Design, Manufacture, Supply and Installation of the Liquid Nitrogen (LN2) Transfer Line System for the Super-FRS Experiment Area

Brief

FAIR - Facility for Antiproton and Ion Research in Europe GmbH needs the design, manufacture, supply, installation, and testing of a vacuum-insulated liquid nitrogen transfer system for the Super-FRS experiment area in Darmstadt, Germany, over a duration of 12 months. The base scope includes approximately 200 m of transfer line connecting the tank area to HI/DESPEC and FHF1, with an option for an additional 120 m and one valve box for FHF2. The system must deliver 25 l/min of LN2 at 77 K, with specific pressure requirements. The contractor's scope includes thermal and hydraulic calculations, supports, thermal contraction compensation, AD 2000 and PED compliance, factory and site acceptance testing, and technical documentation. Award criteria are Price (30%), Delivery schedule concept (28%), Technical design (21%), and Installation and execution concept (21%). Qualification requirements include a Bidder Consortium Declaration, a Business and Professional Liability Declaration with a sum insured covering at least the order value, a Declaration of Availability for subcontractors, and descriptions of three comparable reference projects demonstrating experience in manufacturing vacuum insulated cryogenic transfer lines longer than 25m and experience on major construction sites, ideally at research facilities and accelerator installations. Additionally, a certificate demonstrating components designed and tested in accordance with AD 2000 and the Pressure Equipment Directive 2014/68/EU, a Self-Declaration Data Protection Requirements, and a Self-Declaration of Compliance with ISO 9001 (or equivalent) are required.

About the bid

The tender covers the design, manufacture, supply, installation and testing of a vacuum-insulated liquid nitrogen transfer system for the Super-FRS experiment area at FAIR/GSI in Darmstadt, Germany. The base scope comprises approximately 200 m of transfer line connecting the tank area to HI/DESPEC and FHF1, including two valve boxes with manual, pressure-relief and 24 V solenoid valves. A separately callable option comprises approximately 120 m of additional transfer line and one valve box for FHF2, with provision for this extension included in the base design. The system shall deliver 25 l/min of LN2 at a nominal temperature of 77 K, with a tank pressure of 1.3 bara and at least 1.1 bara remaining at the farthest consumer. The contractor"s scope includes thermal and hydraulic calculations, supports and thermal contraction compensation, applicable AD 2000 and PED compliance, factory and site acceptance testing, and technical documentation; the storage tanks and valve control system and wiring are excluded. Installation is provisionally targeted for completion by the end of Q3 2027, subject to confirmation.

Award Criteria

Description
Price criteria for "Preis-Quotient-Methode"
Description
The tenderer must submit a robust and traceable schedule concept. If the tenderer is not already working on the FAIR construction site, it is recommended to allow approximately two months for initial company registration on site. The tenderer must describe its experience on comparable major construction sites and explain how this experience is reflected in the schedule. Planned delivery dates for all materials and the personnel resources to be deployed, including staffing levels, qualifications and duration of deployment, must be specified in detail. If the proposed schedule deviates from the framework requirements in the tender specification or cannot meet them, a clear written justification must be provided. Overall, the concept must demonstrate realistic, traceable and risk aware planning.
Description
Pressure drop, heat input and pipe sizing. The concept should explain how these aspects interact and how the selected dimensions meet the specified operating requirements. Assumptions and calculation results should be traceable. A coherent design supported by calculations for the relevant operating conditions is assessed particularly positively. Pipe dimensions should be justified through a balanced assessment of pressure drop and heat input. Clearly stated boundary conditions, realistic allowances and consistency between calculations and the proposed design make the concept convincing. Low pressure drop and low heat input are favourable where they are demonstrated under comparable conditions and remain compatible with the specified requirements.
Description
Routing, supports, fixed points and expansion joints. The concept should show how the line can be installed and how these elements work together, taking account of installation space, accessibility and thermally induced movements. Clear routing and support drawings, well justified fixed point locations and a coherent expansion compensation arrangement are assessed particularly positively. A feasible installation sequence, accessible connections and inspection points, and clear coordination of interfaces strengthen the concept. The proposed arrangement should explain how loads and thermal movements are accommodated without conflicts between the routing, supports and expansion joints.

Qualification requirements

Description
BGB company with joint and several liability with listing of all members and their authorised representatives incl. naming of an authorised representative who shall represent the consortium in a legally binding manner vis-à-vis the Contracting authority. The tender must be accompanied by a legally binding declaration signed by all joint members that the lead firm, as authorised representative, represents the joint members listed before the Contracting authority and is jointly and severally liable, having an effect on each member, for performing the service in accordance with the contract.
Documentation Requirement
Bidder Consortium Declaration (Mit dem Angebot; Mittels Dritterklärung)
Description
The sum insured must cover at least xxxxxx the order value.
Documentation Requirement
Business and Professional Liability Declaration (Mit dem Angebot; Mittels Eigenerklärung)
Description
Only to be completed in parallel with the "Sub-contractor Declaration" and signed by the sub-contractor if partial services are to be passed on to sub-contractors (performance by sub-contractor) or if the applicant/bidder is using a sub-contractor to demonstrate suitability (hired competence - see Sub-contractor form). In the event that more than one sub-contractor is being used, several copies of this form should be filled out. One declaration of commitment should be submitted per sub-contractor.
Documentation Requirement
Declaration of Availability (Mit dem Angebot; Mittels Eigenerklärung)
Description
Description of three comparable reference projects, including the project data requested on the GSI/FAIR form. The contractor must have experience in manufacturing vacuum insulated cryogenic transfer lines for liquefied gases such as LN2, LHe, LOX or comparable media, and must demonstrate that transfer lines longer than 25 m have been manufactured and installed. Experience on major construction sites is required, ideally at research facilities and accelerator installations.
