Heat-shrinkable sleeves have been used for over 30 years to protect the field joints on both onshore and offshore pipelines and continue to be a commonly specified technology. As operating conditions on newly constructed pipelines become more severe and performance specifications are developed to meet the requirements, new field joint protection systems must also be developed to meet individual project needs.

This paper provides case histories of two recent offshore projects where new heat-shrinkable sleeve products were developed to meet the needs of the pipeline specification. Both case histories cover the project requirements and describe how the existing technology was adapted to develop a joint protection system to meet the requirements and also where new technologies were employed in an engineered system.

Heat-shrinkable sleeve technology has evolved from being a product that may be viewed in the industry as a simple “shrink-wrap”, to being high performance, multi-layer systems.
