Expired Tender for Calibration Standard Equipment for Hydrogen Refueling Station Gas Flow Meters by Norwegian Metrology Service

Project Title: Calibration Standard Equipment for Hydrogen Refueling Station Gas Flow Meters

Project Overview: This project aims to procure a mobile calibration unit named "Heavy Duty Field Test Standard (HDFTS)" for the on-site calibration of gas flow meters at hydrogen refueling stations. The unit must be capable of being loaded onto a car trailer and transported to refueling stations for use.

Core Deliverables: A complete HDFTS system, primarily consisting of:

Coriolis Measurement Unit (CMU): Includes two parallel Coriolis mass flow meters and their cooling system (capable of cooling the flow meter body to -35°C to -10°C), equipped with necessary interfaces, sensors, and designed for portability (weight < 60kg).

Hydrogen Storage Tank System (HST): A tank system with a total capacity of at least 600L (recommended not to exceed 1000L), including at least one tank with a capacity of 100–150L. Total weight must not exceed 1100kg and must fit into a car trailer of specified dimensions.

Automation and Data Acquisition (DAQ) System: Includes control software, a computer (preferably pre-installed with Windows 10 or a newer system), and data logging functions. Must display data in real-time and generate timestamped logs (output formats: *.txt, *.xls, *.xlsx, *.csv).

Key Performance Indicators:

Measurement Range: Mass flow rate from 0.075 kg/min to 18 kg/min.

Pressure Range: Operating pressure from 0 to 900 barg, nominal working pressure 700 bar.

Temperature Adaptability: Capable of measuring hydrogen with inlet temperatures from -40°C to 50°C.

Accuracy Target: Calibration uncertainty below 0.67%, with a maximum uncertainty of 12 grams for a 1kg fill.

Connection Standards: Must be equipped with H70, H35HF interfaces and a reserved H70HF interface.

Compliance and Safety Requirements:

Must comply with the OIML R139:2018 metrology regulation.

The entire system (CMU, HST, DAQ) must have ATEX explosion-proof certification for use with hydrogen.

A HAZOP (Hazard and Operability Analysis) must be conducted with a representative of the purchaser present.

Commercial and Delivery Requirements:

Basis of Quotation: DDP (Delivered Duty Paid) to a specified address in Norway. Quotations must be in Euro or Norwegian Krone and include on-site installation, commissioning, training, and after-sales service with at least a 1-year warranty, but exclude VAT and other import duties/taxes.

Delivery Time: The system must be delivered, installed, and operational (including training) by December 2026. Bidders must provide an estimated delivery timeline.

Bid Documents: Must submit a complete bid, including total price, qualification certificates (ESPD form, company registration certificate not older than 6 months, and financial statements/bank guarantee), technical proposal, warranty terms, description of subcontractors, etc. Documents must be in Norwegian or English.

Evaluation Criteria:

Quality (50%): Includes intrinsic quality, system functionality, user experience, estimated uncertainty, and relevant industry experience (e.g., oil and gas).

Climate and Environmental Impact (30%): Includes energy efficiency attributes of the delivered equipment (e.g., tank capacity-to-weight ratio) and proof of the bidder's own environmental performance.
