Tupras, a leading producer in Turkey’s refining sector and the country’s largest industrial enterprise, supports its operations with reliable, high-performing safety software, as well as making risk performance accessible company-wide with one interface for all refineries.

Tupras manages its safety instrumented functions (SIFs) using SIFpro by Cenosco, a Dutch company that delivers solutions for asset integrity.

As a multi-faceted and comprehensive program, SIFpro enables Tupras to review and analyse more than just SIFs including instrument failure rates, maintenance task interval optimisation, perform layer of protection analyses (LOPAs) and safety integrity level (SIL).

Tupras operates four oil refineries, with a total annual crude-oil processing capacity of approximately 30 million tonnes.

According to Dogus Uzun, Process Control Superintendent at Tupras İzmir Refinery: "Each of our refineries has between 2,000 and 3,000 SIFs in place to protect our people and equipment. Cenosco’s program is robust and easy to use; it eliminates daily problems and gives us peace of mind."

THE APPROACH AND RESULTS

Throughout the collaboration between Tupras and Cenosco, the teams worked together to create valuable feedback–upgrade cycle.

This ensures that the software always meets Tupras’s needs as well as complying with all international standards, including IEC61508/61511.

The SIFpro software shows users all the key information they need on a single dashboard and provides clear links between process safety and reliability issues.

Moreover, the latest versions of SIFpro are hosted on a central server, avoiding any delays in downloading or uploading information.

@SIFpro is constantly being improved, so, even if our processes change, we know we can rely on the software. SIFpro has long been essential to our daily operations at Tupras. That’s a big advantage in our eyes," says Uzun.

Following the successes, the teams at Tupras and Cenosco are planning to grow their partnership, with more upgrades in the pipeline.

Expressing satisfaction, Uzun say: "Cenosco listens to our feedback and understands our concerns. Safety processes are paramount, but better safety is closely linked to maintenance cost optimization, reduced downtime, and other efficiencies. Over the years, we’ve provided a lot of feedback on the different features of the program and on the overall dashboard, and with every upgrade we can see how it has all been taken into account."

The overall goal is to increase the visibility of the intricate relationships between safety processes and equipment maintenance and reliability.
