Title (EN) METHOD OF LAYING OFFSHORE PIPELINE FROM A REEL CARRYING VESSEL
(FR) PROCEDE DE POSE D'UNE CANALISATION AU LARGE A PARTIR D'UN BATEAU PORTANT UNE BOBINE
Abstract: front page image
(EN)Methods and techniques related to the control of pipelaying operation from a self-propelled reel pipelaying vessel (10). The methods are concerned with 1) controlling pipeline geometry as a function of pipe (p) entry angle into the water and tension on the pipeline; 2) monitoring the excursion of the pipeline outside certain defined limits and controlling the pipeline geometry based on such measured excursions; and 3) compensating for pipeline induced turning moments which would otherwise tend to draw the pipelaying vessel (10) off course and off the predetermined pipeline right of way.
(FR)Procedes et techniques se rapportant aux operations de pose de conduites a partir d'un bateau autopropulse (10) de pose de conduites enroulees autour d'une bobine. Les procedes concernent 1) la commande de la geometrie de la conduite en fonction de l'angle d'entree de celle-ci (p) dans l'eau et de la tension de la conduite; 2) le controle de la trajectoire de la conduite a l'exterieur de certaines limites definies et la commande de la geometrie de la conduite en se basant sur de telles trajectoires mesurees; et 3) la compensation de moments induits par la conduite qui, autrement, aurait tendance a faire devier le bateau de pose (10) de sa route et ecarter la conduite de son trace predetermine.
