s are supposed to match, but this is difficult as measurements, particularly of liquids in storage tanks on ship at sea, are rough estimates at best. There are other, more basic problems, though. For many years, governments and ship operators only paid lip service to OWS operation and oil record book entries. Waste oil was routinely dis- charged at sea and few seemed to care. Chief engineers were under constant pressure to keep operating costs down. One method utilized was to ignore maintenance of the OWS. When the OWS wasn' working properly or when the filter needed replacing, the system would be circumvented. This could be done either through use of by-pass hose to divert the discharge around the sensor unit or by adding non-oily flush water to artificially reduce the level of oil passing the sensor unit to below 1 ppm. Alternatively, false entries could be made in the oil record book to show that more waste oil was burned on board than was actually the case. It is difficult to falsify the amount of waste oil trans- ferred ashore, since signed receipts (and payment records) are required. As long as everyone played by the same rules, the system (while flawed) was stable. Everything changed on February 1, 1, when routine .. Coast Guard air patrol observed long sheen of oil streaming astern of cruise ship on the high seas off Florida. Review of the ship' oil record book when the ship arrived in port revealed that no entry had been made relative to this discharge. When the flag state declined to take action, the .. government charged with cruise ship operator with making false statement to federal official. The cruise ship operator litigated this and related case, arguing, among other things, that there was no violation of federal l
