Abstract:This paper will describe the risk assessment exercise carried out for pull-in and tie-in of the pipelines at the Troll GBS (Gravity Base Structure). The Troll Platform GBS will be installed and then the pipelines for the export of gas have to be pulled into the bottom of the riser shaft. Once the pipelines have been pulled in and sealed they have to be tied into the already pre-installed risers in the GBS. This pull-in and tie-in operation presents many hazards associated with working in a congested space at t… Show more
