Hot work has been performed on Draugen continuously during the length of the contract, and still is being performed. This habitat was in continuous operation for more than three weeks, with all welds conducted ahead of schedule and with no delay between welding points, due to eliminating the need for several smaller habitats being constructed. To ensure that the habitat remained pressurised during operations we connected three of our market leading, high-capacity fans in series against one habitat system. We solved this by constructing a 600 m3 habitat, covering the length of the new living quarters. Our focus during the planning and execution of these habitats has been to have little or no delay between the different welds and welding points.įor the structural work and installation of the new living quarters we were challenged by the contractor, Aibel, and the operator, Shell: Can StS somehow include all the welding points for the tie-in for the new living quarters in one habitat, ensuring maximum efficiency for the hot work and minimal or no delay. For the pipeline phase, one our field engineers and project managers has planned and built 49 habitats, facilitating 172 welds, while phase two has seen more than 35 habitats, with 73 welds performed. More than 84 habitats of numerous sizes and shapes have been constructed on Draugen, facilitating 245 welds. Due to the amount of work being done simultaneously, the need for thorough planning and flawless execution has been, and remains, crucial.
DRAUGEN PLATFORM FULL
Shell has stressed the importance of production being uninterrupted during the modifications, which has led to more than 245 welds being performed while in full production. A new pipeline has been installed, structural changes have been made and an entirely new living quarters installed.
Draugen is undergoing major modifications while still being in production.
