Contract for the supply and maintenance of Gas Detection Equipment

Northern Gas Networks are seeking to establish a contract with a single supplier to supply and maintain/service circa 200-250 gas detection units for use on their network across the 7 year contract term.

The contract will be awarded for the initial term of 3 years with the option to extend a further 4 x 1 years.

The gas detection unit MUST as a minimum meet the following criteria and be ready to use on the gas network at the point of contract award:

• Have an infrared sensor
• Must have a GPS and Bluetooth Interface as we wish to be able to track the resources route when surveying sites, with the device able to plot both route swept and any readings that are

detected on a print out / digital report that can be uploaded to a cloud dashboard

• Have colour and audible alarm indicators
• Must be able to detect readings from 1ppm to 100% vol of gas
• Must be able to perform a gas quality check to determine type of gas being detected (mine, swamp, sewer or natural gas)
• Must be able to detect all of the following - Carbon Dioxide, Methane, Propane, Butane, Hydrogen Sulfide, Carbon Monoxide and Ethane
• Must be ATEX approved as is used in gaseous atmospheres, ideally the devices will be explosion-proof
• Must be portable and light weight, with a clear, easy to read and use display (even in dark / night)
• Will ideally include a strap for carrying around neck when operational
• Must be able to be charged in operational vehicles
• Must have an in vehicle cradle for when in transit in NGN vehicles
• Must have a range of attachments that can be used on site when undertaking site surveys
• Must have a long handle for reaching heights
• Must have a probe that can facilitate "pulling gas from the ground"
• Units proposed must have the capability to be serviced by NGN resources
• Units proposed must have the capability to run for several months without the need for calibration on a monthly basis, thus negating monthly visits to the depot for all NGN operational resources - this will also save on gasses to calibrate seekers, which further reduce running costs

If you would like to express you interest in the above opportunity please do so by emailing Ashley Haddock ([email protected]) by no later than 10am on 28/08/2022.

Any expression of interest received after this date & time will not be accepted.
