inspection, maintenance, and repair (imr) equipment

IMR equipment covers a broad range of products, mainly designated to fields in their infancy that require conservation and integrity continuity plans in place for insurance purposes, but also for aging fields where a weakening or breach in an existing pipeline is identified through visual inspection or intelligent pigging.

​

Typically, the equipment within this range is installed in conjunction with the product commissioning , or to allow the continued operational use of the product in question should integrity be compromised.

​

The IMR solutions that we offer are utilised to ensure that the clients’ asset is protected and maintained for the required duration of its intended lifespan.

​

Our experience in IRM products includes:

​

  • Pipeline Repair Clamps (Structural & Sealing only)

  • Subsea Connectors

  • Continuity Clamps

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 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

  • ROV Installed Flanges
