Engineering design and analysis
We are providing engineering design and analysis expertise in:
|
|
- Numerical analysis - linear static; fatigue, non-linear static e.g. buckling and ultimate strength analysis, non-linear dynamic e.g. collision and grounding modelling
- Advanced structural concepts (laser welded sandwich panels and crashworthy structures)
- Safety by design (risk based design and accident consequence modelling)
- Optimization (local - gradient based methods, global - e.g. genetic algorithms, multi-criterion optimization)
- Decision support systems (multi-stakeholder/collaborative design, preference and ship design process modelling)
- Testing - test design and planning

FE ANALYSES - MOORING EQUIPMENT
|
We are providing FE analyses and reports which assure that your ship equipment fits the defined standards. The analyses and reports are available for mooring equipment.
Take a look at the pricing and the availability of the FE analyses and reports of mooring equipment.

CRASHWORTHY SHIPS
 |
|
as2on is one of the partners in an EU FP7 project SAFEWIN - Safety of winter navigation in dynamic ice which aims to develop an efficient ice compression and ice dynamics forecasting system. We are analysing the effect of ship structures onto risk of compressive ice damages. This knowledge is used in redesign of some parts of the structure to achieve the best possible damage resistance with reduction in structural weight. |
VIBRATION AND NOISE ANALYSES AND MEASUREMENTS
 |
|
We are experienced in performing forced vibration and noise analysis utilizing Finite/Boundary Element Method, providing recommendations for improvement of these characteristics to meet the IMO requirements. |
COMPOSITE PATCH REPAIR FOR MARINE STRUCTURES
|
as2con is one of the partners in an EU FP7 project CO-PATCH Composite Patch Repair for Marine and Civil Engineering Infrastructure Applications where we are dealing with the definition of a new effective repair and/or reinforcement method for large steel structures with defects.
Together with partners we conduct laboratory testing, develop numerical simulation procedures and define application cases.
We calculated stress concentration analysis in a patch.

MODELLING AND OPTIMISATION
 |
|
Our team masters FEM analyses and optimisation methods. We provided a full support in the development of an innovative design of a dredger funnel deckhouse. Design and engineering feature: parametric 3D FEM model for optimisation of panel scantlings, detailed stress assessment of all joints and their design, design for production, support in assembly and installation. |
FATIGUE ASSESSMENTS OF JOINTS
| Our team has been involved in various research and production projects dealing with fatigue assessments of welded joints. We have investigated geometrical variations of thick plate welded joints and their influence on fatigue assessment. We have planned and conducted fatigue tests under tension and bending loading conditions. |

CRASHWORTHY STRUCTURES
 |
|
One of our fields of expertise are crashworthy structures. Besides designing crashworthy ships, we have also conducted non-linear finite element simulations of a car collision in order to improve bumper crashworthiness and design. |
SANDWICH PANEL DESIGN AND ASSESSMENT
| We have been involved in several commercial projects to perform full suport in development of innovative sandwich structures designs. We performed evaluation of un-filled and filled sandwich structures in terms of weight savings at approximately equal strength properties. In addition to that, we conducted the elastic and the plastic assessments of a laser welded steel panel under different loading conditions such as impact pressure load up to the point of total collapse, etc. |
