Development of a Sonar Oil Tanker Cargo Measurement System

摘要

A Sonar Oil Thickness Sensor (SOTS) device designed to measure the thickness of oil spilled onto the sea was investigated for adaptation to an oil tanker cargo measurement system. The SOTS-T (oil tanker configuration) utilizes the SOTS operational features of microprocessor control and time gated sampling window, to locate and measure oil/air and water/oil interfaces in cargo tanks and a variety of other oil tanker measurement situations. The SOTS-T was determined to be feasible for: cargo load level gauging within custody transfer accuracy; operation within a 'closed ullage' environment; and pollution control monitoring required by IMCO. The SOTS-T configuration was integrated into a cargo measurement system, and incorporated all of the required measurement functions. (Author)
