Study on the multiparameter monitoring system in the old VLCC for offshore oil storage

In recent years, the global oil price fluctuated greatly, offshore oil storage in the VLCC has risen gradually in foreign countries, the case of VLCC offshore oil storage has not appeared in China. In order to improve China's oil reserve system, improve effectively the profit of the old VLCC, the actual VLCC was taken as the research object, relevant research were carried out in the paper. In consideration of the actual situation of the aging equipment in the old VLCC, high potential risk of offshore oil storage and the importance of the multi-parameter monitoring so on, the design requirements of the multi-parameter monitoring system in the old VLCC for offshore oil storage were analyzed, the multi-parameter monitoring system in the old VLCC was structured by use of the software Python, the error of the monitoring system data was tested. The results shown that the errors of oxygen content and gas pressure in the multi-parameter monitoring system in the old VLCC developed were less than 2%, and the accuracy rate was more than 98%. So the multi-parameter monitoring system in the old VLCC for offshore oil storage is feasible and can provide a good guarantee for the offshore oil storage in the old VLCC.
