Disclosed is an apparatus for use in handling an elongate member, comprising a support line extending between first and second points; a first winch mechanism at the first point for paying out and recovering the support line; a first wrapping device at the first point for rotating one of the elongate member and the support line around the other as they are paid out to wrap the two together, and to unwrap them from one another as they are recovered; a second winch mechanism at the second point, for recovering and paying out the support line; and a second wrapping device at the second point for rotating one of the elongate member and the support line around the other to unwrap them from the one another as they are recovered, and to wrap them together as they are paid out. Also disclosed is a method of handling an elongate member between first and second points that are spaced apart from one other, comprising: paying out a support line between the two points; paying out an elongate member between the two points; wrapping one of the support line and the elongate member around the other as they are being paid out from the first point; unwrapping the support line and the elongate member from one another as they are recovered at the second point. The apparatus and method are useful in raising and lowering a load, towing, and handling service cables, tubes, pipes, hoses or other elongate lines that are connected between two points. A preferred embodiment is described for the subsea deployment of wireline and the deployment of signal and power cables to subsea wells.
