National Oilwell Varco Gets Welding Solution from Pemamek

National Oilwell Varco (NOV) has decided to purchase production and welding automation solution from PEMA for their offshore oil drilling risers fabrication. The PEMA solution is one-of-a-kind in the world and it will replace current manual welding procedures.

National Oilwell Varco is a worldwide leader in providing major mechanical components for land and offshore drilling rigs, complete land drilling and well servicing rigs, tubular inspection and internal tubular coatings, drill string equipment, extensive lifting and handling equipment, and a broad offering of downhole drilling motors, bits and tools.

Initial state

National Oilwell Varco (NOV) has been using manual welding since last decades in welding drilling risers. NOV acquired a Pema welding automation solution to its operation in Brazil to further develop the company’s success. Pema welding automation helps imporoving productivity and quality. Therefore, it was time to consider automated welding and production in riser fabrication.


NOV started to negotiate with a Finnish company Pemamek (PEMA) on the most advanced welding automation solution for their needs. The riser welding station is in the heart of the factory and in the key role of the fabrication. NOV concluded an agreement with PEMA on designing, manufacturing and delivering oil drilling riser fabrication unit – PEMA Tube Welding Lines - that include automatic cutting, bevelling and welding.

The technology is ideally applicable in offshore industry and is the most advanced welding automation solution for riser fabrication in the world.

Targets and results

The main target for NOV is to reduce production costs significantly. The other target – which is not less important – is to have new production technology that is most advanced and gets the company well ahead the competitors. With this new machinery and solution NOV will get highest productivity for their riser fabrication and less dependent on availability of classified welders.
