Gas Engineering Consultancy and Capacity Building

Gas network infrastructure, including upstream gas transportation, storage and processing, high-pressure gas transmission pipelines in the midstream, and low-pressure gas distribution networks downstream, are all important links in the gas chain transporting gas from the field to the consumer. The design, operation and maintenance of gas network infrastructure is crucial to both the operational process of delivering gas to consumers and the commercial characteristics of a project. For example, not only are gas transportation costs closely monitored by regulators and consumers alike, but a failing or poorly designed network can cost millions of pounds to fix.

MJMEnergy has provided a wide range of gas engineering consultancy and capacity building around the world, including network analysis of transmission and distribution, feasibility studies on gas storage projects, and advice on gas safety with regards to internal pipework.

Consultancy Projects:

The following titles are examples of some of the energy consultancy projects that we have carried out in this area of expertise. (Clicking the title will provide more information.)

  • Network analysis of a gas transmission pipeline
  • Network analysis of a gas transmission pipeline

    MJMEnergy, in conjunction with an international energy consultancy, undertook an extensive survey of a high-pressure gas transmission pipeline that was failing to meet its design capacity. This work included a detailed review of the pipelines pressures, flows maintenance and incident logs. In addition, the capacity of the pipeline with its multiple inputs and off takes was analysed using network analysis software. This resulted in a diagnosis of the capacity constraint as a result of poor quality procurement of pipeline materials during the construction phase. The areas of work involved in this analysis included the following areas:

    • Data gathering phase - This stage involved gathering all the relevant data on the pipeline, including its design specifications and maintenance history.
    • Network analysis - This involved building a traditional network analysis model of the pipeline its delivery and offtake points and running a series of scenarios.
    • Identification of bottlenecks - By analysing the network analysis data in conjunction with the operational data, it was possible to identify where the capacity constraints were and why.

  • UK Gas Storage Feasibility Study
  • UK Gas Storage Feasibility Study

    The purpose of this feasibility study was to provide estimates of capex, opex and potential income that would result from converting a disused mine into a gas storage facility for operation in the UK gas market. This project involved understanding how the technical and commercial aspects of gas storage in the UK linked with a detailed geological understanding of the potential asset itself. Therefore we developed a bespoke team that consisted of experts in the technical and commercial aspects of gas storage, gas compression and geology, working with WYG.

    In order to establish both the technical and commercial feasibility of the project we developed two work areas. The Technical Team undertook a review of the disused mine as a potential gas storage facility with detailed examination in order to establish its potential technical characteristics. In parallel the Commercial Team, following an analysis of the gas storage market in the UK, developed a gas storage valuation model. Then using the characteristics provided by the technical team, established a potential NPV for the project based on the intrinsic and extrinsic value of the asset. Given the aspirations of the client to ultimately sell the asset the main deliverable was a high quality feasibility study for review by potential purchasers. The final report therefore clearly set out the options open to potential purchasers for using the disused mine as a gas storage facility with associated costs and potential incomes.

  • UK Apartment Block Gas Supply Replacement
  • UK Apartment Block Gas Supply Replacement

    Following the discovery of safety concerns with gas mains in a 1970s block of 85 luxury flats in London, MJMEnergy negotiated with the gas transporter and its contractors over the least intrusive and most effective way of replacing the complete gas main and supply up to the consumer meters. The project required much research into the intricacies of the building construction, and the difficulties of replacing a centrally installed gas supply system put in to old standards during the original build. Visits to site were reinforced by individual inspections of each dwelling, and a summary of the design of each flat and its possibilities.

    Initial meetings with the Building Manager and the Property Company Directors set the scene for a good understanding of the brief. Discussions with the transporter and their contractors identified the different views on how the pipe replacements could be achieved, with conflicting requirements over the location of new pipes. Eventually after much research into different possible solutions, ones were found which did not involve the unwelcome prospect of many risers up the side of the building - which although not listed, is in a conservation area. These bridged the gap between the otherwise conflicting views of the transporter and the owner. The work has now been carried out.

  • Review of Gas Safety Standards, Reports and Recommendations
  • Review of Gas Safety Standards, Reports and Recommendations

    Complete review of a report on a gas installation in two large blocks of flats in London, following concerns by the Health and Safety Executive about the lack of adherence to the standards in place at the time and possible dangers to the occupants. The project required researching all the available Gas Standards and Gas Acts, Building Regs, IGEM Gas publications and pipeline safety regulations (23 in total). Both those current and subsequent issues of the standard and regulations were then applied to the design and installation of the gas supply network in these large blocks of flats. Among many subjects covered were pipe entry requirements, the quality and appropriateness of risers, laterals and valves, and the incorrect installation of meters. The appropriateness of the remedial work necessary was also reviewed.

    Besides reviewing and validating the previous report on the installation, the consultancy work summarised the standards in place when the project was tendered, those when it was built and those current at the time of the study. This led to the Client having confirmation of the whole scenario, including a measure of how the installation was to be put right, and how accountability could be allocated and disputed.

  • Myanmar LNG Import Project
  • Myanmar LNG Import Project

    In order to meet the shortfall between gas supply and demand in Myanmar, the Myanmar Oil and Gas Enterprise (MOGE), considered a number of possible options for sites to facilitate LNG imports. MJMEnergy in conjunction with PEC, ECA, Drennan Marine and DCMetocean, led the project team that examined three possible LNG sites in Myanmar.

    In addition the Project Team developed a site prioritisation tool and reviewed the possibility of gas swaps. The work was sponsored by the World Bank on behalf of MOGE.
