<p>Method of protecting a flexible pipe (10) from corrosion comprising at least the steps of : (a) providing a flexible pipe (10) comprising: - an outer sheath (11); - an inner sheath (12) - an annular volume (16) bounded by the outer sheath (11) and the inner sheath (12) and comprising at least one metallic reinforcing layer (13, 15) and a dry annular void; - a pipe fluid passage (18), located within the inner sheath (12); - a first end (20) having a first end-fitting (40) comprising a first port (51) in fluid communication with the pipe fluid passage (18), and at least one protective liquid injection port (48) in fluid communication with the annular void; - a second end (30), having a second end-fitting comprising a second port in fluid communication with the pipe fluid passage (18), and at least one fluid release valve in fluid communication with the dry annular void; and (b) passing a protective liquid to the protective liquid injection port (48) of the first end-fitting (40), thereby filling the dry annular void within the annular volume (16) with protective liquid to provide a protected flexible pipe.</p> |
