Abstract

Device for increasing the thickness of an oil slick between the floats of two catamarans towed by an oil tanker. The stern of an oil tanker 1 drives the seawater-oil mixture between the floats of two catamarans (port and starboard) 2, by means of flexible deflectors 3 having rigid reinforcement which is welded to the hull. Each catamaran is provided with a device consisting of vertical partitions 4 which are perpendicular to the current and which progressively sink deeper below the water level. These vertical partitions rake the seawater-oil current. Under the combined effect of this movement and of buoyancy, the oil moves up and successively fills each section 5, 6, 7, 8, (reaching a depth of 2 metres in the last one 8).

Description

La présente invention décrit un dispositif permettant d'augmenter, entre les deux flotteurs d'un catamaran, l'épaisseur d'une nappe de pétrole dérivant sur la mer, rendant possible son pompage
Entre ses deux flotteurs, le catamaran est équipé de panneaux fixes ressemblant à une échelle d'escabeau posée à plat sur l'eau.The present invention describes a device making it possible to increase, between the two floats of a catamaran, the thickness of an oil slick drifting on the sea, making it possible to pump it
Between its two floats, the catamaran is fitted with fixed panels resembling a step ladder placed flat on the water.

Si on fait référence à cette comparaison, on peut écrire ce qui suit i
- les montants de cette échelle sont ici deux panneaux verticaux s'enfonçant progressivement dans l'eau jusqu'à 2,50 mètres sous la ligne de flottaison.If we refer to this comparison, we can write the following i
- the uprights of this ladder are here two vertical panels sinking gradually into the water up to 2.50 meters below the waterline.

- les marches de cette échelle sont ici des panneaux verticaux de hauteurs différentes (4). - the steps of this ladder are here vertical panels of different heights (4).

. le ler panneau descend 40 cm sous la flottaison
. le 2me panneau descend 80 cm sous la flottaison
. le 5me panneau descend 200 cm sous la flottaison.. the 1st panel descends 40 cm below the waterline
. the 2nd panel descends 80 cm below the waterline
. the 5th panel descends 200 cm below the waterline.

Les deux catamarans équipés de ce dispositif, sont remorqués sur chacun des flancs d'un pétrolier. The two catamarans equipped with this device are towed on each side of an oil tanker.

L'étrave du pétrolier (1) en s'engageant dans la nappe de pétrole, repousse sur chacun des flancs du navire un courant où se mélangent l'eau de rner et le pétrole. The bow of the oil tanker (1) by engaging in the oil slick, pushes on each of the sides of the ship a current where the water and the oil mix.

Ce courant est capté entre les deux flotteurs du catamaran et s'engage entre les deux panneaux verticaux. This current is captured between the two floats of the catamaran and engages between the two vertical panels.

I1 y a d'abord une accumulation de pétrole devant le premier panneau transversal (4) d'où t augmentation progressive de l'épaisseur de la nappe. There is first of all an accumulation of oil in front of the first transverse panel (4) whence t a progressive increase in the thickness of the sheet.

Quand l'épaisseur de la nappe atteint 40 cm, le pétrole passe sous le premier panneau et commence à remplir le premier compartiment. When the thickness of the tablecloth reaches 40 cm, the oil passes under the first panel and begins to fill the first compartment.

quand le premier compartiment est rempli, 11 épaisseur de la nappe continue à augmenter et atteint 80 cm : le passage dans le deuxième compartiment est possible. when the first compartment is filled, the thickness of the sheet continues to increase and reaches 80 cm: passage into the second compartment is possible.

Le procédé se répète jusqu'au remplissage de tous les compartiments. The process is repeated until all the compartments have been filled.

L'épaisseur de la couche dans les différents compartiments permet le pompage du pétrole. The thickness of the layer in the different compartments allows the pumping of oil.

Le passage du mélange eau de mer-pétrole de l'étrave du pétrolier à l'espace compris entre les flotteurs de chaque catamaran est assure par un déflecteur souple fixé sur un bat i rigide soudé à la ooque du pétrolier.  The passage of the seawater-oil mixture from the bow of the oil tanker to the space between the floats of each catamaran is ensured by a flexible deflector fixed on a rigid bat i welded to the tanker's shell.

Avantages de ce dispositif :
La nappe de pétrole est traitée sur une largeur égale à celle du pétrolier et de ses deux catamarans : soit une largeur de 35 à 40 mètres.Advantages of this device:
The oil slick is treated over a width equal to that of the oil tanker and its two catamarans: a width of 35 to 40 meters.

Ce traitement se fait à la vitesse de déplacement du pétrolier (3 à 4 noeuds). This treatment is done at the speed of movement of the tanker (3 to 4 knots).

Ces catamaransne présentant aucune pièce mobile, il est possible d'envisager leur construction sous forme de modules en alliage léger qu'il est possible de transporter par avion et d'assembler en quelques heures. These catamarans have no moving parts, it is possible to envisage their construction in the form of light alloy modules which can be transported by plane and assembled in a few hours.

Suivant la façon dont cette idée est réalisée, il est possible de transformer en quelques heures, n'importe quel pétrolier, où qu'il soit, en navire de traitement des nappes de pétrole dérivant en mer.  Depending on how this idea is realized, it is possible to transform in a few hours, any tanker, wherever it is, into a processing vessel for oil slicks drifting at sea.
