Zap-Lok™ and MPS® presented as key technology at Oil & Gas Asia 2019

Our Director and General Manager in Asia, Murray Ross, presented the benefits of our technology at the Oil & Gas Asia Conference in the Kuala Lumpur Convention Centre, Malaysia.

Murray was invited by Subsea UK to contribute to its session which addressed issues and shared the latest developments in the energy industry.

Cortez has been working with NOV-Tuboscope for many years to deliver Zap-Lok™ mechanical connectors to the Malaysian and worldwide offshore market for pipelay which is faster, stronger and cheaper.

The Zap-Lok™ technology is proven with more than 7000km of subsea hydrocarbon pipelines installed worldwide and zero recorded failures in operation of over 70,000 joints.

A challenging environment can render traditional techniques inefficient, uneconomic or impossible, and Murray explained how this solution can offer a weld-free alternative to improve safety, dramatically cut costs and reduce our carbon footprint.

The event included other speakers from Wood and Enpro Subsea and delegates heard about many ingenious technologies transforming our industry daily.

Five Reasons to Lay Zap-Lok™ and MPS® Pipelines

A vast volume of subsea pipelines are planned and built every year to bring the world’s energy supplies from the seabed to the surface.  In an industry continuing to adjust to new norms, its vital we work together to drive the adoption of ingenious technology to make the process smarter.

Welding is the predominant method for fabricating pipe systems across the sector.  But there are several applications where traditional welded pipe connections become inefficient, uneconomic or impossible.  Cortez Subsea works with NOV-Tuboscope to pioneer Zap-Lok™ mechanical connectors into new markets for pipelay which is faster, stronger and cheaper.
