Decommissioning

As Oil & Gas installations come to the end of their useful lives, Subsea Services Group offers many of the services required to take the complete Subsea infrastructures out of service. Our decommissioning activity is performed utilising current vessel recourses, expertise and equipment as well as partnering as needed to achieve customer’s goals.
