Inspection, Maintenance, and Repair
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:
​
- Structural Repair Clamps
- Pipeline Repair Clamps
- Subsea Connectors
- Continuity Clamps

Sealing was conducted to 1.5x MAOP on a 3LPP coated pipeline with simulated reduced wall-thickness due to channel corrosion, as a means of allowing our client to install our equipment directly onto the line without completing a laborious coating removal operation, saving significant vessel time.
A 55t SWL Installation Frame was also supplied to assist with subsea lifting and positioning. (See right)
