Abstract
A method of laying conduit at sea from a reel vessel includes the steps of laying conduit, for example pipeline or umbilical, from a first reel which rotates about a first substantially vertical axis. Conduit is laid from a second reel of conduit rotating about a second substantially vertical axis spaced apart from the first axis. A portion of the route travelled by the conduit during the step of laying conduit from the first reel of conduit is substantially the same as a portion of the route travelled by the conduit during the step of laying conduit from the second reel of conduit, for example, the conduit from the second reel may pass around a part of the periphery of the first reel and then follow substantially the same path as previously travelled by the conduit laid from the first reel.
