Tackling harsh conditions with innovation: INTECH helped save millions of dollars on a project

INTECH Process Automation designed RTUs for an End User in Pakistan that can operate in extremely hot weather conditions while keeping their controllers within reference temperatures without resorting to any power-hungry cooling methods – effectively saving a large amount of expenditure on the project.

An End User in Pakistan operates one of its gas production facilities in the harsh desert environments of interior Sindh. At the time of this project, the facility had Remote-I/Os (RIOs) on existing wellheads but all their controllers were kept in cooled LER buildings away from the fields, since they couldn’t endure the harsh conditions out there (≥70° C). A 40+ Km fiber optic (FO) network linked all 20+ wellheads and LERs to facilitate data flow from RIOs to controllers in addition to all regular communication back to the plant. In this setup, the FO network was operating near full capacity.

When the end user carried out an expansion plan, they asked INTECH for the commissioning of 8 new wellheads. The scope was to incorporate these new wells into the existing 20+ wells following the same method as before i.e. RIOs in the field and controllers in cooled LER buildings, but here the project faced a major roadblock. The existing FO network could not possibly handle all the extra communication.

The obvious solution was to install a new 30+ Km FO network replicating the existing system that could then handle RIOs and other data from new wells back to the plant without overloading the existing system. The controllers were rated for operation under 70° C and could not be conventionally placed in the field, but installing another FO network would increase project expenditure by millions.

INTECH devised an efficient alternative and designed RTUs specifically for the harsh conditions that could house both the controllers and RIOs in the field. INTECH’s engineers used fans and an innovative panel design that would help regulate controller temperature within reference values without resorting to air conditioning, thus enabling low cost operation. This panel design removed the requirement for a new FO network since the controllers now only needed a fraction of the original bandwidth for SCADA communication, which the existing network could easily support.

This new design helped the end user save the otherwise necessary cost of installing a 30+ Km FO network, while INTECH achieved a significant milestone in RTU design.
