Environmental Engineering

Improving or maintaining the quality of natural and human environments.

Environmental engineering is the application of engineering and scientific principles to improve or maintain the quality of natural and human environments. It is core to Xodus’ integrated approach. It results in environmental, health and social risks being thoroughly understood and mitigated by design.

Our environmental engineering capabilities cross all our environmental services – from undertaking lifecycle assessment at concept selection, to providing practicable design mitigation advice at ESHIA or engineering design stages, and on to supporting complex consent applications for construction and operation. By embedding environmental engineering across the range of our technical services, we apply both engineering and scientific approaches to problem-solving, allowing preventative or mitigative options to be fully investigated before we make our recommendations.

We deliver environmental engineering solutions in the smartest and most efficient way – from produced water Best Available Technique (BAT) assessments to environmental critical equipment studies. We work closely with our safety engineers to provide an integrated service on emerging requirements such as the European Union Offshore Safety Directive.

Our environmental engineering services may be delivered as part of larger studies such as Front End Engineering Design (FEED) or detailed design programmes, or as discrete studies, such as system optimisation, individual technical assessments or problem solving. Working arrangements are also adaptable with Xodus environmental engineers working in-house as well as working as part of our client’s (or contractor’s) team.

Xodus understands and supports design studies under a range of global regulatory regimes, from prescriptive end-of-pipe regimes, such as in the Gulf of Mexico, to understanding and demonstrating BAT or the ALARP approach to risk reduction.

Our environmental engineers come from a range of backgrounds such as process engineering, chemical engineering, air pollution control and acoustics. The team has wide-ranging experience in the energy industry, including upstream / midstream oil and gas and renewable energy sectors, as well as other areas, such as the chemical industry and ports. Clients value the benefits such cross discipline expertise brings as it greatly increases the technical capability we offer.
