Since its inception, AOS has established a solid reputation for delivering high levels of customer satisfaction. By responding to the changing O&G market, we have completed a number of preservation projects and programmes in South East Asia and are expanding the same service to other strategic locations. We offer a choice of Roadstead or Yard bases for preservation projects. With our trusted partners we can use the latest in technology – digital, chemical and AI to digitalise the rig stack process, so it is done once, right and smart. All works are QA-QC every ninety days with full reports.
