Concept, FEED & Detailed Engineering

Concept & FEED Studies

Your project requires the greatest beginning.

We manage cost, risk, and uncertainty in your energy initiatives using proven, implementable concept design solutions for the whole asset life cycle.

Digital technologies enable us to rapidly and accurately evaluate and pick the optimal development solutions for your project based on your objectives and specifications.

Various KPIs are taken into account:

A Front End Engineering Design (FEED) is conducted after the completion of the concept and feasibility Study where all options will be assessed from an economic and safety perspective.

Front-end engineering and design is defined as the work required to produce process and engineering documentation of sufficient quality and depth to adequately define the project requirements for detailed engineering, procurement and construction of facilities and to support a project cost estimate. This distinct project phase is typically used to support the investment decision to sanction a project.

Onspec has executed numerous FEED for major players in the oil & gas industry and fully understand the importance of reflecting client’s intentions and project specific requirements at the FEED stage. Onspec works closely with the client team to provide definition to a level that eliminates or reduce the need for change during the detailed design and implementation stages.

FEED packages generally include:

  • svg

    Basis of Design.

  • svg

    PFD and P&IDs Diagrams.

  • svg

    Main equipment data sheets and specifications.

  • svg

    Rotating equipment datasheets.

  • svg

    Piping and instrumentation schedules and data sheets.

  • svg

    General Arrangements Drawings for main equipment and main pipework.

  • svg

    Cost estimating and level 3 project schedule.

  • svg

    HAZOP/HAZID/SIL/LOPA/RAM.

  • svg

    Project Execution Plan and EPC scope of work.

Detailed Engineering

In detailed design we convert the FEED results, tailored to the client’s execution strategy, to deliver an engineering design which can be safely and efficiently constructed, installed and commissioned:
  • svg

    Piping GA’s, isometrics and MTOs for construction.

  • svg

    Including stress analysis.

  • svg

    Electrical and control design, including power.

  • svg

    distribution and control systems.

  • svg

    Process and mechanical datasheets for equipment.

  • svg

    Civil/Structural design structure and building construction MTOs and drawings.

  • svg

    Procurement support of all equipment items.

  • svg

    Development of commissioning and operating documents.

  • svg

    Finalization and Reviewing of Piping and Instrument diagrams for construction.
