A large natural gas field located in the open seas of the Black Sea has been developed with an integrated infrastructure system in order to increase the country's energy security and reduce external dependency.

This project includes comprehensive engineering components starting from the underwater production system and extending to onshore processing facilities. This system, which includes deep sea production, pipeline transportation and onshore purification processes, has been implemented with advanced technology applications and multi-disciplinary engineering solutions.

Integrated Production System with Offshore and Onshore Components

The production infrastructure, established at a depth of approximately 2,200 meters on the seabed, collects natural gas from wells spread over a wide area and transports it to the land via an approximately 165-kilometer-long undersea pipeline. This piping system has a multi-component structure that includes not only natural gas but also antifreeze, electrical, fiber optic, hydraulic and chemical circuits.

The landside section is complementary to this giant infrastructure. When the natural gas coming from the open sea reaches the treatment facility located on the shore, it is purified from its liquid, moisture and impurities and made suitable for the transmission network. However, it should not be forgotten that the success on the landside is not limited to the surface process only, but is also made possible by the infrastructure systems continuing underground.

Landside Underground Piping Systems and Engineering Consultancy

The underground piping systems on the landside of this project include a multi-faceted infrastructure that integrates with the treatment facility and includes gas, condensate, drainage, service water, fire water and other auxiliary systems. The engineering control consultancy of these systems was carried out by Noktasal Proje.

Within the scope of consultancy:

• Hydraulic modeling of underground piping networks was performed and pipe diameters, flow rates, pressure balances and system performance were analyzed.
• With 3D modeling studies, the entire system layout was created in a digital environment and optimized according to field conditions and facility layout plan.
• Overlap analysis of the systems with other infrastructure elements was performed, technical compatibility and ease of construction phase were ensured.
• Design revision suggestions were presented and implemented in order to ensure safe, long-lasting and sustainable operation of underground lines.

Engineering services provided within this scope provided critical contributions in terms of the smooth operation of the project, ease of maintenance and operational safety.

Technological Applications and System Innovations

Smart well systems, electro-hydromechanical control infrastructures and remote monitoring used throughout the project systems enable the production process to be controlled with high accuracy. By providing continuous data flow between the sea and the land, each part of the system can be monitored instantly and intervened when necessary.

3D engineering models have played an active role not only in the facility planning but also in the placement of infrastructure piping systems in this project. In this way, potential risks before construction have been minimized and design and implementation processes have been optimized.

Strategic and Economic Impact

When the project is completed, it is anticipated that 25% to 30% of the country's annual natural gas needs will be met through this source. This will reduce the burden of energy imports and significantly reduce external dependency in energy supply. At the same time, it offers a strategic development model with the economic vitality, employment increase and technological investment opportunities it provides to the region.

Conclusion

This integrated energy project stands out not only with its deep-sea production but also with its detailed engineering solutions in the landside infrastructure. In particular, thanks to the control consultancy, hydraulic analysis and 3D modeling studies of underground piping systems, the holistic efficiency of the facility has been secured. These consultancy services undertaken by Noktasal Proje have constituted an important building block in terms of the sustainability and technical success level of the project.
