We conducted a review of the management of marine growth during the decommissioning of offshore oil and gas installations on the UKCS for the Oil & Gas UK Ltd Joint Industry Project (JIP) on Decommissioning.
During the decommissioning of offshore structures, marine growth constitutes a waste that has to be managed within the environmental legislative framework and the capabilities and capacity of the decommissioning supply chain.
The study provided an overview of marine growth characteristics on offshore structures in the North Sea, and assessed current practice for marine growth management during the decommissioning process.
The study also highlighted where opportunities may exist for new approaches and technologies.
The team at BMT was able to draw on their experience of marine growth studies and decommissioning projects; this was coupled with the experiences of four decommissioning contractors who operate facilities at which most UK and Norwegian decommissioning projects have taken place.
The methodology currently used by the industry to access marine growth on offshore structure was developed by BMT.
Using their detailed understanding of the characteristics of marine growth on offshore structures, our specialists can:
We were engaged by the Department of Industry on behalf of the Marine Estate Management Authority (MEMA) to provide strategic risk assessment advice for the TARA process for a pilot project for the Hawkesbury Marine Shelf Bioregion and then for the State-wide marine estate.
BMT developed a 3D hydrodynamic and water quality model of the region around the Abrolhos Islands in Western Australia. In collaboration with BMT and the University of Western Australia, model results were used to assess the impact of proposed finfish aquaculture on the surrounding environment.
BMT was commissioned by the Abu Dhabi Environment Agency to undertake advanced numerical modelling at a site within the Arabian Gulf. This was to assess the viability of developing aquaculture operations at the site.
Seqwater is the Queensland Government Bulk Water Supply Authority and manages over $11 billion of water supply infrastructure - including dams and weirs, conventional water treatment plants, a desalination plant, the Western Corridor Recycled Water Scheme, as well reservoirs, pump stations and more than 600 kilometres of bi-directional pipeline network. As part of Seqwater's climate change risk management, this project undertaken by BMT assessed climate change vulnerability of Seqwater's built assets.
