Under the contract, Neptune subsidiary Link Weld Engineering will build four riser bases and one pipeline end terminal structure for Van Gogh.

"Having established a very strong relationship with Apache, we are delighted to be working with them again on the Van Gogh project, strengthening our partnership as they continue to expand their exploration and production efforts in Australia," managing director Christian Lange said.

"Our customers are starting to engage us on larger scale, higher value projects in line with our expanding suite of capabilities and increased market presence," Lange added.

The Apache contract was one of two worth more than $A5 million that was awarded to Link Weld.
