Solutions that integrate versatility and economy

We plan subsea well interventions by first collaboratively setting objectives. From this basis we can then select the most appropriate approach for deployment, access, and intervention technologies. The options are myriad, starting with rig-based operations or via our dedicated vessel fleet. This latter approach significantly lowers costs compared with using drilling rigs and gives Subsea Services Alliance the versatility to conduct rigless riser-based and riserless interventions, a wide variety of decommissioning operations, and life-of-field support.
