The paper presents the synergies between two proven Bundle systems:Pipeline Bundles and Riser Bundles, based on extensive track records: 70 Pipeline Bundles over 35 years and 6 Riser Bundles over 15 years.
Despite the two Bundle systems being developed independently, the synergies between the design requirements, the components and the towing requirements are remarkable. This shows that despite the different applications the technology has been developed with the same technical understanding and demonstrates how the merging of different technologies can bring benefits to the industry.
The paper includes a general description of the two Bundle systems, including fabrication and installation methods. A review of the similarities and differences between the two systems is presented.
The benefits of synergies are discussed, based on practical examples of new developments:
– Design: Pipeline Bundle design adapted to Riser Bundle for enhanced thermal insulation performances and bundle section simplification.
– Fabrication: feasibility of fabrication and launching of a Riser Bundle from a Pipeline Bundle fabrication site (Wester Site, Scotland).
– Installation: development of methods for installation of Pipeline Bundles in deepwater and long-distance towing of Riser Bundle in shallow waters.
The synergies discussed in the paper result in enhanced capabilities for Bundle systems, including: improved system operating performance, increased systems applicability extent (allowing development in deeper waters and new areas). These systems can thus be considered for new geographical areas.
