Design and control of pig operations through pipelines

Chatter vibration phenomenon of pipeline inspection gauges (PIGs) in natural gas pipeline

“…Although, the motion of M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT the PIG has been extensively studied and reported in literature, a majority of the experimental and theoretical work have been focused on exploring pigging motion (Nieckele,A.O. et al, 2001;Tolmasquim, S.T., Nieckele, A.O., 2008;Podgorbunskikh, A.M.et al, 2007;Zhu, X.et al, 2014).…”

Modelling and Simulation of Free Floating Pig for Different Pipeline Inclination Angles

“…Xu & Gong [6] developed a simplified pigging model for predicting the pigging operation in gas condensate horizontal pipelines and compared with simulation result from OLGA software. Tolmasquim and Nieckele [7] developed simulation model to assist in the control and design of pig operations through pipelines and predict the process variables. Esmaeilzadeh et al [8] the pig in gas and liquid pipelines to predict the pig position, pig velocity, upstream optimum flow rate, and time to reach its destination.…”

Numerical simulation of contact force on bi-directional pig in gas pipeline: At the early stage of pigging

“…Estimating the frictional force and the required driving pressure often involves guesswork and consequently, a high degree of uncertainty (Aevedo et al, 1996;Nieckele et al, 2001;Esmaeilzadeh et al, 2006;Esmaeilzadeh et al, 2009). Tolmasquim and Nieckele (2008) classified the contact force on the pig into the static force (when the pig is not in motion) and the dynamic force (when the pig is moving). The dynamic force (dynamic frictional force) is assumed to be a constant value in this paper, while the detailed calculation model was not given.…”
