Description

The invention relates to shipbuilding, in particular, to oil gathering vessels.

Known oil gathering vessels, including side barriers installed obliquely to the side of the vessel

A catamaran vessel for collecting oil from a water surface is known, comprising hulls, oil receiving tanks, boom barriers located between the hulls and connected to two sides with closed circuits with drive gears mounted at the sides

A disadvantage of the known vessel is the inability to have high oil collection performance (trawl speed) at the optimum sight of metal consumption and seaworthiness of the ratio of the main dimensions. The vessel with the optimal ratio of the main dimensions, in

In particular, length and width, the rate of oil filling is forced to decrease so that the oil has time to concentrate at the side with the certain speed (below the critical) of two adjacent boom sections from the bow to the stern

The purpose of the invention is to increase the efficiency of the vessel

This goal is achieved in that the catamaran vessel for collecting oil from the surface of the Veda, containing hulls, tanks for receiving oil, booms located between the hulls and connected to the yard (yurts with closed chains with drive gears, ismotiravan - an oil receiver at the sides, equipped with an additional oil receiver and an additional boom barrier

In this case, the boom barriers form a V-shaped plan and the oil receivers are located respectively on each catamaran body and are located in its aft part. At the same time, the tops of the boom branches connected to the lower branches of the corresponding endless chains are turned towards the nasal tip of the catamaran.

By means of V-shaped booms, the oil flow between the hulls is divided into two parts, which allows to reduce the time of the concentration of oil stains located between the adjacent sections of the booms moving from bow to stern. -This, in turn, allows to accelerate the trawling of oil or optimize the dimensions of the vessel, because while accelerating the trawling of oil and the corresponding acceleration of the movement of the booms relative to the vessel, the oil manages to concentrate in the ducts at the sides during the movement of two adjacent branches of the booms from bow to stern.

Figure 1 shows an oil recovery vessel, top view; figure 2 is a section aa in figure 1; in Fig.Z - section bB in Fig.1; FIG. 4 is a cross-section BB in FIG. 1: in Fig. 5, the assembly in Fig. 4; in Fig.6 is a view of G in Fig. B; Fig. 7 shows a boom storage device (in the stowed position), top view; Fig.8 is a section DD in Fig.7.

The catamaran oil collection vessel consists of a left hull 1 and a right hull 2 containing oil receiving tanks 3. Between the hulls 1 and 2, the booms 4 are arranged symmetrically with respect to the vessel’s plane, forming a V-shape in plan view, made, for example, in truss structures made of aluminum-magimeic alloy or three-layer fiberglass. Booms 4 are connected to the two sides with closed chains 5 by means of a lock connection, including profiled plates 6 and 7, mounted on chains 5 and booms 4, clamp 8, respectively. Chains 5 are passed through the gears in the fore and aft ends 9 with drives (not shown) housed in buildings 1 and 2.

The tops of the branches of the booms 4. connected to the lower branches of the respective chains 5 are turned towards the bow of the vessel.

At the ends and at the tops of the booms 4 are placed rollers 10 on the brackets 11.

On each hull of the vessel, in its aft part, there are oil receivers 12 connected via brackets to rollers 13 placed in vertical guides 14. The hulls 1 and 2 at the installation of the oil receivers 12 have cutouts 15 in the sides at the waterline level, communicating the oil compartments 16 buildings 1 and 2 with outboard space. Inside the oil 0 receiving compartments 16 there are oil pumping pipelines 17 connected through cargo pumps 18 to oil receiving tanks 3. At the aft end of the vessel there is a storage device for booms, including a support 19, a drive 20, a swing beam 21 of a box-shaped profile, open from below in the planes of the rollers 10,

0 The ship operates as follows. AT

in the stowed position, all branches of the booms A, through the rollers 10, are supported on the swinging beams 21 and collected in a bag above the waterline (Fig. 7), the oil receivers 12 are lifted out of the water.

Due to the movement of the chains 5, the plates 6 are combined on the chains 5 and the plates 7 on the extreme branches of the boom 4 in the packet, with the formation of booms

0 lock barriers. The movement of the plates 6 and 7 relative to each other is prevented by the latches 8. The operations are repeated for all branches of the boom bar 4.

5 Thus, the boom 4 is sequentially secured to the chains 5 at an equal distance from each other, determined by the position of the plates 6 on the chains 5. The pivot beams 21 are brought to the vertical position by the drive 20. Lowering along the guides 14 oil receivers to water 12.

Accepted ballast in tank 3 for the collected oil and non-reception compartments

5. 16 until the vessel reaches the working water line corresponding to the position of cutouts 15 in the sides of the hulls 1,2.

Oil film trawling is performed at high speed of the ship. Oil enters the space between hulls 1 and 2. The branches of the booms 4 are moved using chains 5, passed through gears 9 with drives, in the opposite direction to the vessel, at a speed lower than the vessel, creating an oil movement along the V-shaped booms obstacles 4 from the diametrical plane to the sides and to the stern of the vessel. The speed of movement of the booms is chosen so that it does not exceed the critical value, i.e.

the speed at which intensive entrainment of oil begins under the barrier. At the aft end, side barriers 4 exit the water and along the upper branches of chains 5 move to the bow of the vessel,

Using the V-shaped side barriers 4, the oil is divided into two streams, concentrating between the sides of the hulls 1, 2, booms 4, and moves to the stern of the vessel, where it is caught by the oil receivers 12 and sent through the cutouts 15 to the oil reception compartments 16 In order not to create a retaining pressure during the movement of oil, the oil receivers 12 can be made, for example, with horizontal plates mounted at the oil-water interface. From the oil receiving compartments 16, through pipelines 17, oil is pumped by cargo pumps 18 into an oil tank 3 on top of the ballast water, forcing it overboard, thereby keeping the draft of the vessel at the level of cutouts 15.

At the end of the oil trawling, the vessel is put into the stowed position in the sequence opposite to bringing it into working condition.

The use of the proposed vessel allows to increase the efficiency of oil collection, to optimize the characteristics of the vessel.
