Engineering & Design

Based on the operating and process default values, our experts in the areas of mechanical engineering and equipment selection determine the mechanical details of the equipment to be used.

Our knowladge and experience in design is based on European and international codes, standards and engineering practies and allows us to best serve our clients project needs.

On the basis of the basic engineering, in detail engineering we prepare the concrete requirement profile of the equipment and guidelines for the manufacturer in the form of specifications, pre-layout design and general arrangement drawings.

The level of detail and the scope of the prepared documents depend entirely on your individual needs.

ZONE ENGINEERING B.V. can asset you in the area of equipment procurement. We can completely take over procurement depending on the type of project.

3D piping modeling of process facilities is a key element in ZONE ENGINEERING B.V. package. We integrate all relevant engineering disciplines design into one single 3D model, which allowing controle to be maintained during the design chain and increased the design efficiency.

Our piping engineers are characterised by many years of experience in piping design, they are knowledgeable in the project and turnkey business.

For an existing plant, we use 3D laser scanning which allows the on-site surveying to be taken over into digital documents to be integrate in 3D AutoCAD tools.

In the area of detail engineering, our teams develop true to scale 3D models of future systems and prepare concrete arrangement and piping plans as well as isometrics with bills of materials.

With the help of the most modern CAD systems, we are in the position to reproduce your project specific individual requirements and demands in Detail.

Every piping system is subjected to different loads during its design life which develops stresses in the system. To ensure the safety of the installation, the piping system needs to be stress analyzed to meet the requirements of the design code.

Piping Stress Analysis is one of ZONE ENGINEERING B.V. core business. We use CAESAR II The world’s most widely used pipe flexibility and stress analysis software, CAESAR II is a complete solution that enables quick and accurate analysis of piping systems subjected to a wide variety of loads, taking into account weight, pressure, thermal, seismic and other static and dynamic conditions, based on user-defined variables and accepted industry guidelines.

Our pipe stress engineering team is well-versed with international codes such:

ASME B31.1 (Power Piping)

B31.3 (Process Piping)

B31.4 (Liquid Transportation)

B31.8 (Gas Transmission and Distribution Piping systems)


Stoomwezen RToD codes
