In 2020, with the unit still producing a crude oil storage tank on the Bumi Armada owned and operated Armada Kraken FPSO was successfully inspected by Texo using a UAVS flown from outside the tank. This type of truly remote survey significantly reduces the risk to personnel, the survey time and the survey cost, whilst maintaining a survey standard that is close to that achieved by personnel entering the tank and utilising scaffolding. Lessons learnt in the following areas are discussed: • Detailed Scope of Work value, including potential & actual anomaly handling. • Careful pre-mobilisation briefing of the project team and Class surveyor. • Engagement with Bumi Armada personnel, onshore and offshore, and the Texo project team. • Engagement with DNVGL to enable the inspection to be Verification & Class credited. • Development by Texo of project specific procedures based on onshore trials. • Tank cleanliness and cleaning.

Oil is a kind of important chemical raw materials, countries have put oil as an important sources of energy and actively expanded its strategic oil reserve along with our country energy strategy adjustment. The number of oil storage increases constantly, the tank farm scale expands unceasingly and fire accident of oil storage tank rises constantly. So it is an important measure for preventing the oil tank fire to analyze reason of oil tank fire and adopt corresponding fire prevention countermeasures.

In order to realize functions of automatic monitoring, alarming and extinguishment on fire in crude oil storage tank, the paper came up with a fire detection model with multisensor, including selective module with fire feature combination, supervised training module and fire detection module. By regarding PNN as a classifier to carry out tests on effectiveness of the model, the conclusions that the model can reduce the influence of fire parameters’ fluctuation on detection results was drew. Moreover, an excellent fault-tolerant ability was possessed at the same time. Through some confirmatory experiments, The phenomenon was reached that two kinds of parameters in adoptive four parameters have no normal fire signal, but the model still can greatly distinguish from correct fire state.

Oil Storage Tank

As an important production facility, storage tank plays a more and more important role in the storage and transportation of crude oil and chemical product. The remaining life prediction of storage tank is to forecast the thinning trend of plate thickness, and forecast remaining life on the premise that remaining strength of storage tank meets the tank operation and safety requirements. Maximum corrosion depths of tank bottom plate obey the maximum extreme value distribution. Based on maximum extreme value distribution and statistics of corrosion data, the calculation formula of the remaining life prediction for large-scale crude oil storage tank was obtained by formula derivation. Compared with API STD 653 and EEMUA 159, the inspection interval specified by China standard SY/T 5921 is relatively conservative. The remaining life of a certain crude oil storage tank (tank A) in china is determined by the remaining life of tank bottom plate. The remaining life of tank A at the reliability of 0.99, 0.999 and 0.9999 are 25 years, 20 years and 17 years, respectively. For the acceptable failure probability of 1×10−4, the inspection interval of tank A can be extended from required 5–7 years specified by China standard SY/T 5921 to 17 years. The remaining life of crude oil storage tank predicted by the method proposed in this paper can be used as an important reference in the determination of inspection interval and tank’s maintenance.
