Faced with the challenge of reusing heat waste from a refinery to supply a new district heating network, InSite is conducting a global project in partnership with a local energy company.
The concept phase includes carrying out a proof of concept for various heat sources, followed by a feasibility phase that quantifies heat inputs through flow modeling. A cost estimate, validated by a Monte Carlo simulation, makes it possible to establish a robust financial base (AACE Class 4, with a margin of +50%/—30%). Subsequently, the project evolves to the FEED phase and then to detailed design, integrating the early determination of connection requirements and risk management, while closely involving the stakeholders of the refinery.
Rigorous monitoring, transparent change management and detailed model reviews promote seamless alignment of deliverables to effectively support the construction phase and ensure the success of the district heating network.
The customer expects global support to exploit the heat waste from the refinery and convert it into a reliable source of district heating. The solution must allow for a rigorous design, integrating a reliable financial estimate and planning adapted to connection constraints and scheduled shutdowns. The strategy aims at effective risk management, smooth coordination between InSite and refinery stakeholders, and the provision of validated deliverables to support the construction phase successfully.
Ensure a complete design of the network, from feasibility to detailed design.
Guarantee a financial estimate and schedule adapted to the constraints of the project.
Coordinate closely with the refinery to anticipate operational impacts.
The mission focuses on the complete integration of the design phases, from the initial concept to the detailed design, for an innovative district heating network. It includes the creation of flow models, the estimation of costs by simulation, the early definition of connection requirements and the proactive management of risks. InSite's role is to ensure the technical consistency of deliverables and the coordination of teams in order to secure the transition between phases and effectively prepare for construction.
Develop flow models to quantify heat sources.
Validate the cost estimate using a robust Monte Carlo simulation.
Coordinate the transition between FEED and detailed design to secure the project.
