Keys to Maintaining Blockage-Free Subsea Tiebacks

Long subsea tiebacks are gaining popularity in the current economic environment. As the length of the tiebacks increase there is greater interest in single flowlines vs. the conventional dual or looped flowline approach. However, there is great concern with long single line tiebacks due to hydrate or paraffin blockages. The discussion presented will address historical GoM blockages data, key existing and developing technologies that can be employed to provide reliable hydrate and paraffin management, and a listing of the technology gaps that currently exist for which solutions are still needed.
