Neptune Marine Services says it has won a $6 million contract from Japan's MODEC for work on a floating production, storage and offloading facility in the Carnarvon Basin.
The Santos MODEC Venture 11 floating production facility is 160 kilometres north of Karratha.
Neptune will be using a vessel supplied by Singapore-based Pacific Radiance Group to complete the job.
The work is expected to be performed in January.
Neptune chief executive Robin King said it was an exciting contract for Neptune.
Neptune shares were steady at 3.1 cents at 8.15am.
