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

Indra annuncia la propria partecipazione a LNG2026, in programma dal 2 al 5 febbraio 2026 presso il Qatar National Convention Centre di Doha, Qatar.

LNG2026 rappresenta il principale evento internazionale dedicato all’LNG, riunendo leader industriali, decisori istituzionali, autorità regolatorie e stakeholder per approfondire temi di innovazione, sostenibilità e cooperazione lungo l’intera catena del valore dell’LNG.
Il tema dell’edizione 2026, “Leading LNG: Powering Today and Tomorrow”, sarà incentrato sull’evoluzione dei mercati, sulle innovazioni tecnologiche e sul ruolo strategico dell’LNG nella sicurezza energetica globale.

Presso lo Stand 8250, Indra presenterà la propria gamma completa di soluzioni di valvole progettate specificamente per applicazioni LNG ed energy, tra cui:

• Valvole Double Block & Bleed (DBB) per la massima sicurezza e l’isolamento dei processi
• Configurazioni Split Body e Integral Body per una maggiore facilità di manutenzione
• Manifold di strumentazione per un controllo accurato dei processi strumentali
• HIPPS Interlocking Manifolds, soluzioni di sicurezza certificate SIL 4 per sistemi High Integrity Pressure Protection System, caratterizzate da costruzione integrale con più linee DBB comandate da un unico elemento di attuazione
• Soluzioni personalizzate sviluppate in funzione delle specifiche esigenze di progetto

Grazie a decenni di esperienza applicativa nei settori oil & gas, chimico, petrolchimico, energy, offshore e LNG, Indra combina una produzione interamente italiana con un approccio consulenziale e su misura.

La profonda conoscenza delle criticità tipiche degli impianti LNG — dalle condizioni criogeniche ai più rigorosi requisiti di sicurezza — consente a Indra di offrire soluzioni di valvole affidabili, ad alte prestazioni e accessori complementari.

Vi aspettiamo allo Stand 8250 per scoprire come le soluzioni Indra possano contribuire a migliorare sicurezza, efficienza e affidabilità dei vostri progetti LNG.

Project Overview

ADNOC Gas Processing operates one of the most extensive sales gas pipeline networks in the Middle East, approximately 3.000 km of infrastructure stretching across Abu Dhabi, supplying gas to consumers at precisely controlled pressures and flow rates.

As part of a major upgrade program at the Habshan Gas Compressor Plant (HGCP), the project required a state-of-the-art High Integrity Pressure Protection System (HIPPS) to safeguard critical process equipment and personnel.

The result is what has been recognized as the largest HIPPS ever built, integrated by Orion HIPPS and recently presented in Dubai.

Indra is proud to have contributed a core component of this landmark installation.

The Challenge

A HIPPS operates as a Safety Instrumented System, designed to prevent overpressure events from reaching downstream equipment by triggering automatic isolation before dangerous conditions develop.

In this application, the demands were exceptionally stringent: high-pressure sour service duty, a wide operating temperature range, and a harsh field environment characterized by humidity, salinity, and sandstorms, all while meeting SIL 4 integrity requirements in accordance with IEC 61508 and IEC 61511.

The instrument isolation architecture required a 2oo3 voting logic (two-out-of-three) on pressure transmitters, demanding a manifold solution capable of supporting three transmitters in continuous operation while maintaining full process isolation capability and material compliance for sour service conditions.

Indra's Solution

Indra supplied a purpose-engineered Double Block & Bleed interlocking manifold configured specifically for 2oo3 applications.

Rather than a conventional multi-component assembly with multiple potential leak points, Indra's integrated design consolidates isolation, venting, and position feedback into a single compact unit.

Key features include:

• Double Block & Bleed needle valve configuration ensuring complete process isolation and safe venting during maintenance
• Intrinsically safe proximity switches (ATEX/IECEx/ECAS certified) integrated directly into the manifold body, providing position feedback to the safety logic solver
• High-pressure flanged process connection with all wetted components in SS 316/316L, fully compliant with NACE MR 01-75 / ISO 15156 for sour service duty
• Weatherproof stainless steel enclosure (IP66) with thermal insulation, safety viewer window, and dedicated Ex ia junction boxes — engineered to protect instrumentation against the demanding Abu Dhabi field environment
• SIL 4 certified assembly in accordance with IEC 61508 and IEC 61511

The complete assembly underwent full factory acceptance testing at Indra's facility in Magenta, Italy, including functional verification of the interlocking mechanism, hydrostatic pressure testing, and positive material identification on all wetted components.

Outcome

Indra's Interlocking Manifold delivered a compact, fully integrated solution that simplified field installation, reduced potential leak paths compared to conventional assemblies, and provided the certified safety performance required for one of the most demanding oil and gas environments in the world.

Manufactured entirely in Italy, the assembly reflects Indra's commitment to engineering precision and project reliability at the highest level.

Being present in Dubai at the unveiling of this record-breaking installation is a point of great pride for the entire Indra team, and a testament to what is achievable when the right partners collaborate around shared standards of excellence.

We are proud to announce the successful completion of a new Factory Acceptance Test (FAT) together with our customer Thyssenkrupp. The FAT involved two systems featuring 2oo3 voting logic, each built with a single 1oo1 Interlocking Manifold, complete with flanged flushing systems and self-regulating heating.

Following the positive FAT outcome, our IM Series Interlocking Manifolds are now ready for shipment to the Qatar Fertilizer Company (QAFCO) site, as part of the Ammonia Plant 7 (QAFCO 7) project.

This achievement marks another significant milestone for INDRA, made possible by the commitment and expertise of our entire team.

A special thank you goes to the Thyssenkrupp staff for their outstanding collaboration, which played a key role in meeting all contractual delivery deadlines.

We are now ready to take on new challenges together with Thyssenkrupp!
