SYSTEM FOR DETECTING AND RECORDING DISCHARGES OF WASTE HYDROCARBONS OF A SHIP

摘要

The system is meant to detect and record in real time any irregular dumping occurring during the operation of any ship, both of waste hydrocarbons stored in the bilge (1) of the ship and of residues from cleaning the crude oil tanks of oil tankers. The system is based on providing two level probes (13-14) to detect the upper level of the layer of waste hydrocarbons (3) and its bottom layer, which floats on a volume of waste water (2) contained in the bilge (1), as well as optionally a third probe (16) may be provided in a tank (10) for storage of waste hydrocarbons separated from the waste water, so that the data obtained from these probes are recorded and stored by a multiparameter recording station (15) which, in combination with a computer system of the port allows to know the variation in volume of waste hydrocarbons during the operation of any ship. Oil tankers are provided with a flow meter (18) in the pipe (19), which detects the data corresponding to residues obtained from cleaning the tanks (17) (see Figure 2), with the data obtained by this flow meter being sent to the same recording station (15) in order to know the variations in volume of these residues. <IMAGE>
