Decommissioning has become an integral part of the offshore industry over recent years as operators seek to reduce their asset stock and remain profitable at the same time. With the ever-increasing pressure to save money, it’s important that oil companies have a reliable and expert supply chain to rely on for guidance and support.
Decommissioning, as we have seen in the case of recent North Sea projects, is set to be increasingly technically challenging, and with that, costly. From initial planning to the site clean-up, a decommissioning project can also take a significant period — potentially years to complete.
As we eagerly await the annual facts and figures from industry analysts, every sign points at 2017 as being a positive year for decommissioning progress, particularly in the North Sea.
In January, we discussed in the Claxton blog predictions made by Oil and Gas UK, who, in their 2016 Decommissioning Insight, evaluated what the industry planned to do collectively to sustain efficiency improvements and cost reductions.
Since the turn of the year, there have been key developments which has seen a huge decommissioning shift, and although nobody can say for certain what the future will hold, there is no doubt that the events of this year will influence the future of the sector.
In this blog, we will compare predictions made earlier in the year with the events that have transpired, and give an insight into how offshore decommissioning is shaping up for the future.
Any structure submerged in the sea will eventually host a community of marine organisms, making biofouling and marine growth an unavoidable issue within the offshore oil and gas industry.
As previously discussed in the Claxton blog, 50% of all technical integrity incidents are related to ageing assets, so it’s important to slow down this ageing process by introducing preventive measures. Marine growth in particular has huge consequences for structural integrity, hydrodynamic efficiency, and survivability of assets, and these measures can mitigate some of the costs that are amplified by the effects of biofouling.
Read on to find out the effects of biofouling, the issues it can cause, and the plans we can build on to help prevent asset degradation.
The oil and gas industry has embraced risk-based inspection (RBI) as a way of fending off unplanned shutdowns, unexpected future costs, and potential threats to health and safety offshore. But are they being used as accurately or as frequently as required?
RBI seeks out the potential of an asset’s failure, providing a ‘risk snapshot’ in time. The risk-based approach has been utilised for some time within refineries, and petrochemical and chemical facilities, which have reaped the benefits of significant cost savings.
By their own admission, the British Engineering Services describe RBIs as: “If implemented correctly, an RBI approach can improve asset integrity management, as well as increase the organisation’s efficiency, while reducing plant downtime and increasing income.”
