Requirement for the solutions was that it would include state-of-the-art technology and brings competitive edge for ST3 in heavy tubular production. Furthermore, it should be fast to learn and easy to operate, but also provides fast return on investment.

To turn the goals into practice, ST3 Offshore invested in full PEMA production line with uniquely designed systems, such as welding and material handling stations for TP manufacturing.

Thanks to the PEMA know-how and profound understanding of automated production lines, the complete TP production solution was designed with optimal welding processes and high capacity work flow. The delivery included efficient and fully integrated plate joining station with other plate processing machinery. The plate joining station has plate manipulation functions to faciliate accurate aligning and it has effective Tandem SAW welding process with integrated inductive pre-heating equipment.

 The delivery also included two longitudinal seam welding stations with Extra Heavy Duty Column&Booms, and an innovative gas burner pre-heating system. Additionally, PEMA Horizontal Flange Fitting station (HFF), which enables welding in the same station, was delivered to carry out the demanding work phase of heavy flange assembly.

The core of the solution is the assembly of TP which is done in PEMA 400tn assembly line that is equipped also with gas burner pre-heating system. The line consists of PEMA Assembly station, PEMA C&B Tandem SAW process, rollerbeds and welding platform with two SAW Tandem heads for outside welding, but also rollerbeds for milling. Another three sets of 400tons rollerbed ensembles were also included in the delivery to enable material handling for secondary steel and welding examination.
