Recalde, C E

A method is claimed of converting a single pipeline laying vessel having a main storage reel and a privotal ramp pipe straightening and tensioning assembly to a multi-reel pipe laying vessel for the layout of an operational lines array within which a rigid walled pipeline is contained. The method is described comprising the steps of: removing the pivotal support ramp and pipe straightening and tensioning equipment from the deck of the vessel; installing at least one auxiliary operational lines storage reel on the vessel in the upspooling direction of the pipeline stored on the main reel; installing an operational lines laying device adjacent the stern of the vessel, the laying device including operational lines supporting means adapted for providing moving contact for each of a plurality of operational lines and the means interconnected and adapted for moving the operational lines at a common velocity for permitting layout from the vessel in a downward juxtaposed configuration; and providing the main reel and the auxiliary reels with motive power means having both spooling direction power and unspooling direction braking systems.
