Decommissioning

With a multitude of fields reaching or surpassing the end of their original service life, recovery of decommissioned flexibles and pipelines is critical to environmental protection.
​
Sirona Subsea believe in the ‘what goes in, must come out’ philosophy. Our business name was chosen on this basis, with Sirona being the Celtic goddess of healing water.
​
Our decommissioning range includes various tools for recovery support, as well as sealing plugs to prevent spillage during the removal and recovery operations.
​
We can support by providing:
​
- Subsea Recovery Clamps
- Subsea Environmental Plugs
