Objectives The objectives of this project are to: Develop appropriate technology that will easily, simply and quickly remove water from a remote location reducing customer disruption. Entry to service pipe via ECV entry point under no gas operation. A single operation to remove water from up to 20mtrs from entry point on pressures up to 75mbar Develop a methodology of recycling gas back into the network and separating water from gasProduce documents, reports, presentations and seminars to share the learning from this project . Through-out the project there will be monthly updates from Synthotech to update NGN on the progress of the project. There will be key deliverables reviews at key points with accountable parties clearly identified. The project seeks to deliver: A sufficient flow rate of water extraction for a manual system. Speed, manpower and customer disruption reductions as compared to current methodsEase of use and a target maximum training of 4 hours for competent use of the equipmentSufficiently robust hardwareOne Person operationDoes not require connection external power supply e. g. 110v/240v
Abstract Water entering the gas network creates significant network management issues primarily around the location of entry points, removal from the network and methods of removing its cause. Gas enters the aging cast iron low pressure system from a variety of sources as the pressure of the water exceeds the pressure inside the gas network. Detecting water ingress into pipes is extremely difficult, as it prevents gas escaping, our normal detection techniques cannot pinpoint the exact entry point. Water within the system creates blockages as it either fills the main system or enters smaller services this disrupts supplies to customers either individual services or multiple consumers. The current method of extracting water from services involves a two man team using an Alan Taylor unit to pump the water from the service. This is a lengthy process resulting in customer being without gas until all water has been removed there is also no way of checking that all water has been successfully removed. NGN has developed a concept which allows extraction of water from a service pipe by a single engineer and without the need for intrinsically safe equipment. NGN have now engaged with Synthotech to develop this in to a fully functioning product to safely extract water remotely from service pipes. This technical project involves developing this system so that it can that it can easily be operated by a single user on a live, low pressure (below 75mbar) network with the aim of locating the point of the blockage or restriction, removing the water and then locating the point of entry in a no gas operation in conjunction with ServiceCam. Water can also be removed with no vision in a single operation. It is envisaged that the service water extraction system will comprise of a suction head embedded at the front of the system, and an umbilical push rod method. The suction device is designed to extract the water through the umbilical push rod system. Rather than utilising the pipeline pressure to extract the water and flare the gas, the project will focus on all environmental aspects and use a novel differential pressure system to separate the water from the gas, and recycle the gas back into the network, preventing any greenhouse gas emissions.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
