Abstract:
An oil containment system aboard a vessel which includes a pneumatic system to provide power to a winch and reel assembly containing boom whereby the pneumatic supply is capable of simultaneously powering the winch-reel assembly for boom deployment through inflatable gas fed to a pneumatic motor while also inflating the boom. The inflation of the boom is accomplished by diverting, all or any portion thereof, the inflatable gas from a pneumatic supply through a hose that runs concurrently on the outside of the boom wherein appropriate rates of inflatable gas pressure are allowed to flow through the hose to feed through a valve and hose assembly that connects the inflatable gas supply of the hose to the inflatable gas containment system of the boom. The pneumatic supply originates from a single pneumatic system powering both the winch and reel assembly as well as associated brake and feeding inflatable gas pressure to the inflation hose running concurrently with the boom. The system may be manufactured in a form such that it is compact enough to be installed in, or rapidly transported to, any area or place or vessel where there is likelihood of a discharge of floating material, such as hydrocarbons, floating on a liquid surface. The present invention may also be operated through the use of pneumatic control without the benefit of electric power making it particularly useful for applications in remote areas or during a disaster when electrical power is not readily available.
Abstract:
The invention relates to a method for collecting oil from waters (3), in which method a vessel (1) is driven to an oil-polluted location. An oil boom (6) is arranged into the water (3) so that its first fixing point (6a) is in connection with the vessel (1) and the second fixing point (6b) is at a distance from the vessel. Water to be cleaned (32, 33) is steered to the vessel with the aid of the oil boom (6). Oil (2) is collected with a cleaning apparatus (13) from the water (30, 32, 33), which was steered to the vessel. In the method the vessel (1) is fixed substantially in its place in relation to the bottom of the waters. A propulsion equipment (12) arranged in connection with the vessel is used so that it moves the water (3, 30, 32, 33, 34) around the vessel in relation to the vessel (1) and the oil boom (6, 15), which are fixed in their place. The invention also relates to an oil combatting vessel (1), which comprises at least a hull, a propulsion equipment (12) and a cleaning apparatus (13) for separating the oil from the water (3), and at least two fixing means (10, 10') for fixing the vessel to the bottom of the waters (3), of which fixing means the distance between the two fixing means is at least 10 percent of the length of the vessel (1).
Abstract:
The invention relates to an oil boom including two adjacent and elongated floats (1) extending for the length of the boom; frameworks (2) that are transversal to the oil boom to support the floats to one another; and an oil-impermeable vertical wall (3). According to the invention, both floats (1) are air-filled tubes operating in an accordion-type fashion and are disposed on the same side of the vertical wall (3), and the vertical wall is supported to projections (4) extending from the frameworks (2).

Abstract:
A method to utilize an ice-breaker (10) in a novel way such that tanks of the anti-roll system and/or tanks (21, 22, 23 and 24) of the heeling system are used for recovering and/or processing oil (16) to be recovered from water. The oil is separated from water in a tank of the anti-roll system and/or a tank (21) of the heeling system of the ice-breaker, which tank contains warm water (15) and steam heat pipes (19). The tanks of the anti-roll system and/or tanks of the heeling system of the ice-breaker have separate oil recovery piping which is used when the heeling tanks of the ice-breaker are used for responding to an oil spill.
Abstract:
The invention relates to an oil collecting apparatus and to a corresponding method for collecting oil from the surface of water. The oil collecting apparatus comprises a set of oil booms (3) coupled to form a long line of oil booms. According to the invention, the line of oil booms comprises, at a distance from each other, a number of anchorage points (4) for anchoring the oil boom (3) onto the sea bed and, in addition, between the anchorage points and in conjunction with the oil boom there is an oil collecting station (5) for collecting the oil directed by the booms from the surface of water.
Abstract:
Destinado a acoplarse al casco de una embarcación, en cada uno de los laterales del mismo y en las proximidades de su proa, consiste en un brazo (1) materializado en una carcasa (8) de configuración tendente al semicilindro, en cuyo seno se aloja un husillo (10) que tiende a desplazar el crudo hacia el casco de la embarcación, carcasa rigidizada mediante una pluralidad de cartelas posteriores (13) y que resulta abierta hacia delante y hacia arriba, contando el brazo en su extremidad libre con un flotador (21) y rematándose por su extremidad interna en un depósito colector (3) en el que descarga el husillo (10), donde se establece un mecanismo (22) de transmisión motriz a dicho husillo, desde el seno de la embarcación, así como un tubo conectado a una bomba de aspiración también establecida en la embarcación. De esta manera en el avance de la embarcación el crudo accede al interior de la carcasa (8) y en el seno de la misma es desplazado longitudinalmente hacia el depósito (3), desde el que es aspirado hacia el interior del barco.

PCT No. PCT/IT90/00063 Sec. 371 Date Jun. 27, 1991 Sec. 102(e) Date Jun. 27, 1991 PCT Filed Jul. 10, 1990 PCT Pub. No. WO91/01410 PCT Pub. Date Feb. 7, 1991.The apparatus has two portions wherein the first conveying portion functions to deflect and concentrate a large strip of the surface floating pollutant to be recovered, towards a narrower throat or exit section, and the second recovery portion effects the mechanical recovery of the pollutant thickened layer flowing through the throat of the first portion. The conveying portion includes a vessel itself with two floating arms symmetrically set in a "V" shape aft the vessel on its two sides, with their entrance section positioned just back the midship section of the vessel, while the throat or exit section is placed aft the vessel. The recovery portion of this equipment is a self-floating apparatus positioned immediately on the back of the throat of the conveying portion, and is towed by the vessel by means of a swinging fork. The recovery portion has a floating body which surrounds and delimits laterally, along three perpendicular sides, an inner chamber which has its bottom closed by a bottom wall and its front side defined by a cylindrical, horizontal drum rotated by an engine.
