ANALYSIS AND CALCULATION
To document that something works as planned before it is built, tested or before an operation is performed, the use of engineering skills is an effective tool. Based on sketches, drawings, descriptions and models, an engineer can perform calculations to check that something is floating, is stable, that something does not break or collapse, that over time, loads do not spoil anything, etc.
The results from analyses and calculations can be used to select materials, optimize structures, define the most suitable methods for installation, streamline consumption, in risk assessments and for documentation in connection with certifications and approvals of products and installation methods. The level of detail of an analysis is usually related to the risks associated with the final result, and cost – benefit.
BEIN Engineering is well acquainted with methods and tools that allow us to assist in most stages of the project, in several disciplines and we can make recommendations for a most cost-effective process.
BEIN Engineering is well acquainted with methods and tools that enable us to assist in most phases of a project, across disciplines. We can also provide recommendations for achieving the most cost-effective process possible. At BEIN, we have experience with many different types of analyses and calculations.
Statics and Strength Calculations
Projects and tasks often begin with simple hand calculations or the use of software such as ColBeam to establish a basis for evaluating what works and what doesn’t.
This is typically documented in programs like MathCAD or MS Excel. Such methods are often sufficient in the early stages of a project and for less complex structures.
As the project progresses, it is natural to employ modeling, simulation, and analysis that are better suited to the specific environment and application. For detailed strength calculations and fatigue analyses, FEA (Finite Element Analysis) is used for both linear and non-linear evaluations. These analyses can also be applied to simple beam structures.
For complex beam constructions with a large number of beams and loads, it is appropriate to use dedicated beam calculation software such as STAAD Pro or similar.
Often, a combination of these methods is required to sufficiently document structural integrity.
Pressure Equipment
We assist our clients with calculations for pressure equipment. These calculations are strictly governed by regulations set forth in the Pressure Equipment Directive (PED).
In this work, we typically begin—as with other structural analyses—with hand calculations and simpler analysis tools, and we use software such as Intergraph Visual Vessel Design or similar for more detailed analyses.
Knowledge and experience with this software allow us to perform checks on both small and large pressure vessels and other pressure equipment in accordance with relevant standards.
This provides great flexibility for efficient analysis across different material grades, pressures, and temperatures. Visual Vessel Design also enables fatigue analysis and consideration of various environmental factors. The software provides a solid documentation basis, which is essential for CE certification of the equipment.
At BEIN, we have extensive experience in performing analyses and strength calculations for steel structures exposed to static and dynamic loads in demanding environments.
Our core competencies in statics and strength calculations include:
- Strength calculations with static and dynamic loads
- Fatigue
- Beam calculations of composite structures
- Pressure tanks
- Reverse engineering
Analyses and calculations are most often part of a study and/or detailed design phase in a project.
Occasionally, reverse engineering is performed—a working methodology where, starting from a finished product or solution, documentation is created through measurement, photography, 3D scanning, and reporting.
This is then analyzed and may replace all or part of a traditional product development process.
BEIN has experience with technical documentation of existing facilities or operations, where we have assisted with photography, measurements, and 3D scanning.
This material has subsequently been used as a basis for P&ID drawings, layout drawings, design of new equipment, or for the implementation of other adjacent components. For example, we may use the deflection of a structural element as a starting point to document the capacity of a structure. In these processes, we can apply simple hand calculations or more advanced software tools—depending on cost-benefit considerations, documentation requirements, and ris
Marine Operations
At BEIN Engineering, we have extensive experience with various marine operations, combining both theoretical and practical approaches. We have particularly strong expertise in the preparation and execution of umbilical and cable laying, as well as marine lifting operations. Preparations for such operations often include static and dynamic analyses related to the product being installed, handling equipment, and supporting structures.
Calculating accelerations on board a vessel is often a necessary input for lift analyses to ensure a safe installation that avoids adverse consequences for personnel, the product being handled, or the equipment used. BEIN Engineering uses software such as Orcaflex as a tool for installation analyses. Notably, we have developed a method for transferring complex structures from design software into Orcaflex to streamline and clarify the workflow. This process, which was previously time-consuming, can now be completed with a few simple conversions. Orcaflex is a versatile analysis tool for pipe, cable, and umbilical pull-in operations. It is also valuable for analyzing lifting operations from vessels through the splash zone.
Simpler, yet often sufficient, are spreadsheet-based calculations using standards such as those from DNV-GL, which provide a good and conservative approach.
Hydrodynamics
At BEIN Engineering, we have extensive experience with the marine environment and perform analyses and calculations on structures and systems exposed to demanding conditions. As previously mentioned, we have solid experience with cable analyses and the use of Orcaflex for numerical analysis.
Other Analyses and Calculations
Occasionally, specific types of calculations and analyses are required. These may relate to fluid flow (Computational Fluid Dynamics – CFD), VIV analyses (Vortex Induced Vibrations), electrical installations, and more.
BEIN Engineering has experience delivering a wide range of analyses and calculations for various purposes. We also collaborate with several partners who can assist when needed
