A seismic survey vessel (10) having a displacement monohull is provided with a streamer deck (20) whose width increases progressively from amidships (16) towards the stern (18) of the vessel, on both sides of the centreline of the vessel. This increased width of the streamer deck (20), reaching 37.5 metres at the stern, facilitates the deployment and towing of particularly wide streamer arrays, containing as many as sixteen streamers (28). It also provides space for the installation of novel streamer handling systems (22, 30, 32), one for each streamer, across the width of the rear of the streamer deck.
On décrit un navire hydrographique de relevé sismique (10) comprenant un monocoque à tirant d'eau. Ledit navire est muni d'un pont à flûtes sismiques (20) dont la largeur augmente progressivement du milieu du navire (16) à l'arrière (18) du navire, de part et d'autre de la ligne médiane de ce dernier. Cette augmentation en largeur du pont à flûtes sismiques (20), qui atteint 37,5 mètres à l'arrière, facilite le déploiement et le remorquage de stations complexes particulièrement larges pouvant contenir jusqu'à seize flûtes sismiques (28). Elle offre également de l'espace pour l'installation de nouveaux systèmes de manutention des flûtes sismiques (22, 30, 32), un pour chaque flûte, disposés en largeur à l'arrière du pont.
