| Description |
When a subsea pipeline
reaches the end of its useful life, it must be abandoned or removed.
Currently, subsea pipelines are de-inventoried and purged until the
hydrocarbon levels are undetectable before abandoning them in place or the
pipeline is de-inventoried and purged until the hydrocarbon levels are
undetectable before recovering the pipe as scrap. The common practice in
both the U.S. waters and the North Sea is to abandon the pipeline in place
which, for this study, was used as a baseline for comparison against other
removal options currently used around the world.
The attached report
presents an overview of the current U.S. and International regulations and
details the safety risks, environmental risks and costs associated with the
various disposal options for pipelines.
