Working alongside the clients engineering department and DNV, Stowens project team devised a plan to remove & replace the damaged section of rack weighing in at 7.5t. This process is believed to be a world first for a rig of this size and class and certainly a first for our client.
The plan was executed by jacking the rig up to the required elevation and building a habitat around the damaged leg section. The habitat was required to give protection from adverse weather conditions in the region, which were often below 0°C with high wind speeds and heavy rain.
Stowen mobilised a 14-person team of multi-skilled rig builders comprising of heat treatment techs, 6GR coded welders and fitters, L3 riggers & NDT inspectors to commence the repairs.
Working 24hrs a day in often very challenging conditions the team was able to complete the repairs without incident, on schedule and within budget.
