摘要
The invention relates to a method for taking a sample (14') from a flexible pipe (10), wherein the flexible pipe (10) comprises an anti-collapse layer (12) forming an inner wall surrounding an inner space (9) of the flexible pipe (10), and at least one liner layer (14) surrounding the anti-collapse layer (12). The method comprises: - providing access to the liner layer (12) by making a hole (99) extending from the inner space (9) of the flexible pipe (10) through the anti-collapse layer (12) into the liner layer (14), and taking the sample (14') from the liner layer (14) for allowing analysis of the level of degradation of the sample (14') in a laboratory. The invention further relates to a tool for use in such method. The invention allows for sample collection while leaving the flexible pipe in place and fully intact.
