Key Project Data

• End User: Türkiye Petrolleri Anonim Ortaklığı (TPAO)
• HIPPS System integrator: Yokogawa Malaysia
• Indra Scope: Supply of HIPPS Interlocking Manifold
• Application: Deepwater gas production 

Project Overview

The Sakarya Gas Field, located in the Black Sea, is Türkiye’s largest offshore natural gas development and a key contributor to the country’s long-term energy supply.

As part of the field development, a HIPPS-based solution was implemented to ensure safe and reliable operation under high-pressure deepwater conditions.

Indra Scope of Supply

Indra supplied the Interlocking Manifold as part of the HIPPS system provided by Yokogawa Malaysia.
The manifold is designed to support high-integrity pressure protection functions, ensuring safe isolation of Pressure Transmitters (initiators) ensuring continuous monitoring of the line pressure without risk of interruption.

For this specific project, we delivered the Interlocking Manifold (IM) with all wetted parts manufactured in Super Duplex F55. The 2oo3 voting logic is achieved using individual 1oo1 tapping manifolds, each equipped with a flushing ring and butt-weld integral needle valves. The assemblies were fully assembled and successfully tested in-house.

Each IM is installed inside our IP66 protection enclosure (Box di protezione) manufactured in painted SS316L, providing mechanical protection of the “initiators” against the aggressive offshore environment.

Key Milestone

The Factory Acceptance Test (FAT) of the Interlocking Manifold was successfully completed, confirming compliance with functional, performance, and safety requirements prior to system integration.

Value Delivered

• Reliable interlocking manifold solution for HIPPS applications
• Proven performance for deepwater, high-pressure gas service
• Seamless integration within Yokogawa’s HIPPS architecture
