Construction and derailing accessories for railway works
The scope of work includes all engineering, fabrication and testing works of such equipment which works as “last resort” of preventing a train from entering the wrong line.
Mechanical cleaning of cooling exchangers of compressors in the power plant of komotini
The project included the plugging of leaking heat exchangers tubes, removal of the shell, careful mechanical cleaning, reassembly and hydraulic test.
Construction and installation of furnace bases
The work included the construction and installation of six new annealing furnace bases, the construction of the hydraulic piping and accessory components, the assembling of the bases, the electrical installation of the bases and electrical panels, checks and functional tests of all equipment.
Fender replacement on off shore oil platform
On the oil platform of Hellenic Petroleum , in Thermaikos gulf, 7 fenders including treir steel structures, were replaced by new ones (manufacturer of the fenders was Fender Team AG)
Hot water generator drums
The project included the construction & certification per PED 97/23 of thirty four (34) new hot water generator drums (by means of steam injection) and their installation. The WPS and PQR procedures as well the welders’ certificates were fully approved by the owner before the project commencement.
Restoration works on the refinery breasting island and replacement of underwater pipe risers
The activities included various reinforcements of the fenders structures and replacement of thirteen (13) flanged risers 4”-14” of the underwater pipes, connecting the Breasting Island with the Shore terminal, along with hydrostatic tests at 28 bar. The project required the close cooperation of ROPI with specialized divers.
Gangway installation on the breasting island of the refinery ship loading facilities
The project included the installation of a gangway that connects the dolphin C to the platform of the Breasting Island. The damaged parts of the gangway were removed and transferred to the shore where the new sections were assembled and then were transferred and installed at the Breasting Island by a floating crane. In addition, the LPG vent line was restored and the necessary concrete blocks were cast.
Construction of a nitrogen line from the refinery to τhe polypropylene plant
Construction of a 4’ line for the supply of nitrogen to the Polypropylene plant. The design, construction and testing was carried out according to ASME Code B31.3 and the additional customer’s specifications (EXXON International Practices).
Construction of 8” pipeline from helpe refinery to the jetoil co. storage terminal in thessaloniki
The subject of this contract was the interconnection of the HELPE products loading /unloading facilities with the JETOIL’s storage terminal, with the construction of new pipelines, the relocation of equipment, new pig trap facility and the extension of the closed drain systems.
Construction of a 14” firewater line
The project scope included the construction of a new 14” underground firewater line, 1000m long within the Thessaloniki HELPE Refinery site, as an expansion of the firewater network. The main works consisted of the excavations, the construction and installation of the new line, the tie in connections with the network, the pressure testing and NDT checks, the installation of the cathodic protection system and the restoration of all site infrastructure (roads, pavements, ditches, etc.) at the end of the works.
Refinery furnace maintenance
The works included the isolation of the furnace, the decocking process, the opening of the manholes, the cleaning of the tubes in the radiant and the convection sections, the maintenance of the expansion joints, refractory brickwall repairs, the replacement of the steam generation tube manifolds removal inspection and refitting of the stack dampers.
Installation and commissioning of 4 pumps with theιr motor drivers
The subject of this contract work was the preparation of the required engineering study and the subsequent dismantling of four pumps along with their motor drivers, the replacement of the concrete bases and the construction of the new ones per Code API 686 and finally all restoration along with the piping and electrical connections.
Maintenance contract for all processing lines of a steel mill plant
Execution of the periodic maintenance works of all processing lines of the metalworks factory Hellenic Steel Mill S.A. (RIVA GROUP) in Thessaloniki, including the Pickling, Annealing, Tinning, Electrolytic cleaning line, galvanizing of the steel sheets, etc.
