    Brief

    Einkauf is planning the procurement of a 200 m^3 liquid argon cryostat, which is a pressure vessel with an outer diameter of 7 m and a height of 10 m, to be constructed underground at the Italian Gran Sasso laboratory. The buyer is searching for a company with experience in constructing similar-sized pressure vessels and with remote-site mounting and welding experience. Interested companies must visit LNGS before preparing an offer to understand the boundary conditions.

    About the bid

      Subject of the expression of interest: The LEGEND-1000 experiment (www.legend-exp.org) will operate 1000 kg of germanium detectors in a 200 m^3 liquid argon cryostat at the Italian Gran Sasso laboratory (www.lngs.infn.it). LNGS maintains 3 large halls (18 m x 18 m x 100 m) under the Gran Sasso mountain. Access is via the A24 highway tunnel connecting Termo to L'Aquila with an exit in the tunnel. The Max Planck Institute for Nuclear Physics (MPIK) is responsible for the cryostat. The cryostat has an outer diameter of 7 m and a height of 10 m. It is a pressure vessel that has to be constructed underground according to PED 2014/68/EU following the requirements of EN 13445. The entrance door to the halls (4 m wide and 4.5 m high) limits the size of the parts that can be shipped. MPIK is searching for a company with experience in the construction of pressure vessel of similar size and with experience of remote-site mounting and welding. The tender documentation give more details about the project, LNGS and the cryostat. Interested companies have to visit LNGS before preparing an offer to understand the boundary conditions. The project is subject to funding approval. Information via: https://mcloud.mpi-hd.mpg.de/index.php/s/dydCd4rZ6FkwEgE

      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.
