Concept-stage assessment of new technology in locomotives
...he PLC system would include fuel tank levels, odometer readings, generator power, throttle settings, and diesel engine and traction status. The role of the PLC system was to provide fuel information to the driver, such as tank levels, distance to empty and fuel efficiency, as well as to provide warnings to the driver when appropriate. At the time of this development, drivers initiated actions in response to the data presented by the existing fuel...

...urther sources of complexity, such as the existence of multiple centres of power within the organisation each able to exert an independent influence on the work. On a wider front, the services being delivered may span multiple organisations, requiring co-ordination between another set of loosely aligned but independent stakeholders. All these processes can change the priorities driving a system development more quickly than the development can be...
Read moreSimple schedule risk modelling with Safran Risk
With a view to exploring alternative tools for quantitative project risk assessment, Broadleaf reviewed Safran Risk, a tool for planning and for modelling schedule and cost uncertainty. While Broadleaf does not endorse any specific tools, we use several in our work and discussing their application provides an opportunity to offer insights into quantitative risk assessment and modelling in general.Introduction With a view to exploring alternative...

...bon dioxide is used for urea production and the cleaned syngas is used for power generation Nitrogen from the ASU and hydrogen from the gas cleaner are combined to produce ammonia, in the catalytic reaction 3H2 + N2 → 2NH3 Ammonia and carbon dioxide are combined to produce liquid urea, in the reaction 2NH3 + CO2 → (NH2)2CO + H2O Liquid urea is usually dried and shipped in granular form. The main components of the process in Figure 1 use well-prove...
Read moreBidding to construct an electricity sub-station
A contractor was preparing a commercial bid to construct a 220/110 kV electricity sub-station. This case describes a quantitative analysis conducted to provide an estimate of the effects of potential events on project cost outcomes, as an input to the commercial bid pricing decision.Summary A contractor was preparing a commercial bid to construct a 220/110 kV electricity sub-station. This case describes a quantitative analysis conducted to estima...
Read moreBio-solids treatment and reuse contract
This case illustrates a simple risk assessment to support the development of a bio-solids strategy for a wastewater treatment plant and the approval to renew a contract for bio-solids processing and reuse. It highlights factors that enabled successful outcomes to be obtained, despite commercial and operational constraints limiting the time available for preparing and conducting the assessment.Summary A primary wastewater treatment plant was due t...

...ssembled into summaries that might appear as follows. The results might be coded to show, for instance, responses from people who are employed on the operation or have a family member who is employed there (grey dots) and those who have no employment connection with it (blue dots). This information can be examined in many ways. It can be filtered by characteristics such as gender, location, the date of the contribution, whether the contribution wa...
Read moreLearning lessons where organisations intersect
Root cause analysis is successful because it imposes a structure on thinking about what, when and where a success or failure has occurred, and it generates actions that lead to future improvements. This case study concerns the construction of road tunnels close to an underground railway. Its focus is on the interface between the construction activity and existing railway assets as well as the inter-relationships between the organisations involved...

...mining equipment, ore processing plant, waste and tailings disposal areas, power plant and associated infrastructure, and camp, transport and logistics infrastructure. The case describes the outcomes from a quantitative risk analysis of cost and schedule components of the project at FEL2 (front-end loading stage 2, often called pre-feasibility, when a preferred project option has been selected for more detailed engineering). The outcomes were to b...
Read moreRisk management for a GTL proposal
A multi-national consortium was in the early stages of investigating a proposed gas-to-liquid (GTL) project. We facilitated workshops to identify and analyse the main uncertainties associated with the project. There were several objectives: to contribute to the tollgate submissions and approvals processes of the consortium partners; to enhance the quality and focus of bid preparation; and to provide a forum for communication and enhanced understa...
