The oil and gas industries, in the U.S. and abroad, have entered a new era of outer continental shelf activity. As the fixed structures of offshore drilling’s past slowly creep towards the end of their useful production lifetimes, the accelerating decommissioning market continues to evolve. From the Gulf of Mexico to areas off the coasts of Africa, the North Sea, and Malaysia, the decommissioning market is adapting to serve a range of depths and structures.
Traditionally, the decommissioning plan has defaulted to complete removal. In this process, the well is sealed, the drilling rig and all associated infrastructure are removed, and the seabed is ostensibly restored to its original condition. However, some of these platforms with their lattice-work superstructures of pilings, columns, beam, and pipes, have been quietly serving another purpose, below the surface, offering an artificial rocky substrate for a variety of economically and ecologically valuable fishes, including threatened species (i.e. rock fish in California and red snapper in the Gulf), invertebrates, and marine mammals.
Offshore platforms provide a refuge for vulnerable marine species, which is becoming especially relevant because nearshore habitats are more vulnerable to degradation through anthropogenic run-off, pollution, and overfishing.
Decommissioning these facilities into artificial reefs through the Rigs to Reefs (R2R) program presents an alternative to complete removal that may meet or surpass the level of environmental protection mandate by regulators. In fact, a recent study found that in California, the oil platforms “are among the most productive marine fish habitats globally.”
But not every platform is a suitable candidate for the R2R program. That’s when Great Ecology steps in. Using data collected both in the field and through scientific research, Great Ecology develops cost-effective and sustainable decommissioning strategies. We examine all options, from complete removal, to reef, to partial removal, to re-use to determine the strategy that would best serve to optimize your decommissioning project.
We understand that decommissioning planning is often an after-thought to the rush of oil exploration and the operation of offshore facilities. However, strategic decommissioning planning can result in major benefits: cost savings; streamlined permitting; regulatory compliance; environmental enhancement; and stakeholder engagement.
