Saipem, a prominent engineering, drilling, and construction services giant from Italy, has recently announced an essential milestone in the Neptun Deep gas development project in the Romanian part of the Black Sea. This venture is recognized as the largest offshore natural gas project currently being developed in the European Union (EU).
In a recent announcement, Saipem confirmed that the jacket designated for the Neptun Deep gas development project has departed from its shipyard in Arbatax, Sardinia, marking a pivotal step forward after the successful completion of load-out operations. This foundation, weighing in at a substantial 7,500 tons, ranks among the largest structures ever constructed at Saipem’s Sardinian facilities.
The jacket boasts impressive dimensions, standing approximately 135 meters tall, with a base measuring roughly 50 by 50 meters. It was fabricated horizontally and will be transported in that orientation, showcasing the meticulous planning involved in its construction.
Once it reaches the Black Sea, the jacket will undergo a vertical transformation facilitated by the Saipem 7000 crane vessel. This critical phase involves lifting the jacket and installing it on the seabed, which will be secured using eight steel piles each measuring 2.5 meters in diameter. The engineering sophistication behind this operation exemplifies Saipem’s technical prowess in complex offshore installations.
The Neptun Deep gas project is a collaborative effort between OMV Petrom, the Romanian arm of Austria’s multinational OMV, and its partner, Romgaz. With a total investment estimated at €4 billion, the project aims to commence gas production by 2027. This ambitious initiative is set to enhance the energy landscape in the region, reaffirming Romania’s role in the European energy supply chain.
The development encompasses various components, including an offshore production platform, three subsea systems, and a total of ten production wells—four of which are already drilled on the Pelican South field, while six are underway on the Domino field. Additionally, an onshore gas metering and control station will be established in Tuzla, further bringing the infrastructure together.
Saipem secured its involvement with the Neptun Deep project in August 2023, undertaking significant responsibilities, including engineering, procurement, construction, and installation of the gas production platform. The jacket successfully fabricated in Arbatax will serve as the foundation for the topside module, which is set to be completed at Saipem’s shipyard in Karimun, Indonesia. This extent of collaboration across regions highlights the global interconnectivity of the energy sector.
Beyond the jacket, Saipem’s scope extends into the subsea segments for both the Domino and Pelican fields. The Domino field, located at a depth of approximately 1,000 meters, and the Pelican field at around 125 meters, emphasize the technical challenges and innovations required for successful energy extraction in such environments.
Moreover, the project entails the installation of a 30-inch gas pipeline approximately 160 kilometers long, along with an associated fiber-optic cable connecting the offshore platform to the Romanian coast. The inclusion of microtunneling for shore landing demonstrates the project’s commitment to modern engineering techniques and environmental considerations, ensuring minimal disruption to the coastal ecosystem.
Saipem highlighted the significance of the Neptun Deep initiative: “This project not only contributes to diversifying the European Union’s energy supply sources but also reinforces Saipem’s status as a leading international player in offshore energy infrastructure.” Furthermore, they expressed pride in the high level of professionalism and technical expertise present in the region, allowing it to remain competitive in advanced technology markets.
