A promising future

摘要

Chip Edwards and Tommy Precht, Allan Edwards, USA, outline a systematic approach for the design of composite repair technologies to meet integrity programme standards. For the better part of the past 30 years, composite repair technologies have been used to repair high-pressure pipeline systems around the world. In the early days of their use, these repair systems were primarily used to reinforce corrosion features. However, through extensive research and testing efforts over the last 15 years, involving pipeline companies, composite repair technology companies, regulatory agencies, research organisations and subject matter experts, their use has extended to the reinforcement of dents, mechanical damage, vintage girth welds, pipe bends, seam welds and, more recently, leaking defects. Studies involving environmental and operational conditions have also been conducted to address elevated temperature conditions and subsea installations.
