New clarification added: Good afternoon. Please clarify regarding LOT 2. According to the technical requirements for the gas metering unit provided by you, the diagram and the number of equipment in the cabinet are not clear. If we are considering a gas metering unit with an express control line, why:1. in clause 1.5.1.4 - 1 straight section is indicated;2. in clause 1.5.1.6 - 1 insert is indicated;3. in clause 1.5.1.11 - 1 tap is indicated;4. in clause 1.5.1.9. - 1 pressure gauge is indicated.With such a quantity of equipment, it is impossible to make a high-quality gas metering unit that will meet all the specified standards from the Customer.Please make changes to the technical requirements, or attach a document that provides for such technical specifications.Also, please specify separately: is a bypass line needed in the express control line?Dear BidderThank you for your request. Please find the answers below.Lot 2. Clause 1.5.1.4 will be amended to be read as follows: “Set of straight pipeline sections for the turbine gas meter, consisting of: 1) Inlet section with a length according to the manufacturer’s recommendations, but not less than 3 DN, with DN200 PN 1.6 MPa flanges — 2 pcs.; 2) Outlet section with a length according to the manufacturer’s recommendations, but not less than 2 DN, with DN200 PN 1.6 MPa flanges — 2 pcs.”.

The proposed design shall comply with the turbine gas meter manufacturer’s recommendations, the requirements for natural gas metering units, and the applicable regulatory documents of Ukraine.No bypass line is needed in the express control line.Thank you.

New clarification added: 1. Section Q2 states that the bidder must have been continuously engaged in the supply of the proposed or equivalent equipment for at least the last 3 years.Please clarify what the procurement organizer means by continuous supply. For example, if a manufacturer has been supplying both GHS and boiler rooms for the last three years, will this be considered continuous supply, or should only GHS be included in the manufacturer’s range for the last 3 years?Please also clarify what is meant by equivalent equipment.2. Section Q8.2 states that the bidder must provide certificates of compliance with Ukrainian technical requirements (for each product) with the tender proposal.In accordance with Part Two of Article 23 of the Law of Ukraine “On Standardization”, national standards are applied on a voluntary basis, except in cases where their application is mandatory established by regulatory legal acts.In addition, according to the Law of Ukraine “On Technical Regulations and Conformity Assessment”, legal regulation in the field of product conformity confirmation is carried out through technical regulations and the conformity assessment procedures provided for by them, and voluntary conformity assessment is also allowed. That is, the obligation to obtain a certificate is possible only if this is directly provided for by the legislation for the relevant type of product.Additionally, we note that in Ukraine the former List of products subject to mandatory certification has lost its validity based on the order of the Ministry of Economic Development of Ukraine dated 01/26/2018 No. 93; the relevant order approving such a List contains a direct note on the loss of validity. Therefore, the requirement for mandatory certification cannot be considered general for all products without a direct norm of special legislation or technical regulations.In view of the above, we ask you to review the procurement conditions and remove this condition (as discriminatory?).Dear BidderThank you for your request. Please find the answers below.The requirements “Bidder must be in continuous business of supplying of the offered or equivalent equipment for at least past 3 years” means that the Bidder is in business (registered) for at least 3 full years and has experience (proven previous experience) in supplying offered (identical to the ones required under this RFQ) or equivalent (gas cabinets of various configuration and capacity) goods during past 3 years.This requirement means that the Bidder must provide evidence that the goods are compliant with Ukrainian technical standards and are allowed to be used in Ukraine. The requirement is mandatory and can not be changed.Thank you.

The same pressure gauge must be installed at the outlet of the pressure-reducing unit. Therefore, a larger number of pressure gauges is required within the pressure-reducing unit, specifically:1.5.2.1.2—required: 1.0-0-60 kPa—1 pc., 2 pcs. required1.5.2.1.4—required: DM 05-100 (M)-1.0-0-60 kPa—16 units, 32 units requiredIt is possible to make changes3. LOT 1  1.5.2.3  Flanged shut-off valves:According to the tender documentation, the combined cabinets specify the connection pipe diameters (inlet DN and outlet DN), as well as the maximum gas velocities in the piping. To avoid conflicting requirements in different parts of the specifications, the following items must be amended:1.5.2.3.1—requires DN100 1.6 MPa—4 units; should be DN100 1.6 MPa—3 units and DN150 1.6 MPa—1 unit1.5.2.3.6—requires DN100 1.6 MPa—4 pcs; required: DN100 1.6 MPa—3 pcs and DN125 1.6 MPa—1 pc1.5.2.3.7—Required: DN50 1.6 MPa—4 pcs; needed: DN50 1.6 MPa—3 pcs and DN65 1.6 MPa—1 pc1.5.2.3.10—DN80 1.6 MPa is required—4 pcs; DN80 1.6 MPa is needed—3 pcs and DN100 1.6 MPa—1 pc4. LOT 1  1.5.2.4  Pressure regulator.For item 1.1. G400, 100/100 - NORVAL/G DN50 T.375 + SN-91 (or an equivalent brand/model with the same or better technical characteristics and a maximum flow rate of 20% = 1,257.78 m³/h) - 1 pcTo meet the requirements of section 1.4: “The gas velocity in gas pipelines must not exceed 15 m/s for pipelines upstream of the regulator; downstream of the regulator, it must not exceed the values recommended by the regulator manufacturer.” In the G400 100/100 cabinet, according to calculations, the gas pipeline diameter at the pulse sampling point should be DN150 mm, and the diameter of the cabinet connection gas pipeline, in accordance with section 1.2.1, should be DN100 mm.Therefore, we propose installing a DN150-100 reducer on the outlet pipeline after the cabinet; however, this requires an adjustment to section 1.5.2.3.1 (as noted above)Dear BidderThank you for your request. Please find the answers below.Lot 1. Clause 1.5.1.11. The technical requirements stipulate that there should be no shut-off devices between the filter and the gas meter, and the purge pipeline is installed after the meter's outlet shut-off device.

New clarification added: LOT1. Please pay attention to clause 1.4 where the restrictions on gas velocity in gas pipelines are indicated. We draw your attention to the fact that this requirement cannot be met with the specified parameters of the gas pipeline outlet diameters in the products under clauses 1.1 and 1.5. To meet the requirements of clause 1.4, it is necessary to increase the diameter of the pipeline after the regulator in both cases. , namely: in clause 1.1 it must increase to Dn 125mm, and in clause 1.5 to Dn 100mm. Accordingly, we ask you to change all related parameters: flange valves, outlet diameter, and also decide whether it is necessary to change the diameter of the bypass line.Dear BidderThank you for your request.The requirements for item 1.1 will be amended to be read as follows: “Gas cabinet with gas metering and reduction units (G400) 100/150  - 1 PCS”.The requirements for item 1.5 will be amended to be read as follows: “Gas cabinet with gas metering and reduction units (G160) 80/100  - 1 PCS”.Thank you.

New clarification added: LOT1. Dear customer, please note that Ukrainian legislation is undergoing changes in connection with adaptation to EU standards. Our appeal is currently related to the use of pressure gauges with accuracy class 1.5 in the territory of Ukraine. Until the end of last year, pressure gauges were used only with this accuracy class. Today, new, adapted standards come into force, in which accuracy class 1.5 is changed to accuracy class 1.6. Now is the transition period and pressure gauges, depending on the manufacturers' stock, can be supplied with both accuracy classes, so please anticipate this moment and make changes to the technical requirements. Now is the transition period and pressure gauge manufacturers, depending on the stock, can supply pressure gauges with both accuracy classes. We also draw your attention to points Q8.6.10 and Q8.6.11. In both points, the parameters of the pressure gauges as part of the reduction unit are determined, in this regard, we ask you to change the accuracy class of the pressure gauge in Q8.6.11. from 1.0 to 1.5(1.6). Our appeal generally concerns the following points: Q8.6.10, Q8.6.11, 1.5.2.1.1, 1.5.2.1.2.Dear BidderThank you for your request. Please find the answer below.Please note that the requirements in the mentioned clauses are minimum requirements and are in line with the current standards. Bidders are free to offer the equipment with higher accuracy class which will be considered acceptable and compliant with the requirements.Thank you.

New clarification added: LOT 1. Dear customer, please provide information on the output pressure ranges for each cabinet. According to the parameters of the pressure gauges that are installed after the regulator, namely DM 05-100 (M)-1.0-0-60 kPa - 1 pc, gas cabinets should have an output medium pressure, but the markings of some regulators have the BP mark (FES BP. FEXS L 100 BP, FEX L 75 BP, DIVAL 500G BP), which indicates either the need to replace the pressure gauge range, or an error in the labeling of the regulators. Please provide an answer and, if necessary, make changes.Dear BidderThank you for your request. Please find the answer below.We clarify that, for Lot 1 gas cabinets, the maximum operating pressure downstream of the regulator shall be 10 kPa.In this regard, the use of pressure gauges downstream of the regulator with a lower pressure measuring range than the one specified in the technical requirements is allowed, provided that such range ensures proper control of the outlet pressure and complies with the requirements for safe operation of the equipment.The BP designation in the specified pressure regulator models is not an error and corresponds to the required operating parameters of the regulators for this application.The Bidder shall propose a pressure regulator in the appropriate configuration ensuring a maximum operating pressure downstream of the regulator of 10 kPa, and shall confirm compliance of the proposed equipment by submitting the manufacturer’s technical documentation, passport, catalogue, or another supporting document.Thank you.

New clarification added: LOT 1. Dear customer, please pay attention to positions 1.5.1.11.2-1.5.1.11.4, 1.5.1.11.7. These are welded taps in the metering unit, 1 of which should be used per meter in each cabinet. Please provide information on the location of the second tap and check whether this is a mechanical error.Dear BidderThank you for your request. Please find the answer below.We confirm that the number of welded shut-off valves specified in clauses 1.5.1.11.2–1.5.1.11.4 and 1.5.1.11.7 is correct and is not a mechanical error.For the relevant items, the requirement provides for two welded shut-off valves per each cabinet. One shut-off valve is located upstream of the gas meter / metering unit, and the second one is located downstream of the gas meter, at the outlet of the metering unit, before the reduction unit.Thank you.

New amendment added #1: Dear BiddersPlease be advised that the below amendments are made for the RFQ requirements (Section II Schedule of Requirements):Lot 1. Item 1.4 is now amended to be read as follows: “Gas cabinet with gas metering and reduction units (G25) 50/40 - 1 PCS”.Lot 1. Clause 1.3 is now amended to be read as follows: “The design working pressure of the gas pipeline connected to the combined cabinet is: for item 1.1 -  Pmax=1.2 MPa, for items 1.2 - 1.10 - Pmax=0.3 MPa”.Please check the amended documents RFQ_Section_II_Schedule of requirements_Gas cabinets_RFQ_2026_62854_rev1 and RFQ_Section_III_Returnable Bidding Forms_Gas cabunets_RFQ_2026_62854_rev1 in the Documents section.Thank you.

New clarification added: The technical specifications do not contain information regarding an additional output for connecting a cogeneration unit. Please confirm that these gas cabinets should not have these additional outputs or make.Dear BidderThank you for your request. Please find the answer below.We confirm that the technical requirements do not provide for separate additional outlets for connection of a cogeneration unit. The gas cabinets shall be manufactured in accordance with the parameters specified in the technical specifications, in particular with the required inlet and outlet nozzles of the corresponding diameter for each item.Thank you.

New clarification added: The technical requirements do not include a safety relief valve in the reduction unit. This is a mandatory device. Please clarify the requirements and whether a relief valve is required in the reduction unit?Dear BidderThank you for your request. Please find the answer below.The technical requirements of the tender documentation provide that the reduction unit shall be equipped with a pressure regulator of the relevant model specified in clauses 1.5.2.4.1–1.5.2.4.10, or with an equivalent brand/model having the same or better technical characteristics.The pressure regulator models/regulator configurations specified in the tender documentation include the relevant safety/protection devices, in particular overpressure protection devices, such as slam-shut valves or other integrated protective elements, depending on the design of the specific manufacturer’s model.Therefore, it is not necessary to specify a safety valve as a separate item within the reduction unit, since the requirement for the relevant protection is ensured through the requirement to supply the specified pressure regulator model or its equivalent.If an equivalent brand/model is proposed, the Bidder shall confirm that the proposed pressure regulator has the same or better technical characteristics, including the necessary safety/protection devices required for the safe operation of the reduction unit. Such confirmation shall be provided as part of the technical proposal by submitting the manufacturer’s technical documentation, passport, catalogue, or another document confirming the compliance of the proposed equipment with the requirements of the tender documentation.Accordingly, the requirements of the tender documentation remain unchanged. The Bidder shall propose the pressure regulator specified in the relevant clause of the technical requirements, or an equivalent brand/model with the same or better technical characteristics, including the necessary safety/protection functions.Thank you.

New clarification added: According to the “Code of Gas Distribution Systems” approved by the Cabinet of Ministers of Ukraine No. 2494 dated 30.09.2015, Section II, paragraph 1 states that “A gas distribution system is a technological complex consisting of organizationally and technologically interconnected facilities intended for the distribution of natural gas from gas distribution stations directly to consumers, the pressure of which may not exceed 1.2 MPa”. According to the technical specifications: The maximum value of the working pressure (overpressure) is not less than 0.3 MPa.In connection with the above, please correct the values in clauses 1.5.1.3.1-1.5.1.3.7 PN for 1.2 MPa filters or indicate that the value of 1.6 MPa applies to flanged connections.Dear BidderThank you for your request. Please find the answer below.We confirm that the maximum design operating pressure of the gas pipeline connected to the gas cabinet is Pmax = 0.3 MPa for Items 1.2–1.10 and Pmax = 1.2 MPa for Item 1.1, in accordance with the technical requirements. The value PN 1.6 MPa is specified specifically for the flanged connections and does not represent the operating pressure of the gas distribution system or of the gas filters themselves.Thank you.

New clarification added: 1.2.1 For item 1.1. G400, 100/100 – 100 mm (high pressure gas pipeline), but item 1.3 states that the Design working pressure of the gas pipeline connected to the combined cabinet is Pmax=0.3 MPa, which contradicts each other. Please make changesDear BidderThank you for your request. Please find the answer below.Clause 1.3 will be amended to be read as follows: “The design working pressure of the gas pipeline connected to the combined cabinet is: for item 1.1 -  Pmax=1.2 MPa, for items 1.2 - 1.10 - Pmax=0.3 MPa”.Thank you.
