With over two decades of experience in the North Sea and internationally, AquaTerra has built a strong reputation for delivering safe, efficient, and compliant support across all phases of the decommissioning process. We specialise in construction-led decommissioning solutions, tailored to meet the unique challenges of the Engineering, Preparation, Removal, and Disposal (EPRD) process for fixed production assets

Utilising a combination of multi-discipline construction teams, innovative access methods and proven destruct and cutting techniques, AquaTerra have been involved in some of the most significant and challenging decommissioning projects undertaken in the UKCS.

At AquaTerra, we believe that decommissioning requires a different approach. Unlike the requirements on a producing asset, where the focus for engineering modifications and upgrades is based on comprehensive, engineering-focused solutions, we believe that a different philosophy centred on finding non-complex, fit for purpose solutions is more appropriate.

We approach each project with a safety-first mindset and emphasise strategic decision-making, where knowing what actions to avoid can be as crucial as deciding what steps to take. Our expertise lies in developing innovative and intelligent solutions to overcome both simple and complex decommissioning challenges.

AquaTerra’s experienced teams bring a strong track record of managing decommissioning scopes safely, on time, and within budget, even in hazardous environments. From preparation to final disposal, we are equipped to support every stage of the facilities decommissioning process.

Formed in 1992, as specialist HSE, technical and project management consultancy, 100% focused within the decommissioning, decontamination, dismantling and demolition (DDDD) sectors. The company has successfully delivered in excess of 1000 projects across Europe, Americas, Africa and Asia.

Working exclusively for owners and operators of assets on mainly high hazard sites in the oil & gas, petrochemical, power generation, pharmaceutical and nuclear industries, RVA has developed comprehensive ISO accredited (9001, 14001 and 45001) fit for purpose integrated management systems, that can be rolled out on any decommissioning assignment and to ensure they are fully compliant with local legislation e.g. UK CDM Regulations.

RVA’s prime driver has always been based on an unswerving commitment to achieve, within its projects, the highest standards of HSE excellence, best value, thus maximising the monetisation of the asset. The RVA team includes Fellows, Members and officers of the Institute of Demolition Engineers and Institute of Explosive Engineers as well as Members of the Association of Project Safety (CDM-PD). It holds the necessary skills, knowledge and experience to intelligently and collaboratively interface with all project stakeholders to deliver using best available techniques, safe, efficient and cost-effective outcomes on every occasion.
