港口国检查人员会把舱底水报警装置的数据与《油类记录簿》中的条目进行比对。如果相关数据不可用，检查人员可能会认定船舶存在缺陷。为了避免缺陷以及随之发生的延误，我们在此分享一项经验教训。
IMO指南规定，15 ppm舱底水报警装置应当记录日期、时间、报警状态以及15 ppm舱底水分离器的运行状态。记录装置还应存储数据至少十八个月，并且能够根据需要，显示或打印官方检查所要求的报告书。如果更换15 ppm舱底水报警装置，应有办法确保所记录的数据可留在船上使用18个月。

Flat Batteries May Erase Your MARPOL Data
Port State inspectors compare the Bilge Alarm data to the entries in the Oil Record Book and if that data is unavailable, inspectors may find the vessel deficient. We share a lesson learned to avoid deficiencies and consequent delay.
According to IMO guidelines, the 15 ppm Bilge Alarm should record date, time and alarm status, and operating status of the 15 ppm Bilge Separator. The recording device should also store data for at least eighteen months and should be able to display or print a protocol for official inspections as required. In the event the 15 ppm Bilge Alarm is replaced, means should be provided to ensure the data recorded remains available on board for 18 months.
