary customer groups are those who are in the business of processing, refining, handling, manufacturing or treating petrochemicals, gases, water, waste, bulk materials, minerals, food products or manufactured products for use in other processes or for sale to others.

Are you looking to either expand your business, increase production, reduce bottlenecks, manufacture new products, improve efficiency, upgrade to new technologies, refurbish or repair? Our offering ranges from machine engineering and finite element analysis to fully integrated, multi-discipline industrial plant design.

  • Mechanical plant specification and detailed design
  • Plant operation and control system design
  • Pressure vessel and piping design, specification and stress analysis
  • Fluid pumping, handling and storage equipment design and specification
  • Computational fluid dynamic modelling
  • Power drive and transmission specification and selection

We utilise the latest 3D modelling software for each phase of project design development, from conceptual to definitive design, right through to the production of documentation for construction. We’ll customise our delivery to suit your project development strategy - we are accustomed to roles in a wide range of contractual relationships including: due diligence, design consultancy, independent inspection, EPCM, EPC, D&C, owner’s engineer, and strategic alliances.

Hydrochloric Acid Synthesis Unit Design


We provided a major chemical manufacturing client with a front-end engineering design package for a new hydrochloric acid synthesis unit for a plant in Niagara Falls, New York. We initiated detailed design activities in January 2013 and continued with a team of up to 20 engineers and design professionals working on the project through November 2014. More than 27,000 person-hours were expended on the project.

The major scope of work elements included:

Stoke Bardolph WwTW Biogas Plant


The Stoke Bardolph project involved the construction of a 2-MW Energy Crop Digestion and Combined Heat and Power (CHP) plant on land adjacent to Stoke Bardolph Sewage Works in Nottingham. The purpose of the project was to provide power generation from bio solids which are used as an agro fertilizer to grow maize.

The plant comprises 10,000m2 of silage clamps, milling and fermentation followed by digestion with the biogas being used to power the CHP plant. Power generated is used to supply the adjoining Sewage Works, with any surplus being fed into the National Grid network. Stoke Bardolph is the first large-scale CHP plant in the UK to be powered from maize energy crops.
