Our professionals work on some of the world’s most remote and exciting projects, and we’re strategically positioned to capitalize on the expanding opportunities in global markets.


As we’ve grown, we’ve learned the value of customizing our services to meet evolving industry needs, and of partnering with the world’s best providers in each field.

In 2006, we established our Queensland division to deliver specialized operations solutions to the minerals-processing industry.

Two years later, in 2008, we made three significant acquisitions: Shell Oil & Gas (Shell group), Sandwell International Inc., and Vector Engineering Inc.

Today, with this strategic partnership and change of company name (Mosaic OIL & GAS), make us a total solution provider to the global resources industry, able to provide a full range of infrastructure and world class engineering services.
