Preliminary planning / Feasibility studies

Feasibility studies

Feasibility studies are performance phases that we offer to our customers and partners. These are comprehensive studies and serve in detail to identify information of a project. It takes into account risks, points of view and conditions such as time frame, costs and quality.
The aim of a feasibility study is to determine whether the project will be continued, redesigned or completely given up.

Following points will be worked out in exchange with our customers:

    • Determine the physical properties, chemical resistants materials and special requirements.
    • Determining the physical and chemical feasibility
    • Risk assesment
    • Consideration of profitability and amortization

    Basic- and Detail Engineering

    Basic Engineering

    The design is based on the objective of a project. It leads to a work status of the documentation, with which the system to be designed is sufficiently defined for the actual execution.

    The definition must be sufficient to describe performances qualitatively, to calculate costs incurred, to inquire services from subcontractors and to prepare appropriate official documents.

    When planning the design, all parties involved in the project are informed comprehensively at the kick-off meetings about the state of planning, in order to ensure a smooth process. At these meetings, it is important to us to avoid misunderstandings and plan together in a structured way.

    For these reasons, we give importance to a structured approach:

    • The level of planning, e.g. 
      → Thermal process
      → Peripherals
      → Scope of complete project
    • The form of execution
      → Topic
      → Suggestions
      → Technical discussion and result.
    • Definition of tasks and their responsibilities.

    Detail Engineering

    Continuing and deepening the design is the Detail Engineering. This is to provide all documents for installation, operation, commissioning and service.

    To start the execution, the following criteria apply:

    • Basic engineering in sufficient quality
    • Approvals of involved authorities 
    • Agreement of customers management
    • Completed and clear revisions of the finalized draft

    The timing and organization of the detail engineering depends on the overall scope of the project.
    We define the conditions for the temporal coordination as important milestones.

    We perform the duties in following order:

    • Technical implementation of conditions and knowledge
    • Receipt of final specifications / performance lists of the customer
    • Match the entire planning
    • Selection of subcontractors
    • Plan, classify and design pipeline lists, supply and disposal networks
    • Inquiry and quotation phase
    • Plant design and controlling manufacturing  plans
    • Overall planning of the installation
    • Finalization of execution documentation
    • Planning control as a continuous action and
      revisions on-site in case of deviations

    Automation, HMI Visualization,
    PCS-process support

    The digital automation is for the operation of processes and process plants in factories, with minimal human intervention, and is nowadays indispensable.
    We deliver process plants with their own control system. After commissioning, the programm will be provided to the customer.
    However, it may happen that the systems control need to be implemented in an existing customer PCS (process control system) in the manner of the Industry 4.0 Evolution.
    We support our customers in such processes and offer these as an independent service, including documentation and remote diagnostics together with their cooperation partners.

    For the program we prefer SIEMENS Step 7, TIA Portal.
    For HMI / displays we use ProTool, WinCC Flexible, InVisu.
    In online remote diagnostics and online updates for the programs, we  work with the classic VPN tunneling, the convenient and

    safe SINEMA RC system from SIEMENS.

    Commisioning, FAT / SAT

    Pre-Commissioning

    After the installation and assembly phase and before delivery, the mechanical and electrical installation will be pre-inspected by our skilled engineers and workers.

    We perform the following aprovements and issue corresponding test certificates and protocols:


    • Preliminary checks according to the latest VDE standards and regulations
    • Electromechanical and mechanical safety devices
    • Tightness control of systems and pipes under pressure
    • Digital / analogue input and output testing of components within the skid
    • Rotary field of motors up to opening and closing of automatic valves
    • Simulation of alarms and their interlock, taking into account, even the visual visibility via the HMI.
    • Individual functions of the modules and their interaction with eachother
    • if necessary preliminary examination of the cleaning / CIP (cleaning in place) / SIP (sterilization in place) conception
    • Parameter recording of operation with water or appropriate test media.


    After the internal pre-acceptance, it is possible  to carry out a
    FAT (Factory Acceptance Test) with our customers.

    Commissioning

    Commissioning takes place at the end customer or operator at the planned installation site.

    If pre-commissioning has been carried out, the connecting and connecting interfaces can now be checked and logged accordingly.

    However, the following work is carried out before commissioning the product:


    • Final acceptance test according to the latest VDE standards and regulations (if necessary by the customer)
    • Re-testing of leaks of systems and piping under pressure and vacuum
    • Digital / analogue input and output test of the remaining sub-installed components or perepherals
    • remaining alarm simulation
    • Rotation direction of motors
    • Parameter and power consumption of operation with media provided by the customer.

    After commissioning with product, and after the personnel briefing,

    finally a SAT (Site Acceptance Test) can be carried out on site.

    Training of personnel

    Experience has shown that a process plant can only function as efficiently and trouble-free the plant operator or the maintenance personnel is taking care of it. It is often the case that in the event of a personal change or replacement of operators, the plant experience or know-how is not transferred. Due to not knowing how to handle the plant in certain situations, risks of accidents possibly even unexpected expenses and repair costs arise. This makes the training of operators and supervising specialists indispensable.

    After each start-up, we assign the appropriate persons and groups. Even after a final acceptance, briefings and training can be done at any time.


    The information will be provided as follows:


    • Plant technology based on process diagram P&ID and live on the plant
    • Explanation of the individual modules and their functions
    • Corresponding guidelines and legal regulations
    • Outgoing dangers and risks or explanations from the risk assessment of the plant
    • Special features of the system
    • Operation of the HMI and of the plant
    • Functional sequence of the individual programs and subprograms
    • Fixed set points and actual parameters that need to be checked and documented regularly
    • User manual
    • Classic cases of possible malfunctions and their corrections and explanation of their cause
    • Recommended spare parts and recommendation of preventive actions
    • Maintenance plan and regular inspections
