The Oil & Gas industry is showing a growing demand for systems and equipment that allow for quick repair interventions on damaged subsea pipelines. Fiber-Reinforced Polymer (FRP) composite wrapping systems have been introduced and accepted as alternative temporary repair systems. Composite wrapping is an efficient repair method and well established for onshore pipelines. It has been successfully extended offshore and, recently, for subsea in shallow water applications with divers. This paper provides a critical overview of the subject technique, including advantages over traditional repair methods, pipe defect applicability, reference standards and specific state-of-the-art technology. Composite wrapping solutions for diver-less and deep-water applications are not yet available on the market. Critical challenges to overcome in order to afford the use of this technology for these applications are outlined. A development project is currently ongoing to achieve a deep-water composite wrapping repair solution with the aim of proposing innovative and cost-effective methods in support of subsea asset Inspection, Maintenance and Repair (IMR).

Erosion of piping systems is a significant issue for many operators of hydrocarbon infrastructure causing a significant loss in revenue and an increase in installations, repair and maintenance costs. Currently, the use of erosion resistant coatings, reduction of flow rates and replacement/repair are the only mitigation controls against erosion. INTECSEA has been developing a novel Erosion Control Technology (ECT) that can reduce the impact of erosion on piping via the strategic placement of custom engineered inserts into the product stream. The two phases of ECT prototype testing under real-field multiphase conditions representing gas condensate fields have been performed at the E/CRC (The University of Tulsa). The superficial gas velocity (VSG) was varied from 31 m/s to 23 m/s with the superficial liquid velocity (VSL) fixed at 0.04 m/s and the sand particles were varied from 300 μm to 75 μm. The metal loss due to erosion was monitored using a set of UT probes in two consecutive elbows spaced 11D apart oriented in a vertical-horizontal loop. The erosion tests using prototype ECT inserts have shown a significant reduction in erosion at both the gas flow conditions. Computational Fluid Dynamics (CFD) has been a backbone in developing this technology and CFD results have shown good correlation with the physical tests. Discussions with leading operators for a field trial targeted for 2020 is ongoing.
