New cleaning and waste management technologies in offshore energy installations - National Decommissioning Centre


Project Description

A transition to a sustainable energy system calls for reducing waste, hazards, environmental and economic impacts. This project aims at developing new knowledge-based cleaning and waste management technologies that will contribute to that goal. It will be based on the fundamental science underpinning the stability and properties of slurries containing hydrocarbons, scales and heavy metals.
Management of hazardous substances and the long term liability associated with the presence of unexpected pollutants pose a serious challenge during the life cycle of every offshore energy project. In the context of decommissioning, ‘Making safe’ activities, including cleaning, venting and purging, isolation, and waste management, together with topside preparation and onshore disposal, remediation and monitoring, account for circa 9% of the total cost.

Solid hydrocarbon deposits in pipelines and facilities form a matrix of waxes and asphaltenes, becoming nucleation sites for scales precipitation and trapping pollutants such as PAH and mercury. Those scales are also a source of radioactivity (NORM). The sludge at the bottom of tanks and slurries during flushing contain hazardous substances as mentioned above. Colloidal theory offers a tool to understand these processes, of paramount importance to tackle the cleaning and disposal of waste during operations and decommissioning.

Experiments (density, rheology, phase behaviour, interfacial tension, interfacial rheology and viscoelasticity, analytical chemistry, imaging techniques) and models will be investigated to optimise the cleaning method, waste treatment and disposal route of those complex mixtures.

The successful student will benefit from being part of a new and exciting decommissioning research centre working in Newburgh, Aberdeenshire, along with other PhD students, industry and academics among others. NDC includes state-of-the-art engineering laboratories and hangar space for the design and development of decommissioning technology, as well as a suite of environmental commercial testing facilities. At the heart of the Centre is the Decommissioning Immersive Collaborative Environment (DICE), a high-tech digital visualisation suite.

The successful candidate should have, or expect to obtain a UK Honours Degree at 2.1 or above (or equivalent) in Chemical Engineering, Petroleum Engineering, Mechanical Engineering, Chemistry, physics, environmental engineering.

Essential background and Knowledge: Experimental thermodynamics
Organic and inorganic chemistry

Students will have the opportunity to study elements of the MSc in Decommissioning see http://www.ukndc.com/skills-and-learning/msc-decommissioning/ to gain a broader understanding and knowledge.
