METHOD AND VESSEL FOR COLLECTION OF OIL FROM THE SEA

摘要

Collecting oil on large sea areas occurs by means of a supertanker which is provided with externally added loading boxes (2), the outer walls (10, 22) of which having a horizontal slot (26) which enables an inflow of the oil contaminated water layer, which falls down into the loading box (2), and which from its bottom area is led through holes (14) in the ship side for further drop into a collecting tank (38). This tank is connected with other tanks (42, 44) separating off the water which has been taken in together with the oil, and the thus separated water is pumped back to the sea whereby the ship can collect a large useful load of oil with low water content. It is directly provided that together with the oil layer there is loaded a large amount of water as this determines an oil influx with great capacity. The intake slot (26) is designed in a wall part (10, 22) which is automatically vertically movable in dependence of a measurement of the sea level position relative to the ship such that the slot (26) is always at level with the oil-contaminated layer, both by the generally increasing draught of the ship in the sea and by occurring wave movements in the water.
