    Stichting Nederlandse Wetenschappelijk Onderzoek Instituten (NWO-I) needs a complete acoustic tracking system for its ReefXL reef restoration project in the North Sea, with an estimated maximum total value of 545,000 EUR. The system should meet specific acoustic requirements for tracking approximately 520 transmitters in a 700 × 700 m area at 35–50 m depth, support inclination/tilt and accelerometer/activity/XYZ sensors, and allow for individual traceability of all transmitters in a high-density configuration. It must also demonstrate proven capacity for autonomous subsea operation at 35–50 m water depth for up to 10 years, ensure diver-free deployment and recovery of receiver units, and achieve a target data success rate of at least 75%. All receivers and release systems must have CE marking and comply with applicable EU legislation. The award criteria are Technical Solution / System Performance (30%), Overall Planning (20%), Deployment Operational Plan (25%), and Price (25%).

    About the bid

      The Royal Netherlands Institute for Sea Research (NIOZ) seeks to procure a complete acoustic tracking system for its ReefXL reef restoration project in the North Sea. Supply of one (1) complete acoustic tracking system, with an estimated contract value of EUR 800,000 excluding VAT.

    Award Criteria

    • Description

      The Technical Solution is assessed on the following elements: • The extent to which the proposed system meets or exceeds the specified acoustic requirements for the ReefXL project, including: o horizontal tracking accuracy of at least 5 metres for approximately 520 transmitters (400 TreeReef frames and 120 Shellfish frames) in a 700 × 700 m area at 35–50 m depth; o support for inclination/tilt sensors on TreeReef transmitters and accelerometer/activity/XYZ sensors on Shellfish transmitters; o capability for individual traceability of all transmitters in a high density configuration. • The extent to which the system demonstrates a proven capacity for autonomous subsea operation at 35–50 m water depth for up to 10 years (transmitter lifetime). • The extent to which the Tenderer demonstrates experience with comparable subsea acoustic monitoring deployments in marine research or institutional offshore projects. • The degree to which the proposed receiver array and release strategy effectively ensure: o diver free deployment and recovery of all receiver units; o reliable data collection before and after storm events, with a target data success rate of at least 75%; o CE marking and compliance with applicable EU legislation for all receivers and release systems.

    • Description

      • The extent to which the planning gives the Contracting Authority confidence that: o the planning is realistic and achievable within the stated timeframe; o the sub phases (system design finalisation, factory acceptance testing, preparation for shipment, delivery) will be delivered on time; o the invoice can be issued and be ready for payment by NIOZ no later than 28 December 2026; o final delivery and commissioning can take place no later than 1 May 2027. • The extent to which the Tenderer has accounted for contingencies such as: o equipment lead times and supply chain risks; o weather windows for testing and commissioning activities (where relevant); o coordination with NIOZ’s internal planning and availability of key staff.

    • Description

      The Deployment & Operational Plan is assessed on the following elements: • The extent to which the Tenderer demonstrates a clear and safe methodology for: o delivery, installation and commissioning of the acoustic tracking system at the NIOZ location and/or designated deployment site; o integration with the TreeReef and Shellfish frames (provided by NIOZ or third parties); o support to NIOZ during the initial operational phase. • The extent to which data management, remote monitoring capabilities, and servicing procedures are described in a complete, logical, and SMART manner, including: o support for selection and implementation of suitable (open source) triangulation software; o advice on battery requirements and energy calculations for the receiver system (including 20% safety margin for cold North Sea winter conditions); o approach to training NIOZ staff and providing documentation. • The extent to which the plan addresses communication with the Contracting Authority during and after deployment, including reporting on system status and data quality. • The extent to which risks (e.g. equipment failure, data loss, battery degradation, delays in delivery) are identified and mitigated.
