HYDRATIGHT completed an upgrade project on a section of subsea pipeline on the North West Shelf of Western Australia, according to a June announcement.

Contracted by Quadrant Energy on behalf of the John Brookes joint venture, Hydratight engineered, manufactured, delivered and supported the installation of an 18 inch MORGRIP connector the pipeline.

Located on the North West Shelf, the subsea pipeline is 54 kilometres north east of Quadrant’s Varanus Island facilities.

Hydratight said two of the company’s experienced engineers, Mark Fisher and Bob Till, were embedded in the offshore installation team.

Mr Fisher said due to safety and environmental expectations, the company worked with a DNV GL inspector who flew in from Singapore to witness all aspects of the upgrade.

“It also meant an independent critique of our manufacturing procedures.”

“The component parts were of extremely high specifications and we had strict rules on forging and manufacturing.  These included the use of a compliant biodegradable mineral hydraulic fluid used for activating the tensioners and flushing and cleansing all tooling.  We ensured no other unassessed hydraulic fluid was used,” he said.

A Quadrant representative oversaw the factory acceptance test of the completed connector in the United Kingdom, before witnessing a second test and diver training on arrival in Australia.

Hydratight’s product featured corrosion resistant alloy cladding, composite graphite seals, company’s ball and taper technology and subsea tensioning equipment.
