Paul Wurth’s service team has achieved high performance during the strategic renewal project to reduce emissions and extend the life of SSAB EMEA’s Lulea steelworks’ coke oven battery. On 14 December 2021 SSAB and Paul Wurth’s service team signed the performance achievement document for the Engineering, Procurement and Construction revamp of the coke oven battery at Luleå steel works in northern Sweden. Paul Wurth’s scope of work included the replacement of the entire raw gas system, along with the ascension pipes, goosenecks, the single oven pressure control SOPRECO system for emission reduction, Gas Collecting Main and off-takes. The replacement of the entire raw gas system was carried out with the 54-oven coke battery in operation. This was in order to minimize production stoppages and guarantee sufficient coke oven gas availability for the heating up of the battery itself.Additionally, the Paul Wurth team, using an innovative technique, took the advantage of the ovens being empty during the GCM replacement to substitute the battery ovens’ roof, including several upper refractory layers, transversal and longitudinal tie rods and the charging machines’ rails.The completeness based project achieved the required performance level in record time: about 22 months from order award. The team successfully overcame the constraints of COVID-19 during the design, procurement, delivery and installation phases.
