Abstract
An insertion shoe for retrofitting an undersea pipeline to permit passage therethrough of a scraper includes a plate sized to cover an opening in a branch connection of the pipeline and an inner surface structured to match the inner surface surrounding the opening. The insertion shoe can be installed in the branch connection to protect the opening without lifting the pipeline above water, so that the scraper may pass through without becoming jammed.
