## Summary

The National Physical Laboratory (NPL), located in Teddington, England, is seeking proposals for an RFQ titled "OWTF Very Low Frequency (VLF) Source Transducer". This procurement process is at the tender stage and falls under the industry category of Laboratory, optical and precision equipment. The tender period closes on 16 August 2024, with the contract period beginning on 16 September 2024 and concluding on 28 March 2025. The procurement method employed is a competitive quotation (below threshold), specifically suited for small and medium-sized enterprises (SMEs), reflecting the limited procurement method.

This tender presents a lucrative opportunity for businesses specialising in acoustic equipment and underwater testing systems. Companies capable of designing robust and easily deployable VLF transducers for use in various environmental conditions will find this contract particularly suitable. SMEs with expertise in laboratory and precision electrical equipment can leverage this opportunity to expand their market presence, given the requirements to deliver specialised sound energy solutions at low frequencies for NPL’s underwater acoustic test and calibration needs.

## Notice

Generation of sufficient sound energy at low frequencies requires a specialist source transducer designed specifically for use at low frequencies. NPL has a growing requirement to deliver underwater acoustic test and calibration at extended low frequencies. This extended low frequency range is to operate primarily in the region of 10 Hz to 500 Hz but with operational capabilities to extend to at least 1 kHz. The transducer is to operate as a projector, driven with conventional amplification. The transducer will be typically used at relatively shallow depths of approximately 15 m but also needs the capability to maintain performance at hydrostatic pressures equivalent to depths of up to 100 m. This new source transducer should be easily deployable, without the need for specialist lifting equipment, and be suitably robust to operate in a variety of environmental conditions. Additional information: The Authority is using the LUPC Bravo e-Procurement portal to conduct the procurement process. All Suppliers must register their company via the LUPC Bravo Portal.
