In 2015, Teekay Petrojarl Production was executing modifications of Petrojarl 1 for deployment at the Atlanta field offshore Brazil. A study was performed to analyse depressurisation and fire integrity of the process systems. The analysis was performed by Petrell with the use of VessFire and was finished in the spring of 2016.
The liquid filled dehydrator system contains low API crude oil operating at high temperature (130°C) and high viscosity. The initial study was revisited to fine tune the results considering these challenging depressurization conditions and to verify fire integrity. This project was completed during spring of 2020.
