Section II: Object
Tender for Design, Delivery, erection and Commissioning of a Retrofit Steam Turbine
I/S REFA (hereinafter ‘REFA’) operates a waste-to-energy combined heat and power plant in Nykøbing Falster, Denmark. Due to the condition of the existing turbine, showing heavy erosion-corrosion damage in its low-pressure parts, as well as reaching the end of its service life, REFA has decided to remove the existing and procure a new steam turbine. The tender concerns a turnkey project including design, manufacturing, delivery, erection, commissioning, testing and 1 overhaul of a retrofit turbine.
Nykøbing Falster, DENMARK.
Design, manufacturing, delivery, erection, commissioning, testing and 1 overhaul of a complete retrofit extraction condensing steam turbine including all necessary instrumentation and control to be installed on the existing spring supported main steel frame and integrated into the existing plant. The retrofit turbine is expected to be ready for hand-over in July/August 2021.
The delivery includes all piping modification works, inclusive calculation, materials, welding, NDE and pipe support for integration into the existing plant. The turbine will be operated from the central control room and the delivery includes the control and protection system integration into the existing DCS and vibration monitoring system.
The delivery includes dismantling of the existing turbine. Civil work for dismantling of the existing turbine or erection of the retrofit turbine is not included.
The turbine will receive steam from a waste incineration boiler at approx. 48 bara and 410 C. The casing must have 2 extractions, the first supplying the deaerator and the second supplying the high-pressure district heat condenser, heating district heating water between 78 C to 89 C. The high-pressure district heat condenser also serves as condenser during plant start-up or during turbine by-pass operation. The steam is exhausted into the low-pressure district heat condenser, receiving district heating water with temperatures varying between 40 C to 60 C. The turbine load range is between approx. 1 MW to full load. At low load operation the boiler can be operated at maximum load, where surplus steam is sent to the high-pressure district heat condenser via the existing turbine bypass. The turbine allows a load change from minimum load to full load within 15 minutes.
The retrofit turbine allows to reuse as much of the existing equipment as possible, in particular, gearbox, generator, district heat condensers and deaerator. Re-use of the existing turbine auxiliary equipment, were useful, is possible, but subject to the same requirements, obligations and guarantees as for a new installation.
The defects liability period for the equipment within the scope of supply is 2 years. During the liability period any fault or defect of the delivered equipment is mended by the applicant.
The turbine is to be designed in accordance with today’s highest technical standards and quality applied to equivalent systems, for a service life of more than 20 years, operating on a very high load for more than 8 000 hours yearly, with an availability of more than 97,5 %. The turbine design should be simple and robust, using adequate material qualities to cope with erosion and corrosion within its wet sections.
The tender includes an option for a 5 year maintenance agreement and an option for the extension of the maintenance agreement for a period of subsequent 5 years.
The limitation of applicants will be based on an evaluation of which applicant has documented the most relevant previous references in comparison to the purchase described in II.2.4). The evaluation of relevant previous deliveries is based on projects concerning the delivery of extraction condensing steam turbines of a size between 5 to 15 MW and retrofit projects including similar deliveries as described in Section II.2.4) will be weighted more positively than other projects. REFA will focus on the 2 best references of each applicant in regard to this selection but look at the quality and amount of the remaining references in case the 2 best references of more applicants are equally good based on the above.
Please note that any ambiguities and/or incomprehensibilities in the information submitted under Section III.1.3) may be regarded negatively in the evaluation when selecting the limited number of applicants.
The tender includes an option for a 5-year maintenance agreement from the date of hand-over and an option to extend the maintenance agreement with another 5 years.
REFA has decided not to divide the contract into lots as this is expected to unduly increase the cost as well as the risk regarding the integration of the different deliveries under the contract.
Section III: Legal, economic, financial and technical information

— steam turbine type, power output, product designation and product production facility,
— steam pressure, temperature and flow at the inlet, extractions and exhaust,
— information on the contracting client and contact person,
— information on when the project was carried out, incl. start and end date, manufacturing, erection and commissioning time periods,
