An external sheath (115) encloses an outer part of the flexible pipe, where a flexible ring (120) for wiping the flexible pipe is provided between the external sheath and the flexible pipe. A telescopic arm carries the external sheath, where the deployment of the telescopic arm causes the retraction of the flexible pipe inside the external sheath. The flexible ring is made of an absorbent material.</p> |
