摘要：
A Floating Production, Storage and Offloading (FPSO) surveillance system (7) is equipped with an adjustable alarm threshold that suppresses nuisance alarms if liquid level variations in FPSO crude oil and/or other liquid storage tanks (6) monitored by the system do not exceed estimated oscillating liquid level variations due to oscillating motions of the FPSO unit (1) during severe weather conditions.
