摘要
An unbonded flexible pipe for offshore transportation of fluids from a subsea facility. The unbonded flexible pipe has a length along a longitudinal center axis, and a first and a second end, and a first end fitting connected to the first end. The unbonded flexible pipe comprises from inside and out an electrically conductive carcass, an electrically insulating innermost sealing sheath, at least one electrically conductive armor layer comprising at least one helically wound electrically conductive wire and an electrically insulating outer sealing sheath. At least the electrically conductive layers are mechanically terminated in the first end fitting and the pipe comprises electrical connections arranged to apply a voltage over the electrically conductive layers which electrically conductive layers are electrically connected at a distance along the length of the unbonded flexible pipe from the first end fitting of the unbonded flexible pipe to provide an electric circuit. Also an offshore system comprising such unbounded flexible pipe is described.
