UK Public Sector Contracts & Tenders

Scope of this Contract/Procurement relates solely to the purchase of Gas Detection Units & Personal Alarm Monitoring System (PAMS) Northern Gas Networks (NGN) has consistently deployed Teledyne Gas Measurement Instruments Ltd equipment for several years, with all operatives trained on this standardised kit. Maintaining a single, familiar equipment type is central to minimising user error and ensuring consistent operational safety. NGN's workshop depots provide minor in-house servicing, repair enabling efficient turnaround and continuity of operations. Replacement units are issued during servicing to avoid downtime, supporting uninterrupted field activity. The main deliverable of this procurement is the continued supply of approved Gas Detection units and PAMS, with future purchases made on an ad-hoc basis to replace equipment that is beyond economic repair due to wear or damage. Retaining the existing supplier avoids the need for retraining, prevents inconsistencies between differing equipment types, and mitigates the increased risk of cable strikes associated with unfamiliar tools. The purpose of this procurement is to maintain a reliable, standardised, and safety-focused equipment base across the full NGN geography, ensuring continuity of service, operational efficiency, and effective cable-strike prevention.

Northern Gas Networks (NGN) have a requirement to secure the services of a travel management company. NGN have approx. 1400 employees with offices spread throughout the north of England.

Scope of This Contract This procurement relates solely to the provision of Airtime and Webhosting services following the expiry of the initial installation period. It does not include the purchase or installation of Abriox loggers. The Webhosting service element also covers the associated PressureTrac server, licensing, and data management fees required to support ongoing logger operation. Procurement Description - Abriox Logger Airtime & Webhosting Services Abriox loggers are widely deployed across the NGN network and are used to collect essential operational data. Their functionality supports two key areas of network management: A. Cathodic Protection (CP) Pipeline Monitoring Abriox loggers are installed at Cathodic Protection test points across remote areas of the network. They remove the need for monthly physical site visits by automatically recording CP readings and transmitting them to a central system on a daily basis. The devices also generate SMS alerts when readings fall below acceptable thresholds, enabling timely intervention. B. Pressure Management Abriox loggers are also used throughout the NGN network to capture and download pressure data. When originally procured and installed, the associated Airtime and Webhosting services were included within the respective supply and installation contracts. Upon installation, each logger includes an initial 12 month Airtime and Webhosting package. The SIM cards provided at installation cannot be replaced or changed during the operational life of the loggers.

Northern Gas Operates 37,000km of gas pipe and is responsible for distribution of gas to homes and businesses across the North of England, an area covering West, East & North Yorkshire, the North East and Northern Cumbria. 1190km of the network is High Pressure (HP >7 bar) Local Transmission System (LTS) which to comply with the Pipeline Safety Regs (PSR 1996) and IGEM/TD/1 Ed. 6 must be surveyed every 2 weeks in order to report on any activities or changes in and around the pipelines. NGN has an obligation to fully survey its LTS pipelines, to identify building encroachments, ground movement, activities, or potential activities by third parties in close proximity to a pipeline or specific main. A key requirement of the survey is to ensure that third parties do not damage, interfere or cause an escape of pressurised gas from NGN's asset. Aerial surveillance is an established and effective method of surveying long lengths of buried pipelines to identify threats. Aerial Surveillance is deemed as an essential safety related service for NGN.

Northern Gas Networks identified the need for a framework of contractors focused on future Capital Expenditure (CAPEX) investments related to our 'facilities' building stock. Suppliers awarded under this framework proved through tender process that they can provide or a range of minor fit outs, various building improvements, through to comprehensive construction projects. The scope encompass' a variety of commercial building types focusing on the offices and depots throughout the network. Awarded suppliers will be expected to mini tender for each project should they wish to be chosen.

NGN's QVD (Quality Vendor Database Framework) is a series of contracts related to the supply of products and equipment for use in Capital Projects undertaken across the NGN Network. A tender has been completed with the intention of awarding a Framework to various suppliers for the supply of equipment. Limited suppliers were awarded a place on the Framework to supply PRI equipment, Housing & Cabinets and Metering and therefore there is a need to award contracts to ensure that there are enough suppliers contracted under the Framework.

Northern Gas Networks (NGN) established a contract for the procurement of CCTV cameras c/w monitoring of this equipment. NGN will be extending this contract to enable the monitoring of the cameras to continue until 30th June 2027. The purchase of these CCTV cameras was a bespoke build for NGN's requirements, these camaras are monitored by the supplier's Alarm Receiving Centre (ARC). NGN will also be varying the contract to repeat purchase 5 further CCTV cameras, along with 3 solar camera trailers and monitoring of this equipment. Varying and extending the contract aligns with NGN's strategy to align all NGN's security timeline wise, enabling NGN to streamline processes and procedures with regards to security by June 2027. Moving away from the current situation. Changing supplier at this stage would bring about: incompatibility of equipment and an additional ARC to be managed by NGN, along with delays to the process possibly bringing about additional costs to current site security requirements.

This contract for the provision of Steel Crimped Fittings is for a single supplier to support Northern Gas Network's in delivering a large portfolio of operational projects and works orders.
