Definitions
- the invention relates to a system for the mass recovery of petroleum products and derivatives escaping from a floating sheet on the sea following a maritime disaster either by sinking of an oil tanker or around a drilling site in sea as it was the case in Mexico at Ixtocl 1979.
- the system according to the invention solves all these problems. It includes a special vessel equipped with one or two of said systems, one at the front and the other at the rear, the vessel being able to move either in one direction or the other in the sheet to be recovered, preferably confined in a flexible dam.
- Each system is arranged so that the ship embarks, by wave effect on a ramp, the oil and water in a dynamic decanting bunker playing the role of water / oil separator. In this hold, the oil, of lower density than water, floats on its surface maintained at constant level by a pumping unit of adequate capacity. The oil slick thickens continuously in the settling bunker.
- a pumping assembly disposed in the vicinity of the underside of the sheet and benefiting from the gravitational pressure thereof, starts and discharges it, through 'a partition wall, in a storage bunker.
- the dynamic oil / water separator is maintained at a level such that oil and water can be loaded continuously while the ship is advancing in the slick at a maximum speed of about six knots, thanks to the permanent maintenance of '' an adequate level of reception by means of a set of centrifugal pumps expelling the water outside while maintaining the upper level of the aquifer under the conditions required to continue loading oil and water.
- a maximum mass recovery yield can be obtained by skimming the oil slicks, preferably confined in a flexible dam equipped with a weighted skirt to avoid leakage from below by very heavy swells. It is in this case that it is advantageous that the vessel is equipped with a recovery system at the front and at the rear as well as two pairs of bow propellers at the front and at the aft so, at the end of the penetration stroke in the dam, to translate into the tablecloth, parallel to itself and its width, and to start in the opposite direction by skimming the tablecloth in its second dynamic decantation bunker, and so on until it is fully recovered.
- Figure 1 schematically shows an example, seen in section in elevation, of a ship equipped, at the front and at the rear, with a mass recovery system of oil in oil according to the invention
- Figure 2 shows schematically, in section view from above, an example of means of propulsion and maneuvering of the vessel fitted with the system according to the invention
- Figure 3 shows schematically, in section view from above, an example of arrangement of the pumping means of the settling bunkers
- Figure 4 shows schematically, in top view, an example of a ship equipped with the system according to the invention, in action in a sheet partially confined in a flexible dam;
- Figures 5 and 6 show schematically, seen in cross section and seen in elevation, an example of a flexible dam for confining the oil slick.
- the special vessel 1 for recovering the mass of oil in the form of a sheet shown in FIG. 1 comprises, at the front and at the rear, two dynamic settling tanks 2, 3 closed on the top by a wall 4, 5 and each separated by a wall 6, 7 of a storage bunker
- the vessel 1 is specially designed to move rapidly at maximum speed on the high seas at around twenty knots to approach the oil slick to be recovered, whether or not previously surrounded by a containment dam comprising means preventing oil leaks from below as described fig. 5 and 6.
- the recovery system comprises, at the front and at the rear, a static or articulated ramp 10, 11, plunging into the sea to a depth sufficient to take into account very strong swells and whose upper end 12 is integral with the dynamic settling bay 2, 3.
- the ramps 10, 11 are covered with a flexible and thin sheet glued, in a material promoting the sliding of petroleum products.
- the ship moving in the tablecloth up to a speed of about 6 knots, embarks by wave effect, via its active ramp 10 or 11 depending on the direction of its movement, on which the oil of the slick with water in the corresponding dynamic decantation bunker 2 or 3.
- This bunker 2, 3 acts as a static water-oil separator, in which the oil slick 13, of lower density than that of water 14 , thickens by floating on its surface 15.
- the level 16 of the top of the sheet 13 is always kept lower than the level 17 of the sea, by a pumping assembly 18 of adequate capacity consisting of two groups of three centrifugal pumps for example of 5000 m3 / h.
- a dynamic level control means triggers the setting en route of said pump 19.
- This set of pumps 19 then operate continuously as long as the lower level of the ply 13 is below the level required for their proper operation. They benefit from the gravitational pressure of the sheet and pushes it, through the partition wall 6, 7, into the storage bunker 8.
- FIG. 2 schematically shows a section of the submerged hull seen from above at the level of the propulsion and maneuvering means of the ship equipped, at the front and at the rear, with the system according to the invention. Its propulsion means 25, 26 with two pairs of faired propellers 27,
- FIG. 3 shows schematically, in section seen from above, an example of arrangement of the means for pumping the settling bunkers 2 and 3 of Figure 1.
- the transfer pumps 19 are mounted through the partition walls 6, 7 between the settling bunkers and the storage bunker 8.
- the two pump groups 18 are mounted against the corresponding walls of the ship to push the water out of so decantation utes by maintaining the level 16 of the oil table below that of the sea.
- the bunker 8 for storing the recovered and decanted oil is equipped with heating means, for example steam, to allow it to be transferred to a receiver anchored near the water table.
- FIG. 4 schematically shows, in top view, an example of a ship 1 equipped with the system according to the invention, in action in a sheet 40 partially confined in a flexible floating dam 41 towed by two ships 42, 43 preventing the sheet from drifting to the wind 44 so as to continue to receive and accumulate the oil escaping from the wrecked tanker.
- the vessel 1 equipped laterally with retractable flaps 45, 46, at the front and at the rear, deploys its front flaps by means of a hydraulic control and enters the sheet at a speed of 5 to 6 knots, up to near the dam where it stops having opened a channel 48 in the water table.
- FIGS. 5 and 6 schematically show, seen in cross section and seen in elevation, an example of a flexible dam for confining the oil slick of FIG. 4.
- This dam is made up of elements 50, 51, made of waterproof fabric and resistant to hydrocarbons, in the form of a string of low-pressure inflatable tubes, separated at 53, fixed together in a sealed manner and comprising, secured below also in a seawater tight manner, a flexible skirt 54 slightly pleated and weighted making it possible to follow all the movements of the dam while permanently maintaining its seal with the sea even with very large hollows. Ballasting, maintaining the vertical skirt, can be carried out by means of small weights 55, for example made of lead, fixed to the lower part of the skirt in a regular pitch.
- a traction and maneuvering cable 56 is provided, arranged in passers-by at the connection of the skirt on the tubes. This cable is secured to the dam at the location of the partitions 53 and from place to place on each element so as to prevent traction being effected on the dam, but only on the cable.
- the characteristics of a vessel according to the invention skimming at an average value of 5 knots are as follows: collection width of 15 meters; tablecloth thickness of 0.5 cm; corresponding skimming capacity of approximately 15,000 m3 per 24 hours; propulsion provided by two 4,000 kW diesel engines; maneuvers in the water table provided by four 2000 kw bow thrusters; storage capacity of decanted oil 6,000 tonnes; cruising speed 20 knots; skimming speed up to 6 knots.
