Troll Phase 1 offshore pipelines, a project overview
- A/S Norske Shell, Bergen (Norway)
Construction of the Troll Phase 1 pipelines and power and communication cable offshore Norway was completed 21st of November 1995 when the rockdump vessel Tertnes left the field. The majority of construction work was carried out during the 1995 season following detailed design and engineering preparations. The main innovations and/or experiences that made this offshore pipeline project so special are: 36 inch/16 inch pipelines deepwater platform pull-in/tie-in; 36 inch/40 inch pipelines installation on a soft uneven seabed; associated design/execution of extensive rockdumping; installation of very large spools before pipelay; and deepwater J-tube pull-in and soft seabed trenching. Following this introductory overview article, each of these subjects is covered in detail in separate articles, respectively Nonner et al. (1996), Thorvaldsen et al. (1996), Brennodden et al. (1996), Buchan and Kuhlmann (1996), and Rodrigues de Miranda et al. (1996).
