NIS Pančevo Oil Refinery
Delayed Coking Unit (Final Phase of Project)

In 2016, being one of the leading and most important business entities in Serbia, Naftna Industija Srbije (the Petroleum Industry of Serbia/NIS) launched the second phase of the modernization of the Pančevo Oil Refinery processing complex. The construction of a new deep processing plant, a delayed coking unit with the necessary facilities and infrastructure, represents one of the significant projects contributing to the modernization of the existing processing complex. The main contractor is the European branch of the American company CB&I (Brno, Czech Republic) with whom Energoprojekt Industrija in November 2016 entered into a contract on design services, project certification and the obtaining of permits from competent bodies.

Deep petroleum processing (delayed coking) refers to the process of enhancement and conversion of heavy residue created by processing petroleum into lighter, liquid and gaseous fractions. The residue has the form of concentrated, solid (solidified) carbon – petroleum coke, which is used as a fuel (coke replacement or industrial raw material). The delayed coking unit is the main unit for deep petroleum processing with a processing capacity of 2,000 t of raw material per day. The raw material is processed in Pančevo Oil Refinery, yielding between 474 and 606 t of petroleum coke daily. The second most important unit is the Coke Handling System. In addition to these new main units, two new/refurbished appurtenant units, i.e. DCU auxiliary facilities shall be executed, such as the necessary extension of the cooling system, new transformer substation, reservoir tanks, pumping stations, sour water stripping plant, amine III regeneration plant and interplant transfer facilities – the infrastructure and circulations for the supply of the necessary raw materials and utilities, including corridors for transporting products to storage units and loading points within the complex (by truck and by train).

The verification of all designs carried out by CB&I as the process contractor, the execution of all structural analyses for concrete and steel structures of the plant, the development of all designs for auxiliary facilities within the plant, the inspection and certification of pressure pipeline designs and mediation in the permit application process with the competent bodies are entrusted to Energoprojekt Industrija. The contract shall cover the following technical documentation: Building Permit Design, Detailed Design and As-Built Design.

The contract was closed in December 2016, after which documentation certification and the preparation of the Building Permit Design began. The location conditions were obtained in February 2017, and the Building Permit Design with the design review was finalized in May 2017. Consequently, the building permit for the whole complex was obtained on 10 July 2017.

The Detailed Designs were developed and submitted to the Investor successively. They were used as the basis for plant construction and refurbishment and equipment installation. The complete Detailed Design documentation necessary for obtaining the Ministry of the Interior’s consent was first given to the Investor in November 2018. The documentation was then submitted to the Ministry for unofficial review on two other occasions and was subsequently amended and edited. So far, a comprehensive Detailed Design has been completed too, comprising 119 books: 24 concrete structure books, 28 steel structure books and 21 mechanical systems books, while the rest tackle architecture (3), transport structure (3), plumbing (5), electric power supply (12), controls and instrumentation (9), process (6), preparatory works (2), telecommunication systems, signalling systems (gas and fire detection); there are also the Main Fire Protection Report, Hazardous Area Analysis and Soil and Facility Observation Report. The design documentation has been submitted to the Central Evidence of Unified Procedures for the Issuance of Construction Permits and the documentation as a whole is expected to be approved by the Ministry of the Interior.

The execution works are in their final stage. Energoprojekt Industrija’s design engineers have been continuously monitoring the demands of the site and edited the documentation accordingly, thus simultaneously influencing the development of the As-Built Design. Since the planned deadline for the completion of works on the whole delay coking unit is the first trimester of 2020, the design engineers in all departments have intensified the pace of work on the remaining technical documents which are yet to be prepared, striving to adhere to the Detailed Design time schedule completely and fulfil this contractual obligation.

The fact that the total number of files in the As-Built Design record is 14,765, of which 7,500 are isometric drawings of various flow pipelines, testifies to this project being one of the most challenging ongoing tasks on the level of the entire Energoprojekt system. This complex project requiring outstanding technical and technological knowledge and the understanding of the specific features of the process has provided an opportunity for Energoprojekt Industrija to perfect professional competences and gain new references relevant to projects of this and similar nature, conducted not only in Serbia and ex-Yugoslav countries, but in other countries too.

Refurbishment and Construction of Nikola Tesla Airport Terminal Building and Construction of Appurtenant Buildings and Infrastructure

By means of several contracts, Energoprojekt Industrija continue their co-operation with Vinci Constructions on the development of technical documentation for the refurbishment and construction of the Terminal Building and the construction of the necessary technical facilities at the air carrier airport in Belgrade. Works on a total area of approximately 92,000 m2 are planned to be completed by 2025, executed in two phases:

• By 2020 (Phase I)

• By 2025 (Phase II).

So far, the technical documentation for the Preliminary Design has been completed and positively evaluated by the Ministry’s Review Committee (on 24 July 2019), and the Building Permit Design for Terminal Building (Phase I) has received a positive design review. The building permit is expected to be issued soon. The Preliminary Designs for the appurtenant facilities (Solid Waste Treatment Plant – Landside, New Heating Plant, etc.) have been completed and the Building Permit Designs are being prepared.

The civil designs pose a certain problem, since the design documentation based on which the building permit was obtained and the As-Built Designs of the existing Terminal Building do not match (there are not enough piles and the conditions for the new foundation solution turned out to be inconvenient – these are circumstances which required the civil engineers to work even harder). The Terminal Building Phase I Detailed Design documentation is being prepared, and at the same time, design engineers have been engaged on Terminal Building Phase II Preliminary Design, which will be divided in two subphases (Subphase I – Pier C Extension and Subphase II – Terminal T3). Energoprojekt Industrija continue to diversify their professional engagement outside the industrial facilities sphere, working on public buildings designed for simultaneous exploitation by a great number of users, while paying attention to the fusion of function and form in interior design, striving to maintain a holistic view of space and enable visual communication.

The training and experience gained on this project will enable young engineers to work outside of their professional niche and be more flexible and adaptable to different challenges of design in all engineering fields. They will certainly work under pressure and be required to meet short deadlines, while being responsible for maintaining a high level of quality in their work. In compliance with EP Industrija’s business culture, this experience will positively influence the long-term plans, activities and competitiveness of the company’s business capacities.
