OIL AND OIL PRODUCT SPILLS ON THE WATER SURFACE DETECTION AND MONITORING DEVICES UNDER ACTUAL CONDITIONS TESTING METHOD AND THE METHOD IMPLEMENTATION SYSTEM Russian patent published in 2018 - IPC G01D21/00 

FIELD: testing equipment.

SUBSTANCE: invention is intended for the oil and oil product spills on the water surface detection and monitoring devices testing under actual conditions. Essence: measuring the instruments parameters before and after the impact with their readings subsequent recording and processing. At that, first, on the water surface created the bounded along the perimeter space (8), into which the film-forming substance (9) is placed, imitating the oil and oil products spill. Wherein as the film-forming substance, an environmentally safe substitute is used, which minimum layer thickness is determined by the device under test (7) sensitivity, and the layer maximum thickness corresponds to the smallest volume of oil and oil products in the created limited space, which the tested device registers. Tested device is placed above the limited space at a height of 2–3 m (L), with its subsequent levelling above the water surface. Recording the environmental conditions at different times of the day and under different weather conditions. After the measurements stabilization, recording the tested device readings along with information on the film-forming agent layer thickness. In the absence of the tested device readings, adding the film-forming substance metered additional amount into the limited along the perimeter space. Repeating the operation until the device corresponding readings appearance. Based on the recorded data analysis, evaluating the tested device qualitative characteristics. This method implementation system consists of the tested instruments unit (1), oil and oil product spill imitation unit (2), signals receiving unit (3), analyzer unit (4), personal computer (5), film-forming substance supply unit (6).

EFFECT: increase in the devices testing reliability due to the external factors conditions maximum proximity to the devices operation natural conditions.
