Gas compressors

Description

The purpose of this public procurement procedure is to establish a Framework Agreement between the contracting entity, Dansk Gas Distribution Service Viborg A/S, (hereinafter “the Buyer”) and one (1) supplier according to which the buyer — on an ongoing basis as needed — may order the delivery of complete biomethane injection compressor installations placed in enclosure for outdoor installation (hereinafter “Compressor(s)”) to be installed, connecting the existing or new biomethane upgrading plants to the natural gas transmission network in Denmark. In addition to the delivery and installation of compressors the supplier shall on request of the buyer deliver spare parts to and continuous maintenance of the delivered compressors. The buyer establishes, maintains and operates the natural gas distribution network in Denmark. As part of the operation, the Buyer connects biomethane upgrading plants to the natural gas distribution network. It is the buyers responsibility to establish, maintain and operate biomethane injection compressors necessary for connecting biomethane upgrading plants established by the biomethane upgrading plant owners to the natural gas distribution network when so required to ensure distribution of the upgraded biomethane. Hence, the buyer needs to be able to order the delivery of compressors on an ongoing basis as new upgraded plants are connected to the gas grid. Based on experience and the present pipeline the buyer expects to connect 15 – 20 upgrading plants to the natural gas transmission network during the next years and subsequently order the delivery and installation of Compressors in connection hereto under the Framework Agreement. Based on the experience from the existing biomethane upgrading plants, the biomethane inflow is fluctuating, hence the biomethane has to be compressed from 4-7 bar to 50 bar. This is a power consuming process that challenge the compressors ability to operate with low consumption and with a minimum of noise and at the same time robust in terms of wear and tear supporting the life expectancy of no less than 20 years of operation. No oil is allowed in the compressed biomethane and no biomethane is allowed to escape from the compressors except for emergency situations. The buyer will occasionally have the need for fast deliveries, which means delivery within 5 - 6 months from placement of an order to installment and commencement of the ordered compressors. As an example of this, the buyer expects to place the first order of the delivery and installation of 10-14 compressors shortly after the signing of this Framework Agreement with the aim of delivery as soon as reasonable possible and preferably before year end 2019. The requested capacity of the compressors ordered under the Framework Agreement will vary based on the actual needs at the upgrading plant site. In addition to the delivery and installation of compressors under the Framework Agreement, the buyer expects to order certain services, e.g. preventive and corrective (repair works) maintenance of the compressors, including continuous delivery of spare parts and consumables to the compressors.
