In no case should the response time, including the response time of the oil content meter, be more than 40 seconds.\n\n(7) The location of sampling probes in relation to any point of flow diversion to a slop tank must be selected with regard to the need for sampling the oily water in the recirculation mode.\n\n(8) The arrangements for driving the sampling pump or any other pumps used in the system must account for the safety requirements of the space in which the pump is located. Any bulkhead penetration between a hazardous and a non-hazardous area must be of a design meeting the requirements of 46 CFR 32.60-20 and 46 CFR subpart 111.105.\n\n(9) The flushing arrangement must be such that where necessary it can be utilized for test-running and stabilizing the oil content meter and correcting for zero setting.\n\n(10) Sample water returning to the slop tank must not be allowed to free-fall into the tank.

(1) A flow meter for measuring the rate of discharge must be installed in a vertical section of a discharge line or in any other section of a discharge line as appropriate, so as to be always filled with the liquid being discharged.\n\n(2) A flow meter must employ an operating principle which is suitable for shipboard use and, where relevant, can be used in large diameter pipes.\n\n(3) A flow meter must be suitable for the full range of flow rates that may be encountered during normal operation. Alternatively, arrangements such as the use of two flow meters of different ranges or a restriction of the operational flow rate range may be employed if necessary to meet this requirement.\n\n(4) The flow meter, as installed, must have an accuracy of \u00b110 percent, or better, of the instantaneous rate of discharge throughout the operating range for discharging the effluent.\n\n(5) Any component part of the flow meter in contact with the effluent should be of corrosion-resistant and oil-resistant material of adequate strength.\n\n(6) The design of the flow metering arrangements must account for the safety requirements of the space in which such metering arrangements are located.\n\n(d)  Ship's speed indicating system.  The automatic speed signal required for a monitoring system must be obtained from the ship's speed indicating device by means of a repeater signal. The speed information used may be either speed over the ground or speed through the water, depending upon the speed measuring equipment installed on board.\n\nSee \u201cRecommendation on Performance Standards for Devices to Indicate Speed and Distance,\u201d Annex to resolution A.824(19) as amended by resolution MSC.96(72).\n\n(e)  Ship position indicating device.  The ship position indicating device must consist of a receiver for a global navigation satellite system, a terrestrial radio navigation system, or other means suitable for use at all times throughout the intended voyage to establish and update the ship's position by automatic means.\n\n(f)  Overboard discharge control management.  The overboard discharge control must be able to stop the discharge of the effluent into the sea automatically by either closing all relevant overboard discharge valves or stopping all relevant pumps. The discharge control arrangement must be fail-safe so that all effluent discharge is stopped when the monitoring system is not in operation, at alarm conditions, or when the monitoring system fails to function.\n\n(g)  Processor and transmitting device.  (1) The processor of a control section must receive signals from the oil content meter, the flow rate indicating system and the ship's speed indicating system at time intervals not exceeding 5 seconds and must automatically compute the following:\n\n(i) Instantaneous rate of discharge of oil in liters per nautical mile; and\n\n(ii) Total quantity of oil discharged during the voyage in cubic meters or liters.\n\n(2) When the limits imposed by \u00a7 157.37(a)(3) and (4) are exceeded, the processor must provide alarms and provide command signals to the overboard discharge control arrangement, which will cause the discharge of effluent into the sea to stop.\n\n(3) The processor must normally include a device for the continuous generation of time and date information. Alternative arrangements that ensure the automatic and continuous reception of time and date information from an external source may be approved by the Marine Safety Center.\n\n(4) In the event of power failure the processor must retain its memory in respect to computation of the total quantity of oil discharged, time, and date. A printout of data must be obtained when the monitoring system is operating with manual override, but the printout of data is not required if, when the power fails, the monitoring system activates the overboard discharge control to stop the discharge of effluent.\n\n(h)  Recording devices.
