At JMEC Engineering, part of J. de Jonge Mechanical, we deliver integrated engineering solutions that enhance reliability, safety, and long-term performance within complex brownfield environments.

A recent project focused on the renewal and redesign of an aging pipeline system, combining two vegetable oil lines into one coordinated scope. The objective was to restore integrity and ensure long-term operational reliability.

The project involved pipeline sections of approximately 400 m and 550 m, where existing infrastructure conditions no longer guaranteed safe and reliable operation. A phased execution strategy was applied, including installation of a new pipeline alongside the existing system, followed by tie-ins and dismantling of the old lines.

High-resolution 3D laser scanning was used to capture accurate as-built conditions. This enabled precise routing on the existing pipe bridge, clash-free design, and efficient development of isometrics and material take-offs for fabrication and installation.

As part of the upgrade, pipelines were transitioned from carbon steel to stainless steel (SS-316), significantly improving durability and corrosion resistance. In addition, pipeline diameters were increased from 2.5” and 3” to 4” to support higher capacity requirements.

Following removal of the existing vegetable oil line, the new pipeline will be installed within the same corridor to optimize use of available infrastructure.

This project demonstrates the effective application of brownfield engineering principles, digital survey technologies, and phased execution strategies to deliver a reliable and future-ready pipeline system.
