Nonmetallic Composite Repair of Offshore Crude Oil Pipeline/Riser System

Nonmetallic Composite Repair of Offshore Crude Oil Pipeline/Riser System
Nonmetallic Composite Repair of Offshore Crude Oil Pipeline/Riser System
For decades, composite repairs have been widely used to restore onshore pipeline integrity. As subsea pipelines age, a reliable repair method is crucial to maintain pipeline integrity and ensure safe hydrocarbon transportation. This paper presents an alternative repair method using nonmetallic composite materials, qualified to ASME PCC-2 standard...

Subsea Pipeline Repair Readiness Approach for Efficient Underwater Repairs
Subsea pipelines, such as in-field flowlines, trunklines, etc., are an integral part of all offshore field developments. Pipeline damage can occur either during construction phase or during the life of field. Critical pipeline damage such as leak, rupture, or crack requires repair to be performed on an emergency basis. Repair readiness is being...

Safely repairing subsea flanges on flexible flowlines with a flexible bridging jumper structure
As offshore pipelines age, the oil and gas industry must properly maintain equipment to prevent leaks. In subsea flowlines, leaks sometimes originate from aging flanges. These flanges must be replaced. Historically, replacing the flange has required a lot of time. Different costly approaches are available, from subsea reparations to flowline...
