We offer a diverse range of services to cater to our clients’ specific needs and requirements. Our commitment to customer-driven design and innovation is at the heart of everything we do. 

Customer Driven Design

We understand that every project is unique, and we embrace the challenge of custom-tailoring our solutions to meet your specific goals. Our customer-driven design approach ensures that we work closely with you to bring your ideas to life and create solutions that perfectly align with your vision.  

Precision and accuracy are key to our engineering solutions. Our team utilizes advanced ANSYS calculations to perform comprehensive analyses, ensuring that your project meets the highest standards of performance, safety, and reliability.

We know how to comply with Eurocodes and DNV design codes with respect to stresses and buckling stability. It is not always necessary to perform finite element analysis, so we do master the use of pen and paper if this is sufficient for manual calculations.

We have experience of design of welded structures in aluminium according to Eurocode 9. Be aware the reduction in allowable design stress in HAZ for the welds.

Offshore spools are one of our specialities. We use ANSYS APDL to create the in-place model of spools. The APDL model is parametric and hence, the model can include every possible combination of fabrication and tolerances. We have in-house macros in ANSYS APDL to do the fatigue analysis due to VIV (Vortex Induced Vibration).

We can perform design calculations of pressure vessels, valves and other pressure components. We can comply with the following design codes: ASME VIII, API 6A, API 6X or EN 13445.

We have long experience of stress analysis of composite materials. We consider composite materials as a regular construction material which can in many places replace more traditional use of steel. They are strong, light and has excellent resistance in corrosive environment.

Fiber glass has anisotropic properties and in contrast with the metals has unequal mechanical properties in all direction. In the structures that is made of fibre glass materials, it is important that the fibre is used in the direction that is most useful for the strength. Therefore, there is possibility to reduce the weight of the structure significantly. In addition, it is possibility to have any shape or curvatures for structural parts.

We are also a committee member of writing the new version of the SN-CEN/TS 19101 “Design of fibre-polymer composite structures”.

Polyurethane is a very durable and useful material. The behaviour of this material can be simulated in Ansys. The material can be stretched several hundred percent. But when compressed it behaves almost like an incompressible fluid. With very large strains and deflections the elements might become very distorted. This will cause convergence issues. The method to overcome is to use adaptive meshing and re-meshing during the solution process in Ansys.

We perform sea fastening calculations and rigging design in very short time, if necessary.

Do you have a very challenging lift subsea? What if the rigging where very elastic? Then this might increase the weather criteria for the operation. This is indeed possible to do! Have a look at the picture below. Inserting cylinders of polyurethane inside a Dynemaa rope gives a very soft lifting sling.

We can calculate do drag- and lift-coefficient for various structures. For shallow water, the wave loads become very large. We use the OpenFOAM for flow analysis. We use OpenFOAM® for flow analysis. OpenFOAM® (Open Field Operation And Manipulation), based on C++, is a free and open source CFD toolbox. Unlike commercial codes OpenFOAM® is not a black box, the user can control and modify each of the steps of the solving process by changing the source code. This is a great advantage, since several modules include data conversion from and to commercial CFD codes (Ansys®, Fluent®, CFX®) or formats (VTK), allowing cross validations. There are almost no limits for what OpenFOAM can simulate.
