Plant design

Success through interdisciplinary cooperation.

HINE offers professional interfaces to mechanical and apparatus engineering, electrical engineering and automation as well as civil engineering.

In a plant, a developed process is made technically usable by a planned systematic assembly of apparatus, piping and instruments that represent the desired process. The planning of a process plant is always an investment in the future of a company. On the one hand, this concerns the investment in the realization of the plant, on the other hand, it also concerns the operation and maintenance after the start of production. Your investment is in safe hands thanks to HINE’s knowledgeable experts.

Plant design and construction are highly interdisciplinary tasks. Depending on the plant, experts from a wide variety of fields are needed, including mechanical and apparatus engineering, electrical engineering and automation (EI&C), and civil engineering. HINE’s project managers and specialist planners form the central interface and coordinate the cooperation between the various disciplines.

The core of plant engineering is still the efficient combination of plant components in order to run certain process steps in it. The combination of the individual process steps results in the overall process, which ensures the production of the desired substances in a consistent quality. In order to plan a good plant, an overall understanding of the process and the interactions of the individual plant components is necessary. Our engineers have a wide range of knowledge and experience in order to be able to make these overall technical considerations.

Plant design for all

The planning of a plant is almost always a unique and targeted project. Even if certain processes are similar in every plant planning, there are usually so many different boundary conditions and requirements that a plant can only be sensibly realized in the form of a project. This also allows a broad orientation of plant planning, independent of a specific industry. We plan plants for the chemical, pharmaceutical, energy and food industries as well as for all operators of process plants who want a solid and efficient design of their plant.

We design your plant based on your defined requirements. We manage your project so that you are always informed about the current status and can control the project. We plan the plant in all planning phases from preliminary planning to execution planning.

Project Management

With HINE’s project controlling, you always have your project under control.

We plan process plants for the energy, chemical, pharmaceutical, life science and food industries and for anyone who wants a solid and professional design of their process plant.

Since plant design is handled as a project, it requires solid project management that ensures information management, communication and coordination of all parties involved. HINE’s project managers not only coordinate the internal work, but also coordinate sub-planners and external trades. Furthermore, they work closely with the client and operators to ensure that the project is moving in the right direction.

In addition to information management, you must continuously monitor and control compliance with defined project objectives such as deliverables, delivery dates and project budget. HINE has its own tools for project controlling, which are an integral part of our day-to-day project management activities and thus ensure robust monitoring of the project’s success. This provides our clients with transparent insight into the current status of the project at all times.

Compliance with project objectives is also affected by external influencing factors. Therefore, monitoring is primarily concerned with identifying deviations from the objectives at an early stage so that appropriate countermeasures can be taken and implemented together with our clients. In this way, our clients are able to control the project in a goal-oriented manner and to determine the success factors of the project themselves.

Conceptual, Basic and Detail Design

HINE’s engineers ensure the technically efficient and economically profitable development of your process. We plan your plant in the phases

  • Conceptual Engineering,
  • Basic Engineering and
  • Detail Engineering.

We develop your plant in all planning phases, from preliminary planning to design planning and execution planning. Based on the fundamentals determined by process engineering, such as the process concept, the specifications and the feasibility study, the optimal realization of the process is determined in the preliminary planning. In addition to the technical process, safety and economic aspects are also taken into account. In the preliminary design, a block and process flow diagram is developed, the substances and media involved in the process are determined, the main equipment is specified, an installation plan is drawn up, and a safety concept and an initial cost estimate are provided.

The design planning builds on the preliminary planning and aims to develop a consistent and feasible concept for the plant that can be used to map the desired process. In the process, the energy and material balance of the process will be established and the P&I flow sheet will be developed. The safety and functionality of the design will be considered using an appropriate risk assessment, such as the HAZOP or PAAG process, and the design will be further improved. Furthermore, the materialization of the system is already being specified. Long-runners are identified and the plant standards on which the design is based, such as pipe classes, are transferred to the design. Finally, scheduling for the subsequent phases and a further specification of the cost estimate are already carried out here.

In the implementation planning, the plant is further detailed so that the project can be realized. The plant components, piping, fittings and instruments are specified until they are ready for ordering. Furthermore, stress calculations of the supports and secondary steelwork are carried out. The planning is supported by specialized software solutions for CAD (computer aided design) and BIM (building information modeling). With the help of these programs, a digital image of the plant is created. The plant layout is converted into a 3D model and the information on the plant components is stored in a central database. From this, extracts of the installed components as well as isometrics can be derived, which are good for manufacturing or ordering.

Depending on the initial situation, the approach to 3D CAD planning differs. If it is a conversion or an extension of an existing plant (brownfield), the interference contours of the existing plant components and the periphery must first be recorded. The recording of the existing plant is done with the help of a 3D laser scan. The transfer of the interference contours into the 3D planning helps to avoid collisions in order to reduce the risk of unplanned costs and schedule delays. For greenfield projects, i.e. a complete new building on a greenfield site, this problem does not apply. Nevertheless, the same methods and software solutions are used in the planning process.

HINE engineers have the expertise and experience to plan your plant from the ground up. We act as an interface to the other specialist departments EI&C and construction and ensure a smooth planning process and solid planning for the implementation of your project.
