OSTI ID:6285427
A method for laying a substantially continuous length of pipe on the sea bottom from a carrier vessel is described. The method consists of which a pipe carrying reel rotatably mounted on the carrier vessel, pipe straightening means mounted to the carrier vessel downstream of the reel in the direction of unspooling for movement in a direction substantially parallel to the rotational axis of the reel, and pipe guide means mounted to the carrier vessel downstream of the straightener means in the direction of pipe unspooling for movement in a direction substantially parallel to the rotational axis of the reel, wherein the method comprises the steps of rotating the reel in a direction to unspool the pipe and maintain a substantially constant dynamic braking force on the reel to maintain tension on the pipe as it is unspooled.
