Title: Troll, Haltenpipe showcase offshore pipelay advances

Abstract

Pipelines installed on the Norwegian continental shelf represent current offshore pipeline installation technology for pipe size (up to 40 in.), water depth (to 540 m) distance between pigging stations (up to 800 km), and complex seabed intervention and landfall construction. Furthermore, the number of deepwater pipelines worldwide has triggered significant advances in the development of pipeline repair. The Troll oil pipeline and Haltenpipe projects faced technical challenges: irregular seabed, conditions requiring highly accurate mapping, careful routing, free-span design, seabed preparation works, and special low-tension lay techniques. The two projects, therefore, have in many ways benefited from each other and been run practically as one large integrated project. The paper describes the design, route preparation, and installation for both pipelines.
