Abstract

ABSTRACT

In engineering projects involving the construction of aboveground storage tank big enough to retain and/or accommodate large quantities of petroleum products such as crude oil and condensate, mathematical reduction of obtained field data using condition equation method is always appropriate for an onward monitoring of those structures. This paper demonstrates how condition equation method can be used to adjust geodetic surveying measurements in relation to aboveground storage tank. Accuracy is in the order of σa = 5.66e-4 and σb = 1.113e-3 while σsmax and σsmin are 0.0522 and -0.0511 respectively. The results obtained revealed that the method can be satisfactorily implemented for aboveground circular reservoir storage tank structural modelling and monitoring for a similar scenario.
