IKM Testing performs all services related to pre-commissioning and commissioning of tie-in spools for subsea pipeline systems.
Types of operations
The following operations are the most common ones used for commissioning of tie-in spools:
• Flooding
• Cleaning
• Gauging
Flooding, cleaning and gauging is usually done by pigs, propelled through the spools.
• Pressure testing
• Dewatering
• Drying
• Preservation
• Pig placement (pipe/spool)
Dewatering and drying is normally done by use of dry/warm air or nitrogen. Preservation is done by filling the system with e.g. glycol or chemically treated water.
• Waxing
• Gel filling
Waxing and gel filling is mostly done on spools that consist of a material with low resistance to sea water, e.g. 13% chrome.
