Paraffin treatment of crude oil produced from the Central of Rong and Nam Rong - Doi Moi fields during transportation through uninsulated subsea pipelines
Abstract
Due to being developed in the early stages, several major oil subsea pipelines in Vietsovpetro Joint Venture are not equipped with insulation systems, causing significant difficulties in transporting high-paraffin crude oil. Specifically, the lack of insulation leads to intensive heat loss through pipeline walls, resulting in paraffin deposition on the pipe surface. Additionally, the temperature drop significantly increases oil viscosity, leading to high pressure losses during transportation.
This article analyses the difficulties in crude oil transportation through the uninsulated RP-1 → FSO-3 pipeline, the major route from Central of Rong, Nam Rong - Doi Moi fields to FSO-3 and presents the technical solutions that Vietsovpetro has researched and implemented to successfully resolve these problems.
