Allseas / Activities / Heavy lifting / Removal Removal When oil and gas fields end production, their facilities need to be removed and disposed of (or recycled), a process known as “decommissioning”. Decommissioning of offshore structures is a highly complex and technical exercise that poses significant health and safety challenges. The process encompasses the planning, approval, implementation, removal and disposal (or re-use) of an offshore structure. In the North Sea alone, around 470 installations will require decommissioning over the next 30 to 40 years. Royal Dutch Shell is leading the way; in February 2015 the company set out plans to decommission the iconic Brent platforms in the oilfield north-east of Shetland – using Allseas’ heavy-lift vessel . Removals began with the 24,000-t in 2017. The Brent Bravo topsides followed in 2019 and the Brent Alpha topsides will follow in 2020.
