Xodus’ experience and breadth of expertise helps operators in the energy sector to protect the environment, comply with regulations and meet their business goals.

Across the lifecycle

Our independent, robust approach to environmental services supports operators worldwide on and offshore throughout asset and project lifecycles.

Clients call on our expertise from licence acquisition, feasibility and planning, options selection, Front End Engineering Design (FEED), execution and operation right through to decommissioning. We help them to remain compliant within their jurisdiction and ahead of emerging regulations and technical advances.

Wide-ranging expertise

Our team of environmental advisors, scientists and engineers includes subject matter experts; terrestrial and benthic ecologists; marine mammal experts; oceanographers; acousticians; traffic, social and fisheries professionals.

We also have a pool of health, safety and environmental professionals who have years of experience of management systems, auditing and training. 

Environmental engineering 

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.

Performance improvement 

We provide Environmental Management System (EMS) support as well as targeted bespoke auditing and training, keeping our clients compliant and ahead of the curve on new standards such as the ISO14001:2015. 

Our worldwide environmental legislation web app, RegTRAX, is designed specifically for drilling clients who need to quickly identify and understand the legislation that applies to their operations. Other areas of work include sustainability, energy efficiency and waste management.

Environmental and social impact assessment 

Our Environmental and Social Impact Assessment (ESIA) experience ranges across energy and linear infrastructure projects from large greenfield developments in the deepwater Atlantic Frontier, brownfield modifications in the southern North Sea, wind farm developments in Africa, tidal devices in Ireland, interconnectors across the North Sea, and onshore refineries in the Middle East. These are supported by our due diligence and lender interface capability. We hold the IEMA quality mark for impact assessment.

We draw on our in-house subject matter experts and network of trusted third party contractors across the world to establish the most suitable team for the job. We also routinely support our clients in all aspects of data collection and manipulation throughout the project lifecycle from scoping and interpreting marine environmental surveys, and managing data, to the use of GIS to track and monitor changes over time and to assist in constraints mapping.

Environmental modelling 

Our in-house modelling capability covers atmospheric emissions; gaseous and particulates, aqueous discharge, noise propagation and oil spill simulations, making use of our experienced staff and cutting-edge software such as, ADMS, CadnaA, OSCAR and DREAM. Geographical Information System (GIS) practitioners and software developers assist us in providing our bespoke web-based environmental products.

UK Continental Shelf (UKCS) compliance

Our compliance experts support clients with the full spectrum of permitting – Xodus prepares one third of all chemical permits for North Sea operations.

Our experience of working with operators worldwide gives us a unique perspective on compliance and enables us to offer cost-effective and efficient environmental solutions.

Our permitting knowledge, coupled with in-house software expertise, has led to the development of Xodus’ web app, EmTRAX. It covers all operational environmental data tracking for both internal and external reporting.


Our acoustics services cover the impacts of noise and vibration in the environment and on people across the energy and infrastructure sectors.

Our capability includes the measurement, assessment, prediction and control of airborne and underwater noise. The services on offer are diverse – from the impact of underwater noise of marine mammals to detailed engineering noise and vibration control studies, from PA and alarm design reviews to policy and legislative advice.
