A vent arrangement for a flexible pipe body. The vent arrangement comprises a vent valve and an annular region flushing valve. The vent valve is arranged to couple to an annular region access port of a flexible pipe end fitting such that the vent valve can vent fluid from the pipe body annular region. The annular region flushing valve is in fluid communication with the vent valve and the annular region access port. The annular region flushing valve is arranged to inject fluid into the vent arrangement for flushing the vent valve, the annular region access port or the pipe body annular region. An end fitting incorporating the vent arrangement, a flexible pipe comprising the end fitting and a flexible pipe body coupled to the end fitting, and a method of manufacturing a flexible pipe are also disclosed.

Gas venting

Apparatus for providing a predetermined fluid in a void space () of an annulus () of a flexible pipe and a method for providing a predetermined fluid in a void space of an annulus are disclosed. The method comprises introducing a predetermined fluid into at least one fluid communication passageway (), e.g. an elongated conduit, in an annulus () of a flexible pipe and, via the passageway (), communicating the fluid into a void space () of the annulus at a plurality of axially spaced apart locations, e.g. via a plurality of spaced apart openings in the wall of the elongated conduit, and at a pressure of less than about around 80 psi.
