Project Description

A large proportion of the UKCS offshore infrastructure have reached the end of its economic lifetime. Hence, decommissioning is required when every option for extending the assets life has been exhausted.
This PhD project tends to examine the challenges of decommissioning marine pipelines and bundles. Subsea bundles are subsea tubular structures that can contain flow lines, process lines, chemical injection lines and umbilical cables that connect a subsea field to a host facility. Currently most bundles have been left in situ or the ends are rock dumped. This project will look into assessment of the current methods used for decommissioning of bundles, comparative assessment of the methods used for other structures and how methods already in place can be implemented in this project. It will include a review of current practices of removing pipelines and bundles depending on the soil type associated with those structures and examine their differences in association with legislation and environmental impact.
The project will look at the jetting process as a means of sinking the bundle into the sea bed to a depth recognised as being safe (typically 60cm in the UKCS). This will be done on scale experimental models with different grades and densities of different seabed materials. Environmental impacts associated with the jetting process will be investigated.
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 student will be one of the first graduates that will work on the research area that will bring potentially new technologies able to tackle challenges decommissioning faces in the area of offshore geotechnics


This studentship forms part of the National Decommissioning Centre, Centre for Doctoral Training. All of the NDC CDT projects will have substantive industry/regulator/NGO links/support. This support is currently being discussed with appropriate companies and organisations.
